Hello,

I’m new here and hope this is the right thread to ask my question. :-)

My partner and I are buying a house (built in 1998). However, it only has a night storage heater installed.

So, my question is: what would be the best option for us?
We don’t have a basement, so an oil heating system is not possible. Underfloor heating is also out of the question. Heating with wood or briquettes is not an option either.

So, I guess a gas heating system is the way to go?

A friend told me that there might be subsidies available for the night storage heater if we install a solar system on the roof. Does anyone know anything about this?

Thank you very much for your answers!

Who is advising you on this to ensure you do not take on significant financial risk?

No one can reliably answer that, except perhaps clairvoyants, of which there seem to be plenty. One thing is certain, direct electric heating will make you poor!

Friends often say a lot, but whether they take financial responsibility for their “wise” advice is doubtful ;-)

Fortunately, there is no financial risk for us. So this is not an issue! :-)

Well, it could have been that you have good advice regarding efficient heating systems (both initial costs and running costs in the following years) or which ones offer a good price/performance ratio.

And the only ones responsible here, of course, are me and my girlfriend! 😉

Best regards!

How about using split air conditioning units and installing photovoltaic panels on the roof instead of solar thermal systems?

With split AC units, you can cool in summer while using electricity generated by the photovoltaic system for free. In winter, they heat using heat pump technology (please excuse my layman’s terms, this isn’t my field). To my knowledge, there is no Bafa subsidy for this, but there is KfW funding under the Energy Efficient Renovation program (efficient house), though it’s better to check other programs as well.

Split air conditioning units can be purchased for around 3.5 kW = 700 euros plus installation costs. You won’t find anything cheaper.

Although this is a form of electric heating, it’s quite energy efficient compared to infrared or other types of electric heaters. Additionally, no pipes or radiators are required, and there is no need for major demolition, just a small hole to be drilled in the exterior wall for the lines.

Before buying, I would recommend having a heating load calculation done—not online, though—as I recently took a provider of online heating load calculations to court because their calculation was nonsense (they didn’t even enter the data correctly), and the person was extremely rude beyond acceptable limits. (By the way, I won the lawsuit with flying colors.)

Heat load calculation. Never heard of that before.
But thank you very, very much! I will look into it.

For now, the favorite is the gas heating system. There won't be enough time to install it completely, so most likely we will first have the associated pipes installed. The radiators will be added sometime later.

However, the house is already purchased. So now there’s no way around it! 🙂

Hello,

When buying a house, you should consult an expert who provides a purchase consultation, reviews the documents, and inspects the property. This allows issues such as structural defects and legal aspects to be clarified, and a recommendation can be made. Ideally, the expert is also an energy consultant and can advise on possible renovation measures. This includes, for example, whether underfloor heating can be retrofitted. Depending on the screed construction, which needs to be checked, it may be possible to mill in the heating pipes afterwards if planning to renew the floor covering. Wood or briquettes can be an option, but only if you can reliably ensure continuous access to the energy sources and are physically able to handle them. If anything, I would only consider using them as supplemental heating, for example, in the form of a wood stove.

Even though there is no longer an obligation to remove night storage heaters (according to the new energy saving regulations), it is worth considering alternatives due to the development of electricity prices. This can certainly include a gas heating system! Without a basement, a gas condensing boiler can be installed in a utility room, kitchen, or hallway. There is likely no chimney, so one would have to be installed later, for example, on the exterior wall (stainless steel flue). These units are quiet, compact, and the small amount of waste heat generated can also be used in the living area.

Best regards, Erik
