Using a quality Central Heating System helps lower costs in running a home or a commercial space.   Not only do they save on expenses but it also plays a role to a home or business’ owner quality of life.  The boiler is considered one of the most important components of a central heating system because it is like a big fire that has continuous supply of gas.

What to Consider When Choosing a Central Heating Boiler?

There are several things to consider when choosing a boiler for your home or for your business.  First, you should take into consideration what type of fuel you would want to use.  The most common are gas and oil but gas is the more common of the two since if linked with a main gas supply, there is no need to refill the tanks.  There are also options for wood burning boilers but cleaning would be an issue.  Another thing that is important when choosing a boiler is the fuel cost and the maintenance of the system.  The most expensive system is the oil-burning system among other systems.
The size of the boiler is dependent on the size of the household.  It is also important to consider the number of rooms and the number of people who will be living in that space.  With this in mind, there are three kinds of boiler systems to choose from; the combination, conventional and the system boiler.  The most popular of the three among households is the conventional type which requires a holding tank and requires the most number of energy among the rest.  The combination may not need a holding tank and additional pipe work and this also provides hot water on demand and is the cheapest compared to other types but what the issue with this type is that it would take more time to heat up the water and can only be used one tap at a time.  The system boiler is the most expensive boiler but in spite of that fact it provides a more consistent water temperature and flow rate.

What Are the Different Types of Central Heating System Boiler?

When choosing the best central heating boiler for your needs, you have to base your decision on several factors such as noise levels, location or cost.  Here are different types of Central Heating Boilers to choose from:

Gas Boiler

When choosing gas boilers, natural gas is considered to be the best option because of its reliability and cost.  A condensing model is at least 30% more efficient than those non-condensing models.

Central Heating Solutions in Auckland

Date: Apr 16, 2019 - 1:48 am

While Auckland enjoys a largely warm coastal climate, it gets an average low of 7oC in winter and a fair share of rainfall during summer.

With the changeable weather and the big drops in temperature overnight, central heating proves to be a wonderful solution for keeping your home consistently warm while drying away any moisture that gets inside.

Central heating ensures even distribution of heat around your home, via a central heat source. It’s not a new concept but the technology has become so advanced that it’s too good not to consider. Some of the benefits include:

  • Economical to run: operational cost is around 10c per kwh
  • No forced air movements: no draughts, no cold spots, no noisy fans
  • Better indoor air quality: does not circulate dust and allergens around your home.
  • Easy and flexible temperature control via the thermostat and timer.
  • Zoning capability for ultimate control and comfort.

How central heating works

Central heating systems consist of a primary heating appliance (typically a central heating boiler), which has four main components: a burner, a heat exchanger, a blower and a flue for releasing gaseous by-products.

To make things simple, think of a central heating system as a continuous circuit that moves hot water from the boiler through all the radiators, and then back again for reheating. The water is permanently stored inside the system, so it’s the same water that circulates around your home (unless it is drained for maintenance). No water is actually consumed

In practice, here’s how a typical gas-fired boiler or ‘wet system’ works:

  1. central_heating_solution_aucklandThe boiler burns natural gas to create hot jets. This heats up the heat exchanger, which is basically a water-containing copper pipe that bends back and forth inside the gas jet chamber to pick up the maximum amount of heat (approximately up to 60oC). In the process, the heat energy is transferred from the gas to the water.
  2. The heated water is pushed through the pipes by an electric pump. Older models use gravity and convection to move water around the circuit (hot water naturally rises as it has lower density than cold water).
  3. From the pipes, the water flows in a closed loop inside each radiator (located in different parts of the house), entering at one side and leaving at the other. The radiators give off radiant heat gently, which leaves the water cooler. By the time the water has passed through
    all the radiators, it has cooled down significantly and
    must return to the boiler for reheating.

The entire operation is controlled by a thermostat and a time controller, allowing precise control over the temperature in different parts of the home. Some systems allow dedicated thermostats in each room. The thermostat switches off the boiler when the room is hot enough and turns it back on when the room temperature dips. Thermostats may be manually adjustable or electronically programmable.

Central heating systems don’t have a problem supplying heat in multi-story homes since the pump is powerful enough to push the heated water through radiators that run upstairs.

