Hello

I have now received an initial offer for my new construction project and am generally fairly satisfied with a first overall turnkey price of €370,000 (approximately $400,000), including flooring and painting work. However, I consider several of the individual listed items to be quite expensive. I would really appreciate a brief assessment.

The offer is for a Tuscan-style house with a basement, two bay windows (ground floor only), an additional covered area over both bay windows plus the terrace, and two prefabricated garages. Living area is 145 + 75 sqm (approximately 1,560 + 810 sq ft) of usable space. Unfortunately, the detailed cost breakdown is not very specific, so I need to discuss the offer further with the supplier before making a decision here.

Right now, I am particularly interested in the costs for the optional heat pump and underfloor heating:

The heat pump (Alpha Innotec, 800-liter (210-gallon) thermal storage tank, 6 kW heating element, outdoor installation) is quoted at an additional €28,000 (approximately $30,000) compared to a gas heating system.

In return, the underfloor heating line item of €13,000 (approximately $14,000) would be removed because it would be included with the heat pump.

Personally, these prices seem very high to me, so I would like to hear your opinion. Is this realistic for the given living area?

So, an additional cost of 15,000, otherwise it would be comparing apples and oranges.

You have to calculate which option is cheaper in the long run: gas or electricity. Also consider which one requires more maintenance, etc.

28,000 euros compared to 13,000 euros for underfloor heating leaves an additional cost of 15,000 euros for the heat pump (instead of a gas boiler).

Three questions:
What is the cost of the heat pump?
What is the cost of the gas boiler?
Is the drilling included, and what might that cost?

Since I don’t know the model, I have to rely on my prices. Our heat pump cost 8,000 euros, commissioning 2,000 euros, and the drilling 5,000 euros... so all in all
 15,000 euros seems about right. But that is just for reference. It does not relate to your specific building project.

Gas is not an option for me since there is no gas connection available. And I don’t really want to bury a gas tank in the garden.

 15,000 euros seems about right. But that’s just for orientation. It doesn’t relate specifically to your construction project.

I forgot to mention that it’s an air-to-water heat pump. Unfortunately, I don’t have detailed information about the heat pump since the quote only states it as above. But that kind of orientation was exactly what I needed. Thanks.

Ok .... so oil or how is the heating supposed to be done? Just asking because it might be optional.

Exactly, what part of the air-to-water heat pump should be optional if gas is not an option?

The additional cost is simply outrageous. As tox mentioned, you can get a brine-to-water heat pump for that price with a good deal. But not as an extra cost, rather as the complete system.
Where is the credit for the boiler, solar thermal system, and gas connection?
