Selecting a good instant hot water dispenser may, however, be somewhat confusing because there are tons of options available in the market from different brands.
These are the best when it comes to quality, performance, and design as you are going to see in our in-depth reviews. We’ll also provide you with the ultimate buying guide plus other important information about instant hot water dispensers to help you make the right purchase decision.
Let’s get started.
What is an instant hot water dispenser?
An instant hot water dispenser is a system or device that’s designed to provide hot water on demand through a special auxiliary faucet installed near the sink. These appliances are able to heat water to temperatures of about 201oF or close to the boiling point.
How does it work?
An instant hot water dispenser operates much like an electric water heater or electric kettle. The system is made up of a faucet and the main unit that contains an electric heating element and a small storage tank.
The main unit is connected to the cold water supply line under the sink and then to the hot water faucet it comes with which is installed onto the sink separate from your regular faucet.
The cold water from the supply line flows through the body of the faucet and then it’s diverted into the heater tank where it’s heated up to a near-boiling temperature by an electric coil (the heating element) and held in the tank waiting to be dispensed through the faucet for use.
Unlike conventional water heaters, the tank in hot water dispenser systems never becomes pressurized and this is because these dispensers use an open-vent faucet which basically means that there’s no valve on the faucet gooseneck.
For a conventional water heater system, the faucet valve is usually placed right after the heater tank which results in a pressurized tank. However, in an instant hot water dispenser system, the faucet valve sits right before the tank hence resulting in an “open-vent” style faucet.
With this design, the pressure never builds up inside the heater tank which is very important as too much pressure inside the tank would consequently result in failure.
So, how does an instant hot water dispenser gets to deliver the hot water to your faucet?
Well, once the water is heated by the electric coil, it expands and fills the expansion chamber within the upper part of the storage tank.
When you open the faucet, more cold water flows into the bottom part of the tank, thereby displacing the hot water held in the tank and the expansion chamber. As a result of this displacement, the heated water is forced out of the tank and up through the faucet for use.
The hot water arrives immediately and is much hotter compared to the standard hot water taps. You don’t wait at all for it to warm up although the spout dispenses the water slowly compared to a typical faucet.
Most instant hot water dispensers come with an adjustable thermostat which controls the water temperature. This way, the system is able to maintain the water temperature according to how you set the thermostat. The thermostat also turns off the heating element once the water in the tank attains the set temperature.
Some more advanced units feature a control dial that allows you to adjust the thermostat to tweak the temperature and even turn the unit off.
Adjustment is often required only when water is too cool or so hot such it boils away and causes the tank to overheat.
What are the benefits?
Having an instant hot dispenser installed in your kitchen has several benefits which include:
Hot Water on Demand
The primary benefit you stand to get from having an instant hot water dispenser is a ready supply of hot water whenever you need it whether it’s for basic household use such as drinking, preparing beverages, food, etc, or any other application.
If you have a very busy lifestyle and often don’t have the time to wait for the water to boil on the stove or coffee maker to heat up, then you really need to invest in an instant hot water dispenser.
You will enjoy the benefit and convenience of having hot water instantly straight from the tap saving you a lot of time.
Water heaters can boil water too but the downside is that you will have to wait until the water boils in the kettle. However, with an instant hot water dispenser, you get the hot water right away allowing you to enjoy your hot beverage or prepare your food in no time.
Constant Supply of Hot Water
Another reason why you may need an instant hot water dispenser is the fact that it can give you hot water constantly. With a kettle or any other conventional water heater system, you can only heat a limited amount of water.
An instant hot water dispenser, on the other hand, always comes with a storage tank and the capacity of this tank is quite a benefit as it can fill at least several gallons of water.
This means that whenever you draw hot water through the faucet, you’ll likely never have to wait until the tank is refilled again to heat more water.
The tank fills itself continuously since whenever you open the faucet to get hot water, cool water from the supply flows into the tank to displace the heated water and force it through the faucet. Therefore, it’s able to produce hot water constantly, and for the entire day.
Furthermore, with an instant hot water dispenser, you can easily heat a larger amount of water continuously without any issues unlike water heaters or a kettle which limits you to a certain amount.
An instant hot water dispenser features a heating element that uses energy to heat the water. The good thing though is that, unlike other water heaters, instant hot water dispensers are usually built to be energy efficient.
As such, they tend to use much less energy than ordinary kettles or water heaters to deliver hot water. The heating element (electric coil) is thermostatically controlled hence it only maintains a certain temperature according to your thermostatic settings.
Moreover, it’s not constantly heating like a home water heater since the thermostat turns off the system once the water in the storage tank reaches the set temperature.
Basically, these dispensers use around 0.5 to 1 kWh of electricity in a day, therefore, the cost of running one based on our rough estimate would not be more than 10 cents a day.
However, the cost of power varies from one place to another, so equally the operating cost may vary depending on the area you live in.
Adjustable Water Temperature
The availability of a thermostat and a control dial (switch) in instant hot dispensers allows you as the user to control the temperature of your water.
This is a beneficial feature you won’t get with an ordinary water heater or kettle since it allows you to adjust the heat in order to keep the water at a temperature that you desire or prefer.
Unlike a kettle, instant hot water dispensers are versatile appliances that you can use for a number of things like preparing beverages in the morning, making food like pasta or macaroni, warming baby bottles, and cleaning kitchen counters or other surfaces with a cloth dipped in warm water.
In other words, an instant hot water dispenser provides a wonderful way of tackling multiple kitchen-centric tasks using just one appliance.
Compact and Hassle-Free Operation
The last benefit of these dispensers lay in their ease of use and feasibility. While they come in a wide range of designs and designs, they are really easy to use even for persons with disabilities.
First, the control dial or switch gives you easy control over the system allowing you to adjust the water temperature to your liking as well as turn the dispenser on/off with ease.
Second, these units have a sleek look that makes them presentable and they are quite compact hence can fit in any kitchen design no matter the size.
