I have been lurking on this board for the last week and could use some advise. I am looking to replace a 25 year old Weil McClain GV4 series one 105000 BTU boiler that is connected to a Amtrol Indirect H/W heater. I live in upstate NY (Syracuse)which I believe is in heating zone 6. My house is a 2050 split level built in the mid 1970 that has been update with new Windows and Insulation recently. The system is split into 3 heating zones and the indirect HW heater. 85 feet of Slantfin aluminum baseboard split 44 on main level, 34 on second floor and 7 feet in a basement media room. We used 172 Therms according to our last utility bill which cover 2/10 thru 3/10.Last month was unseasonable cold never getting over 30
We have no heat or hot water supply issues with the current system. I have noticed since gaining some knowledge on this forum that the system short cycles a lot, cycling multiple times an hour.
My plan is to eliminate the small basement zone and tie it into the 1st floor zone. I have gotten 2 quotes so far from local HVAC firms with solid reputations The first company quoted Lochinvar Knight KBN106 using the exist indirect H/W tank. The second company proposed a Navien Combi unit NCB-210. I like the idea of the Combi but have read some negative thing mostly on the older C series.
My questions are 1. Are the units the proper size 2. Is the Navien a good reliable option hot water supply should not be an issue (3 people basic needs) 3. What other brands should I be looking at
Thanks in advance you guys are a wealth of knowledge.
