Have narrowed my choice of combi wall hung boiler down to
the Vaillant EcoTec plus 837 or the WB Greenstar 35CDI.

Any helpful comments to assist with making the final decision ?

Thanks

House spec is:
large 3 beds, 3 floor midterrace, solid rubble walled (ie poor
insulation) house. with 1 bathroom and 1 ensuite shower but little
simultaneous use.
Present boiler Ideal Mexico RS65 okay for CH & HW.

Frankly this is a bit over the top and you could probably save a few quid
by down grading to the the 28-30kW versions.

Also the gas pipe for the 35kW boilers will most likely have to
be 28mm, but you'll probably have to upgrade anyway.

Both makes are in the upper-mid market. The Vaillant has a s/s heat
exchanger.
