Understanding tankless on-demand water heaters

How Does Tankless Work?

Tankless water heaters provide hot water only when you need it, which saves on your energy bill. Tankless water heaters also provide an endless supply of hot water which translates to a more comfortable shower for every individual in your home. An additional benefit includes space savings. Because there is no storage of water, tankless water heaters are significantly smaller than a traditional hot water tank.

Understanding On-demand

Tankless water heaters only supply hot water when there is demand. When considering a tankless water heater it is important to understand that these system provide on-demand hot water and not instant hot water. Depending on the existing piping within your home you will experience a slight delay in hot water supply. Once the hot water reaches the desired fixture the hot water supply will be endless.

On-demand water heater information

Water Heater Sizing

Tankless water heaters do not have significant water storage so it is important to install the appropriate size. Tankless water heaters are rated in gallons per minute or GPM. GPM needs are dependent upon daily routines and the types of fixtures installed in your home. To calculate GPM needs we will add up the GPM rating of all the fixtures or appliances which could be running simultaneously.
