I have been looking at the GB142-24 as back upfor a geo system and for some additional space. The other day someone pointed out the Lochinvar Knight 80 as a well made unit modulating in the same range for about 25% less $$. unit will not be used for DHW just a few IFR zones and to boost the geo on sub 20* days. It will also provide total backup if the geo goes down at all. Should I spend the extra $$?

Thanks
