Industry Update

The winter time is the busy time for heating people! I am sure you are all flat out installing and servicing heating systems—we have noticed that in general it has been a busier year than the past two seasons.

From Invercargill to Northland projects are starting to happen, which means that the general public are confident in the future of central heating. We hope this lasts for a while, but that you all get a break at some stage also.

The group-home builders are also gearing up for the expected surge in new homes required. It’s a good time for heating installers to build relationships with these companies as we are finding that more and more people wanting a new home are looking for better comfort that central heating systems can provide.

We wish you all the best for the second half of the year!

New DeLonghi Radiator


DeLonghi have launched their new profile radiator, featuring a faster reaction time than standard radiators. In the PHD (Preferential Heat Distribution) radiator, the water flow is directed to the front panel first. This means the heat is radiated into the room 25% faster than a standard radiator, heating the room more quickly.

Of course, they still carry DeLonghi’s class leading 25-year warranty!



While our core products are radiators, underfloor heating products, gas and diesel boilers and hydronic heat pumps for the residential market, we are offering products from our same suppliers to the commercial market.

We stock a range of Baxi Gas Boilers up to 150kW, Firebird Diesel Boilers up to 100kW and Baxi Commercial Hot Water cylinders up to 1000 litres. Some of these products have gone into projects such as BP House in Wellington. Some installers do commercial as well as residential projects and we are able to assist with this.

Technical Tips

One of the trickier parts of central heating installations is the control. We often assist with this part by providing overview schematics as well as wiring diagrams. However, electricians are often asked to wire up systems without this assistance.

  • We find that it helps if you draw out a diagram of the system you are installing explaining how you want it to be controlled and then the electricians have a better understanding of what is supposed to happen. 90% of the aftersales service calls we receive are controls related.
  • Electricians who do industrial work are often very familiar with controls and can often do quicker electrical work for central heating installations.
  • Fit a kilowatt/hour meter to all heat pump installations. This ensures that the customer can get the real story about how much the heating system costs to run!
