At Nellis Air Force Base, several different factors can affect how much you pay for a new boiler and installation. These are: the type of boiler, the size of the installation, and the facility's requirements. When you factor in those variables, on average you're looking at basic installation in the range of $3,000 to $7,000 for a standard residential boiler, and at the upper end of the range, the installations are bit more complicated. If you're looking at a commercial installation, or a high-efficiency boiler, or just a bigger boiler for more space, then you're looking at a simple estimation from $10,000 to $20,000 or more.
