Absolute pleasure dealing with warmth.nz. They gave great advice on how to hook up our hot water heat pump to an existing buffer tank, and made this job very accessible to me. Their fittings are of the highest quality and they work very well for our setup. Thanks so much for your excellent service!

Warmth.nz supplies products

for hydronic underfloor heating using air-water heat pumps.

Four times the efficiency. Now most luxurious. Now least expensive.

This is the modern way of Underfloor Heating, or In-Slab Heating.  This system gives the same most luxurious comfort as the old direct electrical wired way.  But, at about one fourth the running cost.

Even undertile and undercarpet systems still run at that old efficiency of 1kW of heat energy for each 1kW of electrical energy.
Now modern air to water heat pumps generate about 4kW of heat energy for each 1kW of electrical energy.  That’s right, four times as much.  The heated hot water moves the energy very effectively to your floor slab.

This method will definitely give you the most comfortable heating for your new home.  And it will deliver it at the lowest cost of all.  Our hundreds of clients can tell you that.  We don’t know of any who would ever have their house heated another way.
