The Easter long weekend is only surpassed by the Christmas and new year period as a time when families travel to be together. It is also the start of the hot water season when clients are reminded of the ever-increasing hot water electricity cost.
For the plumbers at Whywait Plumbing, Easter is a busy period with blocked drains being the most common problem followed by hot water problems.
Unlike Christmas, there is always a spike over Easter in emergency callouts for faulty hot water units. That is because Easter is generally much cooler than Christmas. Around April, we all suddenly realise that cold weather is on the way. Every year we notice the signs with an increase in emergency service callouts with the problem being no hot water. Even in the relatively mild climate of South-East Queensland no-one willingly wants to have a cold shower.
Frequently we cannot help but shake our head’s at all the stress, the waste of time and money these emergency service calls represent to many homeowners. Sadly many of us do not pay too much attention to the myriad of household and mechanical systems that provide so much comfort and convenience in our modern lives. We take for granted our water heaters, toilets, mixer taps, and air conditioners that is until they stop working. Then come the panicked call and a repair job that always ends up costing more than we expect.
Showers are the activity where we use the most hot water. Generally, 40% of the water consumed in the shower is hot water. This is why there is a strong correlation between the length of a shower and the hot water electricity cost.
If your home is like many in South East Queensland you are producing hot water from an electric hot water service connected to tariff 11 with a shower rose you love because you get a deluge of water from it at 23 litres per minute. If your shower is being utilised four times a day for an average of 5 minutes per shower, then those showers are costing you $1125 a year in electricity costs and $107 in water usage costs.
Essentially 1 kilowatt-hour of electricity is used to produce 15 litres of hot water using an electric element hot water service. With electricity prices expected to increase 21% on 1 July and a further 40% over the next three years, there is considerable scope for reducing your hot water electricity cost.
One option is to change your electricity and water guzzling shower rose to a water efficient shower rose using only 9 litres per minute. Based on the standard example above this would immediately reduce your electricity costs to $440 and water cost to $42. If you are able to change your hot water service from tariff 11 to tariff 33, then you will save an additional 40% on electricity costs.
The best option and the one we recommend is the long-term sustainable option utilising heat pump technology. Heat pump technology involves replacing your old fashioned energy-hungry electric hot water service to the highly efficient Sanden “Eco®” Plus Heat Pump hot water system.
Electricity costs have become a political hot potato, with state and federal governments playing the blame game in blaming each other for the doubling of electricity prices in recent years.
Hot water electricity cost is one area you can reduce your electricity costs substantially by being smart about how you heat your hot water and use it. Hot water generated by electric elements is something we always took for granted. That is until surging electricity price increases made us all take another look at our increasingly energy-intensive lifestyles.
