Replacing Underfloor Heating With Wall Heaters?

[sl1210]

Hi guys,

Went to see a job yesterday where the whole flat has underfloor heating, which has packed up and now they want a quote to replace this system with electric wall hung heaters. Because of the size of the property I reckon it will need at least 5 heaters. The property currently has 2 ring circuits, 1 for the kitchen/dining area and 1 for the rest of the flat.

1 of the five heaters I can spur of the kitchen ring, but not sure where to take the supply for the other 4 as I'm sure the load would be too much to have 4 electric heaters on the other 32a ring, with each one spurred off the nearest available socket.

Now the current underfloor heating seems to spread on 3 individual circuits in the consumer unit on 16a mcbs, but the supply doesn't seem to go to spurs for each thermostat, I think it goes straight to the stats. There are currently 5 underfloor heating stats. I think they are all connected to some kind of relay in the consumer unit, which is always making some sort of clicking noise when I tried testing the underfloor heating.

Is there any way possible to put these on the ring, or would I need to break down the load with wherever these 16a feeds are going too.

Cheers

Unusual for underfloor elements to go open circuit.
Have your tests confirmed that they have?

i think someone else has already been in and condemned it and given them a quote to replace the system. i think they just want another quote from me.

i was only there briefly last night, to be honest i never done any resistance tests. i just went round and set all the stats on to 35 degrees and not one of the floors heated up. theres definitely a problem somewhere. i don't think they want to start lifting all the wooden flooring up, so they just want to replace the system.

strange that all 5 stats are not working???

i would do some more investigation into what is wrong with the u/f system. can't be that 5 elements or 5 stats have all failed.

Creda heaters are good you can wire them all back to a small panel and fit room statts

yes i agree it needs further investigation and will strongly recommend this. but they have asked for a quote and so i'm looking at possible alternatives. ideally i would like to try to use the existing power supplies, so that i don't have to run dreaded trunking all over the flat back to the consumer unit

Do your research mate the last thing you want is to suggest some electric heating that is too expensive to switch on

I would be having a real close look at that

You say it probably requires 5 "heaters" - I guess then that you are not talking about storage heaters! I would question using convector heaters as a replacement as the operating costs are likely to be prohibitive. Check if you can use any of the u/floor radial circuits as supplies and look at storage heaters; these will already presumably be on a different tarriff.


I have also seen a German manufactured infra-red heating system which can use a domestic tarriff; can't recall the name at the mo, but will look it up and post the name if I find it.
