Heat pump consumption 2019 on a monthly basis

You can't see where you live, so where approximately, if you don't mind saying? How much does the srm cost for you, these costs should be factored in; at 20 times per year, that will probably amount to 200-300€ as well.

Oh, Leipzig. The fireplace is probably not that extreme. Roughly, it is on for about 3 hours, producing about 15-20 kWh of thermal energy. However, this cannot be completely deducted from the heat pump, as it raises the temperatures in the house to about 25°C. Very optimistically, I think it saves 5-10 kWh of supply temperature, which corresponds to about 1-2 kWh of electricity. 20 x 1.5 kWh x 26 cents equals 7.80€ savings per year.

Just read off: Exactly 2 years in the house, heat pump consumed 3250 kwh (hot water plus heating), meaning 1625 kwh per year. At our electricity price of €0.27/kwh, that amounts to about €36.5 per month. No heat pump tariff, because despite cheaper electricity price, it would be more expensive due to the additional meter.

Such consumption figures also show that it depends on usage behavior. Because many probably need that much just for hot water over the course of the year. So comparability is simply not given, but it is impressive what is possible.

@tego no children who bathe every 2-3 days?

With the ever-decreasing consumption, small changes in the environment or user behavior naturally have a strong impact on the balance. 180 vs 200 sqm is a significant difference, as are the year of construction, number of people and their hot water demand (bathing, Rainshower showers) and so on. Region, type of heat source, controlled living space ventilation, ...

It is really hard to compare.

Tego did not say anything about the insulation standard, house type, location, etc. Our children bathe almost daily and my wife showers until the tank is empty.. nevertheless it only takes "600" kWh of electricity for hot water. With 1000 kWh of electricity, you can keep a well-insulated timber-framed house warm.

In the first year with an air-to-water heat pump in northern Germany. 1400kWh electricity 7100kWh heat (of which about 15-20% for hot water for 2.5 people, rain shower)

The house has about 150m² without basement, insulation between KFW 55 and 40, central controlled ventilation. 10m² south-facing windows, 18m² west-facing windows, 2m² north-facing windows. No thermostats, no buffer tank. Room temperatures up to 21°, also in the bathroom. There we occasionally heat additionally with electric heating.

In the second year, consumption is likely to be slightly higher because I heat more during the day to manage without heating longer at night due to photovoltaics.

More important than the insulation is the heating behavior, the settings, and the planning of the heating surfaces.
