It keeps losing the radio link with the thermostat and will not heat the radiators. I increased pressure as it was low thinking this was the cause of the problem but it hasn't made any difference. I keep resetting the link and it works for an hour or sometimes less then goes again. Had over a week of waking up to a freezing cold house and I getting a little tired of it now. Any suggestions would be greatly appreciated. The boiler is about 4 years old and has been great up until now.

This could be 3 things
1. there is a fault with the stat
2. Where the stat is positioned in relation to your boiler
3. or your home wireless broadband can interfer as well

Hope this helps
