Before buying a water boiler and warmer, take into consideration capacity, temperatures, and energy-saving features. To help you with this, we’ve put together this handy buying guide!
Water boilers and warmers come in a variety of sizes that hold varying amounts of water. For a small number of drinkers who aren’t constantly after hot water, a boiler with a capacity of around three liters will probably be sufficient.
If the boiler has to serve more people or will be used very frequently, then we would recommend a water boiler that is over four liters. Five liters is generally the largest size available and this should be considered for large families or office use.
As water boilers serve the purpose of ensuring you always have hot water available, buying a boiler that is too small would not be very useful! Instead of having hot water when you need it, you will have to keep refilling it and waiting for it to boil again.
However, if you buy a boiler that is larger than you need, you may find it takes up too much space in your kitchen. It also won’t be energy efficient, as you will be wasting electricity heating more water than you need.
Water boilers serve to boil water and keep it warm, of course, but they can heat water to different temperatures.
If you’re only looking to get hot water to make that perfect cup of coffee or tea, then a boiler that can produce variable temperatures may not be necessary. The optimal temperature for brewing both is around 185 degrees Fahrenheit (85 degrees Celsius.)
However, if you’re looking to make instant ramen with your water boiler, then boiling temperatures of around 212 degrees Fahrenheit (100 Celsius) are best. The more uses you’ll have for your water boiler, the more temperature settings you will need!
As water boilers and warmers have hot water on tap, the potential for injury can be very high. That’s why it’s important to make sure that any boiler you buy is safe.
If the boiler is going to be used in a place that is accessible to children, then make sure it has a child-safety lock. These can take many forms but are generally an extra button or two that needs to be pressed before the hot water is dispensed, making it less likely that small hands will get the right combination.
Something else to look for is an auto-shutoff feature that will stop the warmer from continuing to heat when the water level is either too low or empty. Make sure that the unit has a lid that locks securely. This will not only prevent spills but can also stop children from opening the boiler and putting their hands inside.
Many boilers have electrical cords that don't plug into the unit but are instead magnetic. This ensures that if the cord is pulled, instead of potentially knocking over the boiler, it will just disconnect.
One final feature to check for is vacuum insulation. The heat should stay inside the boiler and not heat the exterior, as this will increase the risk of accidents.
Boiling water requires electricity—this will be the case for all water boilers and warmers, of course! However, not all boilers need to be continually using electricity. Some water boilers also act like a Thermos, and once the water is boiled they will be able to keep it hot for several hours without the need for any electricity.
If you do want to save energy and switch your boiler off after it's reached temperature, then keep in mind that many only dispense the hot water when they're turned on. If you observe Shabbat each week, then one with a manual dispenser is a must.
Water boilers generally come in one of two materials: metal or plastic. Both of these have their advantages and disadvantages. Plastic is lighter and more portable than metal. It won’t rust, although any metal heating elements inside will if not cleaned and maintained correctly.
Metal boilers can be either stainless steel or aluminum. They’re more durable than plastic and usually come with more temperature options than plastic boilers. As metal conducts heat more efficiently than plastic, it's important that they are well-insulated.
No matter what material the outside of your water boiler is made from, the heating element inside will be made of metal. As many of us know, metal is prone to rust and corrosion. This is especially the case when boiling water.
Some higher-end water boilers have a self-cleaning function that will descale the inside of the water boiler, breaking down any mineral deposits and prolonging the life of your boiler. If you don’t buy a boiler that has this feature, make sure that you regularly clean and descale it yourself.
You can also prolong the life of your water boiler by using distilled water instead of tap water. Some manufacturers actually recommend this.
