ᐅ Is a Separate Meter and Electricity Tariff for an Air-to-Water Heat Pump Beneficial?

I’m just wondering how I can check how much energy the heat pump has used. I couldn’t find anything about this in the menu.

Which brings us back to the topic.
Have you taken a look at the user manual? What’s the model name of the "patient"?

Yes, but unfortunately I didn’t find anything. We have a Daikin Altherma 3 R ECH2O.

Check now what your average daily household consumption is. It will probably be somewhere around 10–14 kWh. In winter, due to heating operation, it often rises to 20–30 kWh, and for some even 50 kWh per day or more.
Simply calculate the difference from that, or have a separate meter installed for the heat pump.

How am I supposed to measure that? You can only do that if you connect a separate meter to the heat pump.

That is actually the simplest and ultimately the most accurate method. There are heat pumps that "measure" their electricity consumption, but they often overlook standby power or the pump’s electricity use. Ideally, you have a meter installed BEFORE the circuit breakers on the DIN rail. Of course, only if you are interested in tracking it...

What output power? It is available from 4 kW to 8 kW heating capacity – at full load it consumes between 800 watts and 1,600 watts per hour.
