Instant Hot Water Dispenser Buyers' Guide
Just like the water heater that provides hot water to your sink and bath, a hot water dispenser serves as a miniature version of a boiler and provides instant hot water on demand for your kitchen.
Hot water dispensers are handy for heating water for a variety of kitchen tasks and food prep such as making hot drinks, soups, and sauces. You can also use a hot water dispenser for cleaning tasks, de-thawing, warming a baby bottle, or rinsing stains from clothes. The water provided by a hot water tank is not as hot as true boiling water, but is hot enough to use for a lot of the tasks that you would typically have to boil water for. A hot water tank is also faster than heating water in a kettle.
Some instant hot water heaters are made for installation under the sink, whereas others are a separate piece, but both types connect directly to your water supply. Below-sink hot water dispensers are the most practical. Typically their hot water tank is made of stainless steel and includes a metal heating element that uses electricity for heating water to exactly the right temperature.
The temperature of the water provided by a hot water dispenser varies and typically caps off at around 200 degrees. Some hot water dispensers can also provide cold water and can replace a regular sink faucet in a pantry or bar. High-quality hot water dispensers sometimes include safety features to prevent overheating, but in general are very safe for use in the home.
Things to Consider
Many hot water dispenser brands are adjusting to fit the needs of the modern consumer with a focus on sustainability and efficiency. If you prefer to shop ethically, look for 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.
The materials used in the construction of a hot water dispenser will also determine how much it costs. Heavy duty materials are typically more expensive, and the finish can also affect the price. A shiny chrome, copper, or gold finish will be more expensive than like steel.
The hot water tank in an instant water system is usually made out of stainless steel or other heavy-duty metal. For the spout and faucet of the hot water dispenser there are a variety of different finishes available, but brass is preferable as it resists corrosion and has a long life.
Capacity and Power
Most instant hot water heaters hold between half a gallon and two gallons of water a time, providing between sixty and one hundred glasses of near boiling instant hot water per hour. Still, your model's exact capacity and power will determine how much hot water your instant water dispenser can heat and provide at one time. A high-capacity instant hot water tank will use more energy (and cost more money) than a smaller one.
The heating element within the hot water tank can vary from anywhere between 500 and 1300 watts. Bear in mind that a more powerful heater will use more energy over time, which is why it is also important to consider the energy unit of whichever system you choose.
There are a range of temperatures available on almost all instant hot water dispensers. Since they are typically made specifically for kitchen tasks, it is essential to be able to pinpoint the right temperature for proper cooking and cleaning. The temperature range can vary from product to product, but generally starts at between one hundred and one hundred and fifty degrees Fahrenheit and stops a bit of above 200 degrees Fahrenheit, but not letting the water boil.
Often the faucet is included with the purchase of a hot water dispenser, but you can also buy tanks and faucets separately. Be warned that sometimes using the wrong faucet with the hot water tank could void the warranty.
Some faucets have the option of either hot water only or both hot and cold water, so you can use the faucet as your main water source, including cool water for a bar or pantry. The finish for the faucet can vary, but brass is usually the best material for the main construction of the faucet as it is resilient to all kinds of damage including rust and corrosion from water and heat.
Boil Dry Protection
If the hot water tank is empty and the unit attempts to boil it, this can be a safety hazard. Most instant hot water dispensers have a boil dry protection built in to prevent accidents and fires, and this is a good safety feature to check for when you're shopping.
Water from an instant hot water heater can cause accidental burns and scalds to sensitive skin. Choosing a dispenser with a built-in safety lock is one way to prevent accidental burns. This is especially important if you live in a home with children or elderly who may accidentally turn on the wrong faucet to wash their hands and burn themselves.
Most instant hot water dispensers are very energy efficient and cost as little as six cents a day. When shopping for an instant water dispenser, look for Energy Star approval to check that your unit will be as efficient as possible. Energy Star products are rated 20% more efficient than others, which protects the environment and also reduces your energy bill.
The thermostat on a hot water dispenser system should be adjustable and go up to a temperature that is nearly boiling and hot enough to make tea, coffee, soup, and other dishes. The range of temperatures can vary, usually capping off at around 200 degrees which is perfect for cleaning and hot drinks. Sometimes the thermostat will display the hot water tank temperature digitally, or it may indicate the temperature via an LED light on the tank.
Modern instant hot water dispensers come in a variety of styles and colors. If you do not want a traditional boring looking water faucet, there are a lot of interesting colors available like gold or black that can spice up your kitchen and will add to your decor. Popular colors for dispensers include metallic chrome, brushed nickel, copper, bronze, oil rubbed bronze, and stainless steel
Installing an Instant Hot Water Dispenser
Installation processes can vary for instant hot water dispensers, and if you decide to hire a professional installer you'll need to take the cost of labor into consideration. If you are hiring, it's always a good idea to use a brand approved installer, as sometimes DIY installation can void the warranty on the product. Customer service websites can usually help with this.
There can also be safety concerns with installation due to electricity and water, which is why leaving installation up to a professional plumber is recommended though not required.
