Hi all, My Baxi 836 boiler relatively new works all fine with the nest thermostat for heating using opentherm but when it comes to regulating the temperature of the hot water it will always go to 68 degrees (assume max) rather than the temp set from the nest. I assume this is something to do...

Hi all, Is there any regs on how close I'm allowed to fit spotlights to a steel structural beam? TIA

Hi all, I need to fix fireboard around the steel beam, first of all I need to attach noggins. I've been told from various tradesman that were doing other jobs in the property at the time they mechanically fix noggins however another said to just to knock them in and not attach to the steel...

Hi all, My return brick works is slim up to my bi fold to prevent a step in. This proves a little difficult there is a wind post in the corner. How would i insulate this void but for then plasterboard to be dot and dab over the top. There is nothing for the plasterboard to hang onto. I can...

Hi, I'm wanting to fit plaster in the wall lights, before dot and dabbing. These require some space behind the 12.5mm plasterboard, essentially and for ease the removal of a whole brick. I'm looking at x4 plaster in lights, however one of them would be right over the middle of a steel beam -...

Hi, I'm new to dot and dabbing and admittedly struggling, I've only accomplished three boards and cannot seem to get them perfect, will the skim coat go over these boards or will they require correcting? There is a couple of mm high and low points between them.. Thanks

Hi, I'm running 15mm PEX pipe under the screed circa 35-40mm in depth, the pipes are laid on a concrete sub base that has 150mm insulation in. My question is what is the best insulation to wrap the pipes in? I'm currently using wool, but is there anything with more performance? Should it even...

Something like this: https://www.mlaccessories.co.uk/products/4382281/datasheet.html Thoughts on them, are they easy to fit etc?

Hi all, Built extension that includes an outside cavity wall now inside. I'd like to add a recessed box into the cavity first skin of bricks not blocks, to aid hiding of TV cables eventually - It's quite small needs two bricks horizontal by say 6 bricks vertically, will this impact the...

Hi all, Are aluminum rads worth the hype? Looking at a high output but they're obviously more expensive. Looking at the following...

Hi, Looking to bend hep20 pipe what's the max bend radius? Is it possible to get close to 90 degrees? Thanks

Hi, I need to run some new copper central heating pipe 15mm from the manifold to new radiators in an extension, the run to the first rad could be up to 8m and to the next possibly 12m - is it too far away? What is the longest the combi boiler could push around the system without degrading...

Hi, I'm in the process of adding plasterboard to a ceiling before a skim coat. How important is it to get these flush? there is a small gap of maybe 3mm between a couple of these? Also when jointing two plasterboards some of the boards cannot be fixed with screws along the joint line due to...

Hi, On building an extension, I opted for cold roof and in order to gain max thermal performance decided to not run electrics for spotlights. Now I need to add lighting such as LED track lights, is it possible to run the cable ontop of the celoxte under/in the plasterboard? The plasterboard is...

HI, Has anyone used a recessed LED light strip? I'm currently selecting lighting for an area in a kitchen - its for an extension and a pitched roof with PIR. Instead of the usual LED spotlights I'd rather not punch into the PIR and ensure airtightness and maximum insulation performance. My...

Hi, I'm need to move my circuit board that supplies the house over to another wall - it needs moving maybe 30cm no more. My question is, can the electrician lengthen the cables that are already in situ or would this need a rewire? Thanks

HI, In the process of bricking up the internal wall for the cavity gap from old (75mm cavity) to new (100mm cavity extension), what's the best approach here? Step/stagger the bricks in straight whilst following either the 75mm or 100mm cavity or slightly angle the blocks so that they align with...

Hi all, Builder has set padstones tight up under the steel, it's been 3-4 days and where it's dried out the padstone now has a gap between the steel and the pad of about 1mm or so, what's the best mix to be using to get this set back right without it dropping. Thanks

Hi all, On my struc calcs it mentions either bolting or welding two steels together 3000mm UC 152x152 30 x2 - however there is no mention of the space between the holes, the spacer to use or the bolts. Anyone have a standard formula? BC had passed these calcs without any questions. Thanks
