My gas bill, with a gas hot water heater and a gas dryer varies from $32 to $39 a month. There is no way i can justify going electric for hot water. My electric bill runs $150 to $300 a month. Not including hot water, heat, dryer. NO WAY do I want to add to that!
Well, especially when you pay double-and-a-half to triple for the same amount of heat when using electric.
Although, believe it or not, instantaneous gas water heaters do exist. I saw them install one on this old house. Now since it’s instantaneous, the gas service requirement is enourmous compared to a storage type unit, just like it would be with electric, so the line to the water heater and/or the service/meter size for your entire house might not be big enough.
