    How to Save on Your Bathroom Energy Bill



February 2018


Bathroom energy saving tips for modern homes

Over the last decade or so, bathroom technology has evolved tremendously. Gone are the days of bath, basin, and toilet! Modern bathrooms contain incredible gadgets that turn the average wet room into a sanctuary. Heated towel rails, underfloor heating, steam showers with in-shower entertainment, and automatic toilets are some of the inventions that have become commonplace in bathrooms around the world. And with that, comes a new source of energy bills.

So if you’d like to save money on your bill, the bathroom is a great place to start.

How to save money on your energy bill

We love our electric toothbrushes, shavers, hair straighteners, heat lamps and illuminated mirrors. They enhance our experience and enhance our comfort and productivity. But they can also add to our energy bills. It’s crucial to know the hidden costs associated with all these appliances before you purchase. Luckily, there are ways to save energy without compromising on convenience.

Install an energy efficient hot water heater

When it comes to saving money, it’s smart to start with the biggest energy users. The hot water heater is often the biggest electricity user in the bathroom and in the home. Mineral deposits build up inside the tank, causing it to have to work harder to deliver the same result. That uses extra electricity. If your hot water heater is less than 8 years old, call your plumber to flush it out. If it’s older than 8-10 years, it’s probably time to replace it with a new energy efficient hot water heater.

If possible, consider moving your hot water system nearer to the taps you use most often. Ask your plumber to install a heat trap near the hot water outlet. Also insulate the first two metres of pipe that lead out of the system.

Tankless water heaters offer the new standard in energy efficient hot water heater installations. Or your could opt for a recirculating pump system.

Turn on to an energy-efficient shower

Few things are as relaxing as a long, luxurious bubble bath, but a shower is much more economical. Invest in a low-flow energy-efficient shower head (capped at 2.0-2.5 gpm) to help you save up to 19 litres of water per minute. 1

Turn the water off while you lather your body, brush your teeth, or shave and only use water to rinse yourself off. To save water limit your showers to four minutes. If you allow the hot water to run, you’re also wasting the electricity that was used to heat that water.

Turn on the timers

Time management is an important factor in saving energy in the bathroom. Hook all your electrical bathroom appliances up to a timer, including the hot water heater, underfloor heating, and heated towel rails. In summer, turn off the underfloor heating and heated towel rails.

Lighten the load

Reduce your electricity use by replacing your existing lighting with compact fluorescent lamps. CFL bulbs may be up to 80% more energy efficient 2, but they provide the same light as incandescent bulbs.

Fix any leaks fast

Did you know that a dripping hot water tap can waste enough water in one day to allow one more person to take a shower? Fix leaking taps by replacing the washers and seals.

Simplify and don’t standby

Speaking of toothbrushes and razors that require charging: avoid them! Seriously, these devices are convenient to use, but you’re less likely to put them away when you’re done using them. That means that you may end up leaving them on charge.

Devices using standby electricity can add up to 10% of your electricity bill. 3 Rather ditch the appliances and use manual equivalents. You’ll probably save money and frustration. How often have you wanted to use a device, just to find the battery is empty? When it comes to investing in an energy efficient shower or energy efficient hot water heater, look out for Energy Star certification.

The final word

Bathrooms are a common high energy-usage area in your house, but, by incorporating the above mentioned tips on energy-efficiency, you can have a modern bathroom at a fraction of the energy cost. This is not just good for your wallet, but for the environment too, as these small changes can make a big impact on your greenhouse gas emissions and energy consumption.
