average boiler installation price flat
1 Installing a standard boiler (80%-85% annual fuel utilization efficiency) typically costs about $2,500-$5,000 for a gas-fired model and $3,000-$6,500 for an oil-fired unit (generally used in areas without municipal gas lines).nlike a furnace that heats and distributes air, a boiler heats and distributes water, sending it through pipes as steam to radiators, or as hot water to baseboard heaters, radiant floor systems, snowmelt systems, pool heaters or to a fan coil unit that then heats air. Boilers are typically fueled by gas or oil.
