Tankless Water Heater Installation in Shreveport, LA
Running out of hot water halfway through a shower is one of the trade-offs of a storage tank. A tankless water heater warms water as you use it, so the supply does not run dry the way a tank does.
Rinchuso's Plumbing and Heating Inc handles tankless water heater change-outs and new installations for homes and businesses in Shreveport. We work with all major brands, and every installation we complete is code-compliant and set up to run efficiently.

How Tankless Water Heaters Work
Instead of keeping a full tank of water hot around the clock, a tankless unit sits idle until someone opens a hot water tap. Water flowing through the unit passes over a heat exchanger that warms it on the spot, and the unit shuts off again as soon as the tap closes.
With no stored water to keep warm, there is no energy spent heating water that nobody is using. Tankless units are also compact and mount on a wall, which frees up the floor space a tank used to occupy.
Changing Out a Tank for a Tankless Unit
Switching from a tank to a tankless heater is more than a straight swap. A tankless unit often needs different gas or electrical connections, venting, and water line placement than the tank it replaces. Our plumbers plan those changes before the old heater comes out, so the new one goes in right the first time.
A change-out generally includes:
- Disconnecting and removing the existing tank heater
- Mounting the new tankless unit
- Connecting the water lines and the fuel or power supply
- Setting up venting where the unit requires it
- Testing the system to confirm steady hot water at your fixtures
New Tankless Installations
Building a home, adding on, or remodeling a kitchen or bathroom is a good time to go tankless, since the plumbing can be laid out for the new unit from the beginning. Remodeling and new construction plumbing has been part of our work for over 40 years, so we can fit a tankless heater into your plans without slowing the project down.
Tankless Systems for Commercial Properties
Businesses with steady hot water demand, from kitchens to restrooms to service areas, need a heater that can keep up through the workday. We install tankless water heaters for commercial clients as well as homeowners, and we size and place each unit around how the building actually uses hot water.
Keeping Your Tankless Heater in Good Shape
Tankless heaters last longest with regular care. Minerals in the water can leave scale inside the heat exchanger, which makes the unit work harder over time. Periodic maintenance clears that buildup, and treating your water before it reaches the heater can slow it down. Our full house water treatment system services are one way to do that.
If your tankless unit is already showing problems, such as error codes or water that will not stay hot, our water heater repair team services and repairs tankless models from all major brands.

What is involved in a tankless change-out?
The old tank heater is disconnected and removed, and the tankless unit is mounted on a wall. Then the water lines, gas or electrical supply, and venting are connected to suit the new unit. The system is tested before the job is finished.
How does a tankless water heater make hot water without a tank?
When a hot water tap opens, water flows through the unit and over a heat exchanger that warms it instantly. When the tap closes, the unit shuts off. Nothing is stored, so there is no tank of water to keep hot.
Do tankless water heaters need maintenance?
Yes. Mineral scale can build up inside the heat exchanger, so periodic maintenance to clear it keeps the unit running efficiently. We maintain and repair tankless heaters as well as install them.
Which tankless brands do you install?
We work with all major brands of tankless water heaters, and every installation is code-compliant for both residential and commercial properties.
