What to Know About Tankless Water Heaters

A Water Heater
Water heaters give you easy and fast access to hot water for cooking and cleaning. However, while many homeowners still choose traditional tanked systems, more and more people are considering tankless water heaters. Before you replace your old system, however, check out these facts to determine if a tankless system really is the right choice for you.

They Are Energy Efficient 

Tankless water heaters are also known as demand-type water heaters because they only start producing hot water when you turn on the hot water. With a traditional tanked system, hot water is stored in the tank, and energy is used to keep the water hot. A newer, high-end tank will have better insulation to naturally keep the water hot.

For this reason, traditional water heaters use energy even when you don't need hot water. You may go a full day without using much hot water, but the system is still using energy throughout the day to keep the water hot for you.

With a demand-type water heater, energy is only used when you need hot water. Once the hot water is activated, the heating elements begin to heat the water. On average, you may see savings of $44 to $108 in energy each year.

They Provide Unlimited Hot Water

While a tankless system is great for conserving energy, it isn't great at providing immediate hot water. Because the system doesn't start heating water until you need it, you may need to wait before the water reaches the desired temperature.

With a tanked system, however, you can also run out of hot water. If someone uses a lot of hot water, you can't use any hot water again until the tank refills and heats the water. Tankless systems don't run out of hot water (unless the system breaks or loses energy).

They Can Be Used for Single Faucets 

When choosing your tankless system, you can choose between whole-home and point-of-use water heaters. Whole-home water heaters may be best in existing homes because adding the necessary electric and/or gas lines can be problematic. A whole-home water heater uses one system, which sends hot water to every faucet in the house.

However, in some cases, a point-of-use water heater may be the better choice. If you only use hot water in certain locations, such as the kitchen and bathroom, you may want to install two point-of-use systems to save money.

Also, if your water heater (tankless or traditional) is installed far from some faucets, the water may lose heat before it reaches you. To solve this, many homeowners install a point-of-use system for these faucets to boost efficiency.  

They Still Require Maintenance  

Water heater tanks take a lot of maintenance because they store so much water. Sediment can collect in the tank, which reduces efficiency and increase the risk of damage or failure. For this reason, it's important to have your tank regularly flushed by a professional.

However, tankless systems also need to be maintained. Luckily, is often easier to maintain a tankless system because you don't need to worry about draining water. You'll need to have the system descaled by a professional, unless you have experience in safety cleaning tankless water heaters. If you live in an area with hard water, however, you may need maintenance more often.

Traditional tanked systems provide instant hot water, but they use a lot of energy to provide this luxury. With a tankless system, you can reduce energy spending because they only heat the water when you need it.
