ᐅ Considering a Gas Heating System for a New Build?

Hello!

We are planning to have a house built and are currently still in the initial planning phase. However, after a conversation with the architect, we are already considering heating options.

We are not building a KfW-certified house, but one strictly following the Energy Saving Ordinance. It will have about 220m² (2,368 sq ft) of living space plus a basement.

In various building specifications from contractors (we are having a turnkey build), we often see heat pumps that require an additional outdoor unit beside the system in the utility room. For aesthetic reasons, we are not very keen on that.

What alternatives are there for this kind of setup?

Gas heating combined with solar (the gas connection is available)?
Geothermal heat pumps?
Or other air-to-water heat pumps that do not require an outdoor unit?

We will probably have a hipped roof (with regard to solar panels). With a flat roof, the panels look quite unattractive.

About one day from 21 to 23.5°C (70 to 74°F).

Um... I actually meant the outdoor temperature... so what do you consider a significant temperature rise outside and for how long, since you mentioned that this would bother you because then the underfloor heating overheats your apartment.

For the price of one heat pump, you can get three gas boilers; whether you pay for gas or electricity is secondary, as both will become more expensive in the future.

There isn’t much more to say about this...

Oh, I didn’t note the outdoor temperature difference. Sorry.

From what I understand, Mycraft, you would use gas.

The outside temperature is the control variable in an outdoor temperature-controlled heating system...

So you really can’t know where the temperature increase in your current home is coming from; maybe everything there is just running on a fixed schedule.

In a house, it should actually be different... you can actively intervene in the heating system instead of just passively adjusting the ERR...

And yes, I would choose gas, or rather, I have...

With similar operating costs over a longer period but significantly lower investment, what else is there to consider?

Can I do that here as well? Our rental apartment in this two-family house has its own Nibe F750 heat pump. However, the installer said we shouldn’t tinker with it.

So you can’t do it after all…

Excellent installer. This is how it goes with every heating system: the installer sets it up to make sure it definitely gets warm. Your job then, in winter, is to find and adjust the correct heating curve. This is essential for an economical and comfortable operation.
