Most reliable combi boiler 2011

[Triffid]

I'm sorry but that is utter nonsense in relation to modern combis.

[John]

I am going to have a look at the diverter valve

[The Natural Philosopher]

Not in the context I said it. Either the combi is massively overspecced for CH use, or its massively underpsecced for HW. If its IS over specced, then its no longer small or cheap.

[PeterC]

Yes! I sthe vatican aware of this - it's obviously aware of "...suffer little children..."?

[tony sayer]

I'm quite surprised that a fuel like Gas is being used up much faster than what it ought be whereas coal is plentyfuel..

[tony sayer]

So no teenage daughters then;?...

Methinks you'd change your mind if you did!...

It is something to do with the previous previous government being a bunch of dogmatic bastards and for reasons I do not fully understand, they did something that made burning gas look attractive to the buyers of the nationalised CEGB.

Possibly connected to mad bitch Maggie's hatred of the coal industry, whereas at the time, we had plenty of gas.

[tony sayer]

In article , Tim Watts scribeth thus

Then was then and yesterdays politicos we need ones for the current situation!..

And who know what there're doing..

Perhaps thats not gonnna happen then...

[The Natural Philosopher]

Why?

compare the gas drilling industry to the coal mining industry..and all is revealed.

[The Natural Philosopher]

Nope, more to do with the Bitch Maggie having public opinion on her side hating the coal miners UNION.

We have the same problem ow with the public sector,. but Cameron is forced to sit on the fence there, and as everyone knows, it takes a man with no balls to do that successfully.

[John Rumm]

Alas in this area TNP is no different from Dribble - both true believers, and neither is going to let inconvenient facts get in the way of their dogma.

[Dave Plowman (News)]

I'd like to hear of a combi which can fill a bath as quickly as two 3/4" taps, one of which is supplying water at 60C, and the other cold. And feed another hot tap or two in the house at the same time.

The thing with a storage system is you can design it to do near enough what you want - assuming you can site the header tank reasonably. Any instant system has practical limits.

[The Natural Philosopher]

What header tank? mines 32 miles away and a 100ft higher..

Any

Yes.

[Andy Dingley]

I don't need to fill a bath that quickly, so the question is moot. I just need to fill a bath quickly enough that it's ready for me by the time I've got undressed. Anything else is just superfluous.

[The Natural Philosopher]

well that takes about 5 seconds.

Anything else is just superfluous.

Agreed: sub one second bath times are superfluous.

[John Rumm]

No one is arguing that it can. Only that being able to do that is not the minimum required level of performance in all situations. If it is, don't fit a combi.

To argue that all you can get from any combi is a dribble of luke warm water is simply ignorant.

Precisely. These are all things one needs to consider. In my case, a conventional gravity fed storage system won't hack it - no space for the header tank and not enough head. Combi (alone) won't hack it either - not enough peak delivery. Hence mains pressure storage system, or large heatbank with substantial HE and possibly a combi as well is what fits the bill.

[Dave Plowman (News)]

I could see it being useful. If say the storage was a long way from the kitchen and the boiler close. Use the combi side just for kitchen hot water.

[D.M.Chapman]

Alpha flowsmart is a combination of both

or 50l Store is used in the feed to the boiler via a blending valve - idea is that the combi is fed warm water so doesn't have to work as hard. When incoming feed is icy cold in the winter it makes a difference.

[John Rumm]

Yup, there are a number of these "system in a box" type arrangements out there. The alpha one uses the store and combi functions in series rather than in parallel as might a system designed with separate components.
