Top 5 Best Instant Hot Water Dispenser for Your House

If you are like most homeowners, you rely on hot water for a number of everyday tasks, from taking a shower to washing dishes. That’s why it is important to have a reliable and efficient hot water dispenser installed in your home.

But with so many different models available on the market, it can be tough to decide which one is right for you. In this blog post, we will outline the best instant hot water dispensers for every type of household. So whether you are in need of a small or large unit, read on for our top picks!

How Do Instant Hot Water Dispensers Work?

Instant hot water dispensers work by heating the water as it passes through the faucet. This means that you can get instant hot water without having to wait for a pot of water to heat up on the stove.

The tank of the hot water dispenser is constantly connected to the sink’s cold-water supply. The tank is usually mounted under or on the edge of the sink, depending on the available place.

The hot water tank dispensers will start heating water, keeping it at a near-boiling temperature as soon as it enters the tank itself. Then, when you use some of the water stored inside the tank, the system will begin to replace the lost water with cold water that is quickly heated inside the tank.

Naturally, the tank is equipped with a thermostat that monitors the temperature of the water and, thus, guides the heating element inside it. It is considered the best alternative to hot water supplies and systems as you don’t have to manually fill the tank with water.

Instant Hot Water Dispenser Buying Guide

When looking to buy an instant hot water dispenser, you’ll want to consider the following factors:

Tank Material

The most common material used for instant hot water dispenser tanks is stainless steel. Naturally, it is also the material that lasts the most, especially when compared to the rubber bladder tanks.

It’s true, the tanks made of rubber bladder will usually cost less than the stainless-steel ones, but they are more likely to give out within the first year of purchase – that’s why we recommend having a stainless-steel tank for your instant hot water dispenser.

 The Size and Power of the Tank

Most instant hot water dispensers out there come with a tank that can hold up to 1/3 or ½ gallons of water. In terms of power, it ranges from 500, to 750, and to 1300 watts. For example, a 750-watt and ½-gallon tank will produce around 60 cups of hot water per hour.

Naturally, tanks with more power can even produce up to 100 cups of hot water per hour – when it comes to this, preferences matter the most. If you are usually using a lot of hot water during the day, then you might want to choose a bigger tank or one that can produce more hot water cups in a day.

Faucets – aka Sink-Top Spouts

Most instant hot water dispensers don’t come equipped with a faucet – however, our list of products does contain more than a few dispensers that come with a classy faucet as well.

Again, this depends on your preferences – for example, you might want to have a faucet for cold water and one for hot water.

So, you may have a faucet connected to a water cooler. Thus, you’ll want one more for the instant hot water dispenser.

Ease of installation

This is a very important aspect that you should consider before buying an instant hot water dispenser – some systems are easier to install than others. If you’re not very handy around the house, then you might want to buy one of those instant hot water dispensers that come with an installation kit and are easier to install.

However, if you are handy and have installed a water heater before, then you can go ahead and buy any instant hot water dispenser that catches your eye.

By considering these factors, you can find the instant hot water dispenser that’s perfect for your needs.
