Hello fellow home builders,
we have started constructing a single-family house. The approved building permit / planning permission includes a gas heating system, which we still want to install.
There are two possible scenarios:
1. What happens if the heating system is installed in October 2023, but the house is only inspected and approved in February 2024?
2. What happens if the heating system is installed in January 2024, and the house is inspected and approved in May 2024?
Both options are difficult to plan for. So far, we do not know whether the construction schedule might be delayed.
I haven't found any information on this. Do you have any further details?
Regards,

I would also check where the gas heating system is located and whether a heat pump could be easily installed there, considering space availability and the position within the house. The utility room is in the converted attic.

Hello,
to put it differently: Does the insulation standard and the heating installation allow for a future, straightforward upgrade to a heat pump? In other words, is there underfloor heating with reasonable spacing of the heating circuits, or are standard radiators still planned?
The insulation in a new build will definitely be sufficient, so the question is about the heating system design. Currently, the additional cost for a heat pump would probably be so high that you hardly recover the extra expense, even if the gas price doubles or triples. When the heating system needs replacing in 20 years, you can install a heat pump then, and that’s it.
A 135 m² (1450 sq ft) terraced house with solar thermal should manage with a maximum gas consumption of 8000 kWh per year. (That was our consumption in a 135 m² (1450 sq ft) semi-detached house built in 2011). That results in gas costs of 800–1000 € per year. A heat pump would cost about 700 € per year. Even if the gas price doubled while electricity prices stayed the same, that would mean maybe 1300 € extra annually. Currently, a heat pump would cost you about 20,000 € more upfront. You also need to factor in around 4% interest on that. This means a saving of about 500 € per year with the heat pump. That is an ROI of 40 years, which is longer than the heating system’s expected lifespan.
In other words: If the house can be properly converted to a heat pump later, I wouldn’t worry too much about it.
Best regards,
Andreas That’s exactly how I see it too! Gas heating lasts 15–20 years; who knows which technology will be trendy then.

xMisterDx19 May 2023 11:53Just got mail in the mailbox. The municipal utilities are reducing the gas price in basic supply from 20 to 11 cents per kilowatt-hour, and there are already some providers offering under 10 cents per kilowatt-hour with a 12-month fixed price.
This brings the ratio of electricity price to gas price back to about 3 to 3.5 to 1...
And an air-source heat pump is never economically viable because you won’t recover the additional cost of around 15,000 EUR (about $16,000), especially in existing buildings where it’s hard to achieve an annual performance factor (COP) above 3 due to high flow temperatures...
Yes, yes, CO2 pricing in 2027... don’t count on it just yet...

The electricity price is again below 30 cents, for heat pump electricity 26 cents. That is 2.6 times the cost compared to gas and makes sense purely from the consumption price, even for existing buildings. An additional cost of €15,000 (about $16,500) for a heat pump is just crazy, and whoever replaces in 2027 … well. It’s possible to do.
