The tankless water heater is a relatively new type of heating system that has been on the market for about five years or less. Tankless means that the tank holds no water; the water flows in from somewhere else. Tankless water heaters – also known as instant, continuous flow, on-demand, water heaters – are water heaters that don’t hold any water in the tank; the water is heated instantly as it passes through the device and does not keep any water in the tank, only for what’s in the heat exchange coil. These devices are usually more energy-efficient than traditional tank water heaters (since they don’t waste energy when heating only part of the water). They are available in two basic types. One type is a closed-loop unit, which is the most efficient; the other type is an open-loop unit.
When selecting a tankless water heater, you need to consider how much hot water you use and whether your typical fuel (gas or electricity) is more cost-effective than alternative energy sources. Grand Prairie Plumbers find that installing these systems is beneficial, especially since they are energy efficient and require little maintenance. Tankless heaters include installation by a qualified plumber. This may be an expensive proposition, so if you are interested in installing one, make sure you understand the installation process, including any expected downtime due to any plumbing issues and how long it will take for your tankless heater to heat your water.
Tankless water heaters also save money. They use less space than standard tank heaters, meaning you may have less room for clutter inside of your home. This can be a great selling point should you decide to move. When you install a tankless water heater, you do not have to worry about the unit taking up valuable space in your house. The unit itself takes up very little space and can be moved almost anywhere.
You can also expect your energy consumption to be lower than with a traditional tank-style water heater. These units only heat the water as needed, which saves energy. On top of that, you won’t have to worry about being embarrassed at the sink when you need to wash the dish. In addition to energy savings, tankless water heaters are also safer than traditional units. A small gas tankless water heater typically contains no coolant, so they are far safer than their tank-style counterparts.
While most tankless water heaters get their temperature from the water temperature in your local area, some models will have a thermostat that can adjust the temperature based on your setting. This allows you to maintain a constant water temperature, even in extreme weather conditions. If you want to use your tankless water heater while in cold weather, but you don’t want the water temperature to drop too much, you can set the thermostat to a temperature that is closer to the normal room temperature.
The fact that tankless water heaters are much cheaper than conventional ones also helps make them a great buy. Since these units do not use a storage tank to hold the heated water, you do not have to keep an eye on the water temperature. As long as the tankless water heater has a regular supply of hot water, there is no concern about the water running out. And since tankless water heaters don’t use any fuel, you can expect to save hundreds of dollars on energy costs over the unit’s life. These pros definitely make tankless water heaters a good choice for anyone looking to save money and improve the quality of their home.
Some disadvantages of tankless water heaters do exist, however. One drawback is the consistent water temperature that they produce. Since the water is not turned on to the tank, it sits on the bottom and is not heated until you turn the hot water on. As you use the water, it warms up. It begins to rise, causing the water temperature to fluctuate and become unbalanced, which causes the consistent hot water during a power outage. To prevent this problem from ever happening, you should choose a model with a thermostat that automatically shuts off when the hot water reaches the desired temperature and turns it back on when the temperature has been successfully maintained.
So, although most tankless water heater models run just fine and don’t require much maintenance, there are some cons to consider as well. To minimize the chances of a major problem occurring, you may want to choose a dishwasher-style unit with a low-water detection setting. This will help ensure that you get as much hot water as you need, no matter how much water your dishwasher gets.
