Are you working on being a socially conscious homeowner who goes beyond simply using rags instead of paper towels and calling it a day? A great way of going green while actually increasing the comfort and convenience of your home is to get rid of your old dinosaur of a water heater and opt for a new, tankless one. Not only does it provide the convenience of giving you hot water instantly, whenever you want it - which means you don’t have to worry about taking a cold shower anymore after your teen is done - it also uses much less energy.
Tankless means exactly what it says: no tank attached, so you don’t have to wait for gallons of water to heat up AND you don’t suffer the energy-wasting heat losses associated with the old style water heaters. A heating unit, either gas or electric, is located close to where the water is used and the water is only heated when it is needed. You can install multiple smaller tankless heaters where water is used (near the bathroom or laundry room), or you can opt for one of the newer whole house models.
Gas powered tankless heaters have higher throughput rates than electric ones, but can be a bit more costly to operate. If you use 41 gallons of hot water daily or less, you can see 24-34% more energy efficiency from making this switch. If you use more than that per day, your efficiencies will be less. The green secret is to install a tankless water heater while taking measures (such as using a timer while you are in the shower) to cut your overall hot water use.
According to the Energy Star site, installing a tankless water heater can save a typical family roughly 30% of their usual water heating costs. These units do tend to be a bit pricey ($600-900), but they last about 20 years and usually require lower maintenance. (A traditional water heater runs about $200 and lasts about 10 years.) As you can see, the payback period is much shorter on the tankless rather than the tank version because your saving so much more on your electricity bill! Being green and saving green; what more could you ask for?!
