Hot water only when heating is on

[Arran]

I have a grant vortex heat only boiler with a 2 port set up. At present I only get hot water if the heating is on. Ive checked both 2 port valves and they seem to work (they both don't spring back when energised), Ive checked the tank stat for continuity but now I've run out of ideas, can anyone help please? Thanks.

Are you competent with a multimetre?

If I'm being honest then the answer would be no

Theres no shame in admitting that and it could potentially save your life. That being said I would urge you to get an engineer out. This could be a few things but it needs to be tested from programmer to zone valve, it could be the valve head, it could be as simple as a loose connection but without being there and a multimeter theres no safe way of testing.

I appreciate your response, in fairness I'm a groundworker and only have an interest in digging holes, I've called 6 plumbers and not one can attend for a week so I started to look at it myself but thank you. Im beginning to wish I had taken up a career as a plumber!

I've only just seen your response Arran. If you felt comfortable with a multimetre I'd happily walk you through it but electricity is a killer. For now put the HW zone valve to manually open, that way you will have HW when CH is on, alternatively use your immersion heater and turn HW off at programmer.
