Best boiler - Condensing (not combi) - unvented......some questions...?

HiI have posted a few question here about different things and I havesome more..(thanks again in advance)...Ok, looks like I am going to change the boiler in the house for acondensing type - not a combi - probably an 'unvented' system. Thishas come from several recommendations as 'the best solution' - andI'll be totally honest, I don't really understand how it all works!I currently have a boiler that has two seperate rad circuits (twooutputs from the boiler) - each goes into a valve that is attached toa room stat - I have one upstairs and one downstairs. All my rads have 'yorkshire' style connections. I want to change allthe upstairs rads to have TRVs on them - so that when I convert theloft (a few years away yet - and I'll want to fit a mains poweredshower in the loft), I can fit the same up there and be sure of a warmroom.Downstairs I will want to add four rads to - which will heat a room inthe barn attached to the house. I am considering ditching theyorkshire valves and fitting TRVs on all - so that the same circuitcan be used for the barn - which will also have TRVs - that way theroom stat is bypassed - else it would keep switiching the circuit offwhile for example, the barn is still not up to temperature.Anyway, I think this will work but can I ask a couple of questions....1 I'm sure someone suggested it before - to remove the yorkshirevalves - is it simply a case of taking the valve off, revoming thelong tube that runs part way along the bottom of the rad, extnedingone of the water pipes to it attaches at the other end, and fitting aTRV - or do I need new rads?2 Just what is the best boiler? I'm not too fussed about £500here or there - but I am not planning to move and my gas bills (mainlyheating) run to approx £70 per month (averaged out over 12 months). Iwant an economical solution.....I just can't seem to find any plumbers/gas fitters that areexperienced enough to recommend a solution - you lot have been morehelp! I want to be able to decide for...

I believe large parts of the ex-soviet union have thermal meters in flats in those huge blocks - a quarter-turn on-off tap on the gas supply to each flat, even cheaper than the vodka and bread :-)
