Hello everyone,
does anyone have general experience, both positive and negative, with the company Lüumel from Coswig?
I currently have an offer for a heat pump with a horizontal ground loop. I have already read quite a bit about this online. I would be interested in hearing about your experiences here as well. Unfortunately, my offer is not very detailed, so I will get in touch with the company. But maybe some of you here in the forum can help in advance:
How does the seasonal performance factor (SPF) or energy consumption compare to other heat pump systems?
Have you had a simulation or calculation of the SPF done?
What is the impact or buildability of the buried pipes in the garden, for example regarding load-bearing or drive-over capacity?
Is a heat meter absolutely necessary?
What are the pros and cons of a horizontal ground loop? (I know this is a very general question)

- which actually sound rather alarming...Since most of this approximately 100 m² (1,076 sq ft) of upgraded area only affected the lawn and was evenly raised, it sounds worse than it actually was. Because we only moved in autumn 2014, nothing had been planted or landscaped yet.
Only the walkway behind the garage, where our trash bins are placed, was unfortunately damaged. The stones were pushed apart first in one direction and then in the other due to movement, and the foundation for the edging stones was broken. With about 1–2 cm (about 1 inch) of stone spacing, the path is definitely permeable to water this year.
I don’t think we need to discuss my case further. I just wanted to point out that a waterproof structure should not be installed and what consequences could result from that.
On the website, I couldn’t find specific information about the trench collector or which heat pump is being used. Lüumel specializes in the DV type. Why would they use a different one?
Functionality
The heat pump extracts heat from the brine mixture of the ground absorber through the refrigerant and charges the combined layered storage tank, which produces both heating and domestic hot water.daytona schrieb:
My initial questions have now led me to a completely different but certainly important topic: electricity tariffs.Hmm, I actually wanted to take advantage of the BAFA subsidy. Now I have learned that a second electricity meter is mandatory for this....

Who says that? The BAFA states in its conditions that electricity and heat quantities must be measured separately. That’s what I read a few days ago.

Sebastian797 Dec 2015 15:00Fortunately, my heating system has one – but they are all old-fashioned analog meters anyway. I had overlooked the BAFA regulations and was thinking about the grid operator instead.
2. An electricity meter wouldn’t cost much either – around 50-100 euros plus installation?
