Avalon Cold & Hot Water Dispenser – Top Loading

14 new from $175.79
1 used from $147.51
Free shipping
Amazon.com
as of September 15, 2022 12:49 am

PROS:

  • A larger quantity of hot water
  • Easy to maintain
  • Time saving & energy efficient
  • Child safety lock

CONS:

  • Temperature is not adjustable

The Avalon is a standard top loading dispenser with an excellent hot water function. This is a heavy-duty model at 35.5 lbs and 14.5 x 14.3 x 46.5 inches. All of the dispensers we’ve mentioned so far have been mainly for residential use, however, the Avalon is suited for both residential and commercial purposes. It’s ideal for offices and clinics where both hot and cold water may be required.

The unit is top loading and saves time because a single 5-gallon bottle can be loaded once and lasts for several days. Even though the temperature is not adjustable, it is consistent. You will always get 185° F hot water which is suitable for tea and coffee and the cold water option provides water at 47° F. If there are kids around then the hot water can easily be locked.

It is a misconception that bigger units take more energy and time to heat or cool water. In this case, the dispenser is energy efficient, only using 450 watts to heat the water. This makes the Avalon one of the more energy efficient hot water dispensers on this list. It is also a low maintenance unit as the drip tray is removable.

Types of Hot Water Dispensers

Just by going through the list above, you’ll notice that there are several types of hot water dispensers, each with its own pros and cons.

Let’s begin this buying guide by taking a look at the types of hot water dispensers on the market and what they offer.

Here are five main types.  

1- Hot Water Tank Dispenser

These devices are connected to the water supply, with the hot water dispensed from a faucet. Tank dispensers are typically installed under the sink or on the counter, next to the faucet. Some units have in-built water filters and most come with a thermostat that allows you to adjust the water temperature. Because these devices don’t require manual filling, they supply water on demand as required.

Pros:

  • Don’t require manual filling
  • On-demand hot water supply
  • Works like a regular tap
  • Can be installed out of sight
  • Supply large amounts of hot water

Cons:

  • Require some plumbing and installation
  • Not portable
  • Typically expensive
  • They keep water hot at all times which is not highly energy-efficient

2- Countertop Hot Water Dispenser

Countertop hot water dispensers are smaller units which can be placed on the counter or dining table and used as required. These units are portable making them versatile machines, but they’re typically smaller in capacity. Countertop hot water dispensers are perfect for smaller households with lower hot water needs.

Pros:

  • Portable and easy to move around
  • Ideal for smaller households
  • Not very expensive
  • Don’t require plumbing

Cons:

  • Small capacity
  • Requires manual filling

3- Thermo Pot Hot Water Dispenser

These devices work somewhat like a kettle and a flask. They can be compared to tank storage water heaters in that they heat up the water and then keep it at a steady temperature until used. Thermo pots are ideal for outdoor use, for example when camping. They’re also suited for smaller households with lower hot water needs.

Pros:

  • Don’t require installation
  • Reasonably priced
  • Portable devices
  • Some units have adjustable temperatures

Cons:

  • They need to be refilled
  • They aren’t highly energy efficient

4- Top Load Hot Water Dispenser

Top load hot water dispensers are quite common in commercial spaces, especially offices and waiting rooms. These typically come with hot and cold water options, with some including a third option – room temperature water. These units typically have large capacities, up to 5 gallons or more which means they only need to be refilled every few days. However, they’re generally not suited for residential purposes.

Pros:

  • Large capacity
  • Ideal for commercial spaces
  • Hot and cold water options

Cons:

  • Typically costly
  • Requires special refilling bottles
  • Heavy to deal with – bottles need to be lifted and placed upside down

5- Bottom Load Hot Water Dispenser

These are the opposite of the top load dispenser, in that the bottle of water is placed at the bottom of the dispenser, typically out of sight. This makes it easier to change bottles, as they don’t require lifting and placing upside down. These are also typically used in commercial spaces.

Pros:

  • Convenient to use
  • Modern designs
  • Best for commercial purposes
  • Large capacity

Cons:

  • Typically expensive
  • Ongoing cost of replacement bottles

Hot Water Dispenser vs. Kettle

Let’s begin by addressing the elephant in the room. You might be wondering why you need a hot water dispenser if you have a kettle at home. After all, don’t kettles do the same thing?

Yes and no. Kettles have their benefits as inexpensive devices that give you hot water in several minutes. However, there are some benefits that hot water dispensers have over them:

  • Hot water dispensers work at a faster rate, typically giving you hot water instantly. You don’t have to plug them in and wait around till they boil
  • Kettles have smaller capacities compared to hot water dispensers with the average model typically offering around 1 to 1.5 liters of hot water at a time. Depending on the model, hot water dispensers can give you hot water at up to 100 cups per hour.
  • On the flip side, kettles also don’t let you boil small quantities of water. If you have a need for very little hot water, you’ll still have to boil a considerable quantity in your kettle. A dispenser allows you to use just as much as you need at a time.
  • You don’t have to lift up and carry the hot water dispenser as you would a kettle. This makes it a more convenient option for those with grip issues and the elderly.
  • Kettles don’t allow you to adjust the temperature. Hot water dispensers typically have a thermostat that lets you adjust the temperature as per your requirements.
  • Kettles work well for smaller households or low hot water needs, while hot water dispensers can be used in both residential and commercial spaces.

How to Buy a Hot Water Dispenser

When buying a hot water dispenser, there are many factors to consider to help you choose the right model and capacity for your needs.

