ᐅ Heating System for New Construction – Which Is the Best Option?

Hello,
starting next week, I will be building a single-family house of 180 m² (1,938 sq ft). Many details have already been finalized, but I keep changing my mind about the type of heating. Initially, I was convinced to go with a gas condensing boiler combined with tube collectors. Then I considered an air-to-water heat pump. Now I am leaning towards a pellet heating system. There is also the Vitovalor from Viessmann, which I find interesting—generating electricity myself..
Basically, I want to be as self-sufficient as possible regarding energy supply. So, perhaps an air-to-water heat pump with photovoltaic panels and a water-based fireplace? I’m a bit overwhelmed. Maybe someone here can give me some advice on what is feasible..
Best regards, Florian

He therefore recommends getting used to this ugly outdoor unit of the heat pump.Even though you shouldn’t primarily choose an air-to-water heat pump based on appearance but rather on heating load, take a look at Ochsner or Alpha Innotec; they offer units that I find at least acceptable from an aesthetic perspective... The main criterion should be the heating load, determined using the heating load calculation mentioned earlier.

Heat load calculation!!A vicious circle. Unfortunately, this only happens after the construction contract is signed, as only then does phase 4 begin, where the heat demand calculation is carried out. And anything that is not included in the contract beforehand and gets changed later will likely come at a high additional cost.

The drilling costs me 6,700 euros for a 5kW heating system.So, I just called and asked for a price estimate. The drilling alone will cost between 12,000 and 15,000 euros for an 8kW extraction capacity... You really have very favorable conditions for homeowners where you are. Here, the limit is usually 100 meters (330 feet), sometimes even just 60 meters (200 feet). Going deeper than 100 meters (330 feet) requires a special permit from the mining authority, which involves considerable effort - that’s what I was told. It will probably end up being an air-to-water heat pump after all...

Some of it was also estimated based on best guess.
The contractor said the drilling company offered a flat rate.
The duration and other factors are the company’s risk.
This was also how another offer was calculated, but that one was already for 9,000 Euros.
However, the company drilling now has already done drilling on site before, so they might have some experience there.

Can’t you commission them separately and then provide them later?I probably won’t have any other option, because otherwise I won’t be able to negotiate anything once the construction contract is signed. After that, any changes become extremely expensive.
