A7 5-year Ownership and Operating Costs
Operating Cost of Various Water
Heating Systems:
The table below compares the initial and operating costs of
various water heating systems. As shown, the AirTap™ yields the lowest total cost.

After the first year, the AirTap™ will continue saving
you $200 or $300 every year for gas or electric water heaters,
respectively. Average savings are for a typical 4-person family.
Depending on the cost of energy in your area and the amount
of hot water you use, these savings can reach up to $500 or
more every year.
If every household attached AirTap™ to their current water heaters, over 75 million tons of pollutants could be removed from the environment per year, and could save over $5 billion per year.
In addition to these benefits, AirTap™ also releases cool air which can be ducted into your household as a means of air conditioning, and acts as a dehumidifier, removing any condensation that may form around the AirTap™ unit.
