- Appliance electricity and water consumption calculator -

Increase your home efficiency, reduce your carbon footprint and save money

The first step towards reducing our energy and water consumption is to increase our knowledge and awareness.

And there is not better way to increase our awareness than calculating how much water and electricity we are using. For that, we have made available several calculators for energy and water calculations.

Before going ahead, we really recommend to first have a look to the Effiworkx YouTube channel videos. On those videos we explain concepts that will be of your interest.

Appliance electricity and water consumption calculators

1 - Appliance power consumption calculator

This calculator can be used to:

Calculate an appliance power consumption. E.g. kettle, microwave oven, toaster…

Calculate an appliance power consumption while in standby mode. E.g. desktop printer, computer monitor, charger,…

Note that an appliance power consumption in standby mode it is most probably much lower than during normal operation. Therefore, in order to calculate the standby mode power consumption of an appliance over time, it is necessary to find out the instantaneous power consumption while in standby mode.

 

2 - Dishwasher electricity and water cost calculator

This calculator can be used to:

Calculate the total cost to run a dishwasher cycle, including water and electricity consumption.

A dishwasher has many different cycles and options to chose from (e.g 70°, 45°, Auto, Rinse, Vario Speed…) and each cycle will have a different electricity and water consumption.

The most effective way to calculate a specific cycle electricity consumption is to use a plug in power meter.

For calculating a cycle water power consumption, the dishwasher manufacturer datasheet can give an indication or we can check the water meter reading before and after the cycle.

 

3 - Washing machine electricity and water cost calculator

This calculator can be used to:

Calculate the total cost to run a washing machine cycle, including water and electricity consumption.

A washing machine has many different cycles and options to chose from (e.g. Regular, Cotton, Delicate,…) and each cycle will have a different electricity and water consumption.

The most effective way to calculate a specific cycle electricity consumption is to use a plug in power meter.

For calculating a cycle water power consumption, the washing machine manufacturer datasheet can give an indication or we can check the water meter reading before and after the cycle.

 

4 - Tumble dryer electricity cost calculator

This calculator can be used to:

Calculate the cost to run a tumble dryer cycle.

A tumble dryer has many different cycles and options to chose from (e.g. Regular, Cotton, Delicate,…) and each cycle will have a different electricity consumption.

The most effective way to calculate a specific cycle electricity consumption is to use a plug in power meter.

 

5 - Buying and appliance: electricity cost and break even point calculator

Buying the most energy efficient appliance is going to save electricity and reduce the electricity bill over time but, if the initial investment it is large, it may take many years to reach the break even point.

As an example, if the average life expectancy of a fridge it is 15 years, is it really worth to purchase a more efficient but also more expensive fridge or would make more sense to buy a less efficient but also less expensive fridge?

Fridge efficieny classA+++A++
Power consumption per year174 KWh/year252 KWh/year
Fridge cost1159899
Electricity cost per year at 0,17 euro per kWh29,5842,84
Electricity cost over 20 years 591,6856,8
Total cost over 20 years (fridge+ electricity)1750,61755,8

This calculator can be used to:

– Calculate the electricity costs over time and the break even point.
