Gents As some of you may have noted, I have another thread running at the moment about my central heating. Hopefully I'll soon get the bottom of the problem and be able to find a cure. The reason for this thread is that I'd really like to buy a book that would enable me to understand how...

I've recently built an extension and added just two radiators upstairs which was reasonably easy to do. However, since we've had this spell of bad weather the radiators downstairs didn't really get warm enough and I immediately suspected that I needed to balance all the radiators. Now, I...

The main in our house comes in at the kitchen, and at the moment we're having a new kitchen installed. As all the units are out, I've noticed that the cold water main gets absolutely covered in condensation before it disappears up towards the loft. Is there anything I can wrap around the...

I've got a Potterton 60 which has pretty much had it. Our house has been extended quite extensively, so it's probably about time we had a new boiler anyway. My friend has a Potterton Supima 100L which he's just had removed from his house before it's refurbished. So, my questions are… 1...

My Potterton Suprima has failed, and going by what I've read from past posts on this and other forums, I think the fault lies with the Air Pressure Switch. I have now removed the switch. What's the best way of testing it? Is it possible to connect together the two wires from the switch? If...

Potterton Suprima 60 Got up this morning - no central heating for hot water, so opened up the flap on the boiler and pressed the re-set button and it went to solid red. When I adjusted the central heating timer so it was calling for heat, the boiler clicked, then an internal fan started...

I'm about to start wiring up my own alarm system. What does End of Line mean? My panel gives 8 zones as 4 wire. 16 zones as 2 wire. And also 16 zones as 2 wire EOL. What's the difference. Sorry for the question, but I'm confused?

I'm putting a couple of new PIRs on our system. At the control box end, the existing wiring has the standard 6-core cables, but it looks as though there's three pairs which have been 'twisted' together. I want to follow this look through to the new cabling that I'm going to put in. How...

I've got to move one of our PIRs and unfortunately the distance is a bit further, so I've got to join a bit of wire in, as it's not possible to replace the whole length. What's the best and most reliable way of joining two lengths of alarm cable? Is it to solder them together, or just to...

A friend of mine has a conventional gravity fed central heating system. Potterton Kingfisher floor standing boiler, hot water cylinder, expansion tank in loft etc. There's a problem at the moment whereby when the domestic hot water is on by itself, everything is fine. However, when he...

We have a 'normal' system. Cold water and expansion tank in the loft. Hot water cylinder in the airing cupboard. In the airing cupboard with have a three port motorised valve and central heating pump. Downstairs we have a Potterton Suprima 60 and time clock, and a thermostat in the living...

We have a Potterton Suprima 60 which has had the usual PCB replacement a while ago, but it's now started to make a strange noise (sounds like some sort of internal pump or fan). Rather than just spending more money on it, I think it'd be better to go down the new boiler route (I think it's...

Well, following the mountain of trouble we had with our old Menvier alarm, we decided to take the plunge and install a brand new system. We used to have a Gardiner alarm at our old house, so decided to go for one of these, as they seem pretty easy to use and configure etc. The old Menvier...

Got a Menvier TS690 system installed at home. Great panel - never had any problems. Zones are as follows: 1. Front Door 2. Hallway 3. Study 4. Kitchen 5. Family Room 6. Lounge 7. Garage 8. Landing 9. Master Bedroom 10. Panic Buttons Part Set A is the one we use at night, and...

My mother has recently decorated her bedroom and decided that she wanted a new radiator (one of the new convector types), so I drained down the system, removed the old rad, fitted the new one (including a new thermostatic valve and lockshield). I then re-filled the system (expansion tank in...

Am putting in a new bathroom for my elderly parents, and have stripped the old bathroom back to nothing, and am planning to replace all the waste and copper, as some of it is imperial rather than metric, so I thought it better to start from scratch. The one job I need to start on is the soil...

Administrators of the forum, please feel free to move this thread into a more suitable category if there is one, as I couldn't find one. We've recently done a ton of work in our lounge, and one of the things I wanted to do was install a system that would pump the Sky+, UHF, VHF and DAB...

I've been reliably informed that somewhere on this forum is a wiring diagram on how to install resistors on PIRs. I've looked, then looked again, and looked again, but can't find it anywhere. Has anyone got any idea where I can find it?

My mother a VERY old system installed at her house, that no longer works, so rather than spending money on fixing up the old system, she has decided to get a new system. I have an old Gardtec 816 control box and remote keypad that was removed from our house when we moved in, and I've been...

My parents had an alarm system installed in 1990 (I think). A few months ago, there was a powercut and the internal battery was flat, so they lost their programmed code. We have since replaced the internal battery, so we'd now like to re-programme their code. It has revered back to the...
