Someone mentioned that conventional gravity fed back boilers are being phased out. Is there any truth in this and, if so, since I can't see me ever wanting a combi, what are my options when it comes to change?
Thanks, Tony
Conventional (ie. non-condensing) boilers are likely to be phased out. Simply done by Government increasing the minimum boiler efficiency to above that possible without condensing.
I don't know of any condensing boilers that support gravity feeds (but I also know of few boilers!) - so you may be required to change to a pumped system if you replace your current boiler. As for back boilers... ?
You won't be required to go to a combi system - non-combi boilers will still be around - its just non-condensing boilers that may dissapear.

This isn't the caravanning ng ... gerroff :-))))))))

The term conventional can be applied to mean as opposed to combination boiler or it can mean as opposed to condensing.
It's the non-condensing models that are to be phased out in the next few years.
Boilers come in three sorts combination, system and plain. Combination boilers produce 'instant' (um...) hot water. Plain boilers simply heat the water pushed through them. System boilers include the pump and other components that implement a sealed primary circuit (see FAQ below).
There is no good reason to continue installing heating systems that use convection of the primary water to heat the HW cylinder. There is much to be gained from using a fully pumped system:
1) Control of the HW temperature. 2) Much better heat trasnfer to the HW cylinder. 3) ... which leads to faster recover times for the HW.
LOL - you spotted my deliberate mistake then?

As combi boilers now take 70% of sales of 1.1 to 1.,2 millions boilers a year, a conventional boiler is now a combi.
Not quite right. It is boilers less than 86% SEDBUK efficiency. Condensing has little to do with it.
Well move to civilisation.

Yes we should all live in towns and cities, it makes much more sense from an infrastructure point of view.

All perfectly true. But with a FP system you are vulnerable to power cuts. I admit that we dont get them very often in our area, only one this winter...

But according to you everywhere is habitable, so how much of UK land is "lacking" and should not be lived on, can it be defined as anywhere without mains gas?

But when Steve said he did not have gas you said "well move to civilisation" what exactly are you saying, I think we should be told.
He lives in Wiltshire. Every been there?
Since there are no non-condensing boilers with a SEDBUK >= 86%, I assert condensing has much to do with it.
It sounds to me that that's where he already lives.
