Glow worm space saver constantly heating hot water

[Last Plumber]

Have a look at lecy meter after you used hot water for a bath. It will spin quick if immersion is on. They have a stat so if tank is full of hot water it may have switched off.

Or flash quick if it's new.

Best to get someone pro to look in though. Sounds like you need advice from someone who's had eyes on the job

All, sorry for the late response, thanks for your contributions. I was only looking at the pilot light and reasonably sure it the immersion comes on in small amounts. Im now in the situation where the rads to the pipes get hot when i only switch the hot water on, assume this is a problem with the 3 way valve now too..time to get the experts in.
