I have a conventional CWS tank in the loft which feeds a hot water tank in the airing cupboard. The CWS tank has three outlets, 28mm to the hot tank, 22mm to the rest of house cold and 22mm dedicated feed to a shower pump. When I try to drain the tank by shutting off the supply to the ball...

I'm replacing the bell boxes connected to my Scantronic with 2 X Odyssey 1. This is how I think they should be wired: Can anyone confirm this is right? It seems straightforward apart from TR. What does that stand for? Questions: 1. Does the second bell just connect to exactly...

Any tips for neatly fitting window contacts? I have PIRs at the moment but plan to fit contacts as I decorate each room. It's running the wire from the contact to the plaster work, where it will be buried, that would seem to be unavoidable and unsightly. The windows are uPVC double glazed...

I read on a suppliers site that the Texecom Premier24 panel is not compatible with remote keyfobs (using the RadioPlus Intelligent receiver) and I will need the Premier48 panel. Can anyone confirm or deny? Thanks.

I'm looking at getting a couple of Texecom Odyssey boxes and they are configurable as SAB or SCB. Question: Why would I want an SCB, rather than just using two SABs? Is there some advantage of SCB mode? I though using one SAB and one SCB was just for cheapness. Thanks.

I've heard that a common way to bypass an alarm is to fill the bell box with expanding foam. Is there a defence against this apart from putting the boxes in inaccessible positions? Thanks.

After a recent break-in I want to upgrade the Scantronic 9452 alarm system at my house. I have the existing wiring for three PIRs, front door contacts, SAB and SCB, plus remote key pad, but will probably want to add more contacts/sensors wirelessly Can anybody recomend some systems I should...

I want to cut out sections of the flow and return pipes above my boiler so that I can temporarily fit valves to do the mains pressure flushing procedure in the FAQs. I doubt there is any movement in the pipes so to replace the cut out sections, straight compression fittings with no stop in...

I recently moved into a house built in 1994. All the skirtings and architraves are taurus profile. They're a bit of a mess and I tend to think they are not the originals - tons of filler down the back, joints a mess etc I'm considering changing them all and wondering if I should replace...

I need to replace a central heating pump but I'm unsure which one to get. The existing one is British Gas Multihead II. It has "manufactured by Potterton Myson Ltd" written on it and the following table: 3 1800 110 0.48 2 1200 74 0.32 1 700 44 0.19 There is a heading...

I have an indirect, vented HW tank as part of vented CH system which is Y plan. Between the flow and return to the HW tank heating coil there is a pipe Teed directly between them with a gate valve in the middle of it. The pipe looks like it is 10mm. At first I thought this was for...

I've seen a few posts saying to make sure there is a tight fitting lid on the F&E tanks for vented CH systems. What's the purpose of this? I assumed the lid was just a dust cover. Thanks.

I'm planning to build an attached garage to the side of my four bed detached 1990 built house. The house is on an end plot of a close and the side I am planning to build on borders the adjoining street, not the neighbour's house. Construction will be brick and concrete tiles on a pitched roof...

I've a problem with the CH in my house that I moved into five months ago - so not much history on the system. It is open vented, fully pumped Y-Plan, with an Ideal Standard NF50 boiler, 11 rads, HW storage tank. When I moved in the rads were only heating up at erratic times and the HW was...
