Which heating system

Hello,

I am new here and hope to ask in the right thread. :-)

So my girlfriend and I are buying a house (built in 1998). However, there is only a night storage heater installed in it.

Now the question: What would be best for us? We don’t have a basement, so an oil heating system is not an option. Neither is underfloor heating. Heating with wood and briquettes is also not possible.

So then it’s probably a gas heating system, right?

An acquaintance told me, however, that there may be subsidies regarding the night storage heater if we install a solar system on the roof. Does anyone know anything about that?

Thank you very much for the answers!

Hello,

....So my girlfriend and I are now buying a house (built in 1998)...

Who is advising you on this so that you don't get into significant financial risk?

....Now the question: What would be best for us?....

No one can answer that reliably unless they are clairvoyants, of which there apparently are plenty. One thing is certain, direct electric heating will make you poor!

...A friend told me, however,...

Friends usually tell a lot, but whether they take financial responsibility for their "wise" advice, I would not assume ;-) Regards

There is fortunately no financial risk for us. So this is not a problem either! :-)

Well, it could have been that you have good tips regarding economical heating systems (both purchase costs and costs in the following years) or which ones have a good price/performance ratio.

And the only ones who are liable for anything here are, of course, only me and my girlfriend! ;)

Best regards!

How about climate split units and instead of solar thermal, rather photovoltaic panels on the roof? With the climate split units, you can also cool in the summer and use the photovoltaic electricity for free, in winter they heat with "heat pump technology" (forgive my layman’s wording, it’s not my field). As far as I know, there is no Bafa subsidy for this, but KfW funding in the Energy Efficient Renovation (Effizienzhaus) program, better to inquire with other programs. You can get climate split units, for example, 3.5 kW = 700 euros plus installation costs. It doesn’t get cheaper than that. Although this is also an electric heating system, it is quite energy efficient compared to infrared or other electric heating. Also, it requires neither pipes nor radiators and you don’t have to tear anything open, just drill a small hole for the cables through the house wall. Before purchasing, I would have a heating load calculation done, but not online, as there is a provider of heating load calculations whom I recently took to court because the calculation was rubbish (not even the data was correctly taken) and the gentleman was outrageously rude to the extreme (by the way, I won the lawsuit with flying colors).

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

The favorite for now is the gas heating. There won't be enough time to install it completely, so we will most likely have the associated pipes laid first. The radiators will be installed at some later point.

However, the house has already been purchased. So we can no longer avoid it now! :)

Hello,

when buying a house, you should consult an expert who conducts a purchase consultation, meaning they review the documents and inspect the property. In this process, issues such as construction defects and legal aspects can be clarified and a recommendation can be made. Ideally, the expert is also an energy consultant and can provide information about modernization 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 subsequently mill in the heating pipes, provided that renewing the floor covering is planned. Wood/ briquettes can be an option, but only if it can be permanently ensured that access to the energy sources is available and one is physically able to handle it. If at all, I would only assume supplementary heating, e.g. in the form of a wood stove.

Even though there is no longer an obligation to dismantle night storage heaters (new energy saving ordinance), it is worthwhile to consider which alternatives exist due to the development of electricity prices. This can certainly be a gas heating system! Due to the lack of a basement, a gas condensing boiler can be installed in a utility room, in the kitchen, or in the hallway. There is probably no chimney, so one must be retrofitted, for example, on the facade (stainless steel pipe). The devices are quiet, compact, and at the same time the small amount of waste heat generated can be used in the living area.
