    Paul,

    You have hit the nail on the head. One installer (AshadeGreener) fitted a seperate fuseboard and then linked it to the grid via new meter tails and a henley block(mother's house). When i had my solar panels fitted the installers (Homesun) they went directly into my existing fuseboard. (this was quickly changed) Both methods are correct according to th IEE regs.

    This forum is about using the surplus available power and using it in an immersion heater. I have just elected to keep my existing immersion heater 3Kw and use a off the shelf controller to run it.
    A 2.5 Kw controller is as little as £50
    Plc is about £100
    CT's are about £70 Pair (probably find cheaper) need them to be 4 - 20ma or 0 - 10v Dc output

    Dont suppose anyone know how i can reduce this cost (CT's) ??

    I'm pleased you have located a supplier of a 1 kW immersion heater.
    I wish to load up[ my solar panels in the same way. Could you please let me know which company supplies the 1 kW heaters?

    hope you dont mind me saying but why pay £83 for a 1 kw immersion heater. I've found a thyristor controller for about £40 and you keep your existing 3 Kw immersion, just need a controller to run it, thats the easy bit.
    Use all spare electric up to 2.5 Kw

    Are you using a home built Phase Angle Controller or a ready made, off the shelf solution

    Paul Hi

    I'm using an off the shelf unit. It's tried and tested and resonable cheap (2.5 Kw).

    There are two units i've considered

    0 Kw - 2.5 Kw and the other 0 Kw - 3 Kw

    Both are controlled via a 0 - 10 V DC signal and the plc i am using does that fine.

    There is a dead band at the lower end but never the less any thing over 500w is used. so if there is 1.75 kw spare, it is used. The unit switches off the immersion, or any other device if any power is taken from the grid. also switches itself back on when there is spare power.

    Andy
