How did you decide on the boiler you have now? Was it because of cost, ease of operation, efficiency, location of service provider, friend has one and it works good for him, etc.. Obviously output was determined for size of home/shop but most makers offer multiple sizes to cover Btu output. Are you just looking for the latest and greatest? It seems alot of times we have the Ford vs chevy going on, they both get you from here to there so why the dispute and name calling? If is just preference let's just call it that. I am becoming one that hates all of the choices at the grocery store I mean really, how many different kinds or yogurt or toothpaste do we really need?! :gulp: It is nice to have the choices, but how do you weed through all the marketing and hype to find one that is truly cost effective and performs as advertised and as needed? :grrr:
