- Total dependence on mains water supply (but not mains pressure, if you put in a booster set). - cost, if you have already got some of the components of an alternative setup. (Though based on what you've said, you have no unvented cylinder, so you can roll the saving from not buying one...

My three-pennyworth on this is that IF there's enough room (and the original post suggests there should easily be!), you could get rid of all the tankage in the house except (maybe) for a break-tank for a booster set and a buffer tank for hot water. (You could go for a package such as Grundfos...

Total heat available is too much for the building as a whole. The lower-floors boiler is definitely too big. But overall, taking account of the benefit of not having to run long primaries top to bottom of the building, not too bad a design. The main upside is that if one boiler goes down...

Generally speaking, power flushing is too labour-intensive to make sense unless it's part of a bigger job ( such as a boiler-change). The cheapest solution if you want only a flush of all your radiators and boiler is a specialist company. Sent me a PM with your contact details and I'll have...

[Yawn] Why is it that no-one reads the instructions and data-sheets carefully prepared by makers of compression joints such as Conex and Kuterlite? I think it's correct that ALL specify that joints under 42mm should be assembled without any additional sealants. Mineral oil lubricant only...

Most of the comments are exactly correct. Boss = missus!! If I'd had the relevant tester(s) to hand, I would have done the tests suggested at the start. But since it's my own system, I'm a heating engineer, and there were no grounds to suspect any fault and I wasn't about to quote a fixed...

Yup - that's the sort of possibility that worries me! Actually the house is 3 floors total but half the first and all the second is on a secondary CU - I think there was a separate flat on the upper floors at one time. Then, when it was rewired later, they followed the same arrangement. So...

The whole of the affected circuit is on the First floor. The stairs/landing lighting is on the downstairs circuit and is OK on a different RCBO. Other test results to this point are irrelevant: there's definitely (very) low resistance Neutral to Earth on the (single) cable leading to the...

One of those Ignorance is Bliss / Wish I'd Never Started This stories. The boss wanted an Induction Hob and no spare slots on 8-way Consumer Unit. Also EXTREMELY old (although probably as safe as it ever was - I thought), so change it for a CU with more slots. And, given that MCBs are now...

Do you still have the MADQ you mentioned? Do you want to flog it to a Good Home? (ie. for not much money!)

FFS! WTF does the RPM of the wheels of an airplane have to do with its airspeed (which determines whether it takes off or not)? The limits on acceleration with the engine at full throttle are (I guess) 95% to do with aerodynamic drag and hardly anything to do with rolling resistance of the...

Looks like the refugees from (eg.) BG who left because they didn't like the Tracker and automated time- and appointment-checking have found a safe alternative billet at Onstream! Anyone here know anything about the quality of the management there? I just heard of a case where a meter-change...

The house was presumably dsigned for warm-air. Putting in an alternative WILL be costly, disruptive and difficult. Staying with (updated?) warm-air could have enough downsides to outweigh the extra cost of changing to a 'wet' system. Accept that you need to spend SOME money, even on...

It's easy, with 20/20 hindsight, to see how this happened. IMHO, EVERYONE is at fault to some extent: - the fitter, for not marking the pipe before he pushed it into the push-fit, AND for not recognising the symptoms in front of his nose! With the connections arranged as shown and...

Another strong argument for 'Being Careful What You Wish For'. ANY 'filtering' service like this (and there are many, all competing in similar 'marketplaces') can only do so much 'checking'. If you believe otherwise, you're delusional. They couldn't afford to do it and if they did, too many...
