Gas water heaters are the most common choice in Okemos and across Greater Lansing, and most homes here already have the gas supply line in place. Whether you're doing a straightforward swap as part of a larger water heater replacement or installing gas for the first time, the installation involves more than swapping connections. The gas supply has to be sized correctly for the unit's BTU output, the venting has to match the combustion type, and everything gets leak tested before the unit goes into service. Our licensed plumbers handle all of it in one visit, whether you're in Okemos, East Lansing, Haslett, or elsewhere in Meridian Township, backed by the same 20 plus years of Mid Michigan experience behind every water heater we install.
What Goes Into Gas Water Heater Installation
Gas Supply
The gas line feeding your water heater has to be sized for the unit's BTU demand. Homes that have added gas appliances over the years sometimes have a main supply line that's near capacity, so we verify this before specifying a unit.
Venting
The venting type has to match the unit and the installation location. Atmospheric vent drafts naturally through a chimney flue with no electricity required. Power vent uses a blower to exhaust horizontally through PVC, giving more flexible placement. Direct vent is a sealed two pipe system that draws combustion air from outside, best for enclosed mechanical rooms.
Expansion Tank
Current code requires a thermal expansion tank when a pressure reducing valve is present on the water supply. Many older installations skipped this step. We include it whenever the situation calls for it.
When Gas Water Heaters Aren't The Best Fit
Gas is the default choice for most Okemos homes with an existing gas line, since it recovers faster and typically costs less to run than electric. If your home doesn't have gas service, or the gas line would need significant upgrading to support a water heater, an Electric Water Heater Installation skips that cost entirely since it only needs the right circuit and voltage at the tank's location. If floor space is tight or your household runs through hot water faster than a standard tank can keep up, a Tankless Water Heater Installation heats water on demand instead of storing it, though it comes with its own sizing and gas line considerations.
Our Installation Process
Evaluate Your Setup
Site visit to assess existing gas supply, venting, and available space, and confirm whether current venting can be reused or needs updating for the new unit.
Pull Permits & Prep Connections
Pull required permits and run new gas line or venting if needed.
Install & Connect
Remove the old unit if applicable and make all gas and water connections.
Test & Verify Safety
Run the unit through a full heating cycle and perform a gas leak check at every connection with professional detection equipment, no exceptions.
Gas Water Heater Installation Cost in Okemos, MI
Cost depends on the unit size and efficiency rating, whether existing venting can be reused, and whether any gas line work is needed. Most gas water heater installations in Okemos run $2,500 to $5,000 or more, with larger, higher-capacity units and jobs requiring new venting or gas line work landing at the higher end.
If your unit is old, leaking, or failing outright rather than needing a simple repair, a full replacement is usually the better value. Call (517) 742-2848 for pricing based on your specific home.
Why Choose Plumbing by Custom Built
Gas appliance installation requires a licensed plumber, and the safety check at the end is not optional. Carbon monoxide issues from improperly vented water heaters are silent and serious. We take the venting and leak verification steps on every gas job without exception, and we will not sign off on an installation we are not confident in.

FAQs
How long does a gas water heater installation take in Okemos, MI?
A standard replacement with existing venting in good condition typically takes two to three hours. Installations requiring new venting or gas line work take longer.
What size gas water heater do I need in Okemos?
Tank size is based on your household's peak hot water demand, not just the number of people. We assess your actual usage and recommend accordingly rather than just matching the old unit's size
Do I need a permit for gas water heater installation in Okemos, MI?
Yes. Gas appliance installations require a permit and inspection. We handle the permit and coordinate the inspection as part of the job.
What is the difference between atmospheric vent, power vent, and direct vent in Okemos?
Atmospheric vent exhausts through a chimney flue with no electricity needed. Power vent uses a blower and exhausts horizontally through PVC, which gives more placement flexibility. Direct vent draws combustion air from outside through a sealed two-pipe system and is best for enclosed spaces. We recommend the right type based on your installation location.
Does a new gas water heater actually lower my utility bill?
Most Energy Star gas units recover faster and use less fuel per gallon heated than older standard efficiency models, so replacing a unit older than 10 years typically shows up as a noticeable drop in your gas bill within the first year.
