You wait ages for a bus and then 2 come along at once ! It will be 3ft crawl space and yes to store ladders and step and other items that i use once or twice a year. The foundations are one of the main issues i have against the party wall. (the party wall is another garage so they will end...

Hi all. I live a a converted flat which is 1 of 4. All three other flats have a garage and now i would like to build one. I am in the trade but just need some advise. I already have the footprint of the garage which is currently 2 lean too sheds with polycarb roofs. The sheds are 2-3ft...

Don't shoot me down. I only have a multimeter.

Had the chance to check voltage in the main CU and the voltages between N-E is 0 yet when measured at bare wires at the end of the cable run its still 20v N-E got to be something to do with the cable. Next im going to disconnect at the JB inside to the roof where it connects to the...

sorry should have explained it supplies a small garage CU with 2 sockets and 1 light. Firstly i disconnected the 2 MCB's within the garage CU L + N but left the earths connected. It still tripped the MCB. Then i disconnected the live and neutral from the RCD in the garage and left the...

MCB 32a Should of but i didn't measure at CU no. There doesn't seem to be any problems at the CU end just this one MCB but i will check the readings. It doesn't trip when all three are disconnected at the end of the run but the 20volts across N-E seems suspicious to me. thats whats...

the cable run is say 30m of 10mm and the last 10m is of 6mm armored cable so it has 1 join inside. The cable then runs out and under ground for about 2 meters. The armored cable hasn't had any movement or disturbance so it cant be anything to do with that. The little cut/nick was in the...

Hi all. First off i spent a year at collage doing c&g 1360 and 1240. this was over ten years ago so i know basic electric skills but not qualified. i fitted a 10mm cable length probably a 40m run. its been in for 6 years no trouble. Now it keeps tripping. Disconnected the live and...

Yes, thankyou very much, Thats all i needed to know.

I have UFH of area 7m2 as above. I have a circuit with a constant water temp of 65 degrees C the simple question is. What would be the best size heat exchanger to heat to the single UFH circuit ? Regardless of where the heat source is coming from and how its connected.

thanks for your responses its a very long story which i really dont want to go into. I just need to know either what would be the best size heat exchanger for the situation or failing that, how i can work out heat loss from the floor and heating requirements for the floor. Cheers

sorry I'll change that to 65 degrees. I just need to work out the best size for a plate heat exchanger to heat the 7m2 of UFH when the water temp is 65 degrees of another circuit.

I have some UFH which is only 7m2. The UFH heating consists of a suspended wooden floor, 50mm celotex between joists, pex-al-pex 16mm pipe 200mm apart filled with 25mm screed to top of joists. self levelled and then 22mm engineered oak glued down with sika bond. The UFH is a single loop with...
