Construction costs for a 180 sqm single-family house

7 k€ for electric roller shutters? Is that the surcharge compared to having no roller shutters at all? For us, the surcharge from manual to electric was just under €100. At 7 k€ you would have to have 70 windows???

It is intended by the government that renewable energies become the standard. As a result, the Energy Saving Ordinance 2014 was tightened, the primary energy factor for electricity improved accordingly, and gas has deteriorated.

Compliance with the tightened Energy Saving Ordinance 2014 is therefore very easy with an air-to-water heat pump; meeting it with gas as a heat generator means an additional investment in insulation. For the property I estimate, the mentioned TEUR 10, since the desired property is not exactly small _and_ is to be built with a basement.

1- If you use an air-to-water heat pump, can you also do without the solar system?

2- How big is the cost difference between an air-to-water heat pump compared to the combination of a gas condensing boiler + solar?

EUR 7 ./. 25 = € 280.00 per electric roller shutter surcharge manual to electric roller shutter in BW.
