These are a perfect choice for people who want to save money on heating costs. Most units use 30 to 50 percent less energy than tank-based units. They can cost more upfront, however. If you have a lot of needs for hot water, it’s possible it will suddenly stop on you.
A tankless water heater may initially sound impossible to those used to traditional types. But this kind of hot water heater possible might be just what you need. This type of unit doesn’t heat a large reservoir of water, but instead heats water as it’s needed. Because they’re smaller than a traditional unit, you can fit them in a closet or crawlspace.
Another great option for tight spaces is an electric water heater. This unit doesn’t cost as much to purchase and install. It can fit in a small, confined space. Electric units also have a longer lifespan. They can be safer because there’s no risk of a natural gas explosion. Because there’s no pilot light, the flame won't accidentally blow out and leak gas.
Another energy-efficient option is the heat pump water heater. It works on a fundamentally different principle. It's like a refrigerator in reverse. A refrigerator takes heat from inside and dumps it into the room. A heat pump pulls heat from outside of it and uses it to create hot water inside a tank. They can be two to three times more efficient than traditional heaters. This is according to the U.S. Department of Energy. The average high temperatures in Irving, Texas, of Dallas County are in the 90s from June through September. So, a system that cools a room is appealing.
