OUR SYSTEMS
An air-to-water heat pump runs your hydronic system on electricity alone — no gas connection, no flue, and several units of heat for every unit of power it uses.
A heat pump pulls warmth out of the outside air and moves it into the water your radiators and floors run on. We install two ranges: Stiebel Eltron, engineered in Germany, and Heatrite EVI units.
01
No gas connection — runs on electricity alone.
02
COP up to 5.09: around five units of heat per unit of electricity.
03
Runs radiator panels at up to 65°C, as well as slab and screed floors.
