direct vent or power vent gas water heater
I would appreciate any comments on my choice between a direct vent vs. power vent water heater as we convert to gas heat in our 1960s ranch house. I am concerned about fumes drifting into our kitchen windows, which are ~5' above where the vent would be. I like to keep windows open whenever possible.
Other pros and cons I see with my choice:
direct vent--pros--does not take air conditioned/heated air from the inside only to blow it outside, works in power outage, no fan to break years from now, quiet
power vent--pros--might be more effective in keeping fumes out of kitchen windows (although one HVAC company told me fumes could a possible concern with either type. . .they are not pushing one model over the other)
The price is the same for one HVAC company, the direct vent is $350 more expensive from another. They both said that vents needed to be 4' away from a window.
