i will invest in a meter and will check the power from all the live wires in all modes, if these are ok i will have a look at reinstalling the wire link though i think i will need more info as to where to find it or what it looks like and maybe how you reinstall it as i have never seen the...

Thanks all for taking an interest, i agree about not paying if not fixed but after spending 2 hours trying to find the problem and finding out what does work has helped me get to grips with what i can do to find the problem my self, i did not think £20 was bad for a call out. Thanks for your...

ive no intension of cobbling them together, it would help if i can get some answers. The reason i am looking at a wood burner is because gas is not cheap any more and i can get wood at a good price.

Hi, im looking to buy a wood burning stove with a boiler but have some questions that i need answering. The size of my room (18'x11'x8') suggests i need about a 4kw output but the with 9 radiators it works out at 10-15 kw,if i got a 10kw, would this be too hot for the room? Do these wood...

Hi and thanks for all the details, i have had another engineer out, 3rd one and again he cannot find out what is wrong, he says everything appears to be working but the boileris either not coming on when ask by CH or it comes on then turns off after about 30 seconds, im not paying for another so...

Hi, im looking for a double pull light switch for my bathroom. Im not sure if this is what it is called, i need a pull switch to firstly turn on the light, then when pulled again to turn on the fan, or its just one pull but it depends on how far you pull as to whether or not they both come on...
