Please can someone advise? I am not a heating engineer, but I have recently purchased a vented 250L copper thermal store/heat bank tank (TS). It has a solar coil and all other connections are direct. I have connected an external plate HE for mains water pressure HW side with pump circulating to store. But I need advice for connecting to new oil condensing boiler and CH. The property is a bungalow, store and boiler are next to each other on ground floor. The pipes to radiators go via the loft which is above the height of the TS which, I believe, means I cannot connect the flow/return direct to the TS as I originally planned for an integrated system (should have got a tank with an indirect connection).
The supplier of the TS say the only solution is to have a pressurized CH system (with expansion vessel) heated directly by the boiler and for the boiler to heat the TS via a plate heat exchanger (PHE) with a pump on the boiler side and on the TS side, but are not prepared to provide a diagram of how to do it. So far I have been unsuccessful finding a qualified person locally who fully understands the use of PHEs.
Can anyone provide a diagram or recommend a good book?
I am also concerned about the following:
Will condensing oil boiler run at optimum condensing temperature in this arrangement?
Will boiler need a temperature mixing valve to help set the temperature of the return to around 55 degree C?
Are other items required to be fitted such as automatic air valves, non-return valves etc.?
When it is all connected I intend to employ an OFTEC registered installer to commission the boiler and I have found one who will install the boiler but says he will not try to setup the complete system.
