ᐅ Heating System for New Single-Family Home: Air-to-Air or Air-to-Water?

Hello everyone,

I am new to the forum and would like to get some information about heating systems.

We will probably start building our house in 2020. Now the question of which heating system to choose has come up.

There is no gas connection on the property, but everything else is available.

I did some research, and gas is no longer an option for me.

Now I am wondering whether to install an air-to-air heat pump or an air-to-water heat pump.
Ground source heat pumps are not an option due to drilling costs and the permitting process.

I currently have a photovoltaic system with almost 9 kWp capacity (built in 11/2019) on my outbuilding, which will be transferred to the new house.

What are your personal opinions on air-to-air versus air-to-water heat pumps?

Best regards,

How should one comment on that?
What is your heating load?
How large is the plot of land?

Are you planning to build a passive house?

@Daniel-Sp
I have no idea how to comment on this, that’s why I’m asking you all.
I can’t give you the heating load yet. The preliminary offer for the house is still pending. It will be a city villa with exterior dimensions of 9.00 m * 9.50 m (29.5 ft * 31.2 ft).
The plot is 1100 sqm (11,840 sq ft) with our current house on it, as well as an outbuilding with a garage, storage room, and warehouse.

@nordanney
It will definitely be a solid/concrete house. But I don’t know yet if it will be a passive house.

The most affordable option is air-to-air, but it is also the least efficient ....

What exactly does “everything else” include? Oil pipeline? District heating?

You can’t look at these factors separately; they must be considered as part of the overall concept. But do read up on the updated subsidies... for a 1100 sqm (about 0.27 acres) plot... vertical loop ground collector. Even if you don’t contribute any labor yourself, depending on the setup, you might actually come out better than with many other options once you take subsidies into account.

First, do some research and think about your goals (insulation standard, etc.). Then you should get a quote.

You wouldn’t just walk into a car dealership and say, “Make me an offer for a car 2.5 m x 4.7 m (8.2 ft x 15.4 ft)” and then register in a car forum to ask whether it should be gasoline or diesel based on those specs.
