Hello everyone!
We are currently considering what and how we want to build. It is about a new building that is to be constructed by a property developer. Currently offered is a 36cm Ytong exterior wall. I would like to replace the standard heating system with a gas burner and radiators by a heat pump with underfloor heating throughout the house and thus completely do without a gas connection.
I actually do not want to use an air heat pump because I neither want the noise nor the unit in the garden, and I am not exactly enthusiastic about the decreasing efficiency during the cold season.
However, a few questions arise for me regarding the design and implementation. On the one hand, I have no estimation of how much more expensive geothermal energy is compared to an air heat pump. Do you have any rough values? I would like to work with geothermal probes, i.e. drillings, as I consider it to be the most solid method.
But what if there is damage to the system? The technician can unscrew the air heat pump and work on it. Nobody would want to dig up the geothermal probes, right?
And how much space do you need for something like that? I thought that the drilling could also be done in front of the house, i.e. between the house and the sidewalk. There would only be about 3-5m of space there. If someone ever needs to get to the pipes, the pavement would have to be removed. I won’t be able to get heavy equipment into the garden later.
To increase the efficiency of the system in the long term, I would like to add photovoltaics later, but that would have to wait a few years for cost and planning reasons.
Thank you for your help!
