One of the features that make tankless water heating so popular is their ability to quickly ramp up to meet high demands for hot water. But with those high demands for hot water comes the need for a properly installed and sized gas line capable of meeting those demands. At Mechanical Hub, Bryan Cordill, director of residential and commercial business development for the Propane Education & Research Council, summarizes five tips that all pros should keep in mind to optimize tankless water heater installations.
The first tip? Make sure the line is sized correctly. “Properly sizing the gas line is critical to ensure a customer’s tankless water heater runs at optimal efficiency,” he writes. “Neglecting to consider the whole system load may leave your customers with an undersized and underperforming system.” These factors all play a role in determining the size of the gas line needed:
- Type of gas (propane or natural gas)
- Inlet pressure
- Total length of piping run
- Type and number of gas appliances in the home
- The maximum potential gas load of the whole home
