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.

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.

Don’t wait until winter’s already in full blast. Get your home’s central heating system serviced today. Call us for inquiries!

If you are looking to install or upgrade your central heating, no doubt you want the most bang for your buck. This means that you will need to consider what is the best option for your installation and your needs. There are various systems types to choose from and knowing the benefits of each can mean the difference between a system that costs your more money to run and one that saves you money.

Types Of Systems

Central heating systems can come in a number of types, but all broadly fall into one of the following categories:

  • Wet systems – involving a boiler or heat exchanger and radiators
  • Warm air systems
  • Storage heaters

wet_central_heating_systemWet Systems
Wet systems work by circulating hot water through a system of pipes that connect the radiators throughout the house. A boiler, the center of the system, burns a fuel such as LPG to heat the water. Sometimes there is a heat exchanger and this heats the water instead of the boiler. It is also possible that a hot water cylinder is connected to this system. This type of system is the most popular type of heating system in the UK.

The boilers can use a selection of fuels to heat the water, The most common are natural gas and LPG, with some using heating oil. Rare instances use coal but these days these systems are uncommon. Electric central heating boilers are also another popular option.

The radiators, despite their name, don’t actually give off radiant heat, but rather deliver most of their heat through convection. Air warmed by the radiator usually rises and cooler air falls relative to it, resulting in warm air circulating within the room or space being heated.

5_HVAC unitWarm Air Systems
Warm air systems heat air by a boiler, usually fueled by gas such as LPG or natural gas, and are fed by means of ducts doing to rooms around the home. The warm air enters the room through a wall or floor vent. These systems are particularly popular in North America and are also commonly used in many commercial buildings, however mostly serve as cooling systems (air conditioning). For residential buildings and homes, wet systems have generally replaced these types of systems.

Storage Heater Systems

storage_heater_systemsStorage heaters work by heating water overnight during off-peak electricity hours, then release the heat gradually during the following day. The storage heater will normally have at least two controls, one for controlling how much electricity is used which will determine how much heat is generated for storage, and another for controlling how much heat is released. This means that you can set it to release the heat when you need it, so if you are out during the day, you are not wasting heat when you are not there. More advanced systems also have thermostatic controls. In some cases, storage heaters can also serve as direct electric heaters, providing heat directly from electricity without going through the storage stage.

So now that you know about the different types of systems, what are the costs?

Storage heater systems are almost always more expensive to run than an equivalent wet heater system. They are really only best used if you have no access to gas supply or if you are on solar and have excess electricity that won’t cost you to use. The advantage of a storage heater system is the installation cost and hassle is a lot less than the wet systems.

Wet systems that run on gas will typically cost more to install, however you can save up to 50% or more on operating costs with an efficient gas heating system when compared to other central heating systems. One thing to bear in mind is gas systems do need regular servicing to keep them in 100% operating condition, so factor this into your yearly operating cost.

Cost And Custom Blamed For Lack Of Central Heating In NZ Homes

Date: May 29, 2017 - 8:50 pm

Everyone loves traditions. They can signify a belief or behaviour with its roots steeped in history of years or people long gone but not forgotten. Unfortunately, one such tradition in New Zealand is leaving around 95% of our population living in cold, draughty homes and suffering from a slew of health related problems. What tradition is this? The one of viewing household heating as a luxury and only heating one room at a time.

If you have grown up in New Zealand or in fact, spent any decent length of time in a New Zealand home built in the 80’s or earlier you will have experienced being indoors with all doors and windows closed in the middle of winter and still feeling a draught around your ankles or shivering as everyone huddles around a heater.

Kiwis are a strong resilient people but sometimes traditions need to be broken. No longer do we have to sit huddled in the lounge everyone trying to get a portion of the heat from a single heat source – be it an open fire, a gas heater or an oil fin heater.


Central heating has long been established in Europe and Canada as being the best form of home heating. Because people and governments have seen the positive impact of having people live in warm, insulated homes the cost of installing central heating has reduced dramatically in these colder climates and it is a given that a home will provide an ambient all year round temperature.

New Zealand on the other hand often has a misconception about it that our temperatures are sub-tropical and we don’t have a need for central heating. The truth is though, that still a large proportion of our homes are not air tight and still remain with poor and inadequate insulation.

We can no longer rely on chopping the nearest tree down to provide fuel for a winter fire as many cities and regions in New Zealand have either phased out open fire places or are in the process of doing so.

What seems to be missing from the New Zealand market is a central heating system that is affordable for the average homeowner, and that is specifically designed with New Zealand’s temperatures and families in mind.

