Help with installation / diagram

Former Community Member
Former Community Member
Hi,


I am after some help with a heated windows installation / diagram - grateful for any input.

Unfortunately, the company supplying the installion went bust and I have been left with a system that doesn't  work (incorrectly designed).

We had a local electrician do the first fix wiring based on the diagrams but he says what has been sent won't work in it's current state and he doesn't have the relevant expertise to adjust it.

We live in a rural area and electricians are not that common especially for something as complex as this.

Rather than post up the diagrams and go into too much detail initially, I just wanted to know if this is a place to ask for advice and if not could anyone point me in the right direction. e.g contact details for an electrical engineer.


Thanks.

    I re-iterate the papers and the kit do not match, we should not trust either at this stage. It may be that the no of SSRs was higher as the intention was to use some sort of always-on central 3 phase transformer, and secondary side switching, and given the no, of disparate secondary voltages involved, then there have to be that many switches,

    Clearly, like the rest of it, for a UK single phase supply, that is not going to work.

    I agree, if that TX is rated at 250watts, it is most use as a doorstop, and if there really are 10kW of windows to heat then the total kVA of transformer that is really required is going to have to match!

    Now with a true iron core transformer, (not some electrronic voltage reducer like with the halogen lamps) that  will be quite a serious weight - think 2 man lift at least, (or more sensibly a few less serious weights, of at least one per window group of a given voltage) 

    For comparison,  a 3kW site transformer (the yellow 110V sort) is only really painfully "luggable", rather than easily "portable" and these windows  will need 3 to 4 times that at least (and those site transformers are only rated at 3kW for short duration, continuous use they are  only good for something  more like 2kVA).


    It pains me to say it, but are you looking at legal routes/insurance to recover any of the loss on this ?
