ᐅ Heat Pump – Is It Only Worthwhile with KfW55-Level Insulation?

We are planning to build with DEURA. By default, they use 36.5cm (14.4 inches) Poroton bricks without additional insulation on the exterior walls. The extra costs to meet the KfW55 standard are estimated at around 10,000€ (euros). To save money, and because KfW financing doesn’t offer us much benefit, we are considering skipping these additional measures.
Now to my question: do you think we are right to install a heat pump, or is it only worthwhile if the house is properly insulated to the KfW55 standard? Heat pumps are somewhat controversial, and I am considering switching to gas instead.

What options do you actually have if gas is not available, deep drilling is not permitted and wouldn’t make sense anyway? If near-surface geothermal energy is also not an option? Then the only choice left is the air-to-water heat pump...Also good – then you don’t have to choose [emoji6]Similar topics
