Request information View specificationsSystem planning
Start with the heat demand.
A heat pump is part of a complete water-based system. Heat loss, emitter temperatures, hot-water storage and the available electrical supply determine the right installation.
Installation matters
Designed around the water circuit.
Plan underfloor heating, suitable radiators and hot-water storage together. Keep the outdoor air path clear and allow access for servicing, drainage and frost protection.
