A tankless water heater works on a simple idea: instead of keeping 40 or 50 gallons hot around the clock, it heats water only while a tap is open. When water starts moving, a flow sensor notices, a powerful burner or electric element fires, and the water is heated as it passes through a compact heat exchanger. The upside is significant: no standby heat loss, hot water that does not run out during back-to-back showers, a wall-mounted unit that frees up floor space, and a service life that often reaches twenty years with maintenance. For plenty of South Lyon, MI households, that makes tankless a smart upgrade.
A good tankless install starts with math, not tools. 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 how much the unit must heat cold winter water. 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 models are their own case, often needing multiple large breakers and sometimes a service upgrade.
Every tankless install from South Lyon Water Heater includes isolation service valves so future descaling takes minutes instead of hours, proper gas piping with a drip leg, 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 the main enemy of a tankless heat exchanger. 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.

When to Call for Tankless Water Heater Installation
Recognizing the warning signs early can save you money and keep a slow drip from turning into a flooded utility room. Keep an eye out for the following:
- Standby losses on a tank that sits idle for long stretches
- An addition or guest suite that is a long run from the main heater
- Interest in a longer-lasting heater with replaceable parts
- A growing household or new bathroom adding hot water demand
- Renovation work that makes gas line and vent changes easier to fit in
- Showers turning lukewarm before everyone gets a turn
- Limited floor space in a closet, garage, or utility room
- An aging tank that has started to rust, rumble, or leak
A Slow Leak Never Stays Slow
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 South Lyon Water Heater at (947) 227-7625 at the first sign of trouble.

Why Professional Tankless Water Heater Installation Matters
Tankless installation is more involved than swapping a tank. A whole-home gas unit can demand several times the gas flow of a standard tank, and running it on an undersized line causes low flame, error codes, and lukewarm water. Venting is equally specific: condensing units use plastic vent pipe and need a condensate drain, non-condensing units need stainless steel, and neither can simply reuse the old tank's flue in most cases. Electric tankless can require multiple large circuits, and mistakes with gas, venting, or high-amperage wiring carry serious safety consequences.
We take the guesswork out of going tankless. That starts with sizing for your busiest hour and coldest water, then confirming your gas, venting, and electrical can support the unit. 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, because of cost, supply limits, or how you use hot water, we say so and help you compare other options honestly.
Our Tankless Water Heater Installation Process
We work through a clear, repeatable process so you always know what's happening and what it will cost. Here's how we handle tankless water heater installation from start to finish:
Demand Assessment & Sizing
Sizing starts with your peak demand in GPM and the temperature rise needed for cold winter water. That pairing tells us which unit will actually keep up.
Gas, Venting & Power Check
Gas line size, meter capacity, vent routing, condensate drainage, and electrical service all get checked, so the quote reflects the real job.
Careful Install
The unit goes on the wall with service valves, a sediment trap on the gas line, correct vent pitch and termination, and a condensate neutralizer where needed.
Startup & Verification
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.
Not Sure What You Need?
We give honest advice and upfront pricing on every job, big or small.

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:
- Write down any error codes and call early rather than resetting repeatedly
- In freezing weather, keep the unit powered and insulate exposed piping
- Clean the inlet water filter screen a few times a year
- Consider a water softener or scale-prevention filter if your water is hard
- Make sure the outside vent and intake are never blocked
- A setting near 120F limits scalding and reduces scale formation
- Descale the heat exchanger once a year, or more often with hard water
Doing It Yourself vs. Hiring a Technician
Relighting a pilot by following the label is one thing. Diagnosing a gas valve, a burned-out element, a dirty flame sensor, or a tankless error code calls for meters and know-how that a pro brings. Here's how the two approaches stack up:
| Consideration | DIY Attempt | Professional Service |
|---|---|---|
| Capacity | Sized by the box, not your demand | Sized by GPM and winter temperature rise |
| Gas Supply | Old half-inch line reused regardless of load | Line and meter verified for full BTU demand |
| Exhaust | Clearances and pitch overlooked | Condensing or stainless venting done properly |
| Electrical | Wiring undersized for the load | Service upgrades flagged up front |
| Future Service | No isolation valves, so descaling is a hassle | Built for easy annual service |
| Result | Lukewarm water and error codes | Steady hot water at real demand |
