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?

As a general rule:
If possible, have the individual components broken down by price.
The additional cost for closer spacing of the underfloor heating pipes is likely between €500 and €1000 (approximately $550 to $1100).
The heat pump alone costs around €8000 to €10,000 (approximately $8800 to $11,000), which is already quite expensive.
Commissioning is about €1000 to €1500 (approximately $1100 to $1650).
A stratified buffer tank is low quality and only masks poor hydraulic design—unless you have a second heat source like solar or a wood-burning stove.
A gas boiler costs about €5000 to €6000 (approximately $5500 to $6600).
From my gut feeling, you should consider another heating installer who really understands heat pumps.

Layered storage tanks are useless and only hide poor hydraulic design. Unless you have a second heat source like solar thermal or a wood-burning stove.
A gas boiler costs about €5000-6000.
Off the top of my head, you should look for a different heating installer who really knows about heat pumps.I still plan to break down the components individually. The price of €28,000 includes the underfloor heating. The €13,000 only applies if I do not take a heat pump. However, that would mean I would need a gas tank in addition to the gas boiler, which I do not want.
Regarding the layered storage tank, there is an additional heat source: a solar thermal system is already included in the price.

toxicmolotof2 Jun 2018 01:32Sorry, I hadn’t read the part about the air-to-water heat pump. Then it does seem a bit expensive, BUT I don’t know the exact scope of what is included, excluded, or whatever in each option...
This also seems to be a common tactic—to make everything as complicated as possible.
Here, the air-to-water heat pump includes underfloor heating and decentralized fresh air supply (still: wtf!), while there’s the gas heating without underfloor heating, but that costs extra. However, the controlled mechanical ventilation, not decentralized, is included, as well as solar thermal and a gas tank?!?
What happens to the solar thermal system with the air-to-water heat pump? That doesn’t make sense anymore then. Both systems (air-to-water heat pump + solar thermal) work great individually if you don’t need them in summer. And in winter, both systems provide only moderate performance in their own way...
So, prices per individual module, and then you can compare. Otherwise, in the end, you won’t know what you ordered at what price and with which features.

Solar thermal systems are no longer justified with an air-to-water heat pump and should be removed. They are necessary with a gas or oil system to achieve the required factor of renewable energy. Have a domestic hot water cylinder with 200 or 300 liters (53 or 79 gallons) installed and remove the stratified storage tank.
