Why Choose a Tankless?

Traditional water heaters with storage tanks constantly heat and reheat water, even when it's not being used. This results in wasted energy and higher utility bills. Tankless water heaters, on the other hand, only heat water when it's needed, making them more energy-efficient and cost-effective. Spot On Plumbing of Tulsa Plumbers can help maintain and provide you options so you can choose what's best.

Point of Use Tankless

Point of use tankless water heaters are small, compact units that are installed near the point of use, such as under a sink or in a bathroom. These are ideal for homes with limited space or for those who only need hot water in specific areas of the house.

Tips for Choosing a Tankless.

When choosing a tankless water heater, there are a few key factors to consider.

Fuel Type

Tankless water heaters can run on electricity, natural gas, or propane. Consider the availability and cost of each fuel type in your area before making a decision.

Flow Rate

The flow rate, measured in gallons per minute (GPM), determines how much hot water the unit can provide at one time. Consider the number of people in your household and their hot water usage habits when choosing a flow rate.


Tankless water heaters come in a variety of sizes, so it's important to choose one that fits your space and hot water needs. Point of use tankless water heaters are smaller and more compact, while whole-house units are larger and require more space for installation.

Energy Efficiency

Look for a tankless water heater with a high energy efficiency rating (EF). The higher the EF, the more energy-efficient the unit is, resulting in lower utility bills.

Tips for Maintaining Your Tankless Water Heater

Proper maintenance is essential for keeping your tankless water heater running efficiently and prolonging its lifespan. Here are some tips for maintaining your unit.

Regular Flushing

Over time, mineral deposits can build up in your tankless water heater, affecting its performance. It's important to flush your unit regularly to remove these deposits. Consult your manufacturer's instructions for the recommended flushing schedule.

Check the Pressure Relief Valve
