Mr & Mrs Smith of NSW changed from storage hot water to the Gleamous GL5 instant hot water in August 2018 and received their May 2019 electricity bill for $453.82. Their previous Electricity bill was $868.29 - that's a huge saving of over $400.00.

They also changed at the same time their quartz downlights (20 quartz globes) to 9 watt LED globes at the same time.

When calculating the cost of hot water system prices, it is not just the initial price of the unit that matters - it is also about the cost of running the unit. Just think about the fact that we use hot water every single day of the year, so it is important to know how much that new hot water system will cost us.


Hot water systems prices don’t reflect the long-term costs that the unit will incur during its lifetime, but Gleamous is so sure that its system will be more cost effective for you, that on this page you can calculate how much the unit will cost you per day, per week, per month and per year.
