ᐅ Air-to-Water Heat Pump: Current Consumption and Data

So the 18 kWh are for heating and hot water? Then it performs similarly mediocre to mine when considering living area and average temperature. But it's also a Novelan, how could it be different. They are not efficiency miracles.

Correct, heating and hot water

It’s not performing that badly. Today, I saw in the Schwörerhaus group how poorly air-to-air heat pumps are running, with costs of 100 euros per month being normal for 140-150m2 (1500-1600 sq ft). But then there are some with extremely low values again. Or those who have combined it with photovoltaics, so the costs aren’t as noticeable.

True...photovoltaic system of 7.4 kWp on the roof

100 euros per month in January would be just about 13 kWh per day. Even looking at the whole year, that’s quite reasonable. That’s only 4650 kWh for heating and hot water. Nothing dramatic. You shouldn’t be misled by the total consumption figures of 4500 kWh.

I think he meant an average of 100 euros per month. There are quite a few who consume 8,000 kWh per year with a standard commissioning for an air-to-water heat pump.

In the past few days, I have used an average of 16 kWh. I actually find that quite good. But as I said, I want to carry out the hydraulic balancing as soon as it gets colder...

We’ll have the chance to do that in the south starting tomorrow. It will be really interesting, especially to see how slow the underfloor heating responds and how quickly the parallel shift of the heating curve works.
