Hello. Am just about to make a decision on new boiler/cylinder combination.
I own a 4 bedroom, 1 bathroom, 1 WC and 1 shower room terraced house.
I've v roughly calculated I’ll need about 120,000 btu in total.
I’ve had 2 separate (credible) options recommended to me:
Option 1: Moving the boiler & cylinder into the cellar. Doing this by installing a condensing boiler, together with a Megaflow cylinder (both in the cellar). A Keston boiler was recommended as there is no outside wall directly next to where it will be sited and the Keston apparently gives move flexibility regarding the route the outside pipes (?) etc will take. The down side is that this option is costly as the boiler itself costs approx. £2k, then there’s the cost of the megaflow, plus all the labour.
Option 2: Using what my plumber calls ‘one of the new generation’ of combination condensing boilers (he thought a Valliant). So obviously no cylinder and he tells me the cost of the boiler is a lot less. I’m not sure if this will give the same flexibility regarding where it can be sited (eg not sure if it can be down in the cellar). This will probably need an outside wall, presumably?
Does anyone have any views?
In particular:
1. I’ve only ever had combination boilers in flats. Are they able to deal with bigger houses? Does this sound like a sensible solution?
2. I thought combination boilers suffered from the old problem of losing hot water from one area when another is using it (typically the shower – when I’m in it!)
3. Apparently, there are cost implications to the megaflow – especially yearly servicing costs. Any idea how much this will be? We do have sufficient water pressure, so this wont be a problem.
4. What about this new generation of combination boilers?
5. Any other advice?
Cheers, I’d really appreciate any views.
