Questions about night storage and electric heating

hello first of all I am glad that I found the forum I might want to buy an old house about 500 m2 living space I find the house very cheap unfortunately there is no normal heating as there are only many old [nachtspeicher] heaters the seller tells me something about 50 euros per month that they can no longer consume is that possible? in any case I wanted to modernize the house but I think I won’t get a big loan for that and so I can’t install a new gas heating for the whole house what can you tell me about the old [nachtspeicher] heaters? would it help if I installed a solar system on the roof so that I get electricity cheaper? who can write me something about this and help me?

Hello,

...I might want to buy an old house about 500 m2 living space which I find very cheap, but unfortunately there is no normal heating, only many old night storage heaters

If something seems particularly cheap, there is usually a reason ;)

...the seller tells me something about 50 euros monthly that they can't consume more than that is that possible?

Yes, if the seller only heats one room in winter, sits at 10° C room temperature, or spends the winter in Mallorca!
Absolute caution is advised here, especially with this living area!
This supposed bargain quickly turns into a money pit!

...in any case, I wanted to modernize the house but I think I won’t get a big loan for that and so I can’t install a new gas heating system for the whole house

Do yourself a favor, evaluate existing properties only with a building services engineer and construction expert before you plunge into misfortune!

...what can you tell me about the old night storage heaters?

Pure money-wasting!

...would it help if I installed a solar system on the roof to get cheaper electricity?

Hardly!

...what about newer electric heating systems e.g. ....who can write me something about that and help me?

A good advice, find a sales-independent expert!!!!!!!

Best regards.

Hello Planetx,


First of all: be cautious with the seller's statements. €50 monthly heating costs for 500 m² living space, as Euro already mentioned, something doesn't add up, even if it were super insulated. Make sure to ask to see the energy certificate for the property; the seller is legally obliged to present it to you. If it is a consumption certificate, it reflects the consumption of the users over three consecutive years. This may also be from a longer time ago and thus does not represent the current situation. It is also possible that perhaps only one person lived there temporarily, resulting in very low consumption. Therefore, the consumption bills from recent years are also of great interest. A demand certificate reflects the building physics and technical condition of the building and provides a more accurate impression. Depending on the age of the building and the number of residential units, one or the other variant is mandatory. Additionally, it is recommended to take an expert along to the viewing, possibly even have a value appraisal done and the renovation costs estimated, so it does not become a “Euro-cent” pit.


Basically, replacing the existing heating system will be inevitable sooner or later anyway, because Nachspeicherheizungen bis 2020 gesetzlich abgeschafft werden müssen. So if you are going to renovate the house anyway, you should plan for a heating system modernization. From my point of view, a gas condensing boiler is suitable for several reasons. It does not require a storage room for fuels (oil, pellets), the chimney can be easily installed, e.g. through an external flue, the technology is quiet and highly efficient (efficiency 103%), has low CO2 emissions, and adapts through the use of a modular system to future lower demands, e.g. through the implementation of renovation measures over time.


Good luck with the house purchase!

Hello,

....., the technology is quiet and highly efficient (efficiency 103%), has low CO2 emissions and adapts ...

The high boiler efficiency is less interesting here, the decisive factor is the annual utilization rate. ;) This is only about 65..70% for poorly to moderately planned condensing boiler systems. For precisely planned ones up to 85%, depending on whether domestic hot water preparation is taken into account or not.
Best regards

Hello Planetx,

I can only agree with the others. €50,-- heating costs/month cannot be true.

If you really want to buy this house - definitely have an appraisal done (building fabric, roof, electrical system, etc.), there could still be quite a bit waiting for you.

Regarding the solar system: it would make sense with proper heat load calculation and in combination with photovoltaic and thermal solar, in addition to the gas boiler.

I would advise against a new electric heating system for the WNF, unless you renovate the whole thing according to passive house standards.

Best regards
