We are planning a new build. The footprint of the house: 10 x 14.5 meters (33 x 48 feet). Ground floor: a household of two retirees. Upstairs, a self-contained apartment for one person.
Heating options / power supply:
a) standard gas boiler
b) ground source heat pump, electricity from the grid
c) ground source heat pump, electricity from own photovoltaic system and possibly battery storage
d) ground source heat pump, electricity from own photovoltaic system, battery storage, and possibly cloud services
So far, we have no information about the price difference between purchasing a standard gas boiler and a ground source heat pump.
Two construction companies said a standard, affordable gas heating system would be sufficient since houses today are so well insulated that the heating demand is not very high. But is that future-proof?
And if a heat pump is chosen, is it better to have electricity supplied from an own photovoltaic system? With or without storage? In addition, a cloud solution?

With a heat pump, this can be worthwhile if you want to. With gas, not so much.

That is possible, but not cost-effective. The same applies to gas, although to a lesser extent.
In my opinion, maintenance for heat pumps is a myth. The comparison with air conditioning systems is misleading. Air conditioning maintenance involves leak detection and disinfection. The latter is unnecessary for heat pumps, and the former is easily monitored. Of course, there are components subject to wear, such as the circulation pump, but those aren’t maintained—you either have functioning or broken parts.

With a heat pump, this can be worthwhile if you want to put in the effort. With gas, not so much. Of course, it is also worthwhile with a gas heating system. However, the effects are not as significant. But even a gas boiler will break down more quickly if it constantly cycles on and off due to incorrect or unsuitable settings, and savings are just as possible if less gas is needed by adjusting the heating curve and domestic hot water production to match consumption.

pffreestyler19 Dec 2019 09:22When I read this... I can't even set my Buderus 172-14 to a supply temperature below 30°C (86°F).
That’s not necessary. I don’t skimp on the temperatures. Everything is adjusted according to the outside temperature. In the bedroom, it’s constantly 19-20°C (66-68°F) no matter what. The living room, on the other hand, is usually around 24°C (75°F) thanks to sunlight. Still, I don’t want to pay more than needed. So the gas boiler is set to use only what is necessary. Nothing is being manually adjusted. The system regulates everything automatically.
And when the temperatures allow it, heating is not turned on at all. Just like now and since about yesterday noon. Only this morning the heating was on briefly due to hot water demand for showering. At the moment, the supply temperature is just under 23°C (73°F).
