Condesning (NOT combi) Boiler recomendations

[gremlin_95]

The only off-putting thing about Viessmann is the price of the parts.

Yes, definitely. The Vaillant 612 goes down to 3kw which is even better.

[Mathew Newton]

Yes, whilst one would hope not to require much in the way of replacement pa rts it has to be a consideration. Similarly, there is some comfort with a W orcester given that their massive numbers has resulted in being spoilt for choice for installers and parts suppliers.

In my case I am restricted by my preference for a simple heat-only boiler i .e. 2-pipe connectivity and with the pump/diverter gubbins all external to the boiler.

Which would depend how often they're needed.

[gremlin_95]

Yes, you'd hope that they won't often be needed.
