You know that thing where you can't work out why the boiler is losing pressure then you notice there is water dripping through the kitchen ceiling. #IDontLikeMondays

@Workshopshed A side-tracked / almost off-topic bit about having Gas Boilers that I remember I wanted to write anyway- so hope it's interesting!

Gas Boilers are not cost effective unless you're extremely lucky (my boiler engineer friend backs me up somewhat when pushed for answers about cost of all problems) which made me just get just get a big catering urn instead of yet another boiler or part that went wrong with it (basically it's like buying a new boiler every x years... so a big kettle / electric element for the cost of a upper-class kettle is 1 solution!) and just preparing bath 40mins before...if I wanted hot water... and basically accepting using less hot / warm water overall (so 2 aims here)...

Can say more but basically a big catering urn and less hot water beats all the hassle can't be done by any old person using a boiler so too specialist too from pipes, gas supplier, unit (almost 1000 sometimes), gas specialist / engineer per hour 100... = a total that is more than boiler itself and terrible ultimatum just for hot water)

So all it takes is just one problem to start going the wrong way fast economically and lazy engineers will just say "it's old or beyond economical repair" which is known as BER (for mobile phones too). The advert for 80-99% efficiency means diddly when any part goes wrong and you're locked out of everything and burdened with cost (even to shut it off!)

Think about that next time boiler goes wrong and do the DIY way / minimise - with catering urn / boiler!
