Microwave is only 60% efficent in using energy relative to what energy goes in and the microwaves that come out. Typically is is operating at about half the efficiency in my kitchen relative to boiling water in a kettle. The kettle wins out.
What is the most energy efficient way to heat water?
A modern combi-boiler, which provides instant hot water, is generally considered to be more energy efficient than a ‘stored’ hot water system. You could install solar water heating (SWH), also known as solar hot water (SHW).
Is electric kettle better than microwave?

Does a microwave use a lot of electricity?

Is it cheaper to boil water in a microwave or kettle?
Microwave ovens at the other hand usually have a 60-65% power efficiency just for microwave generation. So if both electrical appliances have a same power, the kettle will be faster and cheaper in energy. Kettles and also cheaper, but microwave ovens can be used for more things that just boiling water.
Is it cheaper to keep hot water on all the time?
It is a myth that leaving your hot water on all of the time will save you money. Unless you need a constant supply of warm water, your boiler will be constantly heating when there is no real need. It is cheaper and more energy-efficient to switch your boiler on, only when you need the hot water.
Is it cheaper to heat water with gas or electric?
Gas is much cheaper than electricity if you are using it to heat the same amount of water. But some immersion heaters only heat water at the top part of the tank, so if that ‘sometimes only once a week’ demand for water is just for a small amount, the immersion heater could still be cheaper to run!
What’s wrong with microwaving water?
Microwaves make things hot. Microwave ovens shoot tiny waves into the liquid at random locations, causing the water molecules at those points to vibrate rapidly. If the water isn’t heated for long enough, the result is isolated pockets of very hot or boiling water amid a larger body of water that’s cooler.
How much does it cost to heat water with electricity?
Electric hot water on the standard day tariff is hugely expensive, at around $970 a year, or $9700 over 10 years. Off-peak electric hot water is cheaper, but still costs around $460 a year or $4600 over 10 years.
