Thermal stores and private water supplies.

[Jonsey]

Hi, we want to install a thermal store to link a Rayburn 355, conventional oil boiler (as backup) and solar. Our main hurdle is all the thermal stores we have found require mains cold water supply for dhw. Whilst there is reasonable pressure from the pumped water supply, it is unlikely to be able to cope with providing direct hot and cold water at the same time. Any suggestions?

Presumably your pumped water supply goes direct to a storage tank?
And you have adequate supplies of hot and cold water currently?

One option would be to fit a boost pump on the supply to the thermal store for the DHW.

Thanks for the reply, current supply is normally sufficient, although I did max out recently (I had to turn everything on to flush out a septic tank) presumably upgrading / putting in a larger or additional storage loft tank would solve this?
