    Leaking Potterton Promax SL heat exchanger manifold

    So, I thought my boiler was dead, as it had a leak and needs resetting once a day. A plumber who replaced the ignition a few months ago said my exchanger was leaking and would ultimately need replacing so I was getting quotes to swap. but... A different plumber came out today, and said it...

    megaflow, twist or stick

    In short, a 13yr old megaflow (CL210HE) failed a while ago, as it appeared the baffles were breaking down. Megaflow accepted a fault and supplied a new replacement (inc all the fitting kit and MV). So I guess i'm one of the lucky ones... But i've lost confidence in the product, I felt I was...

    Hot/warm deck alternative

    I think i've decided to dig down a little, maybe only 60-80mm, and i'll change the roof and move the insulation inside, making sure to leave a small gap to allow airflow. It's a small compromise that I don't believe will have a huge impact on usability but it will give me the extra head...

    Twintec Vs Dualflo

    I'm in the market for a new water softener and had decided on a Twintec S3 but my boiler has just given up and my plumber said he can supply and fit a Dualflow. I understand they are rebadged Harvey machines but is there anything else to it? I can't seem to find out much about Dualflow and...

    Adjustable joist base options

    very good point about the base, my floor plate will go to the edge, so by the time it's counter battened and clad there will be a nice 50mm overhang (y) I'll cost and weigh up a solid base. I used to dig down and whack 150mm of rubble in before pouring a base, that's my other concern as I...

    Adjustable joist base options

    nope, i'm almost scared to look, I did build a chunky workshop in the height of covid and it was a shock at that point.

    Adjustable joist base options

    I'm not shy of the physical side, two summers ago I shifted 10 tons of gravel down the end of the garden. Just know it's a lot of work and things will get destroyed in the process and mixing that volume of concrete by hand is a wedge. I never really considered the cost of the extra timber for...

    Adjustable joist base options

    @oldbutnotdead Yup, I'm trying to think what I used on my existing office, the floor is super firm and I currently do weights in it, it's just constrained by the 2.5m permitted development height rule. This new gym is going to be part of a planning application as I want it to be 2.9m high to...

    Adjustable joist base options

    Thanks, I had seen these but don't like the thought of them going directly on the ground, feel they could sink over time. Also quite expsnsive once you factor in their brackets (£45) a pillar, so figured what I was proposing was slightly cheaper but more robust.

    Adjustable joist base options

    @oldbutnotdead Thanks for the tips, usually I would prefer a solid slab but pouring this on my own, whilst ferrying stuff 60m to the end of the garden make this a no goer. Pillars like this are easier for me to do a few at a time... I usually put hardcore under a slab, so assumed the same was...

    confusion on garden office

    @^woody^ I could start on the groundworks, then I have the option to get the height I need either via planning permission, or changing the warm deck to a hybrid insulation set-up inside. The latter is less than ideal but it wouldn't render the initial work as useless. With regards to...

    Adjustable joist base options

    Rather than laying a large slab as logistically it's tricky and costly, i'm thinking I can build my garden gym off a series of concrete pillars. I'm the past I've used a cowley to set the heights and have built directly off blocks but this time I would prefer the attached method, especially as...

    confusion on garden office

    @oldbutnotdead Brilliant, I appreciate the quick response, my biggest concern was about the use of non-combustible materials. If this is irrelevant due to it being small, i'll happily crack on with PP. Whilst an inconvenience having to wait, i'll need to spend a few weeks planning the...

    Hot/warm deck alternative

    I kind of already know the answer to this but i'm after a sanity check if someone wouldn't mind assisting? I'm looking to build a garden gym, so insulation (particularly in the summer) is key to a useable space. I've been using my DIY garden office for 10 years which has a warm deck and is...

    confusion on garden office

    Would someone be able to advise on the following: I plan to build a garden gym of the following specification: 1. Internal floor, equal to, or below 15m2 2. On my boundary (within 1m) 3. 2.8m tall 4. Normal timber construction/cladding I know I have to apply for planning consent due to the...

    Garden Gym height options

    @nickjb that's very interesting. The main reason I was leaning towards the moat was the fact I have to build this out of timber and wood cladding to match the existing items. I have no desire, or space to go over the 15m2 size for the internal floor, so if this makes the combustible element moot...

    Garden Gym height options

    @cdbe I've seen in other threads where this is suggested. I'm not sure I can get my head around this sort of construction with a timber frame. I guess i'm drawn to the simplicity of the moat as it's easy to monitor...

    Garden Gym height options

    interesting. Did you have to then construct it out of non-combustible material? If so, what did you use? I was going to build this out of timber as per my other buildings so it's in-keeping. The cladding also weathers down so isn't oppressive for neighbours. I'm currently getting a front...

    Garden Gym height options

    Hi @Larry1990 that's some sound advice thanks, but unfortunately due to space my only option is to build on the boundary. I don't think I will get planning permission for 3m in height being this close? If I was it would defo be an option. I don't want possible issues with damp ingress. I guess I...

    Waterproofing a building below ground level?

    back to the drawing board on my build then. As it was going to be a timber construction on a concrete slab it seem more problematic?
