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.

Only the equipment? That seems quite expensive to me. But it could also be that these are simply the current prices. A lot has really changed in the last two years. Delivery times of up to a year, etc. It’s terrible!Complete offer including installation and 9 radiators: 35,700€ (approximately $37,700). Additionally about 2,500€ (approximately $2,640) for a mobile crane and electrical installation. With Vaillant, I get a price of around 26,000€ (approximately $27,400) using the Heizungonline calculator. How realistic is that price?

Lead times of one year, etc. It’s terrible! Offer for a new gas boiler and tank with heating coil 15,900 including VAT plus 700 Euro crane fee. Is this the average price at the moment? Offer for a heat pump without radiators 30,000 including VAT. That’s somewhat more acceptable.
