"This has been a big project. Removing old oil fired boiler which provided heat and domestic hot water. Installed duct in attic, furnace, heat pump, hot water tank. Upgraded electric service. The entire crew has been neat, organized, professional and the quality of workmanship has been great. I would recommend Elmarair to anyone in need of HVAC service or install."

Install Boiler FAQs, answered by experts

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

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.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

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

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
