Tankless Gas Water Heaters and Tank Gas Water Heaters
Noritz America called me last week; they are manufactures of tankless gas water heaters. They had executives arriving from Japan with an interest in visiting a Southern California construction site, primarily to look at the application of a Corrugated Stainless Steel Tubing (CSST) gas system. Because I train and certify CSST installers on location I got the phone call. I also represent State Water Heater including the Aurora model made by Noritz. The tankless gas water heater is finally catching on in America. The tank type gas water heater has been an affordable installation for generations, but the energy to maintain a vessel full of water is sometimes not the best household application.
Some issues to investigate when considering a tankless gas water heater...
Higher gas volume and pressure
Effects on the manufactures warranty if a recirculation line is installed
Flue/vent materials should be to the manufactures specifications
Sufficient (combustion) fresh air supply
A few features & benefits of tankless water heaters:
Continuous hot water on demand (tankless water heaters provide a steady flow of hot water whenever and wherever you need).
Compact, space saving design (indoor and outdoor tankless water heaters are just over 2 feet tall, weigh 55 pounds or less, and attach to an interior or exterior wall).
Energy efficient tankless gas water heaters are as the name implies very energy efficient $300 federal energy tax credit on some tankless gas water heaters qualify for tax credit incentives available for a limited time.
Features & Benefits tank type gas water heater:
Is best told in a short story.
Last week my good friend and Pastor was complaining about the cost of replacing his 8 year old 50 gallon gas water heater. Complete job $850.00. So we did some math...
8 years x 365 days = 2920 days $850 divided by 2920 days = $0.30 per day for dutiful appliance service whether you use it or not. Of course add the cost of natural gas necessary to maintain 50 gallons of water at a ready to use temperature of 115 degrees.
Now do some math with the $4000 wide screen TV or $45,000 SUV at less than 5 years service. The tank type gas water heater has always been an affordable appliance when installed correctly with the right application.
