FAQs
Are exhaust air heat exchangers eligible?
No they are not, because they are classified as renewable energy under the EU Renewable Energy Directive.
Chapter 4 of the government's RHI announcement says
Exhaust air heat pumps
Exhaust air heat pumps use air extracted from inside the building, for example from kitchens or computer server rooms, as their air source. They are particularly useful in very well insulated buildings which require mechanical ventilation. However, they are not classified as renewable under the RED as they do not rely solely on outside air and therefore will not be eligible for the RHI.
