Hi there, Planning on creating a vented gravity loop going into a hot water cylinder. The F&E tank is one of these: http://www.polytank.co.uk/polyred.htm It allows for a 22mm Feed and 22mm Expansion pipe to be fitted to the loop. The hot water cylinder has a 28mm coil specifically...

Looking at induction hobs, I'm just trying to figure out what the logic is behind the wiring instructions. (I'm just curious, that's all) Take this one for example, 230V model. http://files.baumatic.com/usermanuals-uk/bhc605%20280212.pdf Page 21-22. 3core x 4mm² (30A rated double pole...

Right, I'm making a room for a boiler + Hot water cylinder etc to sit in in the loft. Only thing left to consider is the ceiling construction for it. It needs to be reasonably resistant incase something goes horribly wrong and something catches fire in there, as there is no "easy" access...

Currently this property is served by a septic tank which gets emptied once in a while, but that's about to change, the run is being diverted to a newly commisioned public sewer sometime next week. At the moment there is a 110 pipe coming out through the founds of the house, into a 110->160...

Another theoretical question I'm wondering about. Say you have a CU with 3 phase incommer. Off that consumer unit you wish to run: One 3 phase MCB for a 32A 5 pin plug Three single phase MCB's for 16A 3 pin plugs Each on a seperate phase. How does the RCD work in that case? Does...

Looking at a Grundfos SP3-50 (Single phase, 1.5Kw Max, 6A, 10Bar Max) I can't for the life of me seem to find a decent controller to go with it for a reasonable price. I'm looking for something like this: http://www.italtecnica.com/index.php?ip=4&cat=1&prd=42 Basically it will be 8m...

Does anyone have any input or suggestions regarding creating a dedicated concrete pad for a washing machine to sit on? The floor itself will be 100mm concrete 100mm insulation 65mm screed with UFH and then tiled. Just sitting here behind my desk having a washing machine on spin-cycle at...

I've been hunting for the answer all over but can't seem to find it. Starting from scratch - redoing floor, room is 3m x 5m currently there's a hole in the ground. Its going to be a livingroom. So in order from top to bottom: Floor covering Screed with UFH pipework (65mm) Insulation...

Say you have a supply rated at 63A coming into a property, directly from the overhead wires. Through the meter - and into the consumer unit. The consumer unit has a 100A rated isolator switch. The load consists of 4 circuits each protected by 16A MCB's, and one circuit protected by a 32A...

Is there a standard for colour coding different ratings, or is it each manufacturer to their own? I'm trying to make some diagrams of a CU and I can't seem to determine which colour goes with what rating. Does anyone know of any standards? Or is it just a case of picking one manufacturer...

Still fully functional.... Main incommer into house, straight to the overhead wires. 3phase + PE-N Aluminium wiring, 63A per phase rating max. 1 phase the insulation is burnt vapourised/missing, 10cm bare wire to terminal. another phase insulation is burnt, 3cm bare. It's only 20 years...

Has anyone got any obvious suggestions as to how this is done? 1. physically cut each block so that a lip fits into the doorframe, then seal with mortar to stop it moving. 2. Drill holes through the frame and anchor it in place using rawl bolts (But you would always see the heads of the...

I'm looking at purchasing a laser level in order to be able to square up new walls and old existing walls (And render) in an old house I am reconstructing. The problem is this, the existing old walls aren't sitting straight on their foundations, the corners in the rooms aren't square...

Just looking at this as an option, existing walls are rather pants, mortar/rubble built, and very cold (Despite being insulated from the outside) I want a nice new (breathable!) inside finish, and attempting to straighten out the existing walls without half the render falling off by mistake...

Most modern stoves have a separate combustion air intake since modern homes are made practically airtight which can create a backdraft. Looking at schemes there are two ways to introduce cold air to your fireplace, one is via a dedicated ventilation channel in your chimney, or via the voids...

Some of you might have seen my project thread/blog. Existing founds are about 50cm deep, built in 1950's, shuttered concrete, with no rebar reinforcement, and its not subsiding and has stood there for over 60 years with no issues. Question is, rather than digging a trench and filling it...

I am looking into an alarm system to put into an old house over the next few months (The property is in Slovakia) We are looking for an unmonitored system which will put granny's mind at rest, being all alone at home and vulnerable etc (You know how it is!) The house is a "bungalow" as...

Hi, I'm looking for a DIN mounted KWH meter to go inside a consumer unit, to measure how many KWH's get used. I've found single pole width meters in both analogue and digital form, but they only go up to 32A. If I had an incomer of 63A and a total maximum load exceeding the 32A rating...

Hypothetical question, trying to understand what would be allowed and what not. Say I have a Metal radiator, fed by 15MM copper pipe, using brass connectors (No plastic anywhere). And it requires bonding in order to comply with XYZ. Are you allowed to just bond all the pipes directly at...

I've got a question. Say you where to create a ring circuit which is 50M long from end to end The cable is 2.5mm2 T&E. Since each socket is being supplied with TWO cables, does that make the current carrying capacity be subject to 5mm2? The max cable load for a single strand of...
