1. Size Of Tub

The size of your tub can be a deciding factor. Keeping the water warm will use more energy. And using more energy will add up to your monthly bills. Before you choose the tub, consider the following things:

  • How Many People Are Going To Use It
  • Drainage And Refilling it

Draining the tub could be a difficult task. So, keep in mind that bigger is not always better.

2. How Often You Use It

While calculating the electricity consumption of a hot tub, the cost-deciding factor is how long you have to use it.

Naturally, using it for prolonged hours will keep on adding to the bill. Many people left their tubs on overnight to attain the perfect temperature. 

Should You Leave Your Hot Tub On All The Time?

Even though they are designed to be left on, it is not an energy-efficient move. 

Hot tubs get hotter very slowly. Leaving them on overnight can consume more than normal electricity. 

Leaving it overnight could cost you an additional £40 per month. So, we strongly suggest you turn it on only a few hours before you’re going to use it.

3. How Hot You Want It

Most of the hot tubs are designed to increase the 2 °C per hour. So, it can take hours before it hits your perfect heat settings. That’s why setting your spa tub at the highest temperature is expensive.

Bigger heating motors use more energy and can consume 6000 watts of electricity per cycle.
