What’s the Difference Between an Oil Furnace & a Boiler?, West Haven, Connecticut

When it comes to heating your home, the type of equipment you use will make a big difference. However, many don’t fully understand the differences between common systems, such as oil furnaces and boilers. Below is a brief guide to each and what sets them apart, so you can choose what’s right for your house and situation.

Oil Furnace

As the name implies, the unit uses heating oil to warm a home. The fuel heats coils within the furnace, then a blower forces air across them and delivers this hot air throughout the house via a duct ventilation system. Warm air emerges out of the dedicated vents in each room.

A boiler system uses water instead of air to warm a house. However, it still depends on heating oil or another fuel source to generate heat. Once the water is hot, the unit uses a radiant heating system via radiators and baseboard heaters to provide warmth and carry it throughout the house. 

Though boilers take longer to heat up, they are generally more energy efficient and require less maintenance than a furnace. They also add humidity to the air, which can be useful during dry winter conditions.
