I have an Elson Sapphire double feed indirect hot water tank and I need to drain down the system to move some radiators.
Would anyone be able to offer any advice as to the correct drain down and refill procedure for this tank?
It is a self contained boxed and insulated unit with a single cold feed cistern for the secondary Domestic Hot Water side, the primary indirect Central Heating feed and expansion tank seems to be internal to the boxed unit and isn't accessible.
From the schematic it looks like it has an internal vessel connected to the indirect coil which I am guessing deals with the Feed and Expansion.
The pipework connections for the tank are cold water feed to cistern, vent pipe from cistern, primary flow to indirect coil, primary return from indirect coil and domestic hot water draw off.
Any advice would be much appreciated!
