Electric Patio Heaters – Do They Use a Lot of Electricity?

Keeping electricity costs low is a prime concern, and many of us find ourselves evaluating the electricity usage of the heating systems we have in place.

This doesn’t stop in the summer!

Patio heaters are a popular choice from late spring through to early autumn, to make the most of the longer evenings.

But do electric patio heaters use a lot of electricity, and are they worth it?


Gas or Electric Patio Heater?

Gas patio heaters are extremely popular, yet they are not the most economical choice based on the cost of replacing gas canisters.

Due to the fluctuation of electricity costs, it can be tricky to determine exactly how much an electric patio heater will cost to run.

However, if you are keen to keep electricity usage costs and carbon dioxide emissions down, it’s clear that Electric Patio Heaters are the best choice over gas heaters.

At ATC we have analysed the cost of using gas versus electric outdoor heaters over an annual period, and the savings per week are immense!
