Hybrid heat pump60% less gas — keep your boiler
Save up to 60% on your gas bill without replacing your central heating boiler. Net from €3,075 after ISDE subsidy.
How does a hybrid heat pump work?
A hybrid heat pump works alongside your existing central heating boiler. The heat pump does most of the heating work on mild days. When it gets very cold or you need hot tap water, the boiler kicks in automatically.
This combination delivers up to 60% gas savings without requiring a remodel of your heating system. You keep your existing radiators and boiler.
