Swamp coolers need a constant supply of water. As water keeps evaporating from the unit to cool the air, more water needs to replace it. Most water use estimates range from 3 to 15 gallons / 11 to 57 litres per hour, with averages between 7 and 11 gallons / 26.5 and 40 litres.

Beside this, How much does it cost to run a swamp cooler all day?

Swamp coolers will cost about $2 to run for 24 hours. To run a unit 24 hours a day, every day, for an entire month, it would cost roughly $60. In comparison, a central AC costs about $330 per month at this rate.

How do evaporative coolers work best?

At what humidity do evaporative coolers become ineffective?

The higher the humidity, the less effective evaporation will be as a cooling method. For example, while the air is at 10% humidity, the swamp cooler can drop temperatures by up to 20 to 30 degrees, while at 50% humidity, the swamp cooler can drop temperatures by about 10 degrees.

How much humidity is too much for a swamp cooler?

humidity. The swamp cooler is working harder to get the 75 degrees and you may be up to 80 – 85% relative humidity. You probably don’t want to get the humidity much above 55%.

Do Evaporative coolers use a lot of electricity?

Evaporative coolers cost about one-half as much to install as central air conditioners and use about one-quarter as much energy. However, they require more frequent maintenance than refrigerated air conditioners and they’re suitable only for areas with low humidity.
