The Pros and Cons of Under-Sink Hot Water Dispensers

Built-in hot water dispensers consist of a small heating tank that you need to install under the kitchen sink and the faucet that can withstand the pressure of boiling water. The tank temperature stays near 200 ° F as long as you keep the unit plugged in and do not change the unit settings. This is much hotter than anything you can get from your regular water heater and is as hot as the water in coffee makers. People install them because of the benefits they offer.

There are a number of benefits to having an under-sink hot water dispenser. First, hot water dispensers under the sink give you what you need instantly so you don’t have to stop in the middle of something and wait for the water to boil. This is a great advantage for those who spend a lot of time working in the kitchen. Next, contrary to the belief that keeping hot water in tanks is inefficient, built-in instant hot water dispensers actually waste less energy than other means of producing boiling water. For example, with a kettle, you often have to heat more water than you need and the unused water ends up getting cold because there is little insulation. On the other hand, under-sink tanks are decently insulated, so there is very little reserve heat loss. Finally, under-sink kettles don’t take up space on your kitchen counter, while kettles or countertop hot water dispensers can be annoying.

With all the convenience they offer, hot water dispensing tanks can also cause some problems if you aren’t careful with them. For example, some inexpensive units can be prone to leaks due to the immense pressure and corrosive effects of constantly boiling water inside. If they fail when you are away from home, there may be serious damage to your property. To avoid these types of accidents, you would do well to drain and unplug any boiling water dispenser in your home if you plan to be away for more than a day. A more dangerous problem with these devices is the risk of burns. Liquids at 140 ° F can cause full thickness injuries in a few seconds and what comes out of an instant hot water tap is much hotter than that. Anyone who puts a hand under that faucet will be seriously injured and this is especially a problem for people who cannot fully understand the risks. If you want to use these systems in homes with older people or young children, you must lower the temperature of the unit to reduce the risk.

In conclusion, hot water dispensers under the sink are useful devices, but you must make sure they are suitable for your lifestyle before purchasing one and you must be careful when using them.
