Tankless water heaters deliver a constant flow of hot water on demand, though not instantly as cold water in the pipes must first be flushed out. Properly sized, they can serve several hot water appliances and plumbing fixtures simultaneously without needing the recovery time of a conventional tank heater.
1. Light the Candle
When hot water is needed at a tap or appliance, the heater responds and the unit’s preset temperature sensor triggers an electric heating element or gas burner.
2. Warm the Water
The burner quickly warms the heat exchanger above it. Water supply pipes tightly wrap the exchanger to warm the water and deliver it through the plumbing system.
3. Safe and Efficient
A sealed, dual-chamber pipe brings in and exhausts combustion air to maintain air quality. Once hot water is delivered, the unit shuts down, reducing energy consumption and carbon emissions.
