The new water heater energy efficiency standards will be in effect, starting in April 2015. U.S. Department of Energy (DOE) Secretary Steven Chu announced in April of 2010 that the Department had finalized higher energy efficiency standards for a key group of heating appliances that will together save consumers up to $10 billion and prevent the release of up to 164 million metric tons of carbon dioxide over 30 years. These new standards — for residential water heaters, pool heaters, and direct heating equipment such as gas fireplaces — will reduce air pollution, prevent the release of harmful nitrogen oxides and mercury, and avoid emissions equivalent to taking 46 million cars off the road for one year.
Residential water heating products affected by the new 2015 Energy Conservation Standards include gas-fired, oil-fired, electric, instantaneous gas-fired, and instantaneous Electric Water Heaters.
To meet the new DOE regulations on energy efficiency, tankless water heaters go beyond the requirements and provide an average of 22 percent more energy-efficient than the tank-type heater.
Keep in mind that without a proper water softening system, tankless water heaters are required to be serviced once a year to clear calcium buildup.
Tankless water heaters are more popular than ever. They offer long-term savings, are more eco-friendly, and best of all – they offer an endless supply of hot water on-demand. However, it can be overwhelming to understand how tankless water heaters work, what it takes to install them in your house and select the water heater you want to buy.
