    Willis Heating System

    There isn't in anyone's. Warm water is very good at sitting on top of cold water and not being cooled by it/not warming it up Willis doesn't change that in the slightest; water can stratify and sit around not mixing or conducting at the hot/cold boundary very well Let's present a "all figures...

    Buying a 2nd hand car instead of an EV

    No, I don't agree with that contrived rhetoric at all, sorry. No one looks out the window and goes "oh, it's a nice day, I'll just go for a spontaneous 300 mile drive to use up all the range in my EV so I can exemplify the "wisdom" of some blinkered, stick in the mud forumite who waxes lyrical...

    DeWalt DWE7485 table saw quality issues

    For the last kitchen reno I decided to just replace the doors, got some really nice ones made to the millimetre by these guys: https://kitchenandbedroomdoors.co.uk/ They'll make drawer fronts to whatever size you want No affiliation, just pleased with the price, finish and service

    Not by the time your scaff boards have finished drying out and warped some, no. You'll only find out at some party where your sizeable cousin leans on the counter, on the same side as 50 poured glasses of wine, and 4 pans of chili, and then there will be a cleanup job and a half

    Advice needed - unblocking pipe work that traveled through walls/floors. Think the issue is limescale

    Be careful unblocking by pressurising the pipework if it's push fit. Vacuum cleaner on the wastes is a more sensible suggestion in that case

    Reduce UPVC frame width

    Single skin? Would be easy to chop half an inch off the brickwork on the rear half of the depth then mount the window from inside, butted up to the remaining brick. This way it'll look like you've chopped the frame All that said, it's a garage; no need to be precious about the window frame!

    Cavity Wall Insulation Question

    There may be no insulation in the cavity; it isn't the only place walls are insulated. Or there may be no insulation due to a build error. Inspections aren't carried out on every house; on large sites with many houses of the same model a representative sample of each will be tested for...

    Willis Heating System

    Let’s try something else. Imagine you have a tank full of water, and the whole lot is at 50 degrees. A pipe exits the top of the tank and goes to the shower head A water inlet connected to the mains pressure is at the bottom of the tank. Suppose the manufacturer had a choice of two different...

    Selecting a roofer

    It doesn't make sense. Single glazed windows present a colder surface to the room and are more effective dehumidifiers/suffer more condensation. Double glazed windows were likely better sealed against draughts. You have to consider changing habits; once upon a time draughty windows and doors...

    Willis Heating System

    So you understand A, but not B I'm not really sure what do with that They're both immersion heaters. You seem to accept that water heated by the element, near the element, floats away from being near the element. The thing that takes its place (for there must be something) is cooler water...

    Willis Heating System

    You can't understand something, yet assert I must be mistaken? Get over yourself All your sitting here saying "in my mind, in theory, it doesn't work" isn't going to change the universe's willingness to demonstrate that it does work, so perhaps you need to pour less scorn on those who...

    Willis Heating System

    So the the Willis heater must suck in at the bottom if the water is leaving at the top. If can't just be that the water that leaves does so because it expands Liquids aren't compressible, and neither are they expandable. A plunger in a tube with rigid sides (like a syringe) when moved, draws...

    Hole in soil pipe, would this cause a slow flush?

    That hole in the pipe will be useful. Buy a floplast strap boss from Screfix drill a 40mm hole in the pipe (encompassing the damage) like this (not central, offset to be "round the bend") and use it as a spy hole while a helper flushes the toilet I expect you'll not see a rush of water...

    Plastering around exposed rafter for bathroom

    In the ceiling you duct it to a vent slate In the wall you have a long core drilling session and duct it to outside Both take about an hour, but the wall is typically easier because you can stand on a floor and drill from the inside with the wall, but with the floor you're pulling slates out...

    Buying a 2nd hand car instead of an EV

    Well, your thought exercise didn't set out accurate starting conditions so really I was making a "both the unspecified ICE and the unspecified EV will probably make it to the next fuelling point" claim, rather than a "oh the ICE would definitely make it, but there is a genuine doubt the EV...

    Buying a 2nd hand car instead of an EV

    America? Land of gas guzzling engines? Reasonable to say they have infrastructure every 200 miles to help the 5.7litre Chevy drivers get across the desert? I think my Tesla could probably make it too.. Good thing about electricity, if they did want to put infrastructure on the long desert road...

    Buying a 2nd hand car instead of an EV

    If we're going to make ridiculous arguments, Tom Hanks in castaway would have been less screwed with an EV and a couple of solar panels than an ICE I'm working with a company at the moment that are developing a giant rollable site powerbank. It's like the electric version of a Jerry can
