Hi ,just joined ,im a british expat living in france full time for over 20 years,Mr Macron in his bid for less pollution has made it impossible to order a part for a oil fired boiler ,ok if the repair company have it the part in stock but cannot order one in ,no new instalations reliant on oil neither,wood ,gas and pellets are ok still. With this in mind and my old oil boiler looking like something from frankensteins castle i've had a mitsubishi  air /water ecodan system fitted and will be picking your brains later regarding the running been in over 12 months now,got the basic running sorted so just need the tweaks for efficiency, hope you all have a great 2025 and look forward to your advice 

Cheers Coeurdelion

Welcome, interesting to hear how other countries are dealing with these issues.

Well, Richard, good to see you've found us at last. Vive la difference!

Welcome. I replaced an old boiler by a Mitsubishi Zubadan air-water heat pump a year and a half ago. The help of the good people of this forum was invaluable for doing the calculations.

 

I imagine you have radiators rather than under-floor heating?

 

- The key to efficiency is low flow temperature.

- I imagine the heat-pump is auto-adaptative? In that case you are best off letting it do its thing rather than dictate strictly what it is supposed to do. Just provide a starting curve in accordance with your calculations.

- Old-fashioned thermostatic valves on the radiators are your friends. Remember that the valve in the room you have the (portable?) thermostat in should be fully open. If you plan not to move the thermostat, you could keep it in the naturally coldest room in the house and just install a regular valve there, as opposed to a thermostatic valve; again, keep it fully open.

 

PS. I live in the Paris area. I imagine you had the heat-pump installers take apart the heat-pump themselves? Otherwise you lose most of the installation subsidies.

PPS. I'm a semi-newbie, and am very glad to be corrected by experienced people in this forum on anything.

Thanks for the informative reply Garald ,not sure about the installers taking apart the heat pump bit in your reply but didn't bother with the installation subsidies ,luckily I had a few euros put aside for the work.

Sorry, I mistyped. I meant: if the heat-pump installers took apart *the old boiler* themselves (and have RGE certification, which they should have), you get much more in the way of subsidies.

 

No reason not to get 4K+ in free money (a completely justified subsidy if you ask me). Or more like 1.5K if you didn't know that silly rule and somebody else took apart the old boiler (that was my situation; I went through an, um, eventful renovation, initially led by someone who pretended to be an architect but wasn't - not exactly an unknown occurrence in France, as it turns out).
