Choosing the Right Water Heater for Your Home

Water heater installation in Palatine starts with picking the right unit, and that decision involves more than just matching the size of what you’re replacing. Household size, hot water usage patterns, available fuel source, and the space where the unit will be installed all factor into which type and capacity makes the most sense. A unit that’s too small for the household will run out of hot water during peak demand. One that’s oversized costs more to operate than necessary. We’ll ask the right questions before recommending any equipment so the unit we install is genuinely matched to how your household uses hot water.

Tank vs. Tankless: Understanding the Difference

The choice between a traditional tank water heater and a tankless system is one of the most common questions we field during water heater consultations. Tank water heaters store a set volume of heated water and are ready to deliver it on demand. They have lower upfront costs and are straightforward to install in most homes. Tankless water heaters heat water on demand rather than storing it, which eliminates standby heat loss and delivers an unlimited supply of hot water as long as the unit isn’t overtaxed. They cost more upfront and may require upgrades to gas lines or electrical service, but they last significantly longer and deliver lower operating costs over time. We’ll walk you through both options honestly based on your home and budget.

What the Installation Includes

A Five Star water heater installation covers the full scope of the job. We remove and dispose of the old unit, install the new one, connect it to the existing gas or electrical supply and plumbing lines, verify proper venting on gas units, set the thermostat to a safe and efficient temperature, test the unit fully before leaving, and walk you through the operation and any maintenance the new unit requires. If we identify any issues with the existing connections, venting, or supply lines during installation, we’ll bring them to your attention with options before proceeding.

Permits and Code Compliance

Water heater installations in Illinois require a permit in most jurisdictions, and the work must meet current plumbing and mechanical codes. Five Star handles the permitting process and ensures every installation is code compliant. This matters not just for safety but for insurance purposes and for resale, where unpermitted work can create complications during a home inspection.

Frequently Asked Questions
How long does a water heater installation take?
A standard tank water heater replacement is typically completed in two to three hours. Tankless installations take longer, particularly if gas line or electrical upgrades are needed, and may require a half day or more depending on the complexity. We’ll give you a realistic time estimate as part of your upfront quote so you can plan accordingly.
For tank water heaters, capacity is typically measured in gallons and matched to household size. A household of one to two people generally needs a 30 to 40 gallon unit, while larger households of four or more typically require 50 gallons or more. For tankless units, sizing is based on flow rate and the number of simultaneous hot water demands the household places on the system. We’ll size the unit correctly during your consultation rather than simply matching what you had before.
For many households, yes. Tankless units last significantly longer than tank models, typically 15 to 20 years compared to 8 to 12, and they eliminate standby heat loss, which reduces operating costs over time. The upfront investment is higher and some homes require additional work to accommodate the unit. Whether the math works in your favor depends on your household’s usage, how long you plan to stay in the home, and what upgrades if any are required. We’ll give you a realistic picture of both options so you can decide based on actual numbers.
