Hello everyone,
We are going to build a townhouse with 160 sqm + basement ( ). We are two adults, a 6-year-old daughter, and a baby on the way. We all like to take long warm baths or showers.
Our construction contract includes two possible heating systems in the price. I don’t want to start a fundamental discussion here about whether air-water heat pumps or gas/solar are better. Maybe someone has an idea and can give us tips on what would be more suitable for OUR building project and OUR family situation. Also, I have some specific questions...
(P.s.: Underfloor heating will be installed throughout the house, except the technical room. We also want a fireplace)
1. Gas condensing boiler with hot water storage (company Wolf, 4-8 KW, with 300 l storage water volume). Domestic hot water supply is central without circulation lines. 2-3 flat plate solar collectors included.
- Is 300 l enough for us "warm showerers" or will we run out of hot water by the end of the day?
- What is meant by circulation lines?
- Are 2-3 flat plate solar collectors enough? Our acquaintances are also four and have 12
OR:
2. Air-water heat pump (company Rotex HPSU Compact, 4-8 KW). With outdoor and indoor unit. 1 energy storage tank with 300 l storage water volume.
- Does anyone have experience with the device regarding noise?
- I once read that a photovoltaic system should also be installed with an air-water heat pump, but that is quite expensive, right?
Since we want a fireplace, the idea came up to combine a water-bearing fireplace stove with gas/solar and install a combined storage tank (or stratified storage tank?). What would that cost extra? Does anyone have experience with that?
What would you recommend to us? Thanks in advance!
