how is an energy performance certificate for a house with a heat pump prepared? I see two issues here:
- How is the electricity consumption of the heat pump determined if it does not have its own electricity meter?
- A flat-rate deduction of 20 kWh/m²a (6.3 Btu/ft² per year) for domestic hot water production: negative values could easily result from this, especially with low hot water use combined with low heating demand. But even positive values are likely to be generally too low. How is this issue addressed?
Thanks and best regards from

Wow. That's quite a statement. By the way, I keep seeing endless real estate listings with heat pumps and energy performance certificates. Is it common for heat pumps to have their own electricity meter?Yes, that is now normal. These are simple meters that usually measure the electricity used by the heat pump and the energy it produces. My numbers roughly match up as well (I also don’t have separate sub-meters or heat meters).Of course, you can have a simple meter installed later on at the breaker panel. But that will only help you after a few years, since the energy performance certificate requires consumption data for three years.
