Central Heating New Zealand offer a free engineered design service to create a system suitable to provide even, radiant heating to the whole home:

• Residential — single storey, multi-storey, standalone or apartment dwellings
• Variocomp panels sit on top of the substrate 
• Suitable for all climate zones — minimum outdoor air temperature: -20°
• Ideal for open plan designs or designs featuring a lot of glazing
• Can be integrated with solar power systems

• Requires increased floor insulation values compared to an un-heated floor, refer to H1/AS1
• Floor coverings should be selected so that they offer the minimum resistance to the upward flow of heat
• Limited cooling performance (design required)

• H1 energy efficiency — systems are designed to be efficient in their operation and the insulation required for heated elements as listed in AS1 must be achieved
• B2 Durability — BRANZ Appraised. Multitubo primary pipes have a life expectancy in excess of 50 years
• G12 — The underfloor Multitubo primary piping system has been appraised for use as the piping components for water supply as per the scope of New Zealand Building Code (NZBC) Acceptable Solution G12/AS1, and verification method G12/VM1 and as pipe for proprietary heating systems subject to specific design.

Central Heating New Zealand has been installing hydronic heating systems in over 15,000 residential and commercial projects throughout New Zealand over the last 23 years.

Chofu heat pumps have been in use in New Zealand since 2014.

• Chofu are the first of its kind to use R32 refrigerant in New Zealand, which has than half the GWP (global warming potential) of R410A
• R32 efficiently conveys heat it requires less refrigerant volume per kW. This equates to a 10% reduction in energy consumption 
• The R32 Chofu boasts heating efficiencies over a COP of 4.5 and delivers water temperatures up to 60°C at high efficiency
• Chofu heat pumps patented anti-frost technology ensures high performance is maintained in temperatures as low as -20°C
