"We Guarantee Your Comfort"
1 25% of every American household energy dollar is spent producing domestic hot water. 
Nationwide more residential energy is consumed by domestic hot water than on anything but heating and air conditioning.
2 Electricity is the WORST way to heat hot water while natural gas and propane gas are much more efficient, smarter choices.

Based on national fuel price averages of $1.46/ccf and $0.09/kwh, the cost/100,000 BTU's is $1.46 for natural gas and $2.64 for electricity. Just under 60% of North American households have access to natural gas, and if you don't, propane gas is available to almost everyone and is still a better value than electricity. In addition electric water heaters have only a small fraction of the capacity of gas water heaters. So if you like expensive, short showers, with cold water at the end, use electric; otherwise gas would be a better choice.

Modern gas fired tankless water heaters are the best alternative available to todays homeowners to reduce their residential energy consumption.
A typical gas fired tankless water heater costs about 2-1/2 times as much as a standard tank water heater. However it will pay for itself in just a few years or less, and will last twice as long a tank. To determine what tankless will do in your home click here.
