Believe it or not, tankless water heaters have been around for a long time. In 1868, a painter from England named Benjamin Waddy Maughan invented the first tankless water heater called the geyser. It used hot gases to heat water flowing through a pipe and into a tub. Today tankless heaters work in a similar way but with added features like flue gas exhaust.
Tankless heaters can be installed centrally to provide hot water for the entire home or they can be installed at the point of use for a fixture or group of fixtures. They are sized based on the fixture flow rate and have a higher energy input than tanked equivalents because of how quickly the water is heated.
Why go tankless?
Tankless water heaters are ideal for a number of reasons. Whether you want one central heater or multiple point-of-use heaters, here are the reasons to go tankless:
You save energy by not having to keep 60 gallons of water hot all day while the house is empty. Tanked heaters also have losses through the tank walls, further adding to the energy consumed.
There’s no wait time for water to reach the right temperature in a tank. Water has a high heat capacity, which means that it needs a lot of heat to raise the temperature by one degree. In a tank situation, this means time waiting for the water to heat up if you happen to be the unfortunate one who gets in the shower last. Tankless heaters eliminate this problem by heating the water to the right temperature while it flows to you.
In addition to eliminating the wait times for heating a tankful of water, there’s no limit on how long you can run a tankless before the water gets cold. So even if you just finished a full load of laundry and need to wash the dishes, you’ll always have the hot water you need.
Tankless heaters are smaller and take up less room than tanked heaters. So if space is tight, you can reclaim an average of ten square feet of your home’s floor space for other important items.
They last longer than tanked heaters. Typical tankless heaters have a life expectancy of 20 years as opposed to the 10-15 years of tanked heaters.
