"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Hello, Yellow Dog Home Services was phenomenal! Jeffrey was able to come the same day, complete an assessment, and define the next steps for the installation of a new hot water heater the following day. He is very personable, professional, knowledgeable and affordable. Yellow Dog is now saved in my iPhone for future project needs! Richard"

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

Install Boiler questions, answered by experts

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.
