Hi! My first post here.
I have a vented hot water tank, it's one of these - Gledhill SE26X18IND - it appears to be good quality. It is heated by an oil boiler with central heating in a Y system configuration. The pump, zone valve and timer / controller are new. After running the HW heating in the morning, the water in the tank is very hot, but by the evening it's lost a lot of heat. We have a 2 bar power shower and I use it each morning, not for excessive periods, and I can tell the water is still really hot when I get out. So, it seems to me I am losing heat from the tank during the day. The tank is insulated with foam ("EnviroFoam" they call it).
What can I do to reduce heat loss in the tank? I have yet to insulate all the pipework - could this be the cause?
Sorry. I know these sound like stupid questions. I realise heat will be lost from the top of the tank and the pipe coming out of it, but surely not that much so as to be noticeable over 10 hours. It's obvious that I can improve the tank insulation, but do I need to? I suppose what I'm asking is "Is there anything else that might cause this?"
