ᐅ Climate Protection Act of Schleswig-Holstein

Hello

I am currently facing a problem. Starting from July 1, 2022, the new Climate Protection Act comes into effect in Schleswig-Holstein. My house was built at the end of the 1960s and so far has only been insulated on the roof. At the moment, I have an oil heating system that is about 20 years old and could probably still run for another 5 to 10 years. After that, I planned to switch to gas. But this new law changes everything, as after July 1, I will not easily get approval for a gas heating system. It is also difficult to find information or options. The law states that 15% of the thermal energy must come from renewable sources. None of the options seem to work with my situation. Here is a list of the possibilities and the problems I see with each.

Gas heating with a supplier contract that includes a biomethane share / not possible because my domestic hot water supply is provided by an instantaneous water heater. In this case, the hot water supply must also come 15% from renewables.

Solar thermal / My roof is already fully covered with a photovoltaic system.

Heat pump / my insulation is too poor for this (although I do have an air conditioner in the bedroom that can also provide heating).

Additional pellet stove / I have a large pellet stove in the living room, but it must heat at least 30% of the total living area. This would mean I would have to remove doors between the living room and bedroom.

The domestic hot water supply with the instantaneous water heater is already the most sensible solution for me since I live alone and am often away for work. Therefore, the hot water consumption is very low and is also generated by the photovoltaic system.

Does anyone know another solution to meet the 15% requirement?

I would prefer not to have my heating system replaced in a rush. Also, I don’t even know how quickly the gas connection can be installed.

I appreciate any advice.

Regards

Sebastian

Since you don’t want to replace your current oil heating system right now—you mentioned you would replace it in 5 to 10 years—you still have 5 to 10 years to consider your options.

One concrete possibility is a gas heating system combined with a gas supply contract that includes biogas.

Otherwise, note that if implementation is not possible for technical or structural reasons, if it would require disproportionate effort, or if particularly valuable building fabric needs to be preserved, the obligation to comply can be waived.

So, Sebastian, take a deep breath and relax. It’s not as serious as it seems.

Thank you for your response. The problem is that if I install a gas heating system with a biogas contract in five years, I am required to also produce domestic hot water using the heating system. This would significantly increase the costs, in addition to the probably more expensive biogas. The question of what is disproportionate is also quite subjective.

This seems like the best starting point. You don’t necessarily have to install it on the roof; the facade often has space, or you can mount it on a raised structure on the flat roof of the garage. I’ve also seen systems installed on retaining walls. With a bit of creativity, you can definitely find a spot for solar thermal.

Thank you for the response. Solar thermal would be very difficult to implement. It is a rectangular hipped roof bungalow. The south side is fully covered with photovoltaic panels, the north side is shaded. The east and west sides are too small. The garage is at basement level and receives hardly any light. Wall mounting is also not possible due to the large windows. The only option would be to install something in the garden, but would that still be economically viable?

The pellet heating system would be an option
