Save Money With Tankless Water Heaters
Let ER Plumbing install a tankless water heater and you can save up to 50% on your water heating bills while enjoying an endless supply of hot water. We install residential and commercial tankless units of all makes and models.
How Will a Tankless Water Heater Save You Money?
Tankless water systems will save you money in the following three ways:
- Cost-efficiency, saving you up to 50% on your energy bills
- System longevity, as average tankless units last twice as long as conventional tank water heaters (20+ years)
- Energy-efficiency, even earning the ENERGY STAR approval rating (from the US Environmental Protection Agency and Department of Energy)
How Will a Tankless Water Heater Improve Your Quality of Life?
You’ll enjoy multiple quality of life benefits from your tankless system, including:
- Never-ending supply of hot water, even when running multiple appliances
- Never wait again after your other family members or guests shower
- More space, due to space-saving design
- Higher quality water, since rust and debris does not build up like in a tank

How do Tankless Water Heaters Work?
Tankless water heaters heat water on demand, reducing energy waste inherent in conventional tank water heaters, where water is kept hot and stored in a tank 24-7. You can buy small point of use tankless water heaters or whole house water heaters. Most tankless units are powered by gas, but some run on electricity.

Tankless Water Heater Repair Services
ER Plumbing not only installs tankless units, but repairs them as well.
Troubleshoot your tankless water heater by doing the following:
- Check the power source and reset the circuit breakers, if needed
- Reset the heater by turning off the breakers, then turning them back on
- Check the diagnostic code on the control board
- Check the temperature limit switch
- Check your thermostat
- See if your thermostat is working properly by increasing the temperature setting and testing for an appropriate water temperature adjustment
- Consider the fact that the unit may be undersized for the amount of hot water you require
- Look for evidence of leaks
- Check the water level requirements
It’s possible your tankless water heater may need any one of the following repairs:
- Leak detection and repair
- Flushing of the lines
- Replacement of switches or parts
- Wiring repairs, which should only be done by a professional as the voltage is too high for a do-it-yourselfer to take it on (usually around 240 volts)
