Vertical Heat Pump Boiler

A heat pump supplies water at a lower temperature than a boiler. To heat domestic water quickly, the cylinder needs a heat exchanger with a large contact surface. That is what the vertical cylinders in this category have: coils designed for heat pumps, so the heat pump runs for fewer hours and works efficiently.

• With one heat exchanger: heat pump and electric immersion heater.
• With two heat exchangers: a second source is added, such as solar collectors or a boiler.
