Things to Consider When Buying an Instant Hot Water Dispenser

Best Instant Hot Water Dispensers

  • Price

The price of instant hot water dispensers can depend on a wide variety of elements ranging from the brand who makes it, the capacity of it, extra features, materials used, and more. There are instant hot water dispensers for under $100 and the price can go up from there.

Things That Affect the Price of a Hot Water Dispenser

Brand – The brand of the instant hot water dispenser is important because a company that specializes in only hot water dispensers may have a more fine tuned product, whereas a large home goods company may offer better customer service. Different brands may also use patented technology that is unique to that manufacturer. The style of the product can also be influenced by the brand that makes it.

Additionally, many modern brands are adjusting to fit the needs of the modern consumer with a focus on sustainability and efficiency. Those with the ecosystem and ethical consumption in mind may prefer to shop with a brand that works with the EPA and Energy Sense to provide eco-friendly and efficient home goods and products. The brands included in this guide have decades of experience in producing home goods and are some of the industry leaders in terms of engineering.

Materials – The materials used in the construction of the instant hot water dispenser will also determine how much it costs. Heavy duty materials are typically more expensive, but there are also many hot water dispensers made out of more lightweight and less expensive metals and manufacturing materials. For a metal finish, the finish itself may also affect the price. A shiny chrome, copper, or gold finish will be more expensive than say something like steel.

The tank of the hot water system is usually made out of stainless steel or another heavy-duty metal. The cost of this metal will vary depending on the thickness and size of the tank. Stainless steel is the best choice for the material of the tank because it is extremely long-lasting, durable, and resilient to heat and moisture. For the spout and faucet of the hot water dispenser there are a variety of different finishes available, but a brass construction is preferable as brass is one of the most durable materials for sinks and will not corrode or rust.

Capacity – Most instant water heaters hold between half a gallon and two gallons of water a time, providing between sixty and one hundred glasses of boiling hot water per hour. The more hot water provided, the more electricity used and the materials needed for the construction of the tank, so a high-capacity water heater will cost more money than a smaller one. The amount of cups of hot water provided is how you can measure the efficiency of the tank. If you need to be able to use lots of hot water per hour, then you will need to invest more money into a high capacity unit.

  • Size and Power of the Tank

Best Instant Hot Water Dispensers The size and power of the tank will determine how much hot water the instant water dispenser can heat and provide at one time. The heating element within the water heater can vary from anywhere between 500 and 1,300 watts and usually hold about a half gallon of water at a time. The power of the tank will also determine the capacity of heat for the water. A large water tank will take more power to heat it to a high temperature efficiently.

Almost all instant water heaters will allow you to customize the temperature via a dial or other control. The size and power of the tank determines how much hot water is being held at one time. Most of the water heaters included in this list can provide sixty cups of water per hour, which is a cup of boiling water per second. A more powerful tank can cost more energy over time, which is why it is also important to consider the energy unit of whichever system you choose.

  • Weight

The weight of the product depends on the materials used and sized. Brass and stainless steel are both heavy duty metals that can carry some weight when they are at a thick gauge. The weight of the system will have an effect on your shipping costs if the shipping costs aren’t included by the manufacturer with the purchase. A heavier product may also be more difficult for you to install yourself and require some help from a professional with installation. The type of metal used and the size of the tank will have the biggest effect on the overall weight of the instant hot water dispenser system.

  • Tank Capacity

The tank capacity refers to how much water the tank will hold at one time. Most of the products in this list can hold less than a gallon of hot water at once and cap out at sixty cups of water per hour at 200 degrees fahrenheit. The tank capacity will determine how much hot water you can dispense per hour as well as affecting the size and energy use of the unit. If you plan on constantly using the hot water heater for teas, coffees, cleaning, and tasks throughout the day you should invest in a high-capacity tank system. If you only want the hot water dispenser for the occasional cup of tea and do not plan on using it more than sixty times an hour, you may as well stick to a lower capacity unit to make the most of your money.

  • Tank Material

The materials of the tank can vary, but should always be made out of a heavy duty metal that is resistant to heat and moisture. The tank material is very important for safety reasons as hot water can be a hazard, even at less than boiling temperatures. Stainless steel is one of the most popular materials for the tank body material because it is resistant to heat, damage, cracks, temperature changes, and moisture. You can depend on stainless steel constructions to last a lifetime without rusting or corroding. The stainless steel should be a thick enough gauge to safely house the water while controlling the temperature. Tanks also include some plastic features. If there are plastic features included this may be a benefit as the price could be less and the product could be less heavy, but be sure that the plastics used are nontoxic and heat resistant.

  • Temperature Range

  • Faucets

Most instant hot water dispensers have a boil dry protection built in to prevent accidents and fires.
