Storage Tank

How a Tank Water Heater Works

A storage tank water heater keeps 40–75 gallons of water heated and ready at all times. A gas burner at the base (or electric elements inside the tank) maintains your set temperature around the clock. When you turn on a hot water tap, pre-heated water flows out immediately.

It's the most common type in West Michigan homes by a wide margin — and for good reason. They're simple, affordable, and easy to service or replace.

Advantages

  • ·Lower upfront purchase + install cost
  • ·Hot water available instantly at the tap
  • ·Works with any fuel type
  • ·Simple technology — easy to service
  • ·Large capacity for simultaneous use
  • ·Most installs completed same day

Limitations

  • ·Finite hot water — can run out
  • ·Heats water even when not in use
  • ·Takes up floor space in utility area
  • ·Shorter lifespan vs. tankless (10–14 yrs)
  • ·Standby heat loss over time

Who should choose a tank?

Most homeowners — especially if you're replacing an existing tank setup, want a straightforward same-day install, or prefer a lower upfront cost. A properly sized tank handles the hot water needs of the vast majority of West Michigan households without any issues.

On-Demand

How a Tankless Water Heater Works

A tankless unit heats water on demand as it flows through the unit — there's no storage tank to fill or maintain. When you turn on a hot tap, cold water travels through a heat exchanger and comes out hot within seconds. The supply is continuous: as long as you're running the tap, you have hot water.

Tankless units in the Grand Rapids area are almost exclusively natural gas or propane. They mount to the wall and take up a fraction of the space of a tank. The tradeoff is a higher installation cost and more complex venting requirements.

Advantages

  • ·Endless hot water — no tank to deplete
  • ·No standby heat loss
  • ·Wall-mounted — saves floor space
  • ·Longer lifespan: 20+ years
  • ·Compact, modern footprint
  • ·Only heats when you actually need it

Limitations

  • ·Higher upfront cost than a tank
  • ·Gas or propane only — not electric
  • ·Installation is more complex
  • ·May need gas line or venting upgrades
  • ·Cold water sandwich effect on short draws
  • ·Higher service/repair cost when needed

Who should choose tankless?

Homeowners who regularly run out of hot water, have a large household, plan to stay in their home long-term, or want to free up utility space. The economics make the most sense when the unit gets heavy daily use and you can recoup the installation cost over a longer lifespan.

FAQ

Common Questions

Can I switch from a tank to tankless in one visit?

It depends on your home's existing gas line size and venting setup. Tankless units often require a dedicated larger-diameter gas line and a new PVC venting run, which adds time and cost. In some homes it's straightforward; in others it requires more prep work. We'll assess your setup and give you an honest timeline before committing.

Is a tankless water heater available in electric?

Whole-home electric tankless units require extremely high amperage (often 150–200A dedicated) that most West Michigan homes aren't wired for. We install gas and propane tankless units only. If your home is electric and you want on-demand performance, we can talk through your options — including right-sizing a high-efficiency electric tank.

How long does a tankless water heater actually last?

With regular annual maintenance (mainly descaling the heat exchanger), tankless units routinely last 20–25 years. The main serviceable components — the heat exchanger, igniter, and flow sensor — can all be replaced individually, which is why the lifespan is so much longer than a storage tank.

What's a 'cold water sandwich' and does it matter?

A cold water sandwich is a brief burst of cold (or lukewarm) water that can occur when you turn a hot tap on and off quickly in succession. It happens because the tankless unit briefly re-fires and the residual warm water in the pipes is followed by a slug of cold before the unit heats up again. It's a minor quirk most people adapt to quickly, and it's less noticeable in larger households with more continuous hot water use.

Do tank water heaters really run out of hot water?

Yes — if back-to-back showers, laundry, and a dishwasher all run at once, a tank can be depleted. A properly sized tank for your household (which we help you select) minimizes this significantly. If you're frequently running out, it often means you need a larger tank rather than an immediate switch to tankless.

Which type is more expensive to repair?

Tankless repairs are generally more expensive — the parts (heat exchangers, control boards, flow sensors) cost more, and the diagnosis is more involved. That said, tankless units need repair less often and last longer. Tank repairs are cheaper per visit, but tanks are more likely to reach a point where repair isn't worth it.
