    Designing en suites with only cold water at the basin?

    Hi Klaus, good idea to consider that, unfortunately it seems to have broken ChatGPT https://chatgpt.com/share/67bc2a54-fd80-8005-9ec9-b62afcdc3b13 so I still don't know. But I think I want to avoid having hot from the boiler other than where it is likely to be used for more than a few seconds...

    why would repair costs be lower on a newer boiler? edit - you mean no need for repairs at all as its new? rather than the same repair would be less on a newer boiler. One of the things I'm seeing said is the newer boilers are more complicated so more to go wrong and more expensive parts and...

    I'm guessing you are a heating engineer? do you see people preferring to just get a new one at the first sign of trouble for the new warranty? £3000 / 120 months = £25 a month. I can see that appearing normal to many people. Just checked and sure enough you can in effect lease a boiler on...

    right now i get it, 10 year warranty, peace of mind, when that is up, peace of mind has gone, first time something goes wrong its the easiest sell to say get a new boiler as it will have a new 10 year warranty. And if thats the normal way of things then thats just what engineers expect people...

    Ah yes like cars, most just want to lease it so they never have to be concerned about repairs. If they have the money thats fine but all these leases and contracts and subscriptions add up and I don't know where people get the money. If they take a hit in wages, as its going out the bank...

    I realise its not the whole story for boiler efficiency overall but what does it mean if not related to that? One thing i do understand about efficiency is that replacing a boiler more often due to condensing having shorter life, more expensive parts, more complicated to fix etc should be taken...

    Can I replicate a powerflush by running the boiler whilst filling it and opening the drain valve?

    I'm seeing more recent boiler pumps might not have a capacitor but in case yours does... I changed the capacitor in my pump, £5 and 2 minute fix. The capacitance was something crazy low like 0.01uF when it should have been 2uF and it was still running, so it appeared the problems I was getting...

    Taking out the existing hot water system? Yes seems like it makes most sense rather than trying to modify anything. I'd missed under sink instantaneous heaters from the thinking, easy to satisfy the requirement without running costs as you say can just have it off or on low for anyone thats...

    Whats the reason you feel like you keep needing to do the flushes?

    10 rads on one 15mm feed!

    Recently got started on the plumbing side of our project Victorian house and realised something daft about the heating system. It is working so wasn't a priority but wasn't doing a great job overall which I guessed could have been the elderly boiler, sludge or not great old radiators. It has...

    Designing en suites with only cold water at the basin?

    I would agree until the building regs issue was pointed out. And the legionnaires issue about the current system. You know what people can be like, if they see i've ignored one reg they might wonder about the quality of everything else. As it just needs a tee and a hose from the cold supply its...

    Designing en suites with only cold water at the basin?

    no it already happens to be about equidistant to both but they aren't adjoining rooms. Anything that stores hot is going to take space for insulation and lose heat anyway. I think the compromise is going to be non-storage instantaneous heaters and having mixer taps which have a separate handle...

    Its going to have to be the undersink ones then, happy wife and happy HSE

    Designing en suites with only cold water at the basin?

    There is no way the current hot water storage is minimum 60 degrees when the heating is on a low setting. https://www.hse.gov.uk/legionnaires/hot-and-cold.htm We're probably lucky to be alive breaking all these HSE regs

    Designing en suites with only cold water at the basin?

    I've noticed with flushes its quality not quantity, there must be more gone into the design than is obvious. I regularly empty a dehumidifier into the loo and if i've just used it tried to use that water to save a flush, just doesnt work even though must be a similar amount of water

    Designing en suites with only cold water at the basin?

    oh ffs. you're right but good catch as I'm getting stuck in tomorrow. chatgpt again, great for these type of things: My first thought was its an en suite so surely thats just a bonus either way but no we have legislated ourselves into an unsustainable standard of living we can no longer afford...

    Designing en suites with only cold water at the basin?

    Thanks well thats an option i didnt know existed, I was just thinking about the ugly over sink ones, could be the answer, TBH my wifes eyes lit up at the idea and you know what they say about happy wife... I've just asked Chatgpt to do some calculations of cost and time and waste to get 2...

    Designing en suites with only cold water at the basin?

    Being not a wimp I never wait for hot water at the basin and the family have got used to it over the last few years in this new to us Victorian house but would most people see it as essential to the point I should consider the next buyer and make the effort to have it? Don't get me wrong its a...
