ASHP Ecodan L9 error - No Heating but Hot Water
@phoenix15 I hope you have success with finding a Mitsubishi accredited engineer very soon. Esp. If you have a leak as well.
it may be that over time you may have lost the rust inhibitor that stops the rust deposits build up. So if the plan is to flush your system that should mean you’ll get a fresh dose of inhibitor.
best of luck @phoenix15. Let us know how you get on?!
@phoenix15 Mars has a list of reliable ASHP companies, I assume this would not only be for installation but all services relating.
Where in the country are you?
AAC Group Ltd covering the Kent Area for design, supply and installation of ASHP systems, service and maintenance, diagnostics and repairs.
@ashp-bobba Cumbria.. we have contacted the local ones we could find. Getting them to actually turn up seems to be the problem!
@phoenix15 Sorry to hear that, we are all the way down in Kent and we only cover Kent otherwise I would send you someone to help.
