A traditional tank water heater heats 40-75 gallons of water around the clock — whether you use it or not. A tankless unit heats water only when you turn on the tap. The result: endless hot water, a fraction of the energy cost, and a unit that lasts twice as long.

Understanding the technology helps you choose the right unit for your home. Here is exactly what happens when you turn on a hot water tap.
GPM — gallons per minute — is how tankless capacity is measured. Add up simultaneous hot water uses to find your home's peak demand.
Already have a tankless heater that is acting up? Most tankless faults are repairable: see tankless and tank water heater repair, or Navien tankless repair for Navien error codes and descaling.
Every GT Home Services tankless installation follows the same professional process — TSSA registered, properly permitted, and completed in one visit.
"GT installed our Navien same day. The technician was professional, explained everything, and the hot water has been perfect ever since. Best decision we made."
"Called at 9am with no hot water. New Rinnai tankless installed by 2pm. The rental plan is amazing — $37.99 a month and zero upfront. Could not be happier."
"We have 4 bathrooms and our old tank couldn't keep up. GT recommended the Rinnai RX199 — now everyone gets a hot shower and our gas bill dropped. Amazing."
"Very honest company. They could have sold me the most expensive unit but recommended the right size for our home. Installed perfectly. Highly recommend."
"The technician arrived on time, wore shoe covers, and cleaned up everything after. Professional from start to finish. Our Navien has been flawless for months."
"Switched from a 40 gallon tank rental to a Rinnai RX160. Gas bill down $35 a month. The rental plan means if anything goes wrong GT handles it. 10 out of 10."
