Tankless Water Heater Installation in Los Angeles

---

The cost of tankless water heater installation in Los Angeles depends on the equipment selected and the work required to convert your existing system. A tank-to-tankless conversion may require modifications to the gas line, water connections, electrical supply, venting, condensate drainage or installation location.

Grenier Construction can evaluate your existing water heater and provide a project-specific estimate for a complete tankless water heater conversion in Los Angeles.

Yes, many Los Angeles homes can be converted from a traditional storage-tank water heater to a modern tankless water heater.

Before installation, the home's existing gas supply, water lines, electrical availability and proposed water heater location should be evaluated. Grenier Construction can inspect your existing system and determine what modifications are needed for a proper tank-to-tankless conversion.

Yes. Many tankless water heater models are specifically designed for outdoor installation. Relocating a traditional water heater to an exterior-mounted tankless system can also free up valuable space inside a garage, basement, utility room or closet.

Exterior tankless water heater installations must meet the manufacturer's installation requirements as well as applicable clearances and local building requirements.

Not necessarily. Because gas tankless water heaters can have higher BTU demands than traditional tank water heaters, the home's existing gas system should be evaluated before installation.

The required tankless water heater gas-line size depends on the selected equipment, available gas pressure, pipe size and length, and the demand from other gas appliances in the home.

Grenier Construction can evaluate these conditions as part of planning your tankless water heater installation.

A hot-water recirculation system helps reduce the amount of time you wait for hot water to reach showers, faucets and other fixtures located farther from the tankless water heater.

Depending on the home's plumbing configuration and equipment selected, a tankless recirculation system may use a dedicated return line or a crossover valve installed beneath a kitchen or bathroom sink.

Recirculation can be particularly useful in larger Los Angeles homes where the water heater is located farther away from frequently used fixtures.

A tankless water heater heats water on demand, but that doesn't necessarily mean hot water will instantly reach every faucet. The heated water still has to travel through the plumbing between the tankless water heater and the fixture.

Installing a properly configured tankless water heater recirculation system can significantly reduce this waiting time and provide faster hot-water delivery throughout the home.

A tank-to-tankless water heater conversion in Los Angeles generally requires permitting, particularly when the project involves changes to gas piping, water connections, venting, electrical work or the water heater's location.

Grenier Construction can help coordinate the applicable tankless water heater permit and inspection process as part of the installation.

The project shown above was a one day install. However, the installation timeline depends on the existing conditions and scope of the project. A straightforward replacement may take less time than a complete tank-to-tankless conversion involving relocation of the water heater, new gas or water connections, electrical work or a hot-water recirculation system.

Grenier Construction reviews the installation scope and anticipated schedule with the homeowner before work begins.

The project shown above is a 160,000 BTU unit with more than enough heating capacity for two bathrooms, showers, tubs and kitchen needs. 

Tankless water heaters are generally sized according to the home's expected hot-water demand and required flow rate, rather than simply matching the gallon capacity of the old water heater.

The number of bathrooms, showers, sinks and appliances using hot water—as well as how many may operate simultaneously—should be considered when selecting a tankless system.

Grenier Construction can evaluate your home's hot-water needs and help determine an appropriately sized system for your installation.

The client received a $1,300 rebate for the Rinnai installation above.

Qualifying Southern California homeowners may be eligible for tankless water heater rebates when replacing a conventional storage-tank water heater with certain high-efficiency natural gas tankless systems.

Rebate amounts depend on the qualifying equipment and current utility program requirements.

Grenier Construction can help homeowners identify high-efficiency equipment options, while final eligibility and rebate amounts are determined by the applicable utility program.