Types of central heating systems

Gas-fired boilers are common in Auckland. It is simply economical in terms of installation and running costs, since many homes are already supplied with natural gas. Houses with no connection to the gas network normally use liquefied petroleum gas (LPG) or heating oil, which is a little more expensive to run but works in the same way.

Electric boilers are more common in rural and remote areas where gas or oil is not readily available. But some households in urban areas also choose this type of system because of the numerous advantages. Electric boilers are capable of meeting the demands of much larger homes. They are much simpler in design so they’re light and compact. They are touted to be 100% efficient and run silently. It’s also more environment friendly due to its lower carbon emission. The main drawback of electric systems is the installation cost, as it will require new pipes and boiler.

Combination boiler (hybrid) systems are also gaining more attention today due to their practicality. This type of system heats water on demand, both for space heating and for domestic use. They require less space since they don’t need a feed tank or hot water cylinder.

Geothermal heat pumps are another great option because they are environment-friendly and produce the lowest running costs. They are, however, only suitable for new builds because retrofitting the pipes is extremely difficult and expensive.

Underfloor heating systems have pipes strategically laid under the floor, in lieu of radiators. The heated water in the pipes warms the floor, which in turn warms the room. It is considered efficient and highly controllable. However, it can only be installed in new homes because the pipes need to be laid in the concrete slab.

Apart from the fuel or power source, there are a few other things to consider such as the size of your home and your budget.

The best way to decide which system suits your home is to talk to an experienced and qualified plumber. Talk to us today!

Big Radiator Central Heating System Installation In Auckland

Date: Oct 9, 2018 - 12:29 am

We recently completed an installation of a big home radiator heating system for a 2 story home in St Heliers, Auckland. The home previously have a low pressure hot water cylinder, which was replaced by a gas boiler connected to the central heating system.

The new radiator central heating systems consists of:

  • Bosch 37kW gas boiler
  • 10x radiators
  • Internet enabled control system

Our team got to work on the installation which involved running Ivar insulated pipe both under the home and through the walls to the radiators both upstairs and downstairs, providing heating to all areas of the home. Ivar insulated pipe is extremely efficient pipe which is used to maximise efficiency by retaining heat while the water is transferred. Uninsulated pipe would let heat escape by the time it reached the radiators, which means not only would you have lower heating performance but it would cost you more to run as well.

residential_heating_syetsm_installation home_heating_syetsm_installation home_radiator_heating_syetsm_pipework

Once the pipework was laid out, the radiators were installed in every room of the house, excluding the bathrooms.

radiator_heating_syetsm_installation home_radiator_heating_syetsm_installation radiator_heating_syetsm_installation_2

The Bosch 37kW boiler, used for both radiators and water heating, was installed externally, behind the first floor bathroom.

home_heating_syetsm_boiler

This system has been designed to provide efficient heating to all rooms in the home, resulting is very effective heating a low cost for the home owners. The online control system brings a new convenience to controlling heating in the home, allowing the system to be controlled over the internet through the app. This means you can control the heating without even being in the same room!

What are the benefits of radiator central heating?
Radiator central heating systems provide extremely efficient heating solutions for residential homes. By combining water heating with central heating, these systems utilize an already used energy source to heat your home, while costing you much less than traditional electric radiators to run. They also provide a much more even distribution of heat in the home, which is stronger than an electric radiator, and can be adjusted quickly and easily as required.

Using Heat Pumps for Underfloor Heating

Date: Sep 11, 2018 - 1:10 pm

Underfloor heating or radiant in-floor heating is increasing in popularity among Kiwi households due to its many advantages. Not only are heated floors lovely to walk on, but they are also economical, comfortable and energy efficient to run.

Heat_Pumps_for_Underfloor_Heating

Unlike other heating methods, radiant underfloor heating encourages heat to rise up through a space via convection, rather than forcing it down. In-floor heating can either take the form of hydronic heating or electric resistance heating. We’ll focus on the first one.

Hydronic heating involves laying a network of pipes onto the subfloor and circulating a heating fluid through the piping. The heated fluid radiates heat into your floors, warming your home evenly and comfortably. Hydronic heating operates silently, which is another plus.

