Rheem Tankless Water Heaters in Cypress & Houston
Tony's Plumbing installs and services Rheem tankless water heaters in Katy, Cypress, and Houston. A Rheem tankless is not a one-for-one swap for a Rheem storage tank—gas, venting, and descaling still decide whether it keeps up.

What makes this page different: Households replacing a Rheem tank often ask for Rheem tankless; the fuel system, not brand loyalty, decides if that conversion works.
Rheem tankless is not a Rheem tank swap
A Rheem storage tank and a Rheem tankless share a name and almost nothing else about the install. The tankless unit needs more gas, a different vent, and a maintenance flush the tank never asked for.
Katy homeowners replacing a failed Rheem tank often want to stay with Rheem. We will install a Rheem tankless when the fuel system supports it, and a Rheem tank when it does not.
Venting and clearances on Katy homes
Rheem tankless venting has to terminate with the clearances the unit requires—away from windows, soffits, and the outdoor kitchen hood if the heater is on an exterior wall near a grill.
Garage installs in newer Katy houses still need combustion air and a condensate plan on condensing models. We walk that path before holes are cut.
Gas shared with grills and ranges
Cinco Ranch and other Katy villages often added a grill island to a meter that was sized for a tank, a range, and a dryer. A Rheem tankless on that same branch drops out when the grill and a shower run together.
Tony's Plumbing calculates the combined load and quotes a dedicated line when sharing is the reason hot water falls off. See our gas-line page for the piping scope.
Descaling a Rheem heat exchanger here
Rheem tankless heat exchangers scale in the same hard water that shortens tank life. Isolation valves and an annual flush are part of owning the unit in Cypress, Katy, and Houston.
Call (832) 890-8449 for Rheem tankless installation or a descale. Rheem tank replacement is quoted on its own page so the two jobs stay distinct.
FAQ
- Can a Rheem tank be replaced with a Rheem tankless?
- The Rheem name does not make it a one-for-one swap. Tony's Plumbing installs Rheem tankless in Katy, Cypress, and Houston when the fuel system can carry it, and a Rheem tank when it cannot.
- Will a Rheem tankless share gas with an outdoor kitchen?
- Katy grill islands plus a Rheem tankless often exceed the original branch. We quote a dedicated or larger line instead of letting the shower and the grill starve each other.
- Do you descale Rheem tankless heaters?
- Rheem heat exchangers scale the same way other tankless brands do here. We flush through the service valves and check flow before calling the unit failed.
