If you're tired of running out of hot water or watching your utility bills climb, a tankless water heater might be the answer. These systems heat water on demand instead of storing it in a tank, which means you get hot water instantly and only pay for what you use. Installing one isn't a simple DIY job though. It requires proper sizing, venting setup, and electrical or gas connections done right the first time.
At Plumbing Rosita, we handle the entire installation process from start to finish. We'll assess your home's hot water needs, recommend the right unit for your situation, and install it safely and efficiently. Whether you're upgrading from an old tank water heater or building new, we make sure your tankless system works reliably for years to come.
Tankless water heaters deliver continuous hot water flow without waiting. They take up less space than traditional tanks, can last 20+ years with proper maintenance, and often qualify for energy rebates. Most homeowners see lower monthly bills within the first year of installation.
We start by looking at your current setup, checking your home's water pressure and flow rate, and figuring out what size unit you actually need. A unit that's too small won't keep up if multiple fixtures run at once. One that's oversized wastes money. We get it right.
Depending on your unit type, we'll run new gas lines or upgrade electrical circuits. This has to meet code and handle the power demand safely. We inspect existing lines, add shutoff valves, and install all connections to spec.
For gas tankless heaters, proper venting is critical. We install the vent pipe to direct exhaust safely outside, usually through a wall or roof. The unit itself gets mounted securely where it won't freeze or take damage from weather.
We hook up hot and cold water lines with proper shut-off valves for future service. Dip tubes, temperature controls, and pressure relief valves all get installed according to the manufacturer's specs and local plumbing code.
Once everything's connected, we fire up the system and test for leaks, proper water temperature, and steady flow at multiple outlets. We walk you through how to use it, explain maintenance needs, and answer any questions you have about your new installation.
Some homeowners jump into buying a tankless unit without understanding their actual needs. Here's what goes wrong:
Tankless heaters need adequate flow to activate properly. If your home has weak water pressure from sediment buildup or old pipes, the unit may not heat efficiently. We check pressure before recommending a model.
Gas-fired tankless heaters demand more fuel flow than your current water heater. If your gas line can't handle it, installation won't work. We verify your gas service is sufficient and upgrade if needed.
Choosing a model based only on price or what a neighbor has usually backfires. Your home's peak hot water demand dictates the right GPM (gallons per minute) rating. Pick wrong and you'll constantly adjust temperatures or not get enough hot water.
Old galvanized pipes or mineral buildup can restrict flow and damage a new tankless heater's internal heat exchanger. We might recommend repiping services before installation for longevity.
