A tankless water heater doesn't store hot water — it heats it the instant you turn on the tap. That means you don't run out partway through the third shower, and you're not paying to keep 50 gallons hot all day while you're at work. For the right household, it's a genuine upgrade.
It's not automatically the answer for everyone, and we'll tell you that honestly. A tankless unit needs adequate gas supply and proper venting, and it has a hard ceiling on how many fixtures it can serve at once. A big family running two showers and the dishwasher at the same time needs a unit sized for that peak, or a second one.
There's a local wrinkle, too. Our Genesee County water is hard, and hard water scales up a tankless heat exchanger just like it coats a tank. The difference is that a tankless unit needs periodic descaling to keep its efficiency and its warranty. We build that into the plan, usually by pairing the install with a whole-house water softener.
We're certified for Rinnai and install other leading brands, sized to your home's real demand.
Is a tankless right for your home?
You keep running out of hot water
If back-to-back showers go cold, a properly sized tankless unit solves it — it delivers hot water continuously instead of draining a fixed tank and waiting to recover.
Your old tank is failing anyway
Replacement is the natural moment to consider tankless. If you're already buying a new heater, it's worth comparing lifetime cost and space savings before defaulting to another tank.
You want back your floor space
A tankless unit hangs on the wall in a fraction of the footprint. In a tight utility room or a smaller Flushing home, that reclaimed space is a real benefit.
Your energy bills bug you
A tank reheats itself day and night whether you use it or not. Tankless heats only on demand, which trims that standby loss — especially in a household that's out during the day.
You're building or remodeling
A renovation is the cleanest time to run the gas and venting a tankless needs. Planning it in from the start avoids retrofitting around finished walls later.
What's Included
- Tankless sizing based on your flow rate and number of fixtures
- Gas-line and venting upgrades where the unit requires them
- Wall-mounted install with clean copper/PEX and isolation valves
- Conversion from an old tank system, including safe removal
- Descaling setup and guidance for our hard water
- Registration and manufacturer-warranty walkthrough
Our tankless installation process
- 1
We measure your real demand
We count the fixtures you'd run at once and factor in our cold Michigan groundwater, which affects flow rate. That sets the unit size so you're never left short at peak.
- 2
We check gas and venting
Tankless units need more gas flow than a tank and their own venting. We verify your gas line is sized correctly and plan the venting before we commit to a model.
- 3
We install to spec
We mount the unit, run or upsize the gas and venting, tie in water lines with service valves, and set the controls — all to code and the manufacturer's requirements.
- 4
We build in hard-water protection
We install isolation valves for easy descaling and recommend a softener so scale doesn't choke the heat exchanger. This is what keeps efficiency and the warranty intact.
- 5
We test and show you the controls
We run it under load, confirm steady temperature, and walk you through the settings and the descaling schedule so you get the full lifespan out of it.
What Affects the Cost
A tankless install is more involved than swapping a tank, and the price reflects your home's existing gas, venting, and water setup more than the unit alone. Here's what we look at, quoted in writing before we start.
- Unit capacity and brand sized to your peak demand
- Whether the existing gas line can feed it or needs upsizing
- New venting requirements for the unit's location
- Water-line rerouting and isolation valves for descaling
- Any electrical needed for the unit's controls or ignition
- A companion softener to protect the heat exchanger
- Removal of the old tank heater if you're switching over

Frequently Asked Questions
Will one tankless unit keep up with my whole house?
It can, if it's sized right for your peak demand and our cold incoming water. Large households running several fixtures at once sometimes need a larger model or a second unit, and we'll size it honestly.
Does hard water hurt a tankless heater?
Yes. Scale builds on the heat exchanger and drops efficiency. Tankless units need periodic descaling, which is why we install isolation valves and usually pair the unit with a softener.
Is a tankless really cheaper to run?
It eliminates the standby loss of keeping a full tank hot around the clock, so it usually lowers water-heating energy use. The savings are biggest in homes that are empty during the day.
How often does it need descaling?
In hard-water areas like ours, roughly once a year is typical, sooner without a softener. We set you up for it during install and can handle the service on a schedule.
Is a tankless water heater worth it in Michigan?
For many Flushing homes, yes — you get endless hot water, a smaller footprint, and lower standby energy loss. The trade-offs are a higher upfront cost and, in our hard water, a need for periodic descaling. We'll walk you through whether it pays off for your household.
Do tankless heaters struggle with hard water?
They can — mineral scale builds on the heat exchanger and hurts efficiency. That's why we recommend a softener or a scheduled descaling routine here in Genesee County, and we set the unit up so maintenance is easy.