Here are some factors to consider:

  • Where will you be using the hot water dispenser? This is probably the first question to ask. You might be looking for a dispenser for your home, office, waiting room or gym to name a few. The type of device you choose will depend on where you use this.
  • How much hot water do you require daily? In other words, what is your hot water usage and what do you use the hot water for? Answering these questions will make it easier to decide on the type and capacity. If you use a lot of hot water daily, you will require a device with larger capacity or one that works on demand.
  • What type of hot water dispenser works best for your needs? As we’ve seen, there are several varieties of these machines, each with their own pros and cons. You’ll find that having a fixed system will give you hot water instantly as and when you require it whereas portable systems are more versatile but also more manual. Weigh the pros and cons to zero in on the best type.
  • Consider the price. Again, the type of hot water dispenser will impact the price. Some units are more expensive upfront with costs for installation, but once installed they work for years with minimal maintenance, whereas others may be cheaper to purchase but may have shorter durability.
  • Consider durability and quality of construction. Check how well the device has been constructed, what materials have been used and how long the warranty is for. Some machines are made of stainless steel with metal finishes, but they can be prone to rust and corrosion, whereas models made of plastic may look good but have shorter lifespans.
  • Do you want both cold and hot water? If you want both hot and cold water, your options may be narrower and you may need to go for a top or bottom load hot water dispenser.
  • Consider the size of the unit. This depends on where you plan to use the device. As we’ve seen in our reviews above, hot water dispensers vary in size. Some of the largest units are the top and bottom load dispensers, while under-sink and countertop dispensers can be quite compact. The size you choose will depend on the space you have for it as well as the capacity you require.

The Features to Look For

Now that you’ve decided on the above points, let’s quickly go over the main features to look for in a hot water dispenser.

  • Tank

Not all hot water dispensers come with tanks. Models with tanks are usually installed under the sink. It’s important that the size of the tank fits into your under-sink space so ensure that the measurements are correct.

  • Side water gauge

This is typically located on the side of the unit, indicating the amount of water left in the container. Gauges are found on most portable units.

  • Faucet

If the model is a point of use one, it will generally dispense the water via a faucet installed at the sink. Check to see if the faucet comes with the model, to avoid issues of compatibility. Some devices are compatible with standard faucets, which means that you won’t have to purchase a new faucet but can simply connect the dispenser to your existing faucet in the kitchen.

  • Electric power

Consider the amount of electricity the unit uses and how energy efficient it is. Generally, the higher the power usage, the faster the device heats water but the less energy efficient the device is overall. Unless you require a large quantity of hot water at a time, it’s best to opt for a unit that uses less power.

  • Rubber feet

This might seem like a small detail, but it can make the difference between a unit that slips and one that remains steady. It’s an excellent safety feature especially if you have small children around.

  • Indicator

Most units come with indicator lights that tell you at what stage of heating the water is at. Red typically means that the water is being heated towards the maximum temperature while green means that it’s ready to use.

  • Finishes

This is a purely aesthetic consideration and depends on your preferences as well as on the décor of your kitchen. Most hot water dispensers have metal finishes, but some can have stylish black or white finishes. Again, this isn’t a critical feature.

  • Thermostat

Most units will come with a thermostat that allows you to adjust the temperature as per your needs. However, some types of dispensers, like the top load or bottom load models, come with fixed temperatures.

  • Water Flow Per Hour

Most models will indicate how much water flow the unit is capable of producing per hour at a certain temperature. As we’ve noted in the reviews above, this can range from 30 to 100 cups. This is an important consideration as it’s directly related to your hot water usage.

  • Filtration

Some units come with a filtration system to ensure that the device doesn’t get blocked or clogged up with dirt and debris. This feature is especially useful if you live in a hard water zone, where sediment and residue is a common issue. A filtration system ensures that any contaminants in the water has been reduced or removed, so you know that the hot water comes clean and free of contaminants. However, note that filtration systems require replacement and more maintenance. Additionally, you might be interested in a more comprehensive filtration system, by choosing a filter for your whole house, instead of just for the hot water dispenser.

  • Locking lid

This is a safety feature that comes with some models. It ensures that your device can be locked to avoid inadvertent spills or splashes. Locking lids are mainly found on countertop or Thermal pot style hot water dispensers.

Frequently Asked Questions – FAQs

1- Are hot water dispensers better than kettles?

In general, hot water dispensers are better than kettles because they tend to be more economical, especially if you use a lot of hot water. They tend to be faster and they supply large amounts of hot water. They also have wider applications, as they suit a variety of spaces, including offices, gyms, waiting rooms and other commercial spaces.

2- What are the functions of a hot water dispenser?

Hot water dispenses have many functions. These can include:
1- Instant hot water whenever you need it.
2- Use for making hot beverages like hot chocolate, herbal teas, tea or coffee.
3- Melts wax, removes stains on clothes and linen and can be used to soak your dishes when washing.
4- Heat up baby formula if required.
5- Make large quantities of coffee or tea at a time.
6- Use for instant foods like powder soup, instant noodles or oatmeal.

3- How do I descale a hot water dispenser?

A: This would depend on the model. Some come with self-cleaning features, where all you have to do is press the button and the system descales itself. However, in general, follow the instructions that come with the user manual.
Don’t use harsh chemicals to clean the unit as this can be damaging. The most widely used, efficient and safe method to clean mineral buildup is to use a vinegar rinse.

4- Is an instant hot water dispenser safe to have in the kitchen?

If you follow the instructions of installation and use, yes, it’s a safe and handy device to have in your home. Some models come with extra safety features, including rubber pads for the feet, locking features, auto shut off and so on.

 The Bottom Line

A hot water dispenser is a convenient device to have in your home or office. The right unit can produce as much hot water as you require, when you require it.

These devices are easy to use and typically less bulky. With so many options on the market, there’s a model for every space and requirement.  

When installed correctly as per the manufacturer’s instructions, hot water dispensers are safe units that can be used for years to come with minimal maintenance.
