Hello,
The first tests were successful with thermostatic valves fully open, but as soon as I adjusted them, the boiler started to lack water flow. The differential valve provided for in the estimate had not been installed.
I continued my tests by opening the taps, but as I do not need some, I realized that it would default below 15 l / min of flow. In addition we hear traffic noise in the radiators. I was not told that it was a bad idea to put thermostatic valves on my 17 radiators.
Another concern, the water law is set between 15 ° and -10 for outdoor temperatures and between 40 and 55 ° on the water circuit side. Why does it continue to run with an outside temperature of 20 °?
The remote control of the indoor unit allows daily programming, but as we do not enter temperature data but a level 1,2 or 3 without further explanation, I wonder if it is not intended only for the DHW option that I did not take?
As the installer must come back for the differential valve and I do not have the invoice yet, I will ask him on Monday to add a room thermostat allowing me to really program the operating ranges and as much add the right options , to include them in the tax credit.
Wouldn't a balloon be essential, in my case?

In general (not only for heat pumps), I was always told that it was indeed necessary to leave a minimum flow in the circuit (so some radiators without thermostatic valve).izentrop wrote:I was not told that it was a bad idea to put thermostatic valves on my 17 radiators.
Conventionally, we leave open the radiators of bathroom, or rooms to the north.
It seems to me that a room thermostat is actually recommended for proper operation.izentrop wrote:As the installer must come back for the differential valve and I do not have the invoice yet, I will ask him on Monday to add a room thermostat allowing me to really program the operating ranges and as much add the right options , to include them in the tax credit.
In this case, it is rather the radiators in the room where the thermostat is located that are left without thermostat.
If you want a thermostatic valve on each radiator, I think so.izentrop wrote:Wouldn't a balloon be essential, in my case?
On the other hand, a use with room thermostat and some radiators without thermostat is also a solution.

Re: Need advice for air / water heat pump Altherma radiators 14 kW
Thank you Gaston,
I tried again and indeed, the room thermostat is required.
My installer reaffirmed to me that the buffer tank was not necessary in my case.
I was also told that 70 l of water was enough for 14 kW. My calculations give more than 200 L distributed in the circuit, which means that I can close part of the radiators without problem, provided that I open the valves of the others.
I plan to adjust the thermostatic valves more open than normal.
For now the heating is off, they are still announcing hot weather all week. It is good RC