The fluid can be heated in various ways: by using a heat pump, using fossil fuels or electricity by means of a boiler heating unit. Heat pumps generate hot water at around 40oC, which is ideal for heated floors. On the other hand, gas and oil boilers heat water to 65-85oC, which will scald your feet. Using these systems will require mixing hot and cold water to bring the temperature down to a comfortable level, which is highly inefficient.

Air-to-water heat pumps take the heat from ambient/outside air and transfer the heat into the water via a heat exchanger in the cylinder. Some heat pump systems can be configured to provide part of the energy needed for domestic water heating.

With the integration of a heat pump, your underfloor heating system will have the potential for zoned control. This means that rooms can be heated on an on-demand basis, helping you to cut down your energy consumption. In addition, heat pumps offer the versatility of switching between heating and cooling modes for year-round comfort.

Heat pumps generally use less energy to maintain the heat when the target temperature is reached. Some units can control the temperature as accurately as 0.5oC. When there is a big difference between the desired temperature and the actual temperature, some heat pumps automatically adjust to a higher frequency to increase the temperature rapidly.

Modern heat pump technology also has a smart-defrost feature that allows faster recovery by reducing defrosting time and extending heating time. This further enhances heating efficiency. And since they are designed to work well into the winter season, heat pumps typically have inbuilt anti-freeze protection along with other protection controls, such as water flow switch protection, compressor overload protection, high/low pressure protection.

underfloor_heating_heat_pumps

In summary, underfloor heating powered by a heat pump is a convenient and efficient way to heat your home.

Installation

Underfloor heating is often integrated in the design of a new home build for practical reasons. It is easier to lay the pipes before the floors are laid than to retrofit them.

In existing homes, casting the pipes is a lot trickier as there are items of furniture and fittings in the way and some floors can be difficult to work with. For elevated homes, the pipes can be retrofitted via “diffusers” spread below your timber floor. For concrete slab floors, the pipe is attached to a mesh profile and topped with a concrete screed that may be tiled or carpeted.

As you can imagine, a more complex installation means higher upfront costs. But if you think about the comfort and long-term energy savings, a heat pump-powered underfloor heating system can be worth the investment.

Why Hydronic (Water-Based) Central Heating is Healthier

Date: Aug 6, 2018 - 12:11 pm

More people are choosing a hydronic central heating system for a number of reasons. The benefits simply stack up: silent operation, flexibility, comfortable heating, low maintenance and cost effectiveness.

But perhaps the most compelling reason for choosing this space heating method is the fact that it makes your home healthier by improving indoor air quality. This is an important benefit for New Zealand homes, since respiratory illnesses such as asthma affect 1 in 6 Kiwis. In fact, respiratory diseases are costing Kiwis over $66 billion a year and are the third leading cause of death in NZ.

why_hydronic_central_heating_is_healthierWhat is hydronic heating?

As the name suggests, hydronic heating uses hot water to distribute heat throughout the home. The heat is generated in a gas boiler and then distributed through a pipe system. Using natural convection and radiation, the circulating water warms up the household by evenly distributing a comfortable and gentle heat. Instead of warming the air in your home (like fan-forced systems do), hydronic heaters warm objects to release radiant heat.

Once the system is set up, you can forget it and it will do its job without supervision. You can adjust the temperature and create zones to ensure comfortable, on-demand heating only for the rooms you use. This, and the fact that hydronic heaters are around 30% cheaper to run than ducted systems, makes the technology an economical heating alternative.

Since it uses less energy to generate the same amount of heat, it is generally the preferred central heating system by those in cooler climates.

So why is hydronic heating healthy?

  • It does not dry out the air

Many fan-forced ducted systems tend to suck moisture from the air or cause unpleasant draughts. Dry air may exacerbate some of the symptoms for asthma sufferers. With hydronic central heating, there are no hot spots or humidity produced, so the air doesn’t dry out.

  • It prevents mould growth

Unflued gas heaters and fan-forced ducted heaters produce water vapour, which create damp areas that may harbour moulds. Moulds are a well-known trigger for allergies and asthma attacks. But because hydronic heaters reduce moisture and humidity in the air, mould growth will become less likely.

