Does it work? yes. Was it installed as I would expect, yes! The Team was professional etc The only issue was setting up the "App" yes there is an app. It is a Free open source app which means that instruction and guidance is awful and is still showing some things in Spanish "periodo". I love our underfloor heating and having a radiator free house. So for that I thank you

The engineer came and inspected my inverter, checked that it was OK and reported that there was nothing wrong with it and no further action required. All done within 1 hour.

Rayotec were prompt, efficient, friendly and at a sensible price. They replaced my faulty solar inverter with a compact modern unit which has worked well ever since. Can't fault them.

Useless firm - they don’t actually do any software repairs or reboots. And they don’t stock dataloggers or replace them. Waste of space

Highly recommend James and the Rayotec team! We had a great experience using Rayotec for our extension’s underfloor heating. James was fantastic—he helped us choose the right product and kept us informed every step of the way. The installation was top-notch. Even with 50% glass in the room, as it is an orangery, the heating works perfectly and is very fast to warm up. If you're looking for a reliable company, definitely go with Rayotec.
