How They Work
Tankless water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water. However, a tankless water heater’s output limits the flow rate.
Typically, tankless water heaters provide hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute. Gas-fired tankless water heaters produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a tankless water heater to its limit. To overcome this problem, you can install two or more tankless water heaters, connected in parallel for simultaneous demands of hot water. You can also install separate tankless water heaters for appliances — such as a clothes washer or dishwater — that use a lot of hot water in your home.
Many homeowners, however, see benefits of a tankless water heater beyond energy savings.
Hot water on-demand
Tankless water heaters are known as demand-type water heaters, they provide hot water only as needed. They don’t produce the standby energy losses as the standard water heaters so in turn it saves you money! You also never run out of hot water!
Earth-friendly Benefits
Tankless technology allows maximum energy efficiency and reduces your carbon foot print.These heaters also save space with a compact design, last longer and are better for the environment because a rusty tank doesn’t end up in the landfill.