  • It keeps allergens at bay

Since hydronic heating systems don’t use fans, vents or ducts, they don’t allow dust mites, pollens and other air-borne allergens to enter your home. Most of the components are hidden beneath the floors or behind walls, so they also don’t harbour dust particles.

  • It’s healthy for the environment, too!

Hydronic heating utilises water and natural gas, and uses 70 percent less energy than other modes of central heating. You also have the option to use solar power to heat the water, which improves energy efficiency. Additionally, the system allows you to create zones so you can heat specific rooms on demand rather than heating the entire home at once. All these help you keep your emissions low.

It can even be healthy for your wallet. Since there are few moving parts and the system is sealed, very little could go wrong and your hydronic heater will stay maintenance free for many years. If you use quality components and ensure proper installation, the system is pretty much set-and-forget.

Brivis Ducted Gas Heaters Review

Date: Jul 10, 2018 - 7:56 am

Ducted gas heating is arguably the best method for keeping your home comfortably warm, especially if you’re living in regions with harsh winter season. It can provide central heating for the whole house whilst allowing you to heat individual zones only when needed.

There are lots of ducted heating brands to choose from, but one that quickly comes to mind is Brivis.

Now a Rinnai company, Brivis has been a household name among Kiwis for over 50 years. They have captured the market with world-class home heating systems tailored for New Zealand’s climate conditions.

The question is which Brivis heater suits your home? To help you make an informed decision, we will discuss here what you can expect from Brivis’ ducted gas heating solutions.

Brivis Ducted Gas Heaters

brivis_gas_ducted_heatingThe ducted gas heating system comprises a heating unit connected to a number of outlets via a system of ducts, which are strategically placed throughout your home and neatly tucked away in the floor or ceiling.

Some ranges such as the StarPro lets you add heating zones, which allows you to regulate the temperature one room at a time or to switch off heating in rooms that are not in use.

The StarPro 6’s Quatrra technology, combined with a 4-pass heat exchanger with a modulating gas valve, enables the unit to maintain a supply of warm air to the entire home using less gas. As the home heats up, the heating unit modulates the gas so only a minimal amount of energy is used to maintain the temperature level. Once the desired temperature level is reached, the heater switches off and the fan slowly comes to a halt to ensure all remaining heat inside the unit is utilised. This clever engineering is what makes it highly efficient and economical.

Among its other notable features are the:

  • Zero ChillTM soft fan that eliminates cold drafts on start-up
  • CustomairTM which adjusts air volume to better match airflow to your home – up to 16 fan speed settings
  • Cool TouchTM double sided and fully insulated cabinets that keeps heat where it is needed.

The other Brivis ranges also have superior benefits of their own.

StarPro 4 is the ideal option if you’re planning to upgrade your old ducted gas heater. It’s a universal internal/external unit with efficiency of up to 4.8 stars, making it a flexible and economic solution. The only drawback, perhaps, is it’s only compatible with natural gas unlike the StarPro 6 which compatible with universal LPG.

If you want a low-cost replacement, the two-piece Wombat range is one to consider. It’s designed to suit virtually all types of homes with external weatherproof units that deliver superior airflow at an economical rate.

Star Rating

The standard rating for efficiency is 3 Stars – any less is not worth looking into. The more stars, the higher the energy efficiency and the more economical the ducted gas heater is to run. On average, a 4-Star unit saves you 13% on energy bills; a 5-Star unit saves you 22%; and a 6-Star unit saves up to 30%.

Brivis offers some of the highest rating units in their respective classes:

  • Wombat series: 3.8 Stars
  • Buffalo series: 3 & 5 Stars
  • Compact Classic series: up to 3.5 Stars
  • Starpro Series: 4.8 & 6 Stars

StarPro 6 is one of the only two highest rated ducted gas heaters in the world.

brivis_gas_ducted_heating_systemsEnergy savings

Space heating eats up a big chunk of your household bills. If you’re looking for a way to maximise energy usage whilst maintaining comfort, zoning is the answer.

In particular, the StarPro 6 lets you conveniently heat up to four distinct zones. This enables you to manually adjust and control heat output for each of the different rooms.

