Infloor Heating / Central Heating / Aerothermal

Water-fed heated floors radiate warmth from the floor up as opposed to most other heating forms of heating that create a build up of heat at ceiling height. Radiant warmth heats the floor, the carpet, the furniture, the walls and you, rather than heating just the air.

Warm and Cool can pair your radiant floor with a fuel efficient diesel, wood, coal or wood pallet fueled boiler; or alternatively we can help you combine the advantages of radiant floors and the incredible economy of an Air to Water Aerothermal heat pump to receive unbeatable value for money.

HRV Ventilation

There has been strong promotion of HRV ventilation systems in New Zealand using "so-called" warm air from your roof-space. There is however a complete lack of evidence that roof-space positive pressure HRV ventilation systems provide any heat to homes in the South Island in winter. Ventilate instead with a balanced pressure, genuine heat recovery system. Don't be fooled by a high pressure sales pitch and get the facts from Warm and Cool first.
