Hello: I looked at the links you sent and the less expensive one doesn’t look like a power vent heater. If you can move the heater to a place not inside the conditioned space AND not subject to freezing, you could possibly use a conventional, non-power-vent heater, which would cost a lot less and would work in the event of a power outage. I’ve seen a lot of complaints with power vent heaters, so would try to use something simpler if at all possible.
Thanks Larry, I’m all for simpler, just not sure what you mean about moving the water heater to a “conditioned” place. It would be in my basement.
Still, I find this power vent heater from HD for $836 for the heater itself: http://www.homedepot.com/p/Rheem-Performance-40-gal-Tall-6-Year-40-000-BTU-Power-Vent-Natural-Gas-Water-Heater-XG40T06PV40U0/204318424 It has a six year parts warranty and one year labor warranty.
Thanks, looks like Home Depot prices it based on location. That model where I’m at runs $778 with a $100 rebate from my gas company. Still, if there’s a way for me to go with a non-power vent heater then I’ll do it… just need to figure out what that means. 😉
