Right, so over the holidays I'm planning to get some of the plumbing ready for the ufh system that will go in soon.

I'm planning to install UFH on the ground floor at my house which currently has a suspended wooden floor. I have around 300mm void under the floorboards with a concrete base. Assuming I go with a 75mm screed to fill, my question is what should I fill it with as I would like to do this myself if...

I currently have a Valliant combi to which I'm going to add UFH system to. So my question is if I wanted an efficient system, would it be better to have an unvented cylinder installed and have the UFH run of that?

Hi there Got a texecom alarm system which has been working fine for several years but lately it keeps going off with the bell tamper as the error. I've taken the bell Bix off the wall to check the tamper switch but this box only has a tamper switch just for the lid, nothing on the back. Any...

Hi guys So I have made an PD application for a loft conversion to my local council recently. Talking to my architect, the one issue I’m going to be faced with is the height. So I’ve agreed to drop the ceilings on the 1st floor down 200mm but with even doing that, I’m still looking at only...

this might be the wrong forum to post this so mods please move if required. so I'm thinking about installing wet under floor heating on the ground floor in my 1920's semi detached house. The original floor is suspended but the new rear extension is solid. So I'm thinking I will just remove the...

Just installed a veritas excel system with Honeywell IS312 pet immune PIR’s as we have a cat. All wired up and working in CCL mode but the pir’s don’t detect much movement when the pet immune feature is enabled. So I was doing a walk test and a couple of the pir’s would hardly detect anything...

I have had this boiler now for around 12 years and it been fine but recently it has started to play up. While the central heating is on and a demand for hot water is called for, once the tap has been closed the red light above the CH temperature dial starts flashing and the heating fails to...

Been having an issue with our heating system for the last 3 weeks. It’s was a brand new system (all pipes& fittings) which was only installed around 4 years ago, we have a Valliant system boiler & unvented tank. Basically when the system comes on in the morning and ONLY in the morning, we get a...

I'm hoping somebody can help me with a problem my friend is having with his heating system - see diagram below. In the last 2yrs I've helped him get his heating working and as the issues seems to be the same, I thought I would put the question out to see if this can be prevented again...

This being a hybrid system, all the detectors and contacts I'm using are wired. I'm using FSL wiring system and I'm using the resistors supplied (2.2K & 4.7k). So the wiring in the PIR's is like this; ___________________4k7 PIR - zone ---------A___/ ____ A ------2k2----T...

I'm helping my brother install this system and so far I'm doing well, I've installed other Scantronic systems before so I'm ok with the terminalogy. Basically he needs 2 programs (part set) options, full set and part set but I'm not seeing the part set programming option! Looking at the admin...
