    Hot water dispensers allow you to instantly make hot drinks, soups, oatmeal, and more. Some hot water dispensers can produce cold water as well as hot. Theoretically, you could use a product like this as your only kitchen faucet.

    What Can I Do With a Hot Water Dispenser?

    If you're still wondering whether you really need a hot water dispenser, consider a few of the things you can do with these handy kitchen helpers.

    • You can quickly make hot drinks, such as tea and coffee.

    • You can fill pots with near-boiling water to cook pasta or rice faster.

    • You can get instant hot water for foods like packet soup and oatmeal.

    • You can warm baby bottles quickly and easily.

    • You can produce very hot water for soaking dishes with stuck-on food.

    • You can remove stains from clothing and kitchen linens.

    CAUTION

    Be careful of letting small children around your hot water dispenser – it might be wise to get a child lock for it.

    Hot Water Dispenser vs. Kettle

    You might be wondering why you'd choose a hot water dispenser over a kettle. Let's look at some of the areas where a hot water dispenser is superior to a kettle.

    • Hot water dispensers are instant, so you can save yourself a lot of time.

    • They're great in offices where people would otherwise have to boil water in a kettle over their break or lunchtime.

    If you want to fit your hot water dispenser in an existing sink and you have a water sprayer you don't mind losing, you could remove it and put the new faucet in its place.

    • Hot water dispensers are great for elderly people and those with reduced grip strength, as the risk of dropping a full kettle (and suffering a burn) is decreased.

    • Kettles usually won't let you boil less than a pint of water at a time. If you require only a small amount of hot water — for a single cup of tea, for instance — a hot water dispenser can be more energy-efficient.

    • Some hot water dispensers allow you to adjust the water temperature, which makes them more versatile than kettles.

    EXPERT TIP

    The risk of scalding from hot water dispensers is very low, so they're perfect for elderly people, disabled people, or anyone who has trouble gripping objects.

    Considerations

    Considerations

    Tank Size

    The tank of a hot water dispenser goes beneath your sink, where it's connected to the cold water supply. When choosing a hot water dispenser, it’s important to look at the external dimensions of the tank portion, as you must have enough space for it in your undersink area.

    As for the internal capacity, the majority of tanks hold somewhere between one-half and two-thirds of a gallon. A tank with a larger capacity can heat more water in an hour. Unless you want to make more than 60 cups of coffee in an hour, however, a tank with a standard internal capacity is all you need.

    DID YOU KNOW?

    A hot water dispenser has two main parts: the tank, which is fitted under the sink, and the faucet, which sits alongside your other kitchen taps.

    Considerations

    Wattage

    A watt is a unit of power, so the higher the wattage, the more powerful the hot water dispenser.

    A hot water dispenser with higher wattage will usually heat water faster and in larger amounts.

    Considerations

    Faucet

    The hot water is dispensed from a faucet.

    But unless you already have the right type of faucet installed on your sink, you may need to buy one separately.

    EXPERT TIP

    Hot water dispensers have a special kind of faucet that stops water pressure from building up in the tank. Not all hot water dispensers come with a faucet; some are sold as a tank only. If you buy your faucet separately, make sure it's the right kind — a regular tap will not work.

    Considerations

    Finish

    Presumably, you'll want the finish on the faucet of your hot water dispenser to match your other taps and kitchen hardware.

    Most hot water dispensers only have faucets that come in chrome, which is a drawback if you have a different finish on your other taps. However, you can find faucets in finishes other than chrome if you do a bit of digging.

    If you want your hot water to come out as close to boiling as possible, consider a model that can heat water up to 200°F.

    Considerations

    Heat Settings

    Hot water dispensers offer a variety of heat settings. There's usually a dial on the outside of the tank that lets you adjust the heat.

    The exact temperature of each setting varies with different models.

    Considerations

    Cups Per Hour

    You can look at a product’s wattage to ascertain its power, but it's also useful to know what that means in real terms.

    If you read the product descriptions or manufacturer specifications, most will tell you how many cups of hot water the unit can dispense in an hour.

    DID YOU KNOW?

    Most hot water dispensers can put out between 60 and 100 cups of water (190°F - 200°F) in an hour.

    Considerations

    Filtration System

    Some hot water dispensers also come with filtration systems.

    The water comes out of your tap pre-filtered, which is handy if you're concerned about the quality of your tap water or if you live in a hard water area.

    EXPERT TIP

    Unless you have some plumbing experience, we recommend getting a professional to install your hot water dispenser.

    Price

    Lower-end hot water dispensers start at around $125 to $150. The most expensive units on the market can cost upwards of $600.

    With the most expensive options, you're often paying more for a trusted brand name. A decent mid-range option of $200 to $300 is usually just as long-lasting. But while the cheaper models (under $200) work just fine in the short term, they may break down after only two or three years of use.

    If you spend four minutes a day waiting for a kettle to boil, that works out to roughly 24 hours a year.

    FAQ

    Q. Are hot water dispensers safe?

    A. For the most part, yes, hot water dispensers are perfectly safe. That said, there is a risk that young children could scald themselves. If you can't keep your kids away from the sink — and they're too young to understand not to touch — look for a model with a child lock on the faucet.

    Q. How do I install my hot water dispenser?

    A. Installing a hot water dispenser isn't exactly straightforward. Unless you're particularly handy, we advise calling a plumber.

    The tank needs to be positioned under the sink so it can be connected to your main water supply. It also needs to either be plugged into a power outlet or hardwired into your electrical system. You also need to have a hole in your sink to fit the faucet — or you need to make a hole if there isn't one.

    Q. Can my hot water dispenser be installed at any time?

    A. Because you require a hole in your sink for the faucet to come through, most people install a hot water dispenser when refitting their kitchen. It is possible to fit a hot water dispenser with an existing sink, but you'll need to get a professional to make a hole for the faucet. And if you have a porcelain sink, you risk cracking it.
