Tankless water heaters, also known as on-demand water heaters, provide hot water as needed rather than storing it in a tank. This can be a more energy-efficient option, as the water is only heated when it’s being used rather than constantly heating a tank of water.
Here are some things to consider when shopping for a tankless water heater:
- Size: Tankless water heaters come in a range of sizes, and it’s important to choose one that’s appropriate for your needs. Consider the number of bathrooms and appliances that will be using hot water simultaneously, as well as the climate in your area.
- Fuel type: Tankless water heaters can be powered by electricity, natural gas, or propane. Each type has its own advantages and disadvantages. For example, electric tankless water heaters are generally more energy-efficient, but they may not be suitable for homes with high hot water demand.
- Efficiency ratings: Look for a tankless water heater with a high energy factor (EF) rating, which indicates the efficiency of the unit. The higher the EF rating, the more energy-efficient the unit is.
- Flow rate: The flow rate of a tankless water heater refers to the amount of hot water it can produce per minute. Consider the flow rate when choosing a unit to ensure it can keep up with the hot water demand in your home.
- Warranty: Look for a tankless water heater with a good warranty. Many come with a limited lifetime warranty, which can provide peace of mind and protection in case of any issues.
- Professional installation: Tankless water heaters require professional installation, so be sure to factor in the cost of installation when budgeting for your new unit.
- Maintenance: Tankless water heaters require regular maintenance to ensure they are running efficiently and safely. Consider the ongoing maintenance costs when comparing different units.
By considering these factors, you can find a tankless water heater that meets your needs and budget.
