## What does a pool aerator do?

An aerator is an attachment that plugs orscrewsinto the side of your pool that sprays a fountain ofwaterbeing back into your pool.

## How many gallons is my pool?

Length x width x depth x 7.5 = volume(ingallons)
Length times width gives the surface area ofthepool. Multiplying that by the depth gives the volumeincubic feet. Since there are 7.5 gallons in each cubicfoot,multiply the cubic feet of the pool by 7.5 to arrive atthevolume of the pool, expressedingallons.

## What is a reverse cycle heat pump?

Conventional heaters have to 'create' heatenergy,while a reverse cycle heat pump 'absorbs'heat fromthe outdoor air to warm the air inside, which is amore energyefficient technique. This refrigerant is then pumpedthrough acompressor into a fan coil unit inside the home,releasingheat into the room.
