Hello everyone,
We are about to start building our house soon (if everything goes smoothly, construction will begin in spring).
It will be a solid construction house of about 125 sqm (1,345 sq ft) with triple glazing, among other features. Also, it will have full underfloor heating.
We will be building without a basement. Our utility room is about 9 sqm (97 sq ft).
Now I am facing the big question of how to best heat the house.
The construction company recommended a propane tank in the garden, but I’m not comfortable with that option.
What other options do I have that won’t blow the budget?
What about an air source heat pump? I’ve read many good as well as bad reviews about them.
After reading so much, I’m feeling overwhelmed...
I would appreciate any advice 🙂
Thank you very much

Hello,
€uro is right. The actual demand must first be determined or calculated.
You can roughly estimate a general direction beforehand using various data.
How is your house insulated (final energy demand), where is it located (climate zone), how many people live there, and is there a gas connection?
For example, with a KFW70 house with only 125 sqm (1350 sq ft) of heated living area (underfloor heating), if there is no gas connection (otherwise why would you place or bury a tank in the garden?), and no basement – a properly sized air-source heat pump would generally be a suitable option. You wouldn’t need a chimney or flue pipe for a gas condensing boiler either. Or perhaps a small ground-source heat pump.
These are my ideas as a homeowner/builder (2011/12).
But even experts can only tell you more once the data is available.
Best regards

You can maybe roughly estimate a general direction in advance based on various data.
..The actual performance and energy demand can be calculated in advance with a tolerance of about 10...15% quite accurately, since all building data (the used or planned components), the building orientation on the construction site (building permit/planning permission documents!), the desired or intended room temperatures, and the required hot water demand are basically fixed. In connection with the intended technical system configuration, you get the expected consumption (kWh), and with the energy carrier price per kWh, the expected consumption costs.
Later consumption can be evaluated/assessed this way, and noticeable deviations can help detect errors easily.
Minor, temporary deviations generally do not affect the annual balance significantly. In addition, heating energy consumption is climate-adjusted annually.
Why homeowners sign contracts naively without understanding these correlations and go into significant debt for this is almost beyond me 😕
Usually, the “cat in the bag” is bought, and when the consumption costs turn out to be much higher than expected, there is complaining afterward and a desperate search for someone to blame! 🙁
Best regards
