    Upgrading analogue thermostat to programostat

    Drayton Digistat + 3 7 Day Programmable Room Thermostat (240 Volts - Mains) looks promising. Not backlit LCD display, but plenty of options. 3 wire installation, so like for like. The Heatmiser needs a 35mm back box according to reviews I read, so this would protrude too far out of the hallway...

    Upgrading analogue thermostat to programostat

    Thanks for all the replies! I enjoy tech, but a smart system is a step too far. I already replaced all the TRVs (4 ended up leaking after 12 years old) and replaced everything with 10mm radiator valves with or without drain. At £1.30 they offered economy over £15 TRVs. The house is a 4 bedroom...

    Rear outside door snags

    The door handle on outside does nothing pulled up or down. It is not connected to anything. A hair brain idea! The key unlocks the bolt and latch when turned. When handle pulled up two metal blades (top and bottom) swing into frame. I asked about the door slab pulling onto the frame before...

    Rear outside door snags

    Yes. The reason for this post is because I have had an employee of the company visit and assess problems. He agreed with issues but, defended the door not fitting frame rubber seal on matching frame to edge of lintel above door. The photo looks better than reality btw.

    Rear outside door snags

    Hi all, I had a company fit a rear composite door and frame to replace a metal clad wood door. The company Allweatherroofline has managed to order the wrong glass, scuff the handle, fit the door so it scuffs, rubs the latch plate, the handle bar is two separate ones so that the outside handle...

    Drainage regs - shared 110mm soil pipe branch with basin, ok?

    Current branch supplied is 92.5 Deg. I had something previously allowing more fall. After drawing different lines on card card using protractor and overlaying on wall, it looks like 112.5 Deg branch is too steep. A 104 Deg branch is on order. Trims at Wakefield could not supply but instead of...

    Drainage regs - shared 110mm soil pipe branch with basin, ok?

    Web search anti vac. They are on bottle trap, u bend about one inch or so high. I guess gurgling will be an issue unless I pipe basin waste into vertical stack vent. I was going for chrome plated brass bottle trap on basin waste (no anti vac).

    Drainage regs - shared 110mm soil pipe branch with basin, ok?

    Thank you. The basin waste shown in photo (just above middle of near horizontal/slightly descending 110 mm wc soil branch) will not use a pan connector branch/junction. The basin joins half way between WC and the stack vent (near horizontal 110 branch, which is about 1m 20cm across in length...

    Drainage regs - shared 110mm soil pipe branch with basin, ok?

    Hello, I am currently replacing the external 110mm soil pipes during a bathroom renovation. Q can I use a strap on boss to connect the basin bathroom waste, 32mm solvent weld, entering 45 degree from vertical , to the 110mm soil WC waste branch via strap on boss, rather than to the vertical...

    fan ducting is not connected (ed.)

    Thanks Ken. Airtec bubble wrap sheet coated in aluminium would be a good choice to wrap and tie wrap the soil pipe however most of the 5m length is in the interfloor space under another floor I am not ripping up (chipboard sheets). Lots of copper pipes near soil pipe and electrical cables. I...

    fan ducting is not connected (ed.)

    Hello all, Whilst gutting bathroom chipboard floor in favour of 18mm plywood that is partially over the utility.room below I have discovered the utility fan duct (50cm) ends near on open soil pipe that is 4 or 5m in length horizontally interfloor. It is not connected. There is a steady draft...

    Shower pump - hot only, unpumped cold tank supply

    The thermostatic valve has been removed x2since the pump was fitted to check for solder flux and lime scale on the inline filters. The lever valves were opened full and the cold consistently had more flow x3than the hot. I wondered if raising the cwt 40cm would be worthwhile. So, holding the...

    Shower pump - hot only, unpumped cold tank supply

    Rereading. It is a coil heating element near to a mains cold supply water pipe passing through hot water cylinder. I'm surprised the water will heat up enough once it flows to shower.

    Shower pump - hot only, unpumped cold tank supply

    Thanks Bernard. Any links to product. Is it basically an unvented cylinder in a vented cylinder. Will this set up need an expansion vessel? What volume is the hot cylinders? Thanks

    Shower pump - hot only, unpumped cold tank supply

    Hi all. I've just signed up and found this forum useful, but having searched exhaustively, I could not find this info. Q. Can I pump just hot water (single impeller pump) and not pump the cold water from the cold water storage tank? Or use two separate pumps? I ask because most of the water...
