HEATING SYSTEMS
Before investing in a heating system make sure your house is well insulated. A dollar spent on insulation is better than a dollar spent on heating as any heating system will be expensive to run if you have a poorly insulated or draughty house.
New Zealand lags behind the 8-ball as far as Central Heating is concerned, and many homes in the Southern Lakes area (particularly those built at a time when it was mainly a summer holiday destination) are heated unevenly and poorly insulated.
The World Health Organisation recommends your home should be heated to the temperatures shown.
If you want the full-home comfort of central heating for your new build, or the more budget friendly option of single room heating, we’ve explained it all here.

Central Heating refers to heating systems which distribute heat evenly throughout an area, as opposed to a single heat point like a fire or stand-alone heatpump.
Central Heating systems provide the ultimate in heating comfort with whole-house heating. They are convenient (easily controlled with thermostats and timers), and can be zone-controlled allowing you to heat different rooms to different temperatures.
Central heating systems are made up of a fuel source and either radiators, underfloor heating, or both.

Fire & Wetback Sytems
Nothing beats the comfort and mood of a classic fire. That’s if you’re keen on going out in the cold to get the wood!
Woodburners are reasonably energy efficient and if you have access to free firewood your running costs are virtually nil. Still very popular and of course can be teamed with a heat transfer kit also, which TaylorMade Plumbing can supply and install.
Woodburners have the added benefit of adding a wetback system to help save hot water heating costs (but this can take the heat away from your space heating).
If you’re in Arrowtown approved new woodburners must have an emission discharge rating of less than 0.7g/kg, and remember you’ll need building consent.
Radiators or Underfloor Heating?
There are two common ways of transferring the heat through your home with central heating: radiators and underfloor heating (both can exist in the same home).
The best option for your home depends upon your lifestyle, budget and the heat source that you are using. It’s really up to your preference.
The key differences are set out in the table below.
Choosing Your Fuel Source
There are three main options when it comes to choosing a fuel source for your central heating system.
AIR TO WATER HEATPUMP
Unlike the common air-to-air heat pumps which circulate hot and/or cool air through a single room, air-to-water heat pumps (and geothermal heat pumps) supply warmth to the entire house via water through a pipe network. They are highly efficient and easy to use.
Air to water heat pumps are most commonly used in conjunction with underfloor pipes, but the recent addition of high temperature hot water heat pumps means these units can now also be used with radiators – although these are more expensive to run.
Hot water heat pumps are very compact in size and can be fitted in any place. They can be used for heating purposes, as well as for the production of domestic hot water, or for both functions at the same time. The key here though is once on, keep it on – letting the water cool down can take up a lot energy (ie money) to heat back up.
DIESEL BOILER
The diesel boiler heat source heats either or both of radiators and underfloor systems. Diesel boilers are a cost-efficient heating option for many homeowners because they are very energy efficient and have relatively low running costs, ranging from 14.8-16.5¢/kW depending on the boiler, the current cost of diesel and the location of the home.
The boiler itself is usually placed in a garage or similar. You will need to have a diesel tank installed, which requires QLDC consent. QLDC also require that a bund is added to the tank. We are happy to take care of the consent process on your behalf if required.
It’s important to get your diesel boiler serviced annually. We often have customers who call us to get their boiler serviced and if it hasn’t been done for a few years it can be both dangerous and expensive. It’s safer and cheaper to book in an annual service with us to make sure your diesel boiler is running efficiently.
GAS BOILER
Gas boilers provide heat for radiator and underfloor systems equally well and can use either LPG or Natural Gas. This makes gas central heating a flexible option when determining which heating method is right for you.
These systems are very popular and affordable in the North Island where the cost of reticulated Natural Gas is low making the cost per kWh the lowest next to geothermal heatpumps (at a quarter of the capital cost though). The cost & availability of mainly LPG bottled gas supplies in the Southern Lakes makes them more expensive to run than a diesel option. They are, however, cheaper to install and a smaller (and probably better looking) boiler unit.
If you have a gas boiler for your under-floor heating and wonder why it’s using a lot of gas see our Tips & Advice page.
Both diesel and gas boilers are virtually silent to run.
