Is a new heating system needed instead of a night storage heater in the house?

Hello, I am not directly the builder, but I am planning to buy a house that is currently equipped with a night storage heater. From everything I have heard so far, this type of heat generation is not so optimal, and there are conflicting statements that from a certain point in time this type of heating will no longer be allowed.
My question now is, does anyone know reliably whether it will actually be the case in the future that the stoves / the night storage heater must be replaced? And how high should one estimate the costs for a replacement? It is a small older property (approx. 100 sqm living space / built around 1906 / old farmhouse). There isn’t much room for a large boiler. The seller states that the heating costs are about 110 EUR per month (around 1300 EUR per year total), I somehow can’t quite believe that. And if the heating system is replaced, you surely have to change the water supply as well, which will bring additional costs?
Many thanks in advance for the answers from the experts.

Hello,

...., but I am planning to buy a house that is currently equipped with night storage heating.

I would think that over very carefully!

...My question is, does anyone know reliably whether it will actually be necessary in the future to replace the ovens / night storage heating?

Yes, from 2020. Regardless, this heating system is the most expensive type of heating in terms of consumption costs.

...The seller states that the heating costs are about 110 EUR per month (around 1300 EUR per year total); somehow, I can hardly believe that.

The seller will make every effort to present the consumption costs as low as possible. As a buyer, you also have a legal right to an energy certificate according to the Energy Saving Ordinance!

...And if you replace the heating system, you will surely also have to change the water supply, which will bring additional costs?

That’s right, heating and hot water supply are significant cost factors in a single-family house.
So be careful, such properties quickly turn into money pits afterwards. Decisions should only be made after consulting an expert in construction and building services engineering.

Best regards

Thank you very much for the information. I was unsure about that, but I will talk to the people again, because I am willing to take on the conversion work, but then the price should definitely be discussed again. It is absolutely too high.

Hello Gaga,
I would have an air-to-water heat pump installed. The installation costs are significantly lower than with geothermal energy and faster.
I installed one with my friend in his house from Mitsubishi Ecodan, the device is very quiet and has a good COP value. The chimney sweep no longer comes into his house. You don’t need much space for something like that, the indoor unit is about the size of a refrigerator or you can even take a compact unit, it is completely outside, only the buffer tank is in the basement or technical room.
You just have to install larger radiators than with a normal heating system to keep the flow temperature as low as possible. The heat pump electricity is also generally cheaper than the standard tariff, but it is also determined by the local utility company.
I hope it helped you.

Best regards

Hello,

...I would have an air-to-water heat pump installed.

A general recommendation that can definitely be considered. Building, climate location, user behavior, etc. must first be checked for suitability for an air heat pump!

...heat pump electricity is generally cheaper than standard tariff, ...

HT / NT tariffs are not always the cheaper option, especially with air heat pumps. This should be calculated (or have it calculated) beforehand, because air heat pumps depend on their source, outdoor air (seasonal performance factor). Especially with higher hot water demand relative to heating, the high midday temperatures are very interesting. And here an HT is given.

Best regards.

It was not a general recommendation, it was a recommendation and I only shared what I have had good experiences with myself. I only know that everything is better than night storage electricity! Air heat pumps are always better than night electricity, and even 1:3.2 (2°C) is always better than night storage heating. Our municipal utilities offer around the clock for 17 cents/kWh, or 13 cents at night. But in any case, it is up to everyone individually. There is no standard solution for everyone.
