Things to Consider Before Purchasing a Tankless Water Heater
Tankless water heaters have special installation requirements.
1. Gas Supply - A 3/4” or larger gas supply pipe is required.
2. Venting - Some indoor models require Category III stainless steel venting purchased separately.
3. Gas Meter and/or Regulator - Must have enough capacity to supply all gas appliances in the home.
4. Isolation Valves - Make required periodic maintenance easier.
Reliance has many other high efficiency water heating options available. One of these may be a better choice for your application.
Peak Hot Water Demand
The next step is to determine how much hot water will be required during the busiest usage period (“peak demand”). To use the chart, consider all appliances and fixtures that use hot water, including lavatory faucets, kitchen faucets, washing machines, dishwashers, showers, and bathtubs. Be sure to determine how many appliances and fixtures will be used at the same time (“peak demand”).
