    Gledhill's Pulsacoil range has been through several generations but the current version comes in 150, 180 or 210 litre capacities.
    Heating the largest from 30C to 85C would take about 13.5kWh of heat.

    Is this the store  (its water filled - het to 75C nominal but it's just a store - it's not the actual tap water - it uses a heat ex-changer to heat cold mains on demand to c 55C according to flow temp graph )


    Its not a conventional direct (immersion) het tank like I am used to - but in electric homes - is het according to that manual by conventional 3kW heating elements - nominally one e7 with no timer by default in wiring diagram and one peak rate manual switched - or other timed variants.

    There have been many different versions with the pulsacoil name. They can look quite different but are effectively all the same basic principle.

    We could really do with the OP returning to answer some of the questions. Probably not much more we can do until that happens.
