Hello everyone, we received a brine water heat pump with earth baskets in connection with an offer for a prefabricated wooden house. Does anyone have experience with this? Electricity costs? Problems? There is hardly any information available about these earth baskets. Or does an air heat pump make more sense? Or maybe a simple and well-developed gas heating system, since you can heat for a long time with the extra costs of the heat pump? But due to the now also increased subsidy, a heat pump does make sense, right, what do you think? Thanks

Many will contradict me immediately. Wherever gas is available, I install gas devices as condensing units. Gas has a very high energy density and gas will remain affordable in the near future. The devices are proven, low-maintenance, and relatively small. The widely used air-water heat pump tends to be more problematic in that regard. I had a construction site in the shadow of a mountain (cold air basin). That probably wouldn’t have worked at all. I believe the builders there are quite happy with the gas boiler in combination with FH.

Gas alone is not permissible. A heat pump (as an air-to-water heat pump) can, but does not have to be, cheaper in acquisition than a gas heating system + necessary additional measures. Geothermal energy is the nicer technology, but usually only economical through own work (ring trench collector) and because of the higher subsidies (BAFA) compared to an air-to-water heat pump. However, I am not familiar with the latest changes in subsidies in 2020.

In cold and snowy regions, I would prefer geothermal energy.

Ongoing operating costs compared to gas are up to 50% lower with a well-planned heat pump and higher than gas with poor implementation and operation.

Gas is more fault-tolerant in implementation. If one can supervise and ensure reasonable planning of the hydraulics and heating surfaces for a heat pump, then in my opinion a heat pump is the much more sensible heating system, as it is cheaper to operate and without fossil fuels. Reading up on and supervising the planners and craftsmen by the builder is then advisable.

From the perspective of a practitioner, I can understand that well; heat pumps are not a self-runner compared to gas heating.

Geothermal baskets are usually expensive and in our case it was a rejection offer. Google er ring trench collector.
