What makes tankless water heaters appealing? Mostly three things: a supply that does not run dry, lower standby energy use, and space. A tankless heater stays idle until you open a tap, then fires a high-output burner or electric element to heat water as it flows. With no stored water to keep warm, it wastes less energy between uses, and with regular descaling it can last two decades. It is not magic, though. Performance depends entirely on sizing and installation, which is where most of our work in Flint, MI goes.
The most important step happens before anything is installed. We total your peak demand in gallons per minute, such as a shower, a kitchen sink, and the dishwasher at once, and compare it against the temperature rise your incoming water needs in winter. That tells us the real capacity you need. Next we check the supply side. Gas tankless units fire at very high input, so a half-inch line that fed an old tank is often too small. Condensing models vent through PVC or polypropylene and need a condensate drain, while non-condensing units need stainless steel venting. Electric units bring their own demands, often needing multiple large breakers and sometimes a service upgrade.
Every tankless install from Flint Water Heater includes isolation service valves so future descaling takes minutes instead of hours, a clean gas connection with a sediment trap, correctly pitched and terminated venting, and a pressure relief valve piped to a safe location. If your water is hard, we talk through scale protection, since mineral buildup is what shortens tankless life most. We can add recirculation for faster hot water at distant bathrooms, set the temperature, handle permits where required, and walk you through maintenance before we leave.

Warning Signs to Watch For
Water heaters usually give plenty of warning before they fail, as long as you know what to look and listen for. These are the red flags our technicians see most often before a breakdown:
- A tank water heater that is ten years old or more and due for replacement
- A distant bath or detached space that needs its own hot water source
- Energy bills that reflect a tank heating water around the clock
- A utility area where a bulky tank takes up room you would rather use
- A home remodel or new build where the gas line and venting can be planned from scratch
- Hot water running out during back-to-back showers
- Adding a bathroom, soaking tub, or larger shower that needs more hot water
- Interest in a longer-lasting heater with replaceable parts
Don't Wait for a Total Failure
A little rust-colored water or a relief valve that drips now and then can be the first hint of a tank that is close to the end. Call Flint Water Heater at (810) 215-6528 at the first sign of trouble.

What a Trained Technician Brings to the Job
Buying the right unit is the easy part. The other half is making sure your home can support it. Gas tankless burners can fire at close to 199,000 BTU, so the size of the gas line, the capacity of the meter, and the pressure at high fire all have to check out. Vent materials, lengths, and terminations are dictated by the manufacturer and local code, and condensing units add a condensate drain that should be neutralized. Electric whole-home units can pull more current than an older panel can deliver. Get any of these wrong, and the unit underperforms or becomes unsafe.
Our job is to make tankless work the way it is supposed to. That starts with sizing for your busiest hour and coldest water, then making sure the home's gas, vent, and power can support it. We install with service valves for descaling, proper relief valve discharge, and venting built to the manual, then test under real demand before we leave. If a tankless unit is not the best choice for your home, whether because of cost, gas supply, or usage patterns, we say so and help you compare other options honestly.
From Your Call to Hot Water
We follow the same careful process on every water heater, whether it's a quick thermostat swap or a full tankless conversion. Here's what you can expect when you choose Flint Water Heater:
Demand Assessment & Sizing
We total the fixtures you run at the same time in gallons per minute and factor in winter inlet temperature, so the unit never falls behind in winter.
Infrastructure Review
We confirm the gas line and meter can feed the burner's full BTU demand, plan the right venting, and check the panel for electric units before any price is set.
Installation to Spec
The unit goes on the wall with service valves, a sediment trap on the gas line, correct vent pitch and termination, and a neutralized condensate line where needed.
Full-Flow Testing & Walkthrough
Before we leave, the heater runs with multiple fixtures open while we verify gas pressure, venting, and outlet temperature, then we explain descaling and error codes.

A few simple habits, like an annual flush and a quick look at the relief valve, can add years to a tank. Start with these practical measures our team relies on:
- Set the temperature around 120F for safety and efficiency
- Check and rinse the small filter screen at the cold inlet periodically
- Check the vent cap outside for nests, debris, or buildup
- Flush the unit with a descaling solution annually to keep scale off the heat exchanger
- Hard water shortens tankless life, so ask about scale protection
- If the unit shows a recurring code, note it and have it checked
- Do not cut power to a unit in a cold space, since its freeze protection needs electricity
DIY vs. Professional Tankless Water Heater Installation
The line between a safe DIY check and a risky repair is usually the moment you need to open a gas fitting, a vent connection, or an electrical cover. Here's a comparison:
| Consideration | DIY Attempt | Hiring a Pro |
|---|---|---|
| Sizing | Sized by the box, not your demand | Matched to real peak demand |
| Gas Supply | Old half-inch line reused regardless of load | Piping sized to the burner |
| Exhaust | Old flue reused or wrong vent material | Correct vent type, length, and termination |
| Power Needs | Overloaded circuits and tripped breakers | Panel and circuits confirmed before install |
| Future Service | No isolation valves, so descaling is a hassle | Scale protection discussed up front |
| Outcome | Possible warranty and permit problems | Steady hot water at real demand |
