Any plumbers on here!? Advice: Unvented Hot Water System??

[535dman]

Not sure if this is the right place to post this but here goes anyway!

Just moved in to a new home and am finding the water system very irritating. The house currently has a gravity system with tanks etc in the loft but the irritating bit is that everything in the house is connected to a very noisy pump (a power shower type of pump located in the airing cupboard). Even if you flush the loo the pump goes on turn any tap on and the pump goes on!

I've called a plumber in and he's advised that to remove the pump from the system (and only connect it to the power shower where it should be connected!)he'd need to re do all the pipework through walls, roofs etc and would cost a small fortune. What he's recommended is to switch off the gravity system alltogeter and install a Megaflow hot water system which he said would cost in the region of £2.5k all in. The house is a 5 bed detached. I wanted to know if the quote is realistic and if the megaflow systems are any good. Someone just told me they are prone to explode if not looked after and can take out an entire side of a house

Thanks - The normal pressure without pump isnt too bad at all but re-doing it without the pump is the issue as all pipes/plumbing go through the walls and under the flooring etc. The Pump and tank are both located within a bedroom cupboard!

Don't have a clue about the pipes mate..thats what the plumber said and thats why i'm on here to find out if he's trying a bit too hard to make me get the megaflow

He's told me it's not possible to remove the pump and re pipe (without going through the floor etc) the way its currently set up. I've got another chap coming to have a look tonight will let you know what he says

Right - the "other" plumbers been and said the same - can't simply take the pump off - would be cheaper to leave it on and get another unvented system

Pipes are the problem - to be honest I'd rather have it removed as it's in a cupboard in a bedroom it sort of wastes the room as it's too noisy at night
