ᐅ Replacing an Old Heating System with a Heat Pump or Gas Boiler Combined with a Domestic Hot Water Heat Pump

Hello, my gas heating system (roof heating central unit) is 22 years old, as is the solar thermal system. The solar thermal system is no longer functioning properly. The first builder recommends demolishing both the heating system and the solar thermal system and installing a Weishaupt heat pump. He has been installing only Weishaupt products for several years. A second builder recommends renewing the gas boiler and additionally installing a domestic hot water heat pump. A photovoltaic system has been commissioned with 9 Luxor ECO LINE HALF-CELLS M120/380W modules, which will be expanded by at least 3 modules when the solar thermal system is removed. The property is a mid-terrace house, fully equipped with radiators, with 106 m² (1,141 sq ft) of living space, housing 4 people, and approximately 10,000 kWh annual gas consumption. Postal code 76661, average annual temperature 11.1°C (52°F), standard outdoor temperature -10°C (14°F). According to the builder, the heat pump is to be installed on the roof. Regarding the hybrid system: can I install the heat pump for domestic hot water in the basement even though there is no existing hot water pipe? How extensive would the work be if additional piping needs to be installed? Installation in the attic is not possible.

It just needs to be properly decoupled; otherwise, the vibrations transfer to the wall and from there to the entire house... Why isn’t a footing foundation possible on that side? Placement on the ground is problematic because the distance to the property boundary would be only about 50cm (20 inches), and mounting the heat pump centrally at the top would be possible. I wonder if the sound propagation differs when installed at the gable end near the roof ridge.Tolentino schrieb:
Different in what respect?
Low-frequency sound tends to spread more spherically and is less affected by reflective surfaces.
How are the neighbors handling it? Both neighbors use gas heating. As far as I know, neither is planning to replace their heating system since both upgraded their old systems a few years ago.

So it’s best to discuss the future with heat pumps over a cold drink. ;-)
