What is an On Demand Water Heater

What is an On Demand Water Heater?

Tankless water heaters, also known as on demand water heaters, have recently gained a lot of attention thanks to their many benefits.

Compared to traditional systems, these units are more energy efficient because they heat water only as it is needed. As you can tell, this is a more cost-effective method compared to heating and reheating water before storing it inside a tank. Going tankless also helps save space because you’ll no longer need to maintain a big storage tank.

Advantages of a Tankless Water Heater

What is an On Demand Water Heater1Standard water heaters often last eight to 12 years, but a tankless water heater can perform efficiently for 20 to 30 years. Since these units are made with high-quality materials and parts, they are less susceptible to leaks, rust, and other kinds of damage from wear and tear.

Thanks to its energy efficiency, a tankless water heater can help you save money over time. Electricity is only used at the time you’re using the water heater, and you’ll have an unlimited supply of hot water that’s available in seconds rather than minutes. In fact, with a tankless heater, you can save up to 20 percent on your water heating bill.

As mentioned above, going tankless helps you save lots of space in your home as it doesn’t require a massive storage tank. It can be installed on walls or outdoors. And even though you don’t have a large tank, you’ll still have more than enough hot water for several appliances and showers to simultaneously run.

This also means there is no possibility of flooding in case of a damaged or ruptured tank.

What Types of On Demand Water Heater Are There?

A tankless water heater installation can come in two types: a whole-house heater or point-of-use heater. Most homeowners choose point-of-use systems because of their small size. This kind of water heater installation can easily fit in a closet or under a cabinet. They heat water for only one or two outlets and help prevent loss of water because of lag time.

Lag time refers to the amount of time hot water takes before it comes out of your faucet. Lag time is much higher in bigger homes, with an on demand water heater sometimes taking several minutes. Although your bill might be reduced, your water consumption level will increase. This is something to consider if you’re planning to buy a new water heater or installing a tankless water heater replacement.

Unlike point-of-use units, whole-house systems are larger in size. They can operate multiple outlets at a time and are also more expensive.

Having an on demand water heater in your home offers lots of advantages indeed. For water heater repair or installation, only certified professionals should do the job. Unless you are a certified plumber with pro-level skills, never try to go DIY on heater-related tasks as it may cause more damage to your system.

Most tankless water heaters are available in home centers or plumbing specialty stores. To know which brand or model of water heater fits your needs, seek advice from your trusted plumber.
