Water Heaters With a Lot of Pluses

More Savvy Tips

My neighbor just had a compact water heater installed that hangs on the garage wall. I had never seen one before, so I asked Mike Maples, of MAPLEService, Inc., a Diamond Certified company, to tell me more about how they work. Known as "on-demand" water heaters, these devices have a number of advantages. They save energy because they do not keep a tank of water hot. When you turn on a faucet, a flow switch ignites the water heater. Another advantage is that you don't have to worry about flooding if your water heater springs a leak while you're away. On-demand units are safer in case of an earthquake. And finally, they last longer than a tank type heater. You do need a larger flu and gas supply to accommodate this type of heater, which adds to the cost of installation.
