Hello,
we are urgently looking for the best manufacturer of air source heat pumps. Our foundation slab for the new construction should be finished next week, but we just received a call that district heating is not feasible as planned, so now we need an air source heat pump. Which manufacturer is the best? We urgently need advice.
Best regards from Saarland

Switching to an air-to-water heat pump is, in my opinion, the wrong approach. Is there an energy consultant involved, an overall concept, a qualified heating load calculation? The worst thing now is to make a hasty decision for something that will operate for the next 20 years. If necessary, the current construction pace should be slowed down first, coordinating with the planner/developer and possibly specialized planners. Depending on the needs, location of the building, plot size, and planned energy standard, there are various production options—not just an air-to-water heat pump. Other technical options include ground-source heat pumps, as well as gas heat pumps, if a heat pump is required based on the overall concept.
Combinations of different energy sources are also conceivable, such as solar support for domestic hot water generation and heating support combined with natural gas, etc. At this point, the energy consultant or the engineer responsible for the energy concept must be involved to keep an eye on investment costs. These costs are high for a heat pump, low for a gas condensing boiler—especially considering that district heating is planned and the available budget may be very limited if a subsidized district heating connection is involved.
Best regards, Erik

At the moment, however, you are no longer referring to gas or its associated noise as objectively as you did at the beginning of your membership. Is this the beginning of concerns, or is it already quite apparent that gas will face more challenges in finding its way to customers in the future?
Why are the investment costs for an air-to-water heat pump higher than for a gas condensing boiler? That used to be the case a few years ago, but not anymore, as the sales figures for these heat pumps have increased significantly. It is also new to me that builders would not have to bear any costs (often comparable to the credit resulting from the omission of a heat generator) to have a new building supplied and heated with district heating at all?
District heating does not have to be subsidized; in times of scarce land resources, its use as a heat source is simply written into the development plan and that is that. I have yet to come across any real promotion for this type of heat generation; one might be suspicious of ulterior motives 😉
