  • Digital display – Digital displays are a helpful feature, providing accurate temperature settings and maintenance codes.
  • Remote controls – Enjoy the convenience of a digital remote control to make changes to temperature settings.
  • Safety – Advanced sensors protect against overheating.

  • No flooding – There is risk of damage from flooding or leaks from a corroded or ruptured tank.
  • Longevity – Tankless water heaters can be expected to last more than twenty years, and easily replaceable parts extend life span.
  • Clean water – Water isn’t stored in a tank, absorbing contaminants, to ensure cleanliness.

What our customer are saying...


Kevin and Bryan did an awesome job installing my air handler HVAC system and HWT. They were professional friendly and knowledgeable. Ian who sold me the system was friendly and knowledgeable and knew about all the rebates and incentives available saving me thousands. T-Mark of West Seneca hands down is the best for HVAC/Plumbing service. I highly recommend them.
