Tips & Recommendations

With over 30 years of experience in plumbing services, we’ve gathered invaluable insights into the care and maintenance of tankless water heaters. Here are some tips and tricks to ensure your tankless system operates efficiently and lasts longer.

Regular Maintenance

Just like any appliance, regular check-ups can prevent minor issues from becoming major problems.

 

Clean the Inlet Screen

Over time, debris can accumulate in the inlet screen. Cleaning them regularly ensures optimal water flow and heating efficiency.

 

Flush the System

At least once a year, flush your tankless system to remove any mineral build-up, especially if you have hard water.

 

 

Water Conditioner

At minimum a salt free filter or similar prior to water heater will help reduce mineral deposits in the heat exchanger maintaining your water heaters efficiency.

 

 

Water Filter

Installing a water filter prior to the water heater will catch sediments and trash, to help maintain consistent water flow.

 

Ensure Proper Ventilation

If your system uses gas, ensure that the venting is done correctly to prevent any carbon monoxide issues.

 

Adjust the Temperature

Don’t set the temperature too high. A moderate setting can provide comfortable hot water while saving energy.

 

 

Insulate Pipes

Insulating the hot water pipes can help retain the heat and deliver hotter water faster.

 

Consider a Recirculation System

If you notice a delay in getting hot water, a recirculation system can provide instant hot water and save water in the long run.

Commonly Asked Questions

How often should I service my tankless water heater?

It’s recommended to service your tankless water heater annually, especially if you have hard water. Regular maintenance ensures optimal performance and longevity.

 

What are signs that my tankless water heater needs repair?

Common signs include inconsistent water temperatures, reduced water flow, unusual noises, or error messages on the unit’s display.

 

How long do tankless water heaters typically last?

With proper maintenance, tankless water heaters can last 20-25 years, which is longer than traditional tank heaters.

 

Is it true that tankless water heaters provide instant hot water?

Not exactly. While they heat water on demand, there’s still a delay as the hot water travels through the pipes to your faucet.

 

Why is there a delay in getting hot water?

The delay is due to the time it takes for the cold water in the pipes to be pushed out by the newly heated water. A recirculation system can reduce this wait time.

 

Can I install a tankless water heater myself?

While some DIY enthusiasts might attempt it, professional installation is recommended to ensure safety, efficiency, and adherence to local codes.

 

Do tankless water heaters require special venting?

Yes, gas-powered tankless water heaters require proper venting to safely expel combustion gases. It’s crucial to follow manufacturer guidelines.

 

Can hard water affect my tankless water heater?

Yes, hard water can lead to mineral buildup inside the unit, reducing efficiency. Regular flushing can help, and in areas with very hard water, a water softener might be beneficial.

 

How do I know the right size of tankless water heater for my home?

Size is determined by the maximum flow rate you need (measured in gallons per minute) and the temperature rise required. Consulting with a professional can ensure you get the right fit.

Are tankless water heaters energy efficient?

Yes, tankless water heaters are generally more energy-efficient than traditional tank heaters because they heat water on demand rather than maintaining a tank of hot water.
