    Hardiebacker board on concrete subfloor

    @Deluks it is more or less level. That part is fine- that wasn't my question specifically. Perhaps I didn't explain it very well. It just says not to backer board over concrete subfloors but in my case I need to overboard this small section otherwise the only way of levelling the tiles is to...

    Hardiebacker board on concrete subfloor

    Hi all, Bit of an unusual tiling situation. I am laying floor tiles in front of a fireplace surround (which I am also cladding with tiles) and part of the subfloor is floorboards, and the other is concrete as you can see from the photo. The concrete part is the hearth which I have repaired and...

    Annoying shower leak

    If you follow the usual advice of not sealing on the inside of that vertical profile trim, how will it not leak? If as step one you do the sealant between tray and wall, let it set, then install the profile trim- the sharp right angle of the trim at the bottom will disrupt the sealant that you...

    New boiler or not?

    Just a different school of thought I guess and perhaps neither is wrong, as long as there is a strategy to prevent corrosion. I'm not an expert either and hadn't really considered anything other than inhibitor until recently and having done some reading up on it.

    New boiler or not?

    No nothing really- it's just there to get rid of microbubbles so any gas from the vent is barely detectable, or certainly not now that it's been running for a few months since last drain and refill. It seems to be working fine and our system water is very clean. I hardly get anything from our...

    New boiler or not?

    We run our CH system without any inhibitor and use a spirovent to remove air bubbles. You may find this an interesting read about water quality and corrosion etc: https://www.heatgeek.com/articles/articles-home?p=heating-water-treatment-explained-vdi-2035

    floor repair before backer board/tiles

    thank you. No not working. We may get a small bioethanol fireplace to place in the opening in due course but nothing that will really affect the integrity of the surround etc.

    floor repair before backer board/tiles

    thanks. I was going to do that but particularly the section towards the middle needs a fair bit of building up. Can I use tile adhesive do you think to build it up this much? There's no signs of damp at all. I did wonder whether it was a good idea that the joists are effectively running...

    floor repair before backer board/tiles

    Hi all, I'm redoing our old 70s fireplace surround at the moment. Having removed all of the old blocks and hearth tiles I'm going to build a timber frame, clad it in hardiebacker, and I have some tiles to finish it off. At floor level I have some matching 600 x 600 tiles which I will lay just...

    Alcove lighting/LED strip advice

    @ericmark interesting idea. Probably not for me in terms of incorporating built in cupboards as I like the simplicity of our proposed design. Good luck with your project though as and when you start it. Will be making a start on mine next week

    Thanks. Good suggestion with wooden frame.

    Alcove lighting/LED strip advice

    Thanks all for the suggestions. Much appreciated. Good shout. I was going to look at smart lighting options. We have a load of hue stuff so that's the obvious choice. Not sure if they are adjustable length though to fit in that alcove. Will need to check. I was wondering what that socket was...

    Alcove lighting/LED strip advice

    Hi all, I'm renovating a fireplace in our living room as part of a complete refurb. I've attached a photo of what it looks like now, and an AI generated image of what it will roughly look like when done hopefully. It will be clad in tiles with oak shelving: My query is how best to install...

    Heat Pumps and Zones (or not?)

    And I have. As per previous posts I tested it with my boiler and savings- zero. Post #72

    Heat Pumps and Zones (or not?)

    @Ivor Windybottom I don’t understand your maths. Are each of your zones fully insulated and separate entities ie if you are heating one zone, there is no heat loss from that zone into the unheated zone? You also need to consider system volume and flow restrictions. There’s a good chance what...

    Heat Pumps and Zones (or not?)

    not quite. Whilst it is true that the kWh output to the house will invariably need to be slightly higher if maintaining a steady higher temp rather than setbacks, the point is that if you trickle the heat in slowly ie have lower outlet flow temps continuously- efficiency increases. This is why...

    Heat Pumps and Zones (or not?)

    @Ivor Windybottom have you tried it without zoning? How do you know that this approach is saving vast amounts of energy out of interest? Great it works and you are happy with it. That is the main thing obviously.

    Broken tile replacement

    Thanks all. I was considering a sealant bodge but I cannot bring myself to do it :LOL: . I can't actually see any water ingress underneath. @noseall that is my feeling. Looks like a simple repair on the face of it, but then evidently not once I started looking at it properly. I can do lots of...

    Broken tile replacement

    Hi all, I have a broken tile on our roof (attached is a photo- the crack is tricky to spot but it runs alongside the middle ridge bit). Annoyingly it is one of the tiles that is bedded into the wet verge. I have tried to get our roofers round but tbh I think the job is too small so they've...

    News "costly mistake" by prioritising high-tech heat pumps over basic insulation. Really?

    I think you are confusing kwh input of the ashp with the output? A 9kW heat pump isn't equivalent to a 35kW boiler. Both figures relate to the heat output. 9kW is still plenty for most homes and certainly assuming you are referring to heat only/system boilers, a 35, 25, or indeed 20kW boiler...
