I'm sorry, but you have confused me. Do you mean separate circuits for each cooking appliance, or one for all four? (You wrote circuit, not circuits). If all the under-worktop appliances were on a 32A ring, does that mean that the maximum combined load could be 7.3kW (32A x 230V)?

In reverse order, we are using 233cm high cupboards on a 240cm wall, so I was planning to mount the uplighters on the cupboards themselves, just behind the cornice (so they will be invisible). The ceiling is vaulted, and slopes at 35 degrees, and is so high at the centre, that it would be...

I'm seeing my electrical contractor tomorrow. He has been rewiring our 'new' 1950s house (for the first time!), and has already renewed all the cabling to the lights and plugs, and will be fitting the consumer unit. That will complete phase 1 of our refurbishment. The next phase is that we...

I'm planning a new CH installation and I have one ground floor room that has a solid floor, and all its walls are traditional brick & plaster. I don't want to run surface mounted pipes to the radiator if I can help it, but I was wondering whether I could fit a radiator on an internal wall, back...

How do you go about deciding how to adjust (if at all) the calculated output requirements for hall and landing radiators when they are connected by an open staircase. As heat rises, I assume that the landing will benefit from heat rising from the hall, and the hall will be colder than it...

Any views on using 22mm PB-1 barrier pipe & polyplumb reducing tees to 15mm to individual rads?

A very different view, here: http://community.screwfix.com/thread/87094?start=0&tstart=0 I'd assumed that with a 'radial' system, I'd end up with a greater length of pipework in total. By running the main circuit along hall & landing from front to back, I can have fairly short 'branches' to...

I'm planning my new CH installation. The house is being extended and the original 1960s DIY single-pipe system has been completely removed, and I'm starting again with a combi-boiler and two-pipe (22mm) feed & return with room stat & TVRs (except in hall with room stat). I have never used it...

I'd prefer to think that I was a realist, rather than a cynic, and I've no expectation that a builder is doing his work for the love of it, or owes me anything. Equally, I don't want to pay a premium, but to get a good job at a fair price. For those builders who want to price me, not the job...

Another way of looking at that is that builders quotations may bear no relation to the real cost of a job (with a decent profit), but are more based on an assessment of what a customer might pay (price the customer, not the job). If the estimating service does use industry standard rate of work...

We are about to undertake a single-story extension project at the side and rear of our house. We have full plans, planning permission and have just made a building control application (Full Plans). We are looking for a builder, but don't really have a benchmark/expectation (other than guesswork)...

Statutory Sick Pay is payable to employees ONLY, and only then after a qualifying period and where earnings are above a threshold (excluding many part-time workers). If you are self-employed and unable to work through sickness or injury you may be able to claim means-tested ESA (Employment and...

That's easy enough for normal radiators, but if I'm going to use a towel radiator on its own, then they inevitably have a limited output. If I go to 1800mm x 600mm (the biggest I can find) the output is still only 2620 BTUs / 768 watts, so the sky's not the limit! I can see why higher output...

That's interesting, but it's a shame it doesn't state the underlying assumptions about different room types: it says 1688 BTUs (494 W) for my bathroom, but that would be only 894/(262) for a bedroom, and somewhere in between for a living room. I leave all my internal doors open, usually, and all...

Isn't it a building regs. requirement to fit a TVR, anyway?

... and good for keeping the bathroom warm too? I've got space for one 600mm wide, and have found one we like that is 1600mm high. The stated output is 1501 BTUs and its a dual fuel rail with a 400W element.

I've looked at a few online BTU calculators to get a feel for the capacity of radiators I require in a new CH installation, but I'm amazed at the variations in results for the same room sizes/assumptions. B&Q's calculator suggested around 1250BTU for my bathroom, but others, twice that! I was...

The ceiling is only 2.5m x 2.6m, so I don't have all that many choices about staggering the boards unless I have more pieces than necessary. I don't want to end up with a 'tiled' effect, with lots of joins that could crack in the future. Ignoring the small sections of exposed joists (where the...

Having taken down a dividing wall between toilet & bathroom (to make one bigger room) I have gaps in the ceilings, with joists showing, and the existing PB also has horrible textured paint on it. I'm going to put new PB sheets (1220 x 900) over the existing ones and then skim, but I'm concerned...

The joists are 6"x2", and notches to take 22mm pipe will have to be around 25mm deep, which is a 1/6h of the depth of the joist, while the guidance suggests that 1/8th is the safe max. These joists only span the landing, not a whole room, so I'm guessing that the remaining 5" will be fine to...
