Tankless Water Heaters

Endless Hot Water

Heating water only as it’s being used means you will never run out of hot water again. After the few seconds it takes for the water to reach the designated set temperature, our tankless water heaters will continually provide a steady flow of hot water for as long as your application needs it.

Compact Size

A tankless water heater takes up much less space than a conventional tank-type water heater. With no tank to steal valuable storage space, Seneca Plumbing’s wall-mount design allows for additional storage and flexibility.

Energy Conservation

Tankless water heaters from Seneca Plumbing provide you with continuous hot water in one of the most energy-efficient ways possible. Conventional tank-type water heaters will heat and store a set volume of water, regardless of whether someone is using that hot water or not. Because our water heaters only activate when hot water is being used, no standby energy losses are incurred, providing efficient heating and conserving gas energy.

A note regarding recommended service for your tankless water heater:

Tankless Heaters have proven themselves to be reliable over the years, requiring little maintenance or repairs. Most Tankless water heaters have a life expectancy of more than 15 years. Flushing the heat exchanger and periodic maintenance can significantly extend your water heater,s life and minimize loss of efficiency.

Water scale deposits are a significant cause of heat transfer loss, along with the subsequent increase in energy costs. In fact, even a thin layer of scale (1/32″) can cause a 30% increase in your cost of operation. Keeping the heating passages free of mineral deposits significantly improves efficiency, conserves energy and extends the life of the unit. We recommend this service every 3-4 years.

Western New York has a water hardness level between 6 and 12 grains. The federal government considers 6 grains and up as hard water.

We suggest the following services to help ensure trouble-free performance:

  • Heat exchanger flush
  • Cleaning or replacing the inlet filter
  • Checking the inlet gas pressure
  • Inspecting and cleaning the burner tray

The cost for this service is $189 plus parts plus tax.
