Very happy with the combi boiler which was fitted in the summer 2022, however it came with a software fault that was only evident when the cold weather came in.
Peter Maxwell the software technician found the fault and had an engineer come out to fix.
As this is a new boiler system working with an app,updates are essential, still work in progress with the app.
