Since boiler and radiator heating systems are typically found in older homes, boiler installation is often a replacement task rather than a task performed during new home construction. Despite the popularity of other heating units in new structures, one thing that no one can deny about boiler and radiator heating systems is that they are extremely durable. Though boiler installation is less common than furnace installation, those who have the former are rarely in any hurry to switch to the latter. Boiler and radiator heating systems are much more expensive to set up than furnace and forced-air systems, but the comfortable, moist heat boiler and radiator systems produce is something many find preferable to the dry heat created by forced-air systems.
