    Preliminary advice/information regarding hot water supply

    Thanks for all your input Agile. On further investigation I have come across these which may be suitable as a large breaker tank. I have contacted the manufacturer for confirmation of suitability. Thanks again.

    Preliminary advice/information regarding hot water supply

    Well it looks like the electric showers are out of the equation. (At least using more than one is) I spoke to our Suppliers engineering department who gave me some surprising information. They said that domestic mains supply is only guaranteed to a maximum of 15Kw !!!!!!. (Although by my...

    Preliminary advice/information regarding hot water supply

    Of course it is - :roll: So obvious, but I never thought about it. Thanks for reminding me :oops: I wonder if there are any alternatives to a standard ball cock arrangement that would be suitable. Will have to search around.

    Preliminary advice/information regarding hot water supply

    I measured this at an outside tap which is fitted right next to the incoming main. I did it with and without a sink tap open and although it did drop a bit at the outside tap it wasn't much and the 20ltrs/min was the average. I have a store room attached to the back of the utility room where...

    Preliminary advice/information regarding hot water supply

    Thanks Agile. I based the flow requirements having measured the flow volume of our existing thermostatic shower which is about 6ltrs/min (which we personally find adequate flow for a comfortable shower), with the hot and cold being gravity fed from a tank and cistern with no flow restrictors...

    Preliminary advice/information regarding hot water supply

    Thanks Agile. Interesting suggestion you have made about using a combination of electric and cylinder fed showers, and I will speak to the electricity supplier to check about the supply. Your other comment about the size of cylinder and feed tank are also interesting. Taking my two...

    Preliminary advice/information regarding hot water supply

    Thanks for your concern Agile. 'Workmen' is probably not the right term to use :oops: to relate to the people who would be staying as they could be tradesmen, engineers, project managers etc. However my extension project was planned before the option to offer the B&B option came up, and...

    Preliminary advice/information regarding hot water supply

    Thanks guys. I was thinking the same thing myself when I saw this which is the bigger version of the one suggested. At around the £800 - £900 mark that's not too bad :shock: Choosing from the various makes of this type of cylinder could take some research. However I still have to...

    Preliminary advice/information regarding hot water supply

    We live in an old 3 bed cottage which is currently serviced by a mains water supply from the local farm. It has a bathroom which is located on the ground floor at the rear of the cottage. We have an oil fired boiler which supplies radiators for heating, and an old uninsulated hot water cylinder...

    Waterproof materials

    I have just come across these at a new Toolstation they opened near me. I wonder if these will be good enough to last over the summer. Anyone tried these?

    Waterproof materials

    Thanks Symptoms I looked at quite a few places and they were all a lot more expensive than Northerns. That looks like the way to go. Thanks again.

    Waterproof materials

    They will only be temporary (that's why I want to keep the cost down). The problem is the tarpaulin - the area to be covered is 6.7m x 5.2m, and I haven't come across a suitable tarp that will fit in one piece - and they are so expensive. I guess I could use some polythene DPC sheet (like...

    Waterproof materials

    I have a single storey extension to which I am adding a second storey. To place the joists for the new first floor, I have to remove a few tiles along the ridge of the current roof which means removing rows of some tiles either side of the ridge. I need to temporarily protect (over the...

    Roof design

    OK Deluks here we go. There is an existing single story extension in place and I am extending it to a second floor which will be used as 2 bedrooms with en-suite. The area is 6.9m deep by 5.4m long. The footings are 1m deep solid fill 450mm wide. The walls are 215mm solid aircrete block...

    Roof design

    Thanks noseall, your input is greatly appreciated. One consideration that had crossed my mind was to place an rsj along the centre of the span, supported on the gable wall at one end and bedded into the existing house stone wall at the other. The roof joists could then be supported on that...

    Roof design

    The roof pitch has to be 46 degrees (to match the existing) and it is a clear span width (although there will be a central stud wall in the centre running the full length supported by the first floor joists), but it also has to have a raised tie as the roof plate is going to be lower than the...

    Roof design

    Thanks for your input noseall. The roof I am working with will have a span of 6.9m across, 5.5m long. In your experience what size timber would that require - it has been suggested that an "A" frame of 6" x 2" timber would be the starting point?

    Roof design

    I am not particularly looking to create clear space, but want to work out what would be involved with a cut roof so I can compare the costs of truss vs cut roof - hence my search for information about making a roof on site. I have the time and facility to do a cut roof, but noted with...

    Roof design

    I am self-building a 2 story extension and have everything designed and under control, and am contemplating cutting and building the roof on site. Before deciding I need to do some research to see what might be involved, and wondered if anyone had any pointers to any information I can access...
