In Reply to: add gas heater ahead of electric posted by dave delguzzo on April 02, 19100 at 22:35:36:
: I purchased a 75gallon Jacuzzi tub and have a 50gal electric tank. I would like to add a gas hot water tank before the elec. tank. All cold water would be heated by the gas and the electric would maintain the hot water. That way I can have 90 gal. of hot water available if my wife takes a Jacuzzi bath and I take a shower. I have a 90% efficiency gas furnace and no chimney so how can I vent the gas hot water heater. Do I need to purchase a power vent blower or can I vent it through a wall? Is there a cheaper/better way to get more hot water. The house is brand new and the 50gal is not enough.

Cost wise I would put a designated 50 gal electric water heater just for the jacuzzi.You do have natural gas and it sounds like you would need a power vent. Pretty expensive. Gas has a quicker recovery. Does your jacizzi have a heater? If you have one heater to the jacuzzi you can set the temp for your comfort.The choice is yours to make.Gas will cost you more to install.
