How to Choose a Residential Gas Boiler

Tagged As:

Gas boilers use combustion to offer heat to your home, or water through a set of pipes which run outward from the boiler. Most gas boilers use natural gas, but some of them utilize propane. The ideal boiler for your residential project allows you to keep utility bills as low as possible while keeping your home warm and cozy for years to come.

Home Size

The size of your home directly influences what type of boiler you purchase. When looking through various types of gas boilers, note that the documentation which says that the square footage of space for which the boiler was developed to. Bigger is not always better, since a thermostat intended for a home with 3,000 square feet absorbs much more petrol than a boiler intended for a 1,000-square-foot residence, so keep your measurements as precise as possible. If you have to opt for a boiler that is slightly away from the house measurements, always purchase the marginally larger furnace, since a furnace that isn’t large enough will not be able to effectively heat the home.

Efficiency Rating

Not all furnaces are made equal. Always assess the efficiency rating to help refine your search. The gasoline burners within boilers burn gasoline, and the greater the efficiency rating of a boiler, the less gasoline it burners. Should you just take two stoves side by side which are intended to heat a home of 1,500 square feet, but one cooker has an 85-percent efficiency rating in comparison to another that’s a 95-percent rating, then the higher-rated cooker burns less gas to heat the home. Look for the highest level of efficiency when narrowing down your decision.

Contract Rates

HVAC (heating, venting and air conditioning) installations cannot be performed by do-it-yourself contractors. You have to employ a certified HVAC installer. When you are looking for contracts, then get as many quotes as possible to find the typical rate. Selecting from merely three options is not a wide enough range to make certain you have the best prices. Rather, ask 10 or more. Look at the experience of the individual. Check to find out if he is insured, has a clean history, is he using the BBB, and has a good reputation. Check resumes and interview possible candidates.


Check warranties. The longer the guarantee, the more value that the newest puts on its own components. Most producers should carry a eight- to 10-year limited warranty covering important appliance parts inside the boiler. Standard manufacturer warranties typically vary from the 18 months to two-year mark, while labor warranties vary between one and three years. Anything outside of these parameters means you are in your own financially, such as purchasing a used boiler and having a independent contractor install it for you without any guarantees attached. The more coverage, the better off you are.
