High-Efficiency Boiler Installation & Replacement

If you have an older boiler, it’s a great time to consider upgrading to a modern, high-efficiency unit. One reason is that boilers can lose significant energy when they get too old. Another is that technologies have improved greatly over the last 15 years and more.

Consider that a standard modern boiler is about 80% efficient. That’s likely 10% more efficient than your current boiler when it was new. High-efficiency models are 90% efficient or higher. That’s thanks to more innovations, including a second heat exchanger that limits heat losses via the flue.

A new boiler is a smart investment because it will significantly lower your monthly costs. New boilers have a smaller physical footprint, operate more quickly, and provide faster and more robust heating.

FAQs

Here are answers to several of the most common questions about our boiler services throughout Greater Cincinnati. If you have additional questions, contact us at your convenience.

How often should I have my boiler serviced?

Our experts recommend scheduling boiler maintenance every year, like any major appliance. The best time to schedule a tune-up is in the fall before the cold weather arrives. Most boiler warranties require it as a condition of coverage. It also helps ensure safe operation and peak efficiency, while preventing unexpected breakdowns.

What is the difference between a boiler and a furnace?

Furnaces are forced-air systems that heat air and then distribute it through ducts. Boilers create either hot water or steam and distribute it through pipes to radiators, baseboard heaters, or radiant panels.

Furnaces are often more inexpensive initially, but boilers provide better value over their longer lifespans. Another advantage is that boilers don’t affect air quality and humidity the way furnaces do.

How long can I expect my boiler to last?

Boilers for home heating have long had a reputation for great durability and longevity. Well-maintained cast iron boilers can last between 20 and 30 years, while newer high-efficiency systems last between 15 and 20 years. Regular boiler maintenance is key to a long boiler life and preventing problems.

What Our Clients Are Saying

Brandon of National Heating did an excellent job servicing my AC. He is very thorough, knowledgeable, and professional. He discovered that the low outside temperature sensor had not been set up on my Evolution Connex Control and took care of it. I appreciated his top-notch service!

Thomas S.

Great company that I trust. Very thorough. I just had my air conditioner annual service. I used Help in the past. They always tried to upsell every opportunity they had. National Heating and A/C is the real deal from booking the appointment to the actual work. Every person I have dealt with is kind, knowledgeable, and…

Paul M.

I can highly recommend National (previously Nelson Comfort) Heating and Air especially if Sanjay is the company representative. He was beyond good in that he completely cleaned the outside unit and was very thorough with the ac equipment inside the house. He even destroyed a wasp nest that I had not noticed. Five stars for this…

Susan S.

Excellent experience all around. Communication from the company was timely and complete. My service technician Chad Wilson was very knowledgeable, efficient and helpful. I had a lot of questions, having just moved into a house with systems that were unfamiliar to me (geothermal, radiant heat). Chad answered all my questions and spent extra time helping me…

Mary C.

We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
