Hi
Any help on this problem would be great I have a 48 x 18 indirect cylinder. This was heated by an oil guzzling aga now gone.
I've replaced the top mounted immersion with a 36" one and with the integral 18" stat on max only get about 5 galls of hottish water. Not enough for a quick non power shower.
It seems to me the stat would be better longer or able to be turned up higher otherwise the water below 18" will never get more than tepid. The stat tube is only 18" so not possible.
The indirect coil is empty and disconnected. I really don't want to replace the grade 1 cylinder; any ideas? Thanks