Central heating systems are often designed to effectively heat up the entire home. However, in actual, you only ever use several rooms at a time, not all areas in your home. Having control over the temperature in individual rooms helps you cut your energy bills significantly.

Controls

Brivis offers a range of options for optimal temperature control. The Brivis Touch is simple and easy to use, giving you access to all features and functionality on one sleek interface. There’s a manual controller with the simplest thermostat controls as well as a programmable controller with both auto and manual modes.

Ducted heaters under 4 Star will function perfectly on manual type thermostats, while higher rated systems need an electronic controller.

With the Brivis NetworkerTM installed in each zone, you no longer have to rely on one central controller to manage the heat for your entire home. It’s convenient and simple.

The StarPro 6 ducted gas heaters have an upgrade option using the ICE system of cooling for extra temperature control in the room. This cooling system is placed onto the ducted heater and can be controlled using the same controls provided with the ducted heater.

Costs

Brivis units alone cost anywhere from $3,100 to $5,600 – a fair price if you think about the unit’s performance as well as the potential savings you will get. Expect this figure to go up to three times when you factor in the installation fees or if you want to add extra functionality or combine the heater with a central AC.

The total cost will also depend on the size of your home, the features you want, insulation and your home’s heating demand.

Installation

Many units are compact, splittable and weatherproof, allowing for easy all-round installation especially indoors and in small homes.

To achieve an optimised heating solution for your home, our specialists at Central Heating can custom design the duct layout and specify the appropriate zones for your Brivis ducted gas heater. We have experience in designing practical heating solutions for small dwellings through to large and complex installations. We also repair and service existing Brivis heaters to maintain optimal performance for years.

Once you try a ducted heating system, chances are you won’t ever want to go back. Talk to our Brivis specialists today to know more about it.

Schedule Radiant Central Heating Maintenance Before Winter Comes

Date: May 27, 2018 - 10:47 pm

Autumn is already giving way to winter as a wild dose of snowfalls and downpours started rocking the southern parts of New Zealand. It’s going to get brutally cold pretty soon with the early arrival of winter.

While we are having some briefly heavy rain showers here in Auckland, we’re still expecting weeks of cool, breezy weather ahead. It’s the best time to have your central heating system checked before you’ll rely on it most when the temperatures drop.

Ensure efficiency

Preparing your radiant heating system in advance not only ensures your comfort but also your home’s energy efficiency. You can save between 10 to 20% on your home heating bill just by ensuring the maximum efficiency of your system. Checking your heating system early in the warmer months also helps you know if there are issues that might require repairs.

Here at Euro Plumbing we see an increase in demand for heating repairs during wintry weather each year. Most people don’t prepare their homes adequately for the winter and find themselves beating the peak heating service rush. It makes sense to have maintenance checks and services completed as early as possible.

service_your_heater_before_winterSafety first

Anything that heats up can be a potential hazard. You’re dealing with hot water, high-pressure steam or gas, which can make troubleshooting dangerous. Ditch the DIY mentality and call a professional in to service your radiant heating system. Also, you don’t want to cause any damage to your flooring or heating equipment by attempting to do anything on your own.

The best you can do is to run your radiant heater on minimum setting in autumn, so you don’t shock the system when you put it on full blast during the winter season.

Annual servicing

This is something most homeowners think they can do without, but that’s not actually the case. Central Heating NZ will test your central heating system for efficiency and safety. This ensures your radiant panels are thoroughly clean and all components and controls work properly. Regular central heating servicing and maintenance also prolongs the life of your central heating system and keeps your warranty valid.

If you’re worried about the servicing cost, you can schedule annual maintenance in the months leading to winter so you’re not paying additional money for winter proofing your heating system.

Retrofitted central heating system

Radiant central heating is a safe and reliable heating option. If you don’t already have a system in your home, now is the perfect time to install one. Our systems can be fully retrofitted onto any typical Auckland home powered with gas, solar or heat pumps.

Because radiant panel heaters have the quickest response time and can be individually controlled for each room, having them in your home can result in cost and energy savings. From your heat source, we will discreetly install interconnecting piping that will link a series of panel heaters, providing your home a total heating solution.
