Heat pumps are the future of heating and water heating not just in the USA but around the world. Heat pumps, through the near-magic of a carefully designed refrigerant circuit, transfer heat rather than creating heat through combustion or electrical resistance. In doing so, heat pumps achieve efficiencies and “coefficients of performance” between 250% and 500%. Air-to-water heat pumps, like Stiebel Eltron’s WPL monobloc heat pump can provide super high…
