Having a well humidified home is a wonderful feeling in the dead of winter when everything is cold and the air is dry. There is a lot of discomfort associated with dry air that can be avoided by simply setting up a humidifying system in your home.

Despite the fact that humidifiers run off electrical power, they can actually be responsible for helping you to lower your energy usage during the winter. Whole house humidifiers are especially effective and can assist you in lowering your power bills by as much as 5% a year!


There are two main types of humidifiers: single room units and whole house humidifiers. Many people use a single room humidifier while they sleep to help ease the discomfort of dry air. However, if you want to get the most benefit from a humidifying system including the full energy savings, for example, you want to work all day in your garage in winter because you have installed an electric garage heater, then you should invest in a system that will humidify your entire home.

A whole house humidifier usually connects directly to your ventilation system and your furnace. When the furnace turns on so does the humidifier. As hot air blows past the humidifier system, whichever type of system you choose to get, the air will pick up the moisture and blow out humid air rather than dry air.


So, how does humid air help to save you money on your energy bill? Here are a few reasons why:

  1. They only operate when the furnace is running

Rather than running continuously, these systems turn on and off when the furnace does making their time very efficient and well-planned. You won’t be paying for too much as you don’t have to keep the system running 24/7 in order to keep your air pleasantly humid.

  1. Control of the unit is automatic and based on a humidistat

Most units are attached to a humidistat and programmed to operate around the readings given by the device. If your home is humid enough already, your humidifier will not turn on. If it needs humidity, the unit will turn on and function normally. Not only does this prevent you from having to run the unit all the time, it also helps to keep your relative humidity levels in the right range to avoid mold while helping you stay comfortable.

  1. Your home feels warmer when the air is humid

Humid air feels warmer than dry air. By adjusting the humidity levels up you may be able to turn your furnace down by a few degrees or more. A reduced energy bill from lower heat levels makes a gigantic impact on your annual power bill. The best part is that you won’t even notice the difference in heat levels and may even feel more comfortable than you did before!

It’s estimated that by increasing your relative humidity by 30% – a fairly normal amount during the winter, as the air is far too dry for comfort – you will feel as many as 3 degrees warmer at the same temperature. That means if you set your thermostat to 70, you may be able to lower it to 67 without being noticeably colder.
