My hot water tank has stopped getting properly hot.Â* The heating is

Any (sensible) suggestions would be appreciated.

Standard open vented indirect tank and boiler with nothing fancy like
weather compensation etc. No recent issues.Â* DHW timer set to run
when the heating is off.

Cheers people


Can you feel hot water entering the DHW coil as and when it should?

It feels hot but of course I haven't held onto the pipe for the full
time the boiler is running....

If your boiler is supplyng water at 80+ C then it wouldn't 'feel'
hot, it would be 'ouch, fkit' hot.
Can you check your 3way valve and make sure it is operating properly ?.
