Lochinvar vs Navien High Efficiency Boilers
I'm trying to compare two boilers and having a hard time doing so. I know not to discuss price, but I don't think anyone will be surprised that the Lochinvar I'm looking at below is significantly more expensive than the Navien.
Design is for ~110k MBTU/h + DHW for 2 adults (standard use - laundry, standard shower, etc)
Below are the key stats that I (as a civilian shopper) care about (apart from price).
Manufacturer Navien / Lochinvar
Model NHB-150 / WHN156
AFUE 95% / 95%
MBTU/h 150 / 125
Turn-down ratio 15:1 / 10:1
Outdoor Reset Included / Included
Matching Indirect HW Tank None / Squire SIT050 52 Gal
Is there something critical I haven't noticed that is different between these models? All of the literature I've been able to find on the Navien claims that it is designed for easy install. Both of them will have an indirect water heater tank attached. I can tell that the Lochinvar seems to have a better reputation, but from the outputs alone I'm having trouble differentiating them.
