If the your resistance reading is rising it suggests something copulative on the circuit. i.e. something still plunged in or a fix appliance Fused spear? If you bypass this cable you will leave whatever it is disconnected. My main point: If the cabling is damaged by damp or ingress causing...

Is the rating on the rcd in the other unit 100mA trip? If so you could fit a 3 phase 30mA RCD to the main incoming tails. or swop the main switch in the bill board for 30mA RCD from EATON/MEM. The armored cables aren't made off well if the armorings are not connected properly you may...

The element may have gone, coursing a earth fault. But it could be the control wiring. Disconnect the heating element the two wires and use a meeter to measure the resitance between the two ends of the element, 2Kw should read about 26 ohm if it a lot hire it need replacing 10- 25 quid...

I take it the RCD is the main switch (switches everything off). An imbalance in the current between L N is what courses RCDs to trip (earth leakage). This could be a fault between L and earth or even N and Earth!! There are lots of coses:- Water ingress Faulty appliances (usually...

I have a L reg 205. It has had a knocking in the steering weel for 7 month. I now have a flat spot on the front tire. swaped for the spare and noticed the pads seem to touch the disc in places.

Yes. your wright. But 3/8 is the internal diameter of the pipe the hole.. outside diameter is about 14 mm. The pipe fits quite snug inside a 15mm pipe, would it be ok to do this and run some solder round?

i know 1/2 inch pipe will just fit int a 15mm fitting. But it's not 1/2 inch pipe. imperial pipe is mesured on the internal bore. this has a bore of 3/8 inch. It will not fit 10mm or 12mm fittings.

10mm is way too small the outside diamiter is about 13-14 mm

I have come across some old imperial copper pipe in my house. The size is 3/8 inch internal diameter. How do I join this to a 15mm?

I would make sure an RCD or RCBO are used to pick up any earth faults. As earth spikes readings will vary depending on how wet the ground is and come summers! :)

There will be 6 rads and a bath. The boiler will be in an old coal store under the stares the gas meter is about 2 meters from this location. Unknow water pressure.

I am about to have a new heating system installed, and would like advice on boiler size. It will be fitted in a two bedroom house and will need to run a mixer shower. All advice would be much appreciated. Thanks!

If 28kw is min then maybe I should go for the 33kw. Thank for all your advice... :wink:

Could anybody give me some advice? I am planning on getting a Baxi duo tec 24 HE. Would I be able to run a mixer shower off this boiler, or would it be better to get a 28 or 33?
