I have a new build house with pumps on both the C/H and DWH. The DHW pump only runs when the hot water is being heated via the timer, which is fine. Recently the hot water flow in the upstairs taps is very slow when the taps are opened - this during the 'timed period' but does improve on...

I have a seized valve on my c/h pressure vessel. Do I need to drain the system to replace the valve? Thanks

My house has underfloor (u/f) heating on the ground floor and rads on the first floor. Each underfloor zone has a separate Heatmiser WiFi thermostat, the upstairs rads have a single WiFi thermostat and the towel rails have a separate WiFi stat. The Domestic hot water has a separate WiFi stat...

I am struggling to remove a downlighter - see photos. I can pull the unit away from the ceiling but I cannot see how to release the retaining clips. The clips seem to have some plastic lugs which are preventing the clips from being pulled clear. I would be grateful for any advice.

Internal conservatory blinds presumably reflect heat back onto the window? If so is there a risk that the double glazing will be damaged by excessive heat? I ask because although external blinds would stop the sun from penetrating but they would be unsightly and very costly.

I need to clean moss from the jointing compound between a large area of paving which is comprised of various sized slabs so there aren't long straight runs of joints. I've removed some moss with a stiff brush but it would be hard work to do it all manually. I'm thinking about an electric joint...

I have a large area of paving that was laid 2 years ago. The builder used joint compound, which looks great, but it doesn't seem to be as tough as I expected and there are some joints that have small sections that need re-pointing. I'm okay to do the job but I only need a very small amount of...

I have two sets of downlighters in my kitchen. There is a two way switch for one set and a one way switch for the other set. I would like to convert both sets to two way switching. I believe I could wire both sets of lights to the existing two way switch but I don't always want both sets on...

I want to install some grab handles on the tiled wall above my bath. The wall is stud partition and it's unlikely a stud or nogging will be in the right place to screw into. Would hollow wall anchors work?

I would like to build a large 5m x 0.3m oak sleeper trough on my brick pavior driveway. I have in mind to line the trough with weed membrane to stop soil leaching onto the driveway. Would this be effective? I've also thought of removing a few of the paviors under the trough for drainage...

Lighting Woodburner I've recently moved from a house with a Jotul woodburner which was easy to light using newspaper and kindling. The stove had a traditional grate with an ashtray underneath so to get the fire going I would open the ashtray door slightly which would produce a great draft...

I have a new Glow worm Energy7 18s system boiler. I would like to de-activate the pre-heat mode by selecting the Eco mode but pressing the + and - buttons for 5 seconds does nothing. I believe a link on the PCB should have been removed during commissioning? How can I check whether this has...

I have a new build house with a Glow worm Energy7 18s -A boiler running g a pressurised system with a domestic hot water tank i.e it is not a combi boiler. The boiler keeps firing occasionally when the timer is off and I believe the preheat option, which should only be enabled for a combi...

I have recently moved to a new build house which has a Glow worm Energy7 18S -A boiler and Neostat room stats connected to a Neostat hub; there is a hot water cylinder on the frst floor. The boiler supplies underfloor heating on the ground floor, radiators on the first floor and hot water...

I want to replace a conventional single light switch and create 2 way switching using Quietic grid switches for compatible appearance with other adjacent switches. How can I hide the receiver? Is it possible to recess the receiver into a dot and dab wall?

I have some UltraTile ProRapid RS Rapid adhesive. Can I use it on XPS insulation boards? The information on the pack doesn't say whether it's suitable i.e. whether it will adhere to polystyrene. I know Soudal make an adhesive specifically for polystyrene boards but there's nothing to indicate...

I am laying some insulation boards then a heat mat followed by a latex screed then Amtico flooring. The Heatmiser room stat has a heat probe which it is recommended should be located as close the centre of the room as possible but I understand the probe should not cross the heat map wires so...

I have a new conservatory nearing completion and I am going to have an underfloor electric heat mat installed. The floor of the conservatory currently consists of a concrete raft, then Kingspan insulation (not sure of its thickness but I would say about 75mm), then a 75mm cement screed. Is it...

I moved into a new build detached property in January. Our neighbour's garden is a meter or so higher than our garden and is separated by a brick retaining wall. I have noticed that the bottom of the wall is permanently damp even though there has been no rain for weeks now. The soil is clay...

I have recently moved to a new build house with underfloor heating on the ground floor and radiators on the first floor. The bedroom rads have a timer and there is a separate timer for the towel rails. The UF heating is controlled by individual Heatmiser V2 stats which are connected to a...
