Hello everyone,
I have been living in our KfW 70 house since September 2014 and now have a few questions about heating.
I have a Vitocal 300 air-to-water heat pump installed indoors in the basement.
There is also a 200L (53 gallons) hot water tank connected.
The underfloor heating covers about 130m² (1400 ft²).
The room temperature is set to 21 degrees Celsius (70°F). So far, there has been no night setback.
The heating curve settings are: slope 0.4 – level 0K.
The seasonal performance factor displayed is 4.3.
The domestic hot water temperature is 55 degrees Celsius (131°F).
During this period, I have used about 5000 kWh of electricity – which seems quite high to me.
Additionally, the compressor has already run for 3800 hours and has cycled 1800 times. Assuming a lifetime of 40,000 hours, that would amount to just about 10 years.
Is this normal? The electricity consumption and compressor operating hours seem relatively high to me.
Unfortunately, I am a complete beginner when it comes to heating and have relied entirely on my heating technician. Hopefully, I can find some answers here.
I was told it might be normal to heat more in the first year because the house is not fully dried yet (brick construction).
Thanks and best regards

How often do you have your refrigerator serviced?
The chimney sweep is probably unnecessary as well. In the end, all of this likely costs about the same, unless you have special circumstances, such as no gas line or something similar. It’s ultimately a matter of personal belief.

If the ongoing costs are about the same in the end, why would you choose to spend more upfront on a heat pump when you have the option? The initial investment costs have not been the same since 01.01.16; moreover, you overlook that by using an air-to-water heat pump as the heat generator, you effectively avoid the gas connection from an accounting perspective.
Even before that date, the purchase costs for a gas condensing boiler plus solar system were roughly comparable to those of an air-to-water heat pump—at least with many providers. This year, we are even going a step further and offer the ground source heat pump—excluding drilling—also at no additional cost.

Geothermal heat pump at no extra cost: That’s an amazing offer, really good. I hope people (customers) understand what’s actually being offered.
A properly selected and installed system can achieve a coefficient of performance (COP) of around 5, which is impressive. A friend of mine already has one.
Times are changing. I’m still glad to have the gas connection, as there will still be technical developments in that area over the next few years.
But now it’s 2016 – different circumstances, a new era is beginning. In houses, this clearly means that heat pumps will be used for heating.
Just look at how Mr. Musk and his (still niche car company) are shaking up the automotive world and will continue to do so. With a speed of change (SOC) that is breathtaking. While it’s only an approximate comparison, worldwide energy is clearly undergoing a fundamental change. Pure and simple.
