Having given some thought to this I have been wondering if the contactor route would be best suited to the project I am currently working on. In the extension I have built I need to have 3 hot water tanks all heated by immersions overnight - but also having a 'daytime boost facility. So...

Sounds a really simple solution - when it's brought to your attention. I seem to remeber doing something similar many years ago at a previous house - but had forgotten all about it. :oops:

I have 3 of these that I bought at £10 each last year at a 'closing down' sale. But you are right, I was considering a two socket system for the utility room for the appliances, but that's not an urgent project so I have not given it thorough consideration yet. By the way - forgive my...

Yes - it is a 'hybrid'. It was the first 'off-peak' supply - and is no longer available for new supplies. The Horstman DX is designed specifically for this type of supply and uses the Off-Peak supply at night, but is also wired to the standard supply to allow use during the day using a...

I have two meters feeding 2 seperate consumer units - the most comon way used in the past when Night Storage radiators were first introduced. Most of these types of installation were ripped out years ago when E7 came in, but our cottage still had it when we bought it 12 years ago - and we...

I have checked the current drawn by the immersion and it appears to be 11.5 amps, so both the DX units are getting warm within their rated current. I guess another call to Horstmann is in order. Nozspark - the 'off-peak' tariff is currently the cheapest way of using our consumption. The...

Thanks Matt. The BX2000 that was being used is only about 2 years old and was used about 3 nights a week for the last 12 -15 months. The second unit I replaced it with is brand new never used. Thats why I was surprised at the severity of the marks. The fuse in the CU is 15a and the BX...

I have the old type of off-peak supply (ie one meter for standard supply and a separate one for off-peak supply overnight.) Originally the off-peak was used for storage heaters which are no longer present, and it is now used soley (at present) for an immersion heater. A year or so ago I...

[/url] Those look very interesting - will investigate further. In the meantime I have spoken to the manufacturer of the showers I linked to earlier and apparently they will work with pressures as low as 0.1 bar. Having looked at the space available more closely I think our tank position...

Can't use electric - 3 of these exceeds the rating of the mains supply to the house if all 3 are on at once. :(

Thanks for that feedback. The weight is no problem as there are some steel RSJ's in the loft space which can be used to support the weight. As far as the pressures are concerned I was interested to see these which, although they don't specify the bar rating, do state that they are suitable...

In our new extension we have 3 bedrooms on the first floor. We want to install en-suite showers in all 3, but our current hot water supply is not man enough to handle them, and we cannot install 3 electic showers as the mains supply will not support all 3 running at once. One solution I have...

Living in a dream world ? hardly. At your guide of £1000 p/m (I assume you mean p/sq.m) per floor you are suggesting you would have quoted me £110,000 - according to you for 12 weeks work. Excluding materials which cost me £20,000 that's the equivalent of £360,000 p.a. Even for 3 guys...

The work has caused no inconvenience at all :) Being stingy has nothing to do with it. I do it because I enjoy it and get satisfaction from it. I am building at my pace to accommodate the other things that I have to do - I also have a life :) Not the objective - although there are so...

I'm building a 2 Storey extension at present - 10m x 5.5m. 3 Beds (all en-suite) on first floor, 2 receptions and new hallway with stairs on ground floor. The shell is up and roof on (cut in, not trussed) and tiled with first floor joists in. Ground floor insulated (walls and floors) and...

Thanks guys. A couple of points and questions. The blocks were wet before the scratch coat, and when the scratch coat dried it was well adhered to the blocks - no problem there. It was then left for 3-4 days before the top coat was applied. I am not sure but I don't think any...

I have just had the front of a new extension rendered and there is a problem with cracks appearing as it cures. The build is using a solid thermal block wall (215mm thick) and an intial scratch coat was applied to the front and sides. This was left to cure for a few days then a top coat...

Thanks again Freddy. These documents can be a bit of heavy going to read and it's really helpful when someone points you to the relevant sections. Thanks for the info on the plasterboard - thats also useful.

Thanks Freddy - I meant part E :oops: I was looking at part L for something else. So from a brief read of this (again) it seems that all I need is a min 100mm mineral wool between joists (and good carpet underlay upstairs for impact noise reduction). Or is that too simplistic? For...

I am building a new extension on my own on building notice. It consists of adding a second storey to an existing single storey extension used as a lounge. The second storey will be for 3 bedrooms. I am currently tiling the roof after Building control inspected and passed the roof...
