How tankless water heaters work

Tankless water heaters, also called demand-type water heaters, heat water only when you need it. When a hot water tap opens, cold water flows through the unit where powerful gas burners or electric elements heat it instantly before delivery to the fixture. There is no storage tank, so there is no standby heat loss.

This on-demand design makes tankless water heaters significantly more energy-efficient than traditional tank models. By eliminating the need to continuously maintain a tank of hot water, tankless units use less energy and deliver lower utility bills. They also provide an endless supply of hot water, never running out during long showers or back-to-back uses.

Installation considerations

Tankless water heater installation is more involved than tank replacement. Gas models require larger gas supply lines and specialized stainless steel venting that can withstand higher exhaust temperatures. Electric models may require upgraded electrical service to handle the high power demand of heating elements.

The installation location must allow for proper venting, gas supply, and access for maintenance. Outdoor installation is an option in mild climates, eliminating the need for venting altogether. Our plumbers evaluate your property and recommend the best installation approach.

Sizing and selection

Tankless water heaters are rated by the temperature rise they can achieve at a given flow rate. The right size depends on your incoming water temperature, desired output temperature, and the number of fixtures that may be used simultaneously. Whole-house units can supply multiple bathrooms and appliances at once.

Flow rate and temperature rise requirements determine whether a single unit or a multiple-unit system is needed for your property. Our team performs a thorough analysis to recommend the right configuration for your household or commercial hot water demands.

Long-term value

While tankless water heaters have higher upfront costs, they offer compelling long-term value. Energy savings of 20-30 percent compared to tank models typically result in a payback period of three to seven years. With a lifespan of 15-20 years, tankless units provide years of savings beyond the payback period.

Annual descaling maintenance is recommended to remove mineral buildup, especially in areas with hard water. This simple maintenance preserves efficiency and extends the life of the unit. Many manufacturers offer extended warranties when maintenance is performed by a qualified professional.

Frequently Asked Questions

Common questions about tankless water heaters.

Can a tankless water heater supply my whole house?
Yes, whole-house tankless units can supply multiple fixtures simultaneously. Proper sizing based on flow rate and temperature rise ensures adequate capacity for your household.
Do tankless water heaters work during power outages?
Gas tankless units require electricity for the control board and ignition, so they will not operate during a power outage unless you have backup power. Some models offer battery backup options.
How often do tankless water heaters need maintenance?
Annual descaling is recommended to remove mineral buildup, especially in areas with hard water. This maintenance preserves efficiency and extends the life of the unit.
