Poolex pool heat pump for heating home?

There are several points to improve, for starters I will isolate the big tube in 50mm behind the cap (see photo), about 2x25cm without insulation ...

Hello, after some research, I realize that the COP that I calculated are in fact COP system.
At 15 ° C I have a system COP of 3 while the machine COP announced and 5.76, so little better to do ...

The COP system is the COP that must be retained in the first place. Then comes the COPA which is even lower because it takes into account the whole year. By isolating the pipes, reducing the energy consumed by the PC circulators and reducing the set temperature you will improve the COP sys but it is difficult without real time measurements.

For COPA, I planned this summer to put sensors and a computer to measure and record the values ​​over the next winter.
For now, the temperature sensors (seen in the photo) give me the DeltaT, it will help me I think for the insulation of the pipes.
Moreover, I made several readings by changing the speed of the circulator (V1, V2, V3) and it is in V2 that it is the most conclusive, in V3 it makes noise while consuming more, whereas my pipes are clearly not big enough, they are 4 Per of 16 / 13, but I can also improve here by putting 20 / 27 connections in place of the current 15 / 21 (x4)

In order of importance in a system COP is the insulation of the pipes, then comes the optimization of the consumption of circulators.
A bad sizing system causes bad results ... it's all the misfortune of PAC in France.

Hello, here is my report after a little more than one month of use:
From 4 March to 4 April, ie 1 months:
Heating = 603.7 kWh is 87 €
Hot water = 187 kWh is 27 € (it is for comparison with gas)
A total of 114 €
For the same period in 2015 in town gas, low temperature boiler with suction cup (yield 92% max)
Heating + hot water = 2882 kWh is 192 € (at the time)
Very positive balance, -40% on the invoice ...
Now remains to know if my energy balance for heating alone and correct:
- Home of a little more than 200 m2 (600m3) on the right bank of Bordeaux
- Average internal temperature at 7h30 in the morning 21.01 ° C
- Heating consumption approx. 600 kWh
- For the month of March, Infoclimat gives 258 DJU (18), that is 351 DJU (21) which is my temperature.
Thanks to the connoisseurs for giving me their opinion.

Hello,
Thank you for your feedback, I would like to do the same type of installation? Do you have a little more information about the reliability of your installation? Thank you in advance
