I tried using a dehumidifier to save money on energy bills — here's what happened

When Kevin McCloud said a cheap air conditioning trick was to mop a floor, I was intrigued. 

The logic is to do with evaporative cooling, a natural process that also happens to be how air conditioning works. What happens is that as the liquid water evaporates into a gas, it uses heat in the air as an energy source. As a result, the heat loss causes the air to cool.

Amy spent over a decade in London editing and writing for The Daily Telegraph, MailOnline, and Metro.co.uk before moving to East Anglia where she began renovating a period property in rural Suffolk. During this time she also did some TV work at ITV Anglia and CBS as well as freelancing for Yahoo, AOL, ESPN and The Mirror. When the pandemic hit she switched to full-time building work on her renovation and spent nearly two years focusing solely on that. She's taken a hands-on DIY approach to the project, knocking down walls, restoring oak beams and laying slabs with the help of family members to save costs. She has largely focused on using natural materials, such as limestone, oak and sisal carpet, to put character back into the property that was largely removed during the eighties. The project has extended into the garden too, with the cottage's exterior completely re-landscaped with a digger and a new driveway added. She has dealt with de-listing a property as well as handling land disputes and conveyancing administration.
