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

I wouldn’t install anything if I know the clock is ticking. In the end, you end up paying more. The clock is also ticking for heat pumps because the current refrigerant contains PFAS. PFAS is set to be banned from 2027, after which repairs will no longer be possible.

In my opinion, the price mainly increases due to the installers. I don’t see the exaggerated prices in retail.
Wolf CHA0A7 – indoor and outdoor units with domestic hot water storage under 8k
Panasonic Aquarea LT-L indoor and outdoor units with domestic hot water storage under 7k
Vaillant Arotherm VWL 75/6 with domestic hot water storage around 8.5k
All of these are good devices based on the figures and, thanks to ready configurations, essentially plug and play for the installer.
I don’t see the point in planning a hybrid system for a building of this size. For the extra cost of the gas boiler, you could replace all radiators twice and simply avoid it altogether. Now, the big advantage—or disadvantage—is that there is currently no heating system in the building. Previously, there were individual gas heaters installed, one in each living room.
Therefore, everything needs to be replaced. Since we don’t want to remove the entire floor in the upper floor and attic, the idea was to switch to low-temperature radiators there, as these rooms will only be bedrooms.
I can’t say much about the three units at the moment, but the prices look very reasonable. The question is, will these prices be passed on to the customer accordingly?
Thanks for your responses; I will keep you updated on what ideas the energy consultant comes up with.

So everything has to be redone. Since we don’t want to remove the entire floor in the upper floor and attic, the idea was to use low-temperature radiators there, as these rooms will only be bedrooms. The most important factor is always the highest required temperature in the house. If the radiators (with or without fans) can heat the rooms to 35/30°C (95/86°F), there is no issue combining that with the ceiling heating on the ground floor.

The prices look very reasonable, but is that cost actually passed on to the customers? I’m telling you, the margin is kept by the installers. We have a plumbing/heating supplier who sells to both professionals and private customers. They also have an installer subsidiary that passes on prices 1:1. Their quotes are miles apart compared to the self-proclaimed premium installer in town.

That is simply incorrect.What exactly is incorrect about that? Heat pumps contain PFAS, both in components (seals and hoses) and in the refrigerant. Whether the refrigerant can be replaced and what disadvantages this might entail remains to be seen.Hello everyone,
I had an appointment with EEB, and the IFSP was presented. Then we received the cost estimate from EEB, who was also supposed to supervise the construction. All in all, they calculated 315,000 euros (about $340,000), and this amount is what they want to have available to carry out the renovation. In addition, 30,000 euros (about $32,000) for construction supervision.
A simple question: has anyone replaced their gas condensing boiler in the last two years and still feels satisfied with it?
I really want to be part of the whole transition in Germany, but who wants to or should pay for it?
I’m a bit unsure whether only the measures from the IFSP, costing 160,000 euros (about $172,000), should be implemented.
