Greetings,

I'm from the southeast of France. I am renovating a big old stone house that was previously heated by a big old groundwater source heat pump. The installation is a mix of underfloor heating, 50 years old radiators, a bunch of mysterious pipes going who knows where, and way too many circulators.

I had hoped the heat pump would last until after I had renovated the heating system, so I could retire it and replace it with an air source heat pump, but it blew a heat exchanger in December last year. So I accelerated the plan to replace it with an ASHP. Contacted a few installers. Hilarity ensued. Got fed up so ordered a LG 16kW R290 off the internet, installed it myself, put an enormous plate heat exchanger from an Olympic swimming pool heating system between the brand new machine and the old installation (still running on mostly rust and sludge), and tada! It works absolutely fine.

Still have to design and install the new system though. Then... I saw the heat geeks guys on Youtube. So here I am lol
