Efficiency of water heaters
I am very concerned about climate change. Would like to upgrade house to use less carbon energy.
We have just had a new high efficiency furnace installed with 3 "zones" which I love.
Now the big decision about which water heater is becoming difficult. Also, person who installed furnace is concerned that we have water heater installed soon because he is afraid of carbon monoxide.
Our furnace and water heater are in basement. Then we have two levels above that. The plumber says the furnace guy is afraid to finish the venting side of it because he is afraid of heights. The furnace guy is encouraging us to get a power vent.....prob to avoid the vent issue and he plumber is now pushing an electric water heater.
I know power vents are expensive. My question is do they save much energy compared to a 48 gallon Bradford White 65,000 BTU Defender safety System extra recovery energy saver residential natural gas water heater?
I am assuming an electric heater would not be a good pick if wanting to save on carbon use.
Thank you very much!
