How does a tankless water heater work?

A tankless or on-demand water heater heats water only when a faucet is turned on, rather than preheating and storing it. There is no storage tank, so water is heated on demand as it flows through the unit. Systems are sized to the home and number of occupants to get the most savings.

Does a tankless water heater lower utility bills?

Yes. A traditional tank preheats water and maintains its temperature regardless of use, while a tankless system ties energy use directly to demand with no preheating. Eliminating the standby heat loss of a stored, repeatedly reheated tank lowers utility bills.

How long does a tankless water heater last?

A tankless water heater can last 20 years or more, roughly double the 10 to 15 year lifespan of a conventional storage tank heater, which saves on replacement costs over time.

Is a tankless water heater worth the higher upfront cost?

A tankless system costs more to install initially, but when sized correctly for your household the energy savings and longer lifespan typically justify the difference. A proper assessment of your home and water demand helps determine the right configuration.

When It's Time To Replace Your Water Heater

Tankless water heaters are a step up from traditional hot water tanks. The concept is based on heating water only when faucets are turned on. There is no hot water storage, rather water is heated on demand only.

There are numerous configurations available, which are best created by consulting someone familiar with typical demands. That's why we suggest you call us for a discussion on your personal needs. Hot water on demand systems need to be fitted according to the size of your home and number of people living there to take full advantage of the savings it provides.

Hot water on demand is a little more expensive initially, but savings easily justify that when configured correctly to suit the needs in your home.

A Little Detail On Tankless Hot Water Systems

With the advancement in technology, you can have hot water on demand (when you need it) rather than waiting for a storage tank to heat up. There are many benefits of a tankless water heater over its predecessor.

With a tankless water heating system you do not have a storage tank. A conventional hot water tank preheats and stores 25 to 50 gallons of water which refills and heats up repeatedly.

On demand water heaters provide hot water only when you need it, doing away with storage tanks that cool down and consume energy needlessly.

Heating Loss

When water is preheated and stored in a tank, there is energy and heat loss. This can be avoided with on demand water heaters.

Utility Bills

Traditional water heaters pre-heat the fluid and maintain that temperature irrespective of your needs. With a tankless water system, your energy consumption is directly linked with your usage. There is no pre-heating involved. Hence, your utility bills are lower.

Life Span

Conventional water heaters last 10 to 15 years as compared to the almost double 20+ year life span of a tankless water heater, thereby saving on replacement costs over time.
