Hello everyone,
I’m really glad to have found this forum and am looking forward to the exchange of ideas.
Regarding the topic, I need a plan for the most cost-effective installation, procurement, and heating cost optimization for a new building following an older standard. So, not a KFW house or similar, since it will probably be considered an extension of an existing building from 1970.
Two residential units will be built near Winterberg.
There, I only need hot water for showers, for two people each, so four in total, who might shower at the same time in the mornings.
The apartments in the house will probably not always be occupied or will be used alternately.
There is no gas connection available. The sun hits the roof from around 10 a.m.
I was thinking of using a domestic hot water heat pump for the hot water… would that be sufficient?
Then I thought about heating with an air conditioning system… does that work? Two units of about 100m² (1,076 sq ft) each. How should the system be designed?
I expect less effort in installation and planning with that.
Would that be manageable? Also, I would like to heat two outdoor jacuzzis… what would be the most cost-effective way to do that?
Looking forward to your opinions….

Audiobampa15 Apr 2023 08:37I wouldn’t do it myself either; I just want to prepare everything from a planning perspective in order to be able to issue tenders and compare quotes. It’s difficult to get a full overview of everything.
The alternative would be the Daikin Stylish. They only state that the same capacity is sufficient for 50m² (540ft²), according to their specs. If I convert the capacity based on BTU to watts, it fits again... but it consumes more energy... the black wall unit would look nicer though... but then I’d have to pay 1500€ more?

I would have a company come in, plan the installation, and prepare a quote.
Then I would ask two other companies to provide competing quotes and compare them.
Comparing individual prices from online quotes is not effective.
