Install Boiler questions, answered by experts

HVAC systems last between 10 and 30 years, with an average life span of 20 years. However, the components of an HVAC system have different life expectancies. For example, a heat pump lasts between 10 and 20 years on average, while a furnace might last between 15 and 30 years.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The average house radiator has a life span of around 10 to 15 years. However, if you keep up with maintenance, such as bleeding the radiator once per year and removing any signs of rust as needed, your radiator may last 15 to 20 years. Consider hiring a pro to inspect your radiators annually to keep them in the best condition possible.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.
