Why Go Tankless?

A tankless water heater heats water only when you turn on a tap, instead of keeping 40 to 80 gallons hot around the clock.

  • Endless hot water, sized for your household’s peak demand
  • Lower energy bills, with no standby heat loss
  • Space savings: a wall-mounted unit frees up floor space in a basement or utility room
  • Longer life: often 20 years with regular maintenance, compared with 8 to 12 for a typical tank

Tankless Installation

Sizing is what separates a great tankless install from a frustrating one. We size each unit based on how many fixtures run at once, the flow rate they need, and the temperature rise from New Jersey’s cold incoming water in winter. Installation includes gas line and venting upgrades if needed, and a condensate drain for condensing models.

Tankless Water Heater Repair

Common problems we fix:

  • Hot water that runs out quickly or isn’t hot enough
  • Water that’s lukewarm or fluctuates in temperature
  • Error codes, often from scale, venting or gas supply issues
  • Low hot water pressure from clogged filters or mineral buildup
  • Leaks around the unit or relief valve
  • Igniter or burner problems

Tankless Water Heater Maintenance

New Jersey’s hard water leaves mineral scale inside tankless heat exchangers, which reduces efficiency and triggers error codes. Annual maintenance includes descaling and flushing the heat exchanger, cleaning the inlet filter, inspecting venting and gas connections, and testing the pressure relief valve.

Rebates and Financing

As a PSE&G Trade Ally, we apply PSE&G instant rebates to qualifying high-efficiency water heaters, and eligible PSE&G customers can spread the cost over time with 0% on-bill repayment. We also offer financing through NEIF and JB Financing.
