Rinnai Tankless Water Heaters: Endless Hot Water

Rinnai TanklessRinnai Corporation’s patented tankless water heating technology delivers hot water at up to 9.4 gallons per minute for as long as you need it. You can run a dishwasher, washing machine and take a shower without running out of hot water at any one source. This means no more cold showers! (View Impressive Tankless Product Animation!)

Rinnai is more efficient than standard storage-type water tanks because it only spends energy to heat the water you need, when you need it rather than constantly spending money and energy to needlessly heat and reheat gallons of water, as is done with storage-tank water heaters. A Rinnai tankless water heater can deliver savings of up to 50 percent on water heating costs when compared to traditional water tanks.

There are several models to choose from for any residential or commercial application, ranging from indoor to outdoor models, to natural gas or propane fired.


Additional controls are a great option for Rinnai Tankless water heater owners. Controls are the window to Rinnai’s tankless water heaters. They allow the user to view and interact with the water heater’s operation, and provide technical and service details for trouble free operation year after year.


All Rinnai interior units utilize an exclusive cool-to-the-touch vent system that is sealed combustion and requires only one penetration through the roof or sidewall. Rinnai interior units can mount almost anywhere and can have a vent up to 41 feet long. They are designed to operate at outdoor temperatures as low as -30° F.


Exterior Rinnai units offer tremendous flexibility and safety. They are mounted on the exterior of your home so they require no floor space. While they are designed to operate to -30°F, care should be taken to properly install them in colder climates.

Electric & Gas Tank Water Heater Replacement

When it’s time for a new electric or gas water heater, calling a professional will be the smartest thing you could ever do. We know how well water heaters can work and how safe they can be when properly installed. We also know the downfall and dangers of bad installations. That’s why we believe water heaters should only be installed by licensed and well trained professionals.

Water Heater HoustonAs of July 1, 2003 all conventional 30, 40 and 50 gallon residential gas-fired water heaters must comply with new, stringent standards regarding Flammable Vapor Ignition Resistance. Mammoth Plumbing utilizes the Defender Safety System, a cutting edge technology that fully complies with the new standard. You can count on Mammoth Plumbing to meet these requirements now and in the future.

Defender Safety System is only available to professional installers people whose knowledge, skill and experience ensure that the right model water heater is installed correctly. The peace of mind you realize by having Mammoth install your water heater is a priceless commodity you can get at a reasonable price.


Knowledge of Electricity and Its Uses: Installation of electric water heaters requires knowledge of the properly rated wiring material as well as knowledge of the home’s electrical capacity. An adequate electrical service is a requirement.


Getting the Right Gas Water Heater For Your Home: Gas valves are designed to handle a specific type of fuel. Some gas-fired water heaters are designed for certain types of homes. Making the wrong choice can be a serious hazard.

Thermal Expansion

Mammoth Understands Thermal Expansion: Do you have an open or closed water system? Closed systems are subject to thermal expansion and pressure build-up. Open systems can become closed when check valves, water softeners or water meters are added. A professional will add an expansion tank to avoid problems.

Pressure Build-up

Pressure Build-Up is a Serious Matter: Even if your water heater tank doesn’t rupture from thermal expansion, pressure inside the tank can cause a constriction of the flue tube. This, in turn, can cause a back up of combustion gases and carbon monoxide inside the home.

Specialty Heaters

Many Special Water Heaters Aren’t Sold To Customers: Certain Defender Safety System water heaters cannot be purchased by the public. There are literally thousands of models with important variations and safety features that you’ll never know about unless you call a professional such as ourselves.


Laws Governing Installations: In many parts of the country, state agencies and local municipalities have laws and codes governing the installation of water heaters. These laws state that a water heater must be installed by a licensed professional. Contact Mammoth Plumbing today to learn about all our plumbing services!


Time To Repipe?

A common issue plaguing homes in Houston is the need for whole home repiping. This is mainly due to deteriorating pipes made of galvanized steel and other low quality materials. Repiping a home is an involved process but a necessary one. Only fixing pipe leaks or replacing a few plumbing lines won’t resolve the issue long term.

Repiping a home isn’t easy and is a lot of difficult work. This is why only experienced trained plumbers from Mammoth Plumbing should complete repipe your home. With more than 25 years experience in the plumbing profession, Mammoth Plumbing has become one of the leaders of whole home repiping in Houston.

Signs a Home Needs Repiping

Discolored or Rusty Water

Discolored or rusty water indicates that the pipe material is breaking down and now saturates the water for showers, cloths washing, dish cleaning, ice making, toilet flushing, hand washing, and drinking. This can be hazardous to anyone in the home. The pipes will soon begin leaking or collapsing. A total home water line replacement is the only way to insure completely resolve this situation. This a common occurrence in the Houston area.

Galvanized, Iron, Zinc-Coated Pipes in Home

Decades ago, iron and galvanized pipes were common materials used for the water lines within Houston homes. These materials are beginning to fail due to their quick corrosion tendencies. The older the home with galvanized, iron or zinc coated pipes, the more likely a pipe with break, leak or cause discoloration. It would be a good idea to have your home repiped if these types of pipes are in your homes walls and floors.

Can’t Run More Than One Fixture at a Time

If the temperature of the water changes drastically when another fixture is turned on, it may be an indication of pipe deterioration. The hot water supply lines are usually the first water lines to corrode due to the heat accelerating the corrosion process.

Low Water Pressure

Low water pressure can be due to the constriction pipes experience as they corrode. This slows down water flow and prevents multiple fixtures from running at the same time.

Houston Repiping Materials

There are three main materials to be used when replacing the water lines of a home. Mammoth Plumbing has experience installing each type. Our master plumbers can determine which material is best used for each home and installation:

PEX (Crosslinked Polyethylene) – Excellent Temperature and Chemical Resistance. Flexible, Less Time Consuming Installation

Copper – Most widely used water piping material for the last 25 years nationwide. Excellent Temperature Resistance, Easy Installation

CPVC (Chlorinated Polyvinyl Chloride) – Excellent Temperature and Chemical Resistance. Increased Strength, Mild Flexiblity
