This is what I said in the preamble to my first intervention, the self-proclamation of a self-specialty, with pseudo skills .... But you are wrong about me ... Too bad.
I did not understand, your explanation on the thermal pad ...
I will respond to several observations:
Many people make hot water with the fuel boiler in the summer, despite a heat pump ...
This is nonsense, so obvious that I wonder how some installers came to recommend such a solution.
On the one hand, there is no worse boiler output than operating it for DHW.
1 / Power requirement 3/4 Kw for power (Average) 20 Kw = catastrophic yield.
2 / Keeping the boiler hot 24/24 H for 1 hour maximum actual use
3 / Higher Kw / H fuel price than EDF off-peak Kw / H
4 / maintenance + continuous sweeping of the boiler.
Doing a fuel recovery in succession associated with a heat pump is the same style, or even worse, because when the boiler starts cold (In case it does not make hot water) during the rise in temperature, the yield does not not exceed 50%.
We systematically recommend production by the heat pump, whatever the heat source, earth, water, or air. As soon as the hydraulic scheme is well managed.
I return to the reliability of refrigerator compressors. Thank you for re-reading my previous article. "90% of the fridges put in the trash have copressors in perfect condition"
How can you assert that it is not possible, just because it is your "impression" what the evidence is that you have about it. Free affirmations do nothing for people, especially if they are false ...
Regarding the energy efficiency and savings of heat pumps, you display purely theoretical figures taken from your books, while I speak of real facts in situation with more than 150 customers installed. I do not intend to advertise, but simply to reestablish truths that are beyond your knowledge.
The solar heat pump solution is indeed a technique that we have already tested. We are waiting to see the results. In our case:
- AIR BLOCK BI BLOCK split R410A fluid inverter system Power 18 KW
- SANYO double cylinder compressor with defrost without cycle reversal (SANYO patent)
- Buffer tank on the heating side 200 LITERS
- Multi-energy double envelope stainless steel tank with DHW. 300 liters immersed in 200 liters of primary heating buffer.
-2 solar collectors 20 vacuum glass superconductive tubes with heat pipe diameter 70 mm. connected to the multi-energy storage tank and coupled with the heat pump with automatic heat / heat selection control
I don't have time right away, but I will send you soon, various diagrams and photos of installations.
Sincerely,
Daniel.
