Long Short... PE-people, do you think the new t5 insert can do the job in a 1800 sq ft home, cathedral ceiling in the room (22') it would be in, some drafty spots in house, no long hallways, fairly open house. The wait-time for (our on order of PE Summit Insert) is bamboozling me... giving the boss time to look at pictures of the pretty new cast iron model... I like em both, just want it to do the job. I know the Summit will do it, question is, would the t5 work. I think I know what folks will say (bigger better), and I agree....but if anyone's experience out there suggests the t5 is plenty, that might convince me... I tend to be an over-kill type with everything. Can't wait to get our install...