The reality currently faced by many who would like to have central heating in their homes is that they simply cannot afford the $8000 and $15,000 it requires for a central heating system to be purchased and installed to heat their homes.

CCentral_heating_in_new_zealandentral heating has the ability to provide heating throughout your entire home. It is not limited to just heating one area. Because all central heating systems come with a thermostat and a timer the control and convenience is all yours. You can set the system to turn on at set times and to turn off or reduce its use when the family is outside the home following other pursuits like work, school or recreation. Many central heating systems now come with zone control which allows you to control the ambient temperature for certain parts of your home.

What is gaining popularity within New Zealand is the installation of heat pumps. Unless temperatures drop below zero (which can happen but not very often) heat pumps are an energy efficient and economically viable option to keeping your home warm and your family healthy.

If you are worried about your families health and comfort for this coming winter – give one of our consultants at Central Heating a call today. We can arrange a site visit to your home and discuss the options available for your home and area and explain how our products can let your family enjoy winter again in your home. If health issues are paramount in your family – perhaps asthma is a winter nightmare for you or your children then do not hesitate to make contact. With a range of systems and a wealth of experience behind our knowledge Central Heating can custom design a home heating package for you that will fit your budget and your lifestyle.


Be Prepared Winter 2017 Is Coming!

Date: Mar 20, 2017 - 9:06 pm

Summer was more than a tad strange this year! While there were places in New Zealand that basked in the long drawn out hot days of a traditional summer, most of us were left wondering if it would ever truly arrive, and when it did show up for 2 or 3 days at a time, just how long it was going to stay around.

The days are certainly starting to cool off and with the change of Daylight Savings just around the corner, winter is apparent.

Assuming winter won’t come with the same nonchalance that summer did, winter in New Zealand is long, cold, and most definitely wet!


Is your home up to the task of keeping your family warm and healthy during this bleak season? Not only is warmth necessary for a happy family but many places in New Zealand suffer from dampness and the associated growth of mould and mildew.

The beginning of autumn, which is where we currently are, is a great time to consider how you are going to heat your home this winter and by what means. Growing up, we used to all huddle around a single heater that was based in the lounge, or if we were lucky mum or dad would start and then stoke the open fire so that the whole home would feel warm (unless you were one of the unlucky ones with their bedroom at the back of the house!).

In 2017 your heating options are many and varied.  Central heating is becoming more and more popular as a way of keeping your home warm and dry, therefore damp free. It is no longer something only considered by the rich and famous.

Central heating systems warm every room evenly so that the four-seasons-in-one-day weather stays outside, not inside. If you’re looking for a clean, efficient heating system with reasonable running costs, central heating is your answer.

Central heating can be achieved in a number of ways. We can provide you gas, diesel, heat pumps, radiator heating and underfloor heating options.

No matter the size of your home, big or small, or the size of your budget, we can get your home feeling roasty-toasty before winter.

Just imagine coming home from a day out and about to a home that is temperate. No longer do you need to keep extra layers and thick socks and slippers on. You can pad about your home in ultimate comfort.

Don’t let winter 2017 creep up and take you by surprise. Be like a boy scout and be prepared! If you have dismissed central heating before, maybe 2017 is the year you investigate it properly and make comfort a way of life for you and your family.

Central heating gone smart

Date: Sep 22, 2016 - 12:28 am

Central heating systems over the years have moved with the times, form the first systems used by the romans to modern condensing technology. Steadily moving with advances in technology offering users extra levels of comfort and control.


So what’s next in the world of comfort heating?

These days the majority of us use a Smart phone on a regular basis whether we order a taxi or a pizza. We expect a sleek modern approach from services and goods. Now the central heating companies have moved with the times offering app controlled heating control at your fingertips.

Offering the ultimate in control with intuitive user control and smart design App control will become the norm.

With rising fuel prices globally managing your consumption is as important as ever. Controlling room temperature and time settings enable the consumer to have a real effect on usage.

Additional benefits from using smart phone technology is the ability to analyse weather real time which adjusts the Heating to suit conditions in real time. Coming in for a cold snap don’t worry the app takes care of it. Keeping the home warm and comfortable without the need for intervention.  Alternatively, if you have a nice sunny home, when the suns out in the winter and the house is warm the heating app will switch off or down to save you money.

With many companies getting in on the heating technology revolution Smart heating is now a realistic affordable option for most heating solutions.

Having the added benefit of “controlling your home heating anyway” no longer will you have to worry about leaving the heating on when you leave the house. Many systems offer a Geo caching option which tracks your movements and builds a heating profile based on your habits. Making sure you only use heating when you need it. Leave the house every day at approximately 7.30 am the system will learn to turn it off at 7am using you less energy. Stuck in traffic on the home commute the system will wait until your near home.

Older style heating control programmers and thermostats are often confusing to set up and use. sometimes needing a heating specialist to set up, which can lead to additional cost when times and settings need changing. Today’s Smart phone apps are designed with this in mind offering users of all levels the ability to control their heating to the degree they are comfortable with, young old Tech Geek or technophobe, Modern Smart phone apps get over this hurdle with their ease of use and one tap design.

With a flurry of new systems on the market there is a heating controlled app system for all types home.

Systems like Honeywell EVO offer Smart heating control with the addition of individual Thermostatic Radiator Valve control taking smart heating control to the next level, offering 12 Zone control from a centralized control panel giving home temperature control like no other.

Smart Heating controllers can be fitted as part of a new full central heating solution or as a “retro fit option” bringing older systems into the now.

System Like TADO offer the consumer greater flexibility of which styles of System they wish to control. Coupling systems together to control Heating as well as Cooling systems. Giving the home complete flexibility and comfort when it comes to Temperature control. Keeping you warm or cool as you need.

Smart App Heating control has had an unexpected advantage.

Particular vulnerable people who live alone often with an illness or disability. Relatives or careers are able to monitor heat within the home ensuring their loved ones stay warm or cool.

A success story of this technology improving lives, was that of an elderly couple who both suffered from Alzheimer’s. who would regularly turn off their heating and not realize, their son who lived on the other end of the country. would need to travel sometimes over night to ensure his parents kept warm. The addition of a smart heating controller alleviated a stressful situation enabling the son to monitor his parents’ home with complete peace of mind.

Not just for the tech Savvy among us Smart controlled app Heating isn’t a solution for the future but is a solution for now. Controlling your heating this way will become standard with this generation expecting a better experience and level of comfort not see in past generations.

Got your central heating terminology right?

Date: Jul 21, 2016 - 11:50 pm

You suddenly feel the cold snip one morning and decide.. “I want central heating”. Next thing you do is go to your preferred search engine and start searching for a central heating installer or supplier.

The results are overwhelming and most likely not what you were actually looking for.

In principal searching the term “Central Heating” is a good idea, the only problem though, is that not many companies actually specialise in all forms of central heating.

So let’s try to clarify what’s what and differentiate some of these systems readily available in New Zealand.

The term Central Heating itself is a noun and in general refers to one system that is designed to heat a whole house or building. So to clarify, a heat pump or air conditioning unit is not a central heating system because such units are only designed to heat the room or space they are actually installed in.

To classify as a central heating system all areas need to be heated by the same heat source.

So what types of central heating systems is there in New Zealand?


Auckland being the largest city in New Zealand, offers the largest selection of central heating.

Some of which include:

  • Ducted Central Heating systems, these systems transfer heat by mass motion of air via a ducting system.
    Available heat sources included: Gas powered and electrical. Ducted Central Heating can be retrofitted into most existing homes.
  • Electric Underfloor Heating, (also called under-tile heating) is typically installed in smaller areas such as bathrooms or kitchens. Low profile pre-formed cable mats or cables can be installed under tiles, carpets or wood. In most cases electric underfloor heating is not a desirable total home heating solution due to electrical running costs.
  • Hydronic Underfloor Heating, is strongly recommended when building new. The cost to install the pipework into the concrete slab is a fraction of the ROI. These systems can be powered with gas boilers, heatpumps, solar, electricity, wood or thermal energy. Pex pipe is installed above the building mesh (in some cases below) before the concrete is laid. The energy source will heat water which will then circulate in the pipe generating radiant central heating energy. This system will maintain an even spread of heat throughout the home without drafts and is easy to control and manage. Underfloor heating systems are low temperature systems.
  • Hydronic Radiator Heating, works the same way as underfloor heating with the difference that you have good looking radiators on the wall (typically positioned under windows) instead of pipes in the concrete slab. A Radiator may vary from steel to slick aluminium and comes in many sizes to suit any situation. Radiator heating can be retro-fitted into existing homes and is currently the most popular form of heating in the Auckland areas due its low installation and running costs. Radiator hydronic heating is the most popular form of heating in Europe and the UK.
    Radiator systems are high temperature systems and cannot be run with heat pumps.

Selecting the one of above systems will fully depend on whether you are building new or not, your circumstances, expectations, site conditions and availability of energy sources. This could be Gas, diesel, wood, solar, wetback or even thermal energy.

Why not speak to the professionals about a key turn solution tailored to your needs.
