Thermal Store efficiency

    Hi Folks, I had posted thread in the p&h section but didn't get much of a response.
    I was hoping to get some feedback from anyone with experience either installing or living in a house with a Thermal store in operation.
    We had intended to install a 750 Ltr thermal store from a well known Finnish company, which we could integrate our solar, back boiler stove and oil.
    We have recently heard however that the DHW heat exchange coil within the tank may not be efficient enough in bringing up our DHW temp to meet our demand and it was suggested to us to have a look at a tank-in-tank store which could offer us a better return on DHW.
    So if anyone has any experience with either tank or indeed another thermal store I would really like to hear about it before we make our decision either way.

    How are you getting the WBS to heat the TS?

    The stove itself is a 10kw pressurised stove from Germany and will be linked directly into the upper part of the tank. I do know that many plumbers we have spoken to are uncomfortable/unfamiliar with such a system even though the stove setup will have a quench coil which will prevent the water in the boiler from boiling.

    I have a thermal store 750ltr fed by solar and oil boiler, three power showers supplied.Installed 2009, It gives enough from the solar alone in winter when sun shines for dhw.
    temps in upper part of store around 45/50 ,low 30s in bottom adequate for plenty of showering etc.
    I only bring the oil on for space heating if required . I have a stand alone stove not connected to system .
