Has the time come to upgrade your home's water heating system? The choice to convert to a tankless water heater can be a game-changer. However, before making a final call, you should consider various factors that will ensure you make an informed decision. Below, we will examine key aspects to consider when contemplating a switch to a tankless water heater for your home.

1. Energy Efficiency and Cost Savings

One of the top reasons homeowners consider switching to tankless water heaters is their energy efficiency. Unlike traditional water heaters, tankless models only heat water as needed, eliminating the energy wasted on constantly reheating water in a storage tank. This efficiency often results in significant cost savings on energy bills over time.

The Department of Energy reports that tankless water heaters can be up to 34% more energy-efficient than conventional storage tank models! This translates into long-term savings for homeowners.

2. Hot Water Demand

Assessing your household's hot water demand is crucial before switching to a tankless water heater. Tankless models provide a continuous supply of hot water, but their capacity is limited. Consider your home's number of bathrooms, appliances, and fixtures that require hot water simultaneously in your home.

If your household often experiences high demand for hot water, such as multiple showers running simultaneously, a two tankless water heaters may be the ideal solution, perhaps one for bathrooms and one for the kitchen and appliances.

3. Installation Considerations

Switching to a tankless water heater requires professional installation. Some key installation considerations include:

  • Gas or electric: Determine if you have access to a natural gas line or if an electric model is more suitable for your home.
  • Space requirements: Tankless water heaters are compact and can be installed in various locations, such as wall-mounted or outdoors.
  • Water flow rate: Ensure your home's plumbing system can support the required flow rate for the tankless water heater.

4. Long-Term Durability and Maintenance

Tankless water heaters are known for their longer lifespan when compared to traditional storage tank models. That said, regular maintenance is still required to ensure optimal performance and prevent potential issues.

Consider the maintenance requirements of tankless water heaters, such as descaling to remove mineral buildup, and factor in the associated costs and frequency of maintenance visits. Additionally, research the warranty options provided by manufacturers to safeguard your investment.

5. Environmental Impact

Reducing your carbon footprint is increasingly important. Tankless water heaters contribute to environmental sustainability by conserving energy and reducing greenhouse gas emissions. You can contribute to a greener future by converting to a tankless water heater.


Switching to a tankless water heater offers numerous benefits, including energy efficiency, cost savings, and a continuous supply of hot water. However, it's crucial to consider factors such as hot water demand, installation requirements, maintenance, and the environmental impact before making a decision.
