Thanks for that. I didn't realise that a combi could feed just one HW outlet. What would happen if (as in my case) all 7 outlets connected to the combi were opened? Would it damage the boiler or just result in low pressure (one seventh of the total) hot water being released? Thanks for the...

Wow! I didn't expect that answer. If it is a common problem, shouldn't MCBs be designed with higher tolerances? As for spotlights (in their kitchen), they are the worst and since the last time one of those bulbs popped and launched itself across the room, my mother is reluctant to use them...

My parents' house is 25 years old and has never had an electrical problem. Recently a new 'fusebox' (or whatever the pro term is) was fitted, containing trip switches (rather than fuse wire as in the old one). Since the fitting bulbs on the downstairs ring pop more frequently and when a bulb...

Is there any point to have the system flushed and fresh inhibitors introduced at a total cost of £220? I guess what I'm really asking is if it is worth getting my plastic piping (responsible for the build up of the muck in the system I'm told) replaced with copper? If this is done, how big a...

My current CH-HW system is 10 years old. The boiler works fine but the pipes and radiators are full of muck. The boiler is in a daft place in the kitchen (soon to be refitted), occupying much needed wall space. The house is a 3 bed semi with 10 radiators, 1 bath, 2 showers, 4 sinks with HW...

Thanks for that. In my loft, in addition to the joists there are two beams (on top of the joists) running perpendicularly. What are they for? Thanks.

Please help if you can: If I wish to board out my loft for use as storage do I need to strengthen the joists (currently 10 cm deep - 4x2)? If I wish to convert my loft into a habitable area how do I go about strengthening the joists? Is laying some extra 3x2 perpendicular to the existing...

Thanks for the comments. I've noticed that some rooms are wired differently from others. Some are wired as originally described (junction box - light 2 - light 2 - ... light 6) but two rooms appear to be wired in a mini-ring i.e. junction box - light 1 - light 2 - ... - light 6 - junction box...

Thanks for the help. A mix of 35s and 50s it is.

The title says it all. I cannot control the hot water system (boiler and cylinder type) without the central heating coming on (and vice versa). I assume this is due to a seized (due to sludge) electric splitter valve (sorry but I don't know the correct term). If I wanted to replace it would I...

Our new house is full of delights. One of them is the fact that the radiators on the back wall of the house work perfectly, but those at the front barely get warm. Perhaps the geography is just coincidence. 1) I assume the problem is due to sludge, but why would sludge build up in some...

Hi. I'm just a simple diyer, but sawing the bottom of the door posts is the way I've always done it. I'm not a fan of trim. I think it gives a far better look if the flooring slides underneath the doorposts (try to keep the gap as small as you can though).

I read somewhere in this forum (but can't find it now) about insulating between the rafters of the roof. 1) Is there a required distance between the roof felt and the insulation material? 2) What is the best material to use and how do you get it to stay up? 3) Is it bad to insulate in the...

We've recently moved into our new (to us) house and I am looking to insulate and board the loft (and have posted separately on this matter). I have just noticed that there is a total of 26 halogen spotlamps upstairs and each one is rated 50W. That's a total of 1300W if all are switch on...

Hi. I have recessed lights in the ceiling upstairs and wish to insulate and board out the loft for storage. The 50W halogen bulbs get quite hot and I'm wondering about the distance required between the light and any insulation (fibreglass) I install e.g. is a 10 cm radius sensible? Also, what...
