Quality Gas Fired CH System Boiler

[Jackrae]

I am in the throws of getting my old gas fired CH boiler changed out but my plumber is dragging his heels.

I had originally specified a Viessmann 200-W system unit rated at 35KW, mainly because of the stainless steel heat exchanger and the large passageway within the exchanger. The plumber I'd chosen was on the Viessmann register so I'd also get the extended guarantee.

However as he's dragged his heels for quite some time I'm getting to the stage of looking for someone else; maybe even looking for an alternative boiler type.

So, what is the best quality gas CH system boiler I can get rated at around 35KW with an SS heat exchanger which has good open passages unlikely to block over time. Combi features NOT required.

Many thanks

35Kw is a lot. What sort of property are you heating?

You would also get a much better response in the plumbing dept.

Went to the trade site as I figured I might get objective response based on installation experience rather than subjective opinions.

House is a large old stone house of classic edwardian construction - solid stone walls with wooden straps, laths then plaster. No real options on wall insulation unless one completely rebuilds internal walls.

Current boiler is rated at 24kW which is hard pushed in cold weather and modern 35KW unit offers modulation down to less than 12KW
