I was doing some work at a customer's house today and she asked me to program her underfloor heating as she hadn't got around to it. (I didn't fit the UFH)

I switched the stat on (warmup t-stat), set the time, put the other info in etc. As soon as I asked it to start warming up it kicked in and blew the fuse.

Has anybody come across this before or know why the fuse would blow?

Hope the cable under the tiles hasnt been cut, has she had it working before?

No it's only just been wired up. It has been tested for continuity though.

This could be anything but certainly is a problem. Warmup PLC have a tehnical team tat crawl around the country fixing Warmup underfloor heating systems so my advice would be to tell Mrs Customer to give Warmup a call and get their tech-guys out to check the system and obviously not to use it before they check it.

It could be a damage in the cable... if it is you can fix it with little effort. It could be a power-related problem or it could just be a faulty stat.

My advice to others in the future. Use Electric Underfloor Heating Systems - Varme UK (buy from Electric Underfloor Heating UK DIY | Homepage for Handyheat or Ambient Underfloor Heating ) or Flexel Heating Solutions - Under Floor and Ceiling Heating Solutions (buy from Online Electric Underfloor Heating Specialists or underfloor heating UK). And on the thermstat front Heastmiser or Aube seem to be the two best in the maret at the current time.
