Please help me!
Fitted a new indirect hot water cylinder in a bungalow with an emersion.
The Problem im having is the central heating goes on for 7 to 9 hours on day 1. Morning of day 2 there is no hot water left in cylinder. There is no leaks in the open vented system at all, plus the primary flow and return to cylinder are piping hot & are not mixing with hot water in the cylinder.
Also, With the emersion it is not heating the water enough, the size of the hot water cylinder is 36x16. At full capacity you only get 4 mins out of 2 hours of the emersion being on.
I have tried everything please help........
