I am looking at the 'pros and cons' of getting a new boiler to support an 'S' plan configuration, Oso unvented cylinder and 21 radiators. My present boiler is an Ideal Classic FF280. I have narrowed my manufacturer options down to WB, Valiant, Viessman and Atag. Rather than get into the usual arguments about which boilers have better heat exchangers, better support etc, my question is this: 'which of these boilers play best with Evohome' controlling two zone valves?
As an aside, I see that most of the latest generation of boilers have low power built in pumps. Am I correct in assuming that they also have a built in ABV suitable for a fully TRVd house? Any other considerations that I should bear in mind? Thanks.
