"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"John was outstanding! He meticulously diagnosed the problem and installed the equipment after tracking it down at 2 local supply houses. He kept us informed every step of the way and worked diligently until the work was completed. This is the second time we've asked Mull Bros. to perform a service at our house. We received excellent service both times. Mull Bros. is a highly professional company that has exceeded our expectations.

Install Boiler questions, answered by experts

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.
