What to Look for in a Propane Tankless Water Heater
When shopping for the best propane tankless water heater, several crucial factors come into play. Here’s what you need to keep in mind:
Flow Rate: This is measured in gallons per minute (GPM) and determines how much hot water the unit can provide simultaneously. Consider your household’s peak demand – do you often run multiple showers, the dishwasher, and the washing machine at once? A higher GPM rating ensures you’ll never run out of hot water.
Energy Efficiency: Look for units with high energy factor (EF) ratings. The higher the EF, the more efficient the water heater. This translates to lower operating costs and a smaller carbon footprint.
Size and Installation: Propane tankless water heaters are compact, but you’ll still need to ensure you have adequate space for installation. Consider whether you need an indoor or outdoor model, and check venting requirements.
Temperature Rise: This refers to how much the unit can increase the water temperature. In colder climates, you’ll need a heater capable of a higher temperature rise.
Durability and Warranty: Opt for models with robust construction and comprehensive warranties. Stainless steel heat exchangers often offer better longevity, especially in areas with hard water.
Smart Features: Some modern units come with Wi-Fi connectivity, allowing you to monitor and control your water heater remotely. This can be particularly useful for vacation homes or rental properties.
By keeping these factors in mind, you’ll be well-equipped to choose a propane tankless water heater that meets your specific needs and ensures a steady supply of hot water for years to come.
Pro Tip: Before making your final decision, calculate your home’s peak hot water demand. Add up the flow rates of all fixtures and appliances you might use simultaneously to ensure your chosen water heater can handle the load.
