Endless Hot Water When You Need It

Secure Tankless Water Heater Installation in Lansing

You can say goodbye to cold showers and bulky storage tanks when you choose a tankless water heater designed for endless hot water, lower energy bills, and compact installation. Tankless systems heat water on demand, delivering hot water to every faucet and appliance without the standby losses that drain efficiency in traditional tanks. In Lansing, where newer homes often have open floor plans and limited mechanical space, a wall-mounted tankless unit frees up square footage while cutting monthly utility costs by up to thirty percent.


Treadwell Mechanical - Heating & Cooling installs both gas and electric tankless models with precision venting, proper sizing, and electrical or gas line upgrades as needed. Older properties in surrounding areas may require service panel or venting modifications to support high-demand tankless operation, and our licensed technicians handle every step from permits to final testing. You'll enjoy consistent water temperature, reduced waste, and a system that lasts up to twenty years with annual flushing and maintenance.

Details That Matter Most

Before installation begins, a technician evaluates your hot water usage, number of bathrooms, and simultaneous demand to size the correct unit. In Lansing, most households benefit from units rated between six and nine gallons per minute, depending on whether you run multiple showers and appliances at once. Gas models require Category III stainless steel venting, while electric units need dedicated circuits and adequate amperage.

On installation day, Treadwell Mechanical - Heating & Cooling mounts the unit, connects supply and return lines, installs venting or upgrades electrical panels, and tests output temperature under load. Trained technicians verify proper combustion air supply for gas models and confirm that electric units reach target temperatures without tripping breakers. You'll receive instructions on annual descaling to prevent mineral buildup, a common issue in Michigan's moderately hard water.

Repair services address ignition failures, temperature fluctuations, and error codes caused by scaling or sensor faults. Our service vehicles carry common parts like flow sensors, ignitors, and heat exchangers, allowing us to restore function quickly and minimize downtime.

Why Locals Choose This Option

Homeowners considering tankless technology often have questions about costs, performance, and compatibility with existing plumbing. Below are the most common concerns we address during consultations.

How much does a tankless system cost to install?

Installation costs range from two thousand to four thousand dollars depending on fuel type, venting requirements, and electrical upgrades. Most Lansing homeowners recoup the investment through energy savings within seven to ten years.

Will a tankless unit work in an older home?
Yes, but older homes may need gas line upsizing, electrical panel upgrades, or new venting. We assess your current infrastructure and provide a detailed estimate before starting any work.
How often does a tankless system need maintenance?
We recommend annual flushing to remove mineral scale, especially if you have hard water. This service takes about an hour and prevents performance loss and premature failure.
Can one unit serve a whole house?

A properly sized whole-house unit handles multiple fixtures simultaneously. Larger homes in Lansing with more than three bathrooms may benefit from a second unit or a higher-capacity model.

What causes temperature fluctuations?
Fluctuations often result from scale buildup on the heat exchanger, a faulty flow sensor, or undersized gas supply. We diagnose the root cause and restore stable output during every repair visit.
