The most efficient way to heat a home. The Viessmann Vitocal 200-G is a ground-source (brine-to-water) heat pump — the technology with the highest year-round efficiency, delivering COP up to 5.0 by drawing stable heat from the ground.
Why it stands out
Because ground temperature barely changes, a geothermal system keeps a high COP in every season — the lowest running costs of any heating technology, and a premium German-engineered unit built to last decades. Ideal for new builds and larger properties with the space for boreholes or horizontal loops.
