Benefits of Installing a Boiler
You may find some folks who prefer their furnace to a boiler, but if you have a boiler in your home, you likely recognize the benefits.
- Cost: With a home heating boiler, your operating costs can be much lower than typical heating systems. Although the installation of a new boiler is typically more expensive than a furnace, you could save yourself some cash in the long run.
- Clean heat: Boiler heating systems are a clean form of heating that doesn’t produce dust particles or other allergens. Since a boiler heating system uses hot water that radiates through your home instead of blowers, you’re not kicking up any dust or airborne pollutants. Your allergies will thank you!
- Longevity: Although the age of your boiler depends highly on how well-maintained the system remains, many of our Classic Aire Care service technicians are still performing maintenance on boilers that have been around for decades! Boilers need maintenance just as much as common furnaces. Occasional parts may need replacing to extend the life of your boiler.

Boilers vs. Furnaces: What’s the Difference?
Boilers, like furnaces, use gas, oil, or electricity to generate heat throughout your home. The main difference between a boiler and a furnace is what is used to transfer the heat. A furnace uses a blower across heated coils to push air through the ductwork in your home. A boiler heats up water and transfers it to radiators or baseboard heaters inside your home through pipes.
Many Classic Aire Care customers prefer their boilers because they don’t require ductwork to be installed in their homes. In addition, our customers often find the humidity levels in their home remain comfortable in the winter, resulting in them feeling warmer for longer during the winter months.
Types of Boilers We Can Service
At Classic Aire Care, our technicians are trained and certified to work on all types of boilers. Whether you have a gas, electric, or solid fuel boilers, we’re here to help!
Gas Boilers
Gas boilers are the most common type, and Classic Aire Care technicians work on these the most. Gas boilers are extremely durable and incredibly efficient. Many gas boilers send heater water to the radiators, while many heat the water and only send steam to the radiators instead of hot water.
Electric Boilers
Electric boilers use the same process to heat your home, except they use electricity to heat the water instead of gas. Many gas boilers require a flue or chimney to dispose of waste gases. Because the electric boiler does not need to dispose of waste gases, it doesn’t require a flue or chimney, making it cheaper to install while keeping its durability.
Solid Fuel Boilers
Solid fuel boilers are starting to pop up more and more. With its earth-friendly fuel, many new homes can be built with a solid fuel boiler that keeps your home just as comfortable without using gas or electric. Solid fuel boilers often use a form of pellet made out of wood that is often made of recycled materials. The pellets are readily available and the cost to operate is usually less since it uses recycled material instead of fossil fuels.

Frequently Asked Questions
What are the benefits of a boiler heating system?
Boiler heating systems offer superior comfort and efficiency for St. Louis homes. Unlike forced-air systems, boilers provide consistent, even heat distribution through radiant heating, eliminating cold spots and drafts. They operate more quietly than traditional furnaces and don’t circulate dust or allergens, making them ideal for allergy sufferers. Boilers typically last 15-30 years, longer than most furnaces, and maintain high efficiency ratings throughout their lifespan. Modern condensing boilers can achieve 90-95% efficiency, reducing energy costs during Missouri’s cold winters while providing reliable, comfortable heating.
What are the different types of boilers?
The main boiler types include gas boilers, oil boilers, and electric boilers. Gas boilers are most popular in the St. Louis area due to natural gas availability and cost-effectiveness. Condensing boilers offer the highest efficiency by capturing heat from exhaust gases. Combi boilers provide both heating and hot water in a compact unit, perfect for smaller homes. System boilers work with separate hot water tanks for larger households. Steam boilers use steam distribution, while hot water boilers circulate heated water. Our Classic Aire Care experts can recommend the best boiler type based on your home’s size and heating needs.
How do I know if my boiler is leaking?
Signs of boiler leaks include water puddles around the unit, decreased water pressure on the gauge, unusual sounds like dripping or hissing, and increased water bills. Check for water stains on walls or ceilings near the boiler location. Rusty or corroded components around the boiler often indicate moisture problems. A sudden drop in heating efficiency or cold radiators may also signal internal leaks. If you notice any of these warning signs in your St. Louis home, contact Classic Aire Care immediately. Boiler leaks can cause significant water damage and safety hazards if left untreated.
What should I do if my boiler is making strange noises?
Strange boiler noises often indicate specific problems requiring professional attention. Banging or kettling sounds typically mean mineral buildup or overheating. Gurgling noises usually indicate air trapped in the system or low water levels. Whistling sounds may signal a faulty valve or pump issue. Rumbling noises can indicate sediment buildup in the heat exchanger. Turn off your boiler if noises are accompanied by unusual smells or visible leaks. While some minor noises are normal, persistent or loud sounds warrant immediate inspection. Contact Classic Aire Care for professional boiler diagnosis and repair in the St. Louis area.
