Hello everyone,
We were incredibly lucky to purchase a great end-terrace house (heritage protection only on the exterior) in a fantastic neighborhood.
Built in 1915, but the structure is in excellent condition since it was built before the war.
No moisture in the basement, and the roof is dry.
Heating was provided by gas individual heaters in each room, but these have already been removed.
Living space is about 110 sqm (1,184 sq ft), garden area 450 sqm (4,844 sq ft) in the beautiful Palatinate region.
A gas connection is available.
We now want to renovate and already have an energy consultant who will also oversee the construction supervision.
Initial feedback from the energy consultant:
- Photovoltaic system on the south-facing roof without shading
- Thermal buffer storage recommended
- Ventilation system combined with an earth tube (seems to replace a split air conditioning unit? Does anyone have experience with this?)
- Ceiling heating
What I am considering:
- Photovoltaic system on the south-facing roof
- Thermal buffer storage
- 10 kWh electric storage battery
- Underfloor heating on the ground floor
- Low-temperature radiators on the upper and attic floors
- Split air conditioning units recessed into the ceiling in the living, bedroom, and guest rooms
We will fully equip the house with KNX automation, including modern and up-to-date control of the heat pump and storage system.
What would you suggest adding, combining, or improving here?
We are in a very comfortable financial situation, in our early 30s, and want to “do it right” this time.
The exterior of the property must be preserved, except for the photovoltaic system on the roof, as environmental protection takes priority over heritage preservation.
Thanks for your suggestions and information.
Best regards

Quick question since it fits the topic: Do you have a rough idea of how much a small photovoltaic system costs? I’m in a similar situation but have no clue which direction to go with a photovoltaic system.

With storage? If yes, how large?
I just commissioned a 5.2 kWp system with a 12.6 kWh storage and a 16 A wall charger for 16,000 euros.

Do you have a rough idea of how much a small photovoltaic system costs? As a large balcony power plant, you can buy such a system for well under €2,000 (e.g., 4,050 watts with a single-phase Growatt hybrid inverter for €1,600 plus mounting materials). Then you just need to have an electrician connect it or have it installed on the roof. Does it need to include a battery storage system?

As a large balcony power system Currently, balcony systems are allowed a maximum of 600-watt heat pump capacity. The change to 800-watt heat pumps, in my opinion, has not yet been approved.
Of course, I can buy the materials much cheaper. Installation on the roof and the certified electrician are not suitable for DIY. My strings reach over 400 volts.
