ᐅ Is a Separate Meter and Electricity Tariff for an Air-to-Water Heat Pump Beneficial?

Hello everyone,
We have an air-to-water heat pump in our newly built house and are considering whether it makes sense to install a separate meter for it and to get a separate tariff. Do you have any experience with this? Is it worthwhile?

This is the lowest/basic standard you can choose. 15cm (6 inches) is really borderline.
This is a tight installation – 5cm (2 inches)! But it also means triple the number of pipes.
However, it only works if each loop is no longer than 100m (330 feet). How many loops are there? What is their length?N

The material cost is almost negligible – 100 meters (330 feet) of MSV pipe costs less than 100€ (euros). Stapling just takes more time.

Each pipe length barely exceeds 100m (330 feet). Almost a perfect fit. It’s not a DIY design but calculated by the engineering firm to match the room heating load.D
Deliverer7 Jun 2021 10:42There is a sweet spot somewhere. (From experience, it should be around 8cm (3 inches). Although that also depends on the pipe thickness...).
And, of course, the load is lower when the house is better insulated.
The pump doesn’t necessarily have to work harder if the spacing is smaller. Two loops on the same area mean less flow per minute. More important for the pump are proper supply lines between the manifold boxes and the heat pump.

This shown "extreme" has a total heating circuit length of about 500 m (1,640 ft) for 25 sqm (270 sq ft) with actual 5 cm (2 inches)! Far from 3 x 100 m (3 x 330 ft). No, it doesn’t – as mentioned, each is a bit over 100 m (330 ft). And it really is 5 cm (2 inches). I installed them myself 😉
In the end, it’s not a big deal if some circuits exceed 100 m (330 ft). It’s a combination of different factors (pump, temperatures, pipe diameter, etc.).
