I have not called any professional because there is the Coronavirus "how long is a piece of string" Pandemic. Since January 2021 boiler started leaking water drops after I saw heavy smoke coming from the flue, so I turned boiler off and took the bottom cover off to collect the drops. I have put washing up bowl under the boiler to collect the water drops and then each day once or twice I empty it. The boiler is a few years old and so part/s sourcing is a challenge and it probably requires a total boiler replacement. From January 2021 to now I can see corrosion / limescale deposits and some rusty stains on the washing up bowl. I have switched from gas central heating to electric radiators. To bathe I heat water pot and use bucket. So I'd be grateful if professionals could tell me the steps on how to stop the boiler water drops until the coronavirus situation improves. The system has hot water storage cylinder, cold water tank and is therefore called standard / regular / traditional / conventional boiler. (i) Do I have to go into loft and do something at the cold water tank (large)? (ii) Do I have to drain cold water tank (large), if so is this by siphon pump as using plumbing wrenches might be complicated because it could cause accident for layperson? (iii) Do I have to shut the stopcock function in the cold water tank (large) - is there anything in the market to do it cleanly and for long time rather than using timber and string? (iv) Do I have to insert a stopper / bung in the water outlet - how can I make sure that water flow does not shove-out the stopper / bung after a few days or weeks? (v) Do I have an easier method - is there some pipe above the boiler that has a valve which can be switch off the water flow using a screw driver? (vi) Do I have to do other stuff for doubly ensuring water drops whichmethod is used remains shut? (vii) Do all registered plumbers / gas engineers have to carry gas masks by their regulation bodies, if eventually a professional has to be called? Thank you.

I was just lloking into the different systems available for heating/Hot water. Some Great systems are used by the members on here and I am tempted to use a Genvex Combi like @PeterStarck as it seems amazing logical to combine it all with the MVHR. However, i just found this : https://www.youtube.com/watch?v=qyQRTg7Gpw8 It seems an incredible good system, even though not including the MVHR , but still a very good, space saving method which seems easy to use/install. Website is in Norge https://www.polarenergi.com so anybody wanting a look might need to look at their NZ distributor as I couldn t find UK or even US website http://polarenergi.co.nz Anybody on here ever looked into this? Is it a good system, or not really worth the trouble ordering from Norway as similar exists in the uk(which ones>? )

Hi, almost certainly a question for our resident eggspurt @Nickfromwales The picture below shows the connector to join the 32mm ground pipe to the 22mm internal pipwork. The brass is (I think) just one of those bog standard 1" tank connectors. But the male union thread on the other fitting is plastic. Whats the best method to join these? I'm concerned that too much PTFE tape/chord could cause the plastic thread to strip or crack. This joint is going to be buried in the wall so I need to be sure of a permanent connection. Ta muchly in advance.

Hi all, Just looking for some views on what system we should put into our self build. Some details. Timber frame - walls at 0.14, floor 0.1, ceiling 0.1. Ufh downstairs with rads upstairs. Mains gas available. 4 bed, 3 bathrooms. May fit solar pv if we can get panels at the right price. Was thinking of gas boiler feeding into thermal store. Immersion top & bottom ready for pv or as a backup. Any thoughts? CC
