FAQs

How does a tankless water heater work?

A tankless water heater operates by heating 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 instantly. As a result, tankless water heaters deliver a constant supply of hot water without the energy losses associated with keeping a large tank of water hot continuously.

What are the advantages of a tankless water heater?

The primary advantages include significant energy savings, as they only consume energy when hot water is needed, eliminating standby heat loss. They provide an unlimited supply of hot water, are compact and save space, have a longer lifespan than traditional tank heaters, and can lower monthly utility bills. Many modern units also offer advanced features like digital temperature control and remote monitoring.

How long do tankless water heaters last?

Tankless water heaters generally have a significantly longer service life compared to traditional storage tank water heaters. While a standard tank model may last 10 to 15 years, a tankless water heater can often operate efficiently for 20 years or more. Their longevity is attributed to the reduced corrosion and sediment buildup since they do not store water. Proper maintenance, such as periodic descaling, is crucial to achieving this maximum lifespan.

Are tankless water heaters more efficient?

Yes, tankless water heaters are markedly more energy-efficient than conventional storage tank models. Because they heat water on demand, they avoid the standby energy losses that constantly occur with a tank system. This can result in energy savings for households, though the exact amount saved depends on factors like daily hot water usage and the efficiency of the unit being replaced. Many tankless models meet strict Energy Star guidelines for efficiency.

What is the downside of a tankless water heater?

The main downsides include a higher initial purchase and installation cost compared to traditional tank heaters. The installation can be complex, potentially requiring upgrades to a home's electrical system for electric models or gas line and venting for gas models. Some users may experience a slight delay in hot water delivery, known as a cold water sandwich effect. Additionally, their output can be limited if multiple hot water outlets are used simultaneously without a properly sized unit.

Can a tankless water heater run out of hot water?

A properly sized tankless water heater is designed to provide a continuous flow of hot water and will not run out in the way a storage tank heater can. However, its capacity is limited by its flow rate, measured in gallons per minute (GPM). If the demand for hot water exceeds the unit's maximum GPM rating?for example, if showers, a dishwasher, and a washing machine are all running at once?the system may struggle to heat the water adequately for all outlets simultaneously.
