I have a newly installed system (from Evohome Shop)
It was only used initially to enable plumbers to test everything was OK.
Yesterday I decided to turn it on only to find I was getting no heat at all ,I realised it was due to the fact the boiler relay had become unbound.
I have successfully rebound it and system works as it should.
My question is I would like to know if there is any way of checking that the relay is bound,without discovering no heat.
My boiler is in my loft and at 78 years climbing into the loft is a pain.
