Whether you’re a homeowner exploring an upgrade or a contractor installing high-efficiency systems, tankless water heaters continue to grow in popularity for their energy efficiency, compact size, and ability to provide instant hot water. But while the water heater itself is the star of the system, proper venting is just as essential for safety, reliability, and long-term performance.
That’s where Centrotherm, a North American leader in high-efficiency venting solutions, comes in. Centrotherm provides safe, durable, and code-compliant venting systems for tankless water heaters, condensing boilers, and furnaces, ensuring both homeowners and contractors have confidence in their installations.
How Does a Tankless Water Heater Work?
A tankless hot water heater heats water only when it’s needed, instead of storing it in a tank. For example, when someone turns on a shower, cold water flows through the unit’s heating elements and is instantly brought up to temperature. This eliminates standby heat loss and provides an endless supply of hot water.
For contractors, proper venting is central to this process as high-efficiency heating appliances produce acidic condensates. Centrotherm’s InnoFlue® Safe Flue Gas Venting and particularly, AcidiRID neutralizes these condensates, managing this exhaust safely, protecting the home while helping contractors meet building codes and installation requirements.

Tankless systems activate only when hot water is required. This saves energy for homeowners and allows contractors more flexibility in installation locations due to smaller footprints and fewer constraints than traditional tanks.
Benefits of Instant Hot Water
Homeowners enjoy immediate comfort and reduced water waste. Whilst contractors appreciate installing systems that lead to fewer call-backs due to performance concerns, especially when paired with Centrotherm’s safe flue gas venting solution.
