Decisions, Knight, TT or EVO a tough choice
I am getting ready to replace a boiler room in a 1940's 10 unit brick apartment building. With new windows and some insulation inprovements the heat loss should be around 160K + domestic hot water
I plan on 2 boilers, the number 2 will be a WM CGI-6 167 input
My top 3 choices for the lead position in no piticular order will be a Knight KBN150, a Hamilton EVO 180 or a TT175. The domestic hot water will be a 120G-TT indirect connected to the lead boiler
In my area the Lochinvar are the most popular and cheaper.
It appears the EVO and TT have better warrenties.I like the design of the fire tube HX on the TT
The EVO has a built in flow switch and secondary high limit and a set of contacts for a secondary heat call (the WM when needed) it also has some nice service frendly features
I would not even consider a alumunin boiler
Any thoughts appreciated
