Small boiler recommendations

[BigBurner]

Thanks for all your comments so far. I will look into these, but any more still welcome. BigBurner - you mentioned Ideal do a small combi, do you know if it's any more reliable that our present Ideal Response? We've had nine good years out of ours, only recently experiencing problems, but I know they get slated.

The ideal is the Isar. But, only buy one of these if it is the only one that will fit. Your Response should have lasted 20 years.

Broag do make good boilers. If one fits, go for it. And get the outside senor and OpenTherm Controller too. You will benefit from that.
