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

During the Advent season, 10 candles produce as much light as 200–400W,
so you can save a lot of electricity,
and the atmosphere improves.

So, the heating has been on since yesterday. I really hope that the current high consumption is because the screed is still cold and everything needs to warm up first.

However, the household consumption during this time was not very representative either. My wife used everything possible multiple times—washing machine, dryer, oven, stove, and so on.

Yesterday, on the first day, we had about 28 kWh, including household electricity. Over the last two weeks, the consumption without heating was about 13 kWh. If the heat pump uses 10 kWh in three days, then that would be okay. Let's see.

10 kWh for heating would be very low with the current temperatures. We are currently around 20 kWh daily.

10 kWh including hot water would be very, very low.

In December, we average 16.31 kWh per day.

Here is another energy consumption update:

The December forecast is currently at 700 kWh. Unfortunately, temperatures have dropped significantly; we now consistently have daytime temperatures between -2 and -5°C (28 to 23°F), with nighttime temperatures a few degrees lower. My wife bathes like a queen, and the kids shower every day, which impacts my efforts to optimize electricity use—so we are currently heating water about three times a day 😀. This really adds up at these temperatures.

Nevertheless, despite a significantly colder December compared to last year (2019 had an average temperature of 2.8°C (37°F), this year it is 2°C (36°F)), there is a saving of over 10%. I had hoped for a bit more, since consumption in the summer months was about 40% below last year.

How often does the hot water storage tank refill for you?

I’m not sure what you mean, but as mentioned, the tank is refilled three times a day because the temperature drops from 48°C (118°F) to below 42°C (108°F). The buffer tank has a capacity of 200 liters (53 gallons).
