Best Hot Water Dispenser Buying Guide & FAQ
What Is an Instant Hot Water Dispenser?
Hot water dispensers are essentially small electric elements inside a tank through which water passes or is stored. They need an electricity supply to operate and are designed to rapidly heat larger volumes of water. The main advantage is that the water is instantly available when you need it. They require little power and the energy is not wasted in heating water that is not needed.
These dispensers are typically used to provide hot water for making hot beverages or baby food.
Things to Consider When Choosing a Hot Water Dispenser
You will need to consider if you want a portable or a fixed model. If you simply want instant hot water from a faucet in your kitchen, the fixed model is best for you. If you want a reservoir of hot water, for example in a meeting room in an office, a portable model would be best.
Models also differ by the size of the reservoir and the power of the element. The more powerful the element, the quicker the water will heat up. You may like additional features such as thermostatic controls, burnout prevention, dispenser-locking and LCD display. The taste of the water is important if you are making coffee and tea. For this reason, you may want to choose a model that has a water filter or that has a lining in the reservoir that improves the taste of the water.
There are a number of additional features that some manufacturers offer. Loo out for child safety locks which are essential in a family home. You may also like a timer feature that switches on a heater up to six hours in the future.
Types of Hot Water Machines
There are two basic types of hot water dispensers. Some have a reservoir and heat up a body of water to a temperature around boiling. It is maintained at this temperature so that you can draw it off whenever you wish to. You have to manually top-up the reservoir of these dispensers however, they are often insulated and keep the water hot even when the machine is switched off.
The second type of machine sits under your sink and is linked into your cold water supply. It takes in cold water and passes it over a heated element. These never have to be topped up but they are attached to a fixed faucet so they cannot be moved around. They require an extra faucet at your sink or you may be able to fix them to an existing faucet.
Hot Water Dispenser vs Electric Kettle
A kettle is another way of obtaining hot water but is has some disadvantages. An electric kettle has to be refilled when you use it and a lot of the water that you heat is not used. This is wasteful and uses up power that is then wasted. With a water dispenser, you only heat the water that you need.
Hot water dispensers can heat up larger quantities of water than a traditional kettle. Also, as the name suggests, the water is available instantly! You do not have to wait for a kettle to boil which can be frustrating.
Best Hot Water Dispenser FAQ:
Q: Are hot water dispensers dangerous?
A: Obviously, there is a degree of risk associated with all hot water and that applies to water heated in a pan, in a kettle or in a dispenser. However, many devices have safety locks on the faucets to provide protection. You do have to be careful to keep children away from the hot water just as you would with a kettle.
There is also a danger of microbial growth as the warm temperatures can provide ideal conditions for multiplication. You can avoid these dangers with regular and thorough cleaning.
Q: How do I install my hot water machine?
A: Hot water machines that come with a reservoir simply need to be put together and plugged in. Then you add water and flick a switch.
The models that fit near your sink and attach to a fixed faucet are more difficult to fit but will come with full instructions. You do not usually need specialist tools or knowledge as they come with connectors that fit into your cold water line. If you are not sure about anything, consult the manufacturer or a plumbing expert. Once the machine is fitted, you connect it to a faucet that is fitted on your sink. You may need to make a hole in the counter to fit this.
Q: Do hot water dispensers use a lot of electricity?
A: Hot water dispensers are designed to use very little electricity and are usually a more cost-effective way of heating water than an electric kettle. They use about the same energy as a light bulb. They also result in little waste as you only heat the water that you actually need to use.
Q: How often should I clean my instant hot water dispenser?
A: Hot water dispensers need to be wiped down occasionally to remove dust and dirt and to prevent a build-up of microbes. However, you may also have to descale them from time to time. The frequency with which you have to do this will depend on how often you use your dispenser and on how hard the water supply is in your neighborhood.
In general, if you live in an area that has a hard water supply, you will need to descale every month or so. You can do this using special descaling solutions or powders but check with your manufacturer to see what they recommend for your particular device.
