Hello everyone,
We are planning to build a single-family house without a basement (ground floor + upper floor) of about 170 sqm (1,830 sq ft) and are looking for a good air-to-water heat pump for it. The unit should be inverter-controlled and a monobloc system for outdoor installation. It should be as efficient as possible, but at the same time as quiet as possible.
Our builder usually installs heat pumps from Alpha Innotec. Either the LWDV or LWAV+ model would fit the above criteria.
What do you think of Alpha Innotec and these two models? Does anyone have experience with them?
I would also appreciate recommendations for other systems and manufacturers.
Best regards,
Felix

Pipe spacing 7.5cm (3 inches), 5cm (2 inches) in the bathroom. At least one additional wall in the bathroom. All loops between 80 and 100 meters (87 to 109 yards). Such a rigid rule for pipe spacing is not necessarily effective. However, the second tip should be followed.
The first step should be a room-by-room heating load calculation (not an estimate). Based on this calculation, the underfloor heating should be designed, and if needed, additional wall heating (usually in the bathrooms). The loops should be as equal in length as possible and not longer than 100 meters (109 yards) due to pressure loss in the heating circuit, hydraulic balancing, and power consumption of the circulation pump.
Furthermore, the heat pump should work directly into the heating circuit, without a separator buffer, combination buffer, mixing components, or water-based ladder system in the bathroom. If there is no exemption for ERR (= Efficiency Reduction Controller), it should be equipped with its own fuse to allow easy power disconnection later. The connection of the heating circuit manifolds should be generous to minimize pressure loss before the manifold.
The selection of the heat pump should only be made after the heating load calculation is available, with no safety margin added for anything.
Whether your heating installer will agree with this is another question...
Flow30 is a very good tip.
Completely forgotten, the pipe diameter of the underfloor heating should also be considered.
