Gas Boiler Sizing Guide

Gas Boiler Sizing Guide for Cincinnati Homeowners

Proper sizing of your gas boiler means the difference between a comfortable winter’s night and frosty toes in the morning. If your boiler is too small, it will struggle to deliver the comfort you desire. It will also wear out sooner than it should. If the gas boiler is too large, you will waste energy throughout the year and negate any energy savings you might enjoy with an appropriately sized unit.

Contact National Heating and Air Conditioning Company at (513) 621-4620 for more information about the importance of boiler sizing and the steps we take to ensure your boiler is just the right fit for your home.

Why Gas Boilers Are a Good Choice For Your Home

Gas boilers are energy- and cost-efficient. Natural gas is a common, easy-to-source fuel, which makes it easy to install a gas boiler in Cincinnati homes. Gas boilers are eco-friendly and don’t require fuel storage. Over time, natural gas boilers will cost less to operate than other competing options, which means you will save money year after year; for the next 10 to 15 years, you can expect the boiler to provide efficient, effective operation.

Contact National Heating and Air Conditioning Company at (513) 621-4620 for more information about the advantages offered by natural gas boilers. It is our pleasure to answer your questions and help you identify the best boiler for your needs.

Sizing Your Boiler Up

Sizing your boiler should be done by a certified HVAC professional. A certified HVAC technician will calculate a wide range of factors, including the size of your home, the climate, and more. This information will provide the technician with the total cubic footage of the home. From this, they can calculate the appropriate number of British thermal units (BTUs) the gas boiler will need to produce to keep you comfortable.

Contact National Heating and Air Conditioning Company at (513) 621-4620 to learn how our team calculates the appropriately sized gas boiler for our clients. It’s our pleasure to give you an estimated BTU range so that you can start considering which boiler is most cost-effective and energy-efficient for your family’s needs.

Signs You Might Need a New Boiler

Your boiler will alert you to problems within the system. You will usually have sufficient warning that a failure is imminent. Common signs that a gas boiler is about to go kaput include the following:

  • Loud Noises: Banging, clanking, gurgling, thumping, and hissing are all signs that components are failing or sediment buildup within the tank is preventing efficient operation.
  • Thermostat Adjustments: If you are constantly adjusting your thermostat, it’s often a sign that your gas boiler isn’t working the way it should.
  • Yellow Flames: If you see yellow flames, it is a sign of improper combustion. This is a dangerous problem and could be releasing carbon monoxide gas into your home.
  • Repair Frequency: When you have your HVAC company on speed dial, it’s a definite sign that your gas boiler needs to be replaced.
