Class1

Integrated heat-recovery and heat-pump system.

When the heating energy demand for individually heated homes is reduced to the ultra low-energy level which will be the case for the Class 1 buildings a traditional hydronic heating system is no longer a viable solution. As explained above the distribution systemís installation costs and losses especially for sparsely located single family houses. Electricity and a heat recovery system for ventilation air are installed anyway in an ultra low-energy building. It is therefore an almost obvious solution to combine heating by heat pump(s) with the heat-recovery system and use the mechanical ventilation system to distribute the heat. These systems do exist, but it is the objective of the Class 1 project to develop this solution further towards a truly cost-efficient solution.

The development is documented in a report from the manufacturer – the document can be downloaded here.
