Ok I would be curious IF anyone knows for sure an answer to this ?
Opinions are welcome too !
I have an 80 gallon elect water heater in my 2 person home. It is on a day/night meter. Heats between 11 pm and 7 am on a third leg of the meter so no timer is required.
My bill runs around 70.00 in summer and about 80.00 in winter. Its a cheaper rate at night but I believe I pay a little more for the meter ??
I now have Natural Gas to my new furnace. I have no real good spot for a chimney for the WH but could go with a direct vent adn run the PVC out the back of the house.
Now what is the CHEAPEST option.
1) leave current system alone
2) go with a 40 gallon and chg meter to a regular day meter
3) go with a NG forced vent pvc heater
Now I assume the NG option would cost much more for the tank. The 40 gallon tank would be the cheapest I would think but would my bill be higher going back to a regular day meter ?
I keep the 80 gallon set at 120 degs and we seem to be fine on hot water for the day.
I have asked the gas and elect company and they seem to think my current set up is the cheapest.
Ok lets open the phone lines !
