The builder ran off... 

Friend of mine spent 14 years happily turning up and down his heating wall thermostat according to the seasons in a new build. When he got a new extension built, the electrician called him over said how have you found the thermostat, he said grand, electrician said thats strange because its not connected to anything. No wires anywhere.

Builders should stick to bricks and cement. You was in a dificult position trying to help the lady out who had a shit job done. Well done Del

You should be able to do a resistance test on the mat connections to see if there is a circuit. The set up is weird, why the fused switch near the skirting board and why no warranty?

Del and @mainly_electrical are the best electrical content, they always give us faults, real life issues.. then resolve them. Majority UTube sparks, want to show us new install, to show off their brand. Faults / repair over shiny new installs any day the week 👍🏻👍🏻

Great video dell .love the channel 👏👏👏

Well when they buy it there’s a resistance on the box u supposed check with there meter

She’ll be like a cat on a hot tin roof 😂

I would have blank plated on the outside of the bathroom and fitted it on the inside, otherwise the room is going to be constantly calling for heat if it’s only running on air temp.

Yes this now has a good chance of overheating the floor as it tries to get to setpoint in another room. Also please do an isolation test and make sure its behind an RCD. The manual also specifies this.

personally would have tested mat resistance was ok first before doing anything to save time. seems it was ok though luckily

I've got a makita multi tool, Jig saw and torch all 18v and 4 or 5 batteries in the garage if you would like them.

This is the best electrical channel on you tube ,i love the way Delroy explains things in a no nonsense way, keep up the good work Delroy 😊

“The client has been in with her bare feet and it’s getting warm, that’s cool” 😂😂😂

A very crude fix as long as the customer knows that the bathroom floor temperature will only get as warm as the area the sensor is located.

Should Name and shame the cowboy builders

Bathroom fitter laughing all the way to the next job. I had a ceiling extractor above shower in brand new bathroom. Went straight into the loft insulation, no ducting at all! That's the sort of quality workmanship you'll get from a Bathstore fitter. Mould everywhere in the loft all timbers white with mould. Horrendous.

Couldn’t the external sensor have been put in a small enclosure on the other side of the wall (in the room with the heating mat)?

That is going to be very expensive to operate. Always on until the central heating fires up. A floor tile really needs to be lifted and a sensor installed.

Del....one can get really good over time , making good , around boxes ..etc...you get a feel for it..../ knew a joiner once , could run skim like a pro..

What we're the IR and resistance results?

Hammer time! :)

Surely you test it’s working before you start telling the customer what you’re doing and start chasing walls out. 🙈

I've seen some shoddy workmanship before but this is among the top 10. I found an outlet once where the screw wasn't done up at all. it's like they backed it right the way out to insert the wire and never tightened it at all. Imagine finding that when a customer calls you in to fix a faulty socket that "works intermittently."

if sensor not in floor pointless having it

Wouldn’t want that electric bill🤪

No school like the old school

Nice job del shame there was no floor sensor but you done the best you can. I had the same thoughts the other day with a scolmore click switched fused spur on a boiler, the fuse carrier is too close to the switch so you have to switch it on to extract the fuse. Crazy

WOW UR ROUGH AS WITH UR CHASES 😂😂😂

Well done Delroy. Great to see a pro at it. If you checked the resistance on the mat you know if the element is good. Rescued a crap job. The air sensor better than nothing but as you said not ideal.

Bet the downlights are a laugh

Good work Del. But whoever did the skimming job made a right mess of it. On the skirting, on the frame and on the wallpaper. I used to work with a local electrician doing that very job and took pride in making it good and clean as possible, ready to decorate. Anyway, love your video's Del. Keep up the great work.

Shouldn't have started without IR / continuity tests.

Good job neet also

Builders are cow boy electrician's should be a Criminal offense If not. Qualified? Or competent Well done great job you did 😊.

Five quotes and went with the cheapest. No sympathy.

“Teaching your granny how to suck eggs” is his only response to incompetence I’m afraid. Clearly no idea

hmmmmmmm no your work is nice, but it's a bad job without the sensor, and that plastering is worse than mine - that's bad

Not all heroes wear capes! Good work Sir

Thanks for sharing Del. Keep up the good work

Great Job Del 👍🏻

Get the client to report the builder to trading standards and take the builder to a small claims court. Then that will pay for your work 👍

Great content Deltoy as always.
