Installation And Operation Variables For Furnaces And Wall Units

Posted on: 2 December 2021

If an old baseboard heating system in your residence is being replaced with a more modern heating device, you may be contemplating the purchase and installation of a furnace or a wall heater. Each heater type possesses benefits and drawbacks. Learn the variables associated with the installation and operation processes for each heater type.


A gas or electric-powered furnace generates enough heat to warm up an entire home. Old furnaces from decades ago used to be monstrous pieces of equipment that would take up a very large amount of space. They consisted of a large base with thick pipes connected to it. Modern furnaces do not require as much space.

The body and piping that comprises a furnace are streamlined. Many furnace models will fit inside of a basement, an attic, or a closet. During the installation of a furnace, the piping that transfers heated air will need to be attached to ductwork. A furnace will contain a filtering system. 

An HVAC contractor will need to install a thermostat panel that can be used to turn on and off the heating unit. Because a furnace will use a considerable amount of gas or electricity to operate, it may not be the most economical way to heat your home.

Wall Units

Wall units are designed to be recessed into a wall. They do not require any attachments or ductwork. This means that the installation of this type of heater will not take as long as the installation of a furnace. A contractor will need to locate wall studs within the room where a wall unit will be installed.

They will determine an ideal location for the heater to be placed. A section of the wall will need to be cut out prior to securing a unit within the hole that remains. Insulating materials may be installed around the outside of a unit. Most wall units do not require the use of a filter.

Since there will be no ductwork or filter present, dust accumulation will occur much more quickly than if you were to use a furnace to heat your home. An HVAC technician will secure a grated cover over a wall unit. The cover will need to be vacuumed or dusted regularly. A wall unit is designed to heat a small space. This type of heating unit is most suitable for the heating of a single room or apartment.
