Boiler Installation Services
Reliable Heating Solutions Installed the Right Way
A boiler is the heart of your home’s heating system. When it’s installed correctly, it delivers quiet, even heat, long service life, and dependable comfort through the coldest Chicagoland winters. When it’s installed incorrectly, it can lead to inefficiency, breakdowns, uneven heating, and costly repairs.
At RC Szabo Plumbing & Sewer, we specialize in professional boiler installation, from traditional cast iron boilers to high-efficiency boilers and modern combi boiler systems with AquaStat-controlled hot water tanks. Our approach is simple:
design the right system, install it correctly, and make it last.

Conventional Cast Iron Boiler Installation

Why Homeowners Choose Cast Iron Boilers

Lower upfront cost compared to high-efficiency models
Cast iron boilers are especially effective in homes with:

Radiators

Original hydronic piping

Consistent heating demand
When properly installed, these systems provide steady, reliable heat year after year.
High-Efficiency Boiler Installation
Improved Comfort & Lower Operating Costs
High-efficiency boilers are designed to extract more heat from fuel, reducing energy waste and monthly heating costs.
Benefits of High-Efficiency Boilers

Improved energy efficiency

Lower fuel consumption

More consistent indoor temperatures

High-efficiency boilers require precise installation, correct venting, and proper control setup to perform as intended—something our team handles every day.
Combi Boiler Installation
Heat + Hot Water in One Efficient System
A combi (combination) boiler provides space heating and domestic hot water from a single unit.
Advantages of Combi Boilers

Eliminates the need for a separate boiler and water heater

Saves space

On-demand hot water

Modern control options
For many homes, combi boilers offer a clean, streamlined solution—especially where space is limited.
Combi Boilers with AquaStat-Controlled Hot Water Tanks
Enhanced Hot Water Performance
In higher-demand households, a standard combi boiler alone may not be enough. That’s where AquaStat-controlled indirect hot water tanks come in.
Why Add an AquaStat Tank?

Increased hot water capacity

More consistent temperature

Better performance for multiple fixtures

Reduced strain on the boiler
The AquaStat monitors water temperature and signals the boiler to maintain optimal hot water availability without sacrificing heating performance.
This setup is ideal for:

Larger families

Multiple bathrooms

Homes with high simultaneous hot water demand

Common Questions About Water Softener Installation
How do I know which type of boiler is right for my home?
The right boiler depends on your home’s size, heat loss, existing piping, radiator or baseboard layout, hot water demand, and fuel type. We evaluate all of these factors before recommending a cast iron, high-efficiency, or combi boiler system.
Are combi boilers a good option for larger families?
Combi boilers can work well for many homes, but households with high simultaneous hot water demand often benefit from a combi boiler paired with an AquaStat-controlled indirect hot water tank for added capacity and temperature stability.
Will a new boiler heat my home more evenly?
Yes. Properly sized and professionally installed boilers provide more consistent heat, eliminate cold spots, and improve overall comfort compared to aging or improperly installed systems.
How long does boiler installation usually take?
Most boiler installations are completed within one to two days, depending on system complexity, piping modifications, and whether additional components such as indirect hot water tanks or zoning controls are included.
Can you replace my boiler without changing my radiators or baseboards?
In most cases, yes. Existing radiators or baseboard systems can often be reused as long as they’re in good condition and compatible with the new boiler. We evaluate this during the assessment process.
Do high-efficiency boilers really save money?
High-efficiency boilers can significantly reduce fuel consumption when properly installed and matched to the home. Savings vary based on usage, fuel costs, and system design, but many homeowners see noticeable reductions in heating expenses.
What causes boilers to short cycle?
Short cycling is often caused by improper sizing, incorrect piping, control issues, or poor system design. Professional installation and proper setup are essential to prevent this issue and extend boiler life.
Is boiler installation disruptive to my home?
We take care to minimize disruption. Our team works cleanly, protects surrounding areas, and completes the installation efficiently while keeping you informed throughout the process.
How long should a new boiler last?
With proper installation and maintenance, cast iron boilers often last 25–30 years or more, while high-efficiency and combi boilers typically last 15–20 years depending on usage and care.
Do you explain how to operate the new boiler after installation?
Yes. Once installation is complete, we walk you through system operation, thermostat use, basic maintenance expectations, and what to watch for so you’re comfortable using your new heating system.
