Hello
We have only been using the pump for 4 months (new build). At the moment, we find that with an indoor temperature of 25°C (77°F), it is pleasantly warm. Do you really save much electricity by lowering it to 23°C (73°F) or 22°C (72°F)? Or does it not make much difference whether it is 25°C (77°F) or 22°C (72°F)?
We keep it constant at one temperature setting.
Thank you

Well, now that you know what you want to do, everything is settled The fact that I’m not convinced by the idea of “just get started and see where you are in 10 years” unfortunately does not mean that I know what I want to do. It’s not that simple.

My skepticism about the approach of "first gas, then see what happens in 10 years" unfortunately does not mean that I know exactly what I want to do. It’s not that simple. It has all been said before: make a decision based on the heating load calculation. There are many posts already discussing the pros and cons of air-source and ground-source heat pumps—just do a bit of research.

There is always talk about heat pumps here. But as far as I understand, there are different types of heat pump systems.
Does anyone here have an exhaust air heat pump?I don’t have one myself, but from what you can read in many problem reports on specialized forums, the house should be at least KFW55 standard or better for this system to work satisfactorily and cost-effectively...
Thanks for the tip. I still have quite a bit to read and don’t have a clear overview yet.
Heating load calculation certainly isn’t everything.
First, there’s the basic question of which technology to choose: oil, gas, or heat pump.
Then, what type of heat pump: air-source, ground-source, deep geothermal, etc.
If you go with air-source, there are probably again budget, standard, and premium options, all of which would fit the heating load calculation. Surely there’s more than one manufacturer and model. However, in the initial overviews from suppliers, it only mentions air-source heat pumps, and as is often the case, the advertised price most likely refers to the cheapest model. Just like houses shown with brick facades in pictures often come with the note that the price applies to a plastered facade.
And maybe there is something comparable to certain models from Skoda, VW, and Audi. They all offer roughly the same, but prices vary greatly depending on brand image and target market.
Finding the right option is certainly not easy.

Why isn't this the case with air-to-water heat pumps? After all, they draw air from outside.

They also draw air from outside.In an air-to-water heat pump, the medium for energy transfer is not the air but the water or brine solution in the underfloor heating system. Here, heat transfer is more efficient than with air...
