Existing house: Heating modernization

Hello everyone, I bought a house built in 1968, and currently there are storage heaters installed... Not insulated, no pipes in the house, etc... I now want to modernize the windows and the heating system.

I would like to completely convert the heating system... Now I am almost decided on gas,...

But since there is no gas pipeline in my street, I would have to pay 12,000 euros for the main pipeline extension...

So I am already considering having a (rental) gas tank buried in the garden...

I already have offers from Primagas, Rheingas, and Knauber...

Who of you has experience with liquefied gas? Are you satisfied with it?

What else would you recommend to me?
I am not so sure about electric heating and how economical it is, despite solar or photovoltaic systems,
My roof would be perfectly oriented for a system, but I don't know how the radiators heat...
I think gas is better in terms of heating quality

But since there is no line on my street, I would have to pay 12,000 euros for main line extension...

It will be a calculation exercise whether it’s worth it (but I don’t think so).

I’m not so sure how economical electric heating is, despite the solar or photovoltaic system,

Night storage heating is not economical at all – but with the investment for a gas heating system plus connection, you could probably heat for 20 years.
Heat pumps are economical. But your house is rather not suited for that.
Why not invest the extra cost for the gas connection in insulation and install a future-proof heat pump? That’s still subsidized.

I think gas is better in terms of heating quality

What is heating quality? Either the house gets warm or it doesn’t.

As long as it is unclear what you want to achieve, it is difficult to give you advice. Many just want the most economical option. Others place more value on climate protection. A third group has special design requirements - e.g., the absence of radiators. Others wish for a higher proportion of radiant heat because they feel particularly comfortable with it.

Financially, there are actually quite good grant programs - depending on what you do. This can economically help to make a decision for a more climate-friendly option.

Here and today to still rely on gas, I consider economically risky and ecologically unacceptable. Austria has just banned gas, Germany must do so soon as well, otherwise Paris won't work.

Especially with the current subsidies AND the missing gas pipeline, one should definitely opt for insulation, surface heating, and heat pumps. Alternatively, for even more insulation (passive house standard) and air-to-air heat pumps (aka air conditioners. They have also been subsidized since this year). With photovoltaics, you heat with your own electricity during the transitional period. It doesn't get any better than that.

As long as it is unclear what you want to achieve, it is difficult to give you advice.

That's right; you should describe your project in more detail in order to get various and also well-founded results. If you also once free yourself out of interest from the "usual suspects," there are many possibilities and niche products that might suit you better than you think. It depends on the house and your desired goals; moreover, I would only keep an eye on funding and always pay attention first to what I WANT to achieve and only after that whether I get funding for it. Then you can make a final decision. For €12,000 more costs, you can heat for a long time and still it can be the right choice. We currently have a gas tank here; this is rather the usual standard in the East. In the new development area, some people have also had it buried lately. I see no reason not to do that; the heating runs perfectly, I think in terms of function there is no difference, more important would be the quality and implementation of the technical installation in the house. Equally conceivable could be a solution with electricity; there are also modern and innovative solutions on the market that are no longer comparable to the old night storage heaters, especially since you have photovoltaic in mind. For example, we do something like that in a new build and then have a nice wood-burning fireplace. But all that depends on your goals and preferences or, as writes, on your respective decision criteria.
