ᐅ Preparation for photovoltaic or solar thermal systems with an air-to-water heat pump

Hello everyone!

Our construction will start in January (at least if the weather cooperates), and we have not planned for solar thermal or a photovoltaic system. Heating will be provided by an air-to-water heat pump from StiebelEltron.

Now, I would like to prepare for the possible retrofit of one of these systems. Our builder also offered us a solar thermal preparation. This includes two pipes from the utility room up to the attic, including insulation and sensor cables. It is supposed to cost €1,160.

Now I am wondering if a photovoltaic system might make more sense with an air-to-water heat pump?!

So, this is only about preparation!

The question is, what would need to be prepared for a photovoltaic system?

For your information: The offered solar thermal preparation would be routed through one of the wastewater ventilation stacks.

Could you give me some advice on this?

If a heat pump is used as the heat source, I would always choose a photovoltaic system instead of a solar thermal system.

Exactly. A solar thermal system requires a correspondingly large storage tank, which you generally don’t want with a heat pump and would also be inefficient. Directly using photovoltaic electricity for heating is also not sensible because it is uneconomical when a heat pump can convert 1 kWh of electricity into 2–4 kWh of heat.

Just install conduit pipes for the photovoltaic system and that’s it. Forget the solar thermal system.
