One thing you’ll love about the Waste King H711-U-SN is its sleek design. It will add elegance and convenience to your kitchen. The hot water dispenser kit includes an elegantly satin nickel curved Coronado faucet and an insulated stainless steel 1300-watt hot water tank.

The InSinkErator, H-HOT100S-SS, on the other hand, includes a 750-watt, 2/3 gallon stainless steel hot water tank and a modern chrome finish hot water faucet.

2. Size

H711-U-SN tank has a height of 11.2 inches, 6.8 inches width, and a depth of 8.1 inches. Its compact size makes it easy to install under your kitchen sink without free space issues. The dispenser is also lightweight at 13.21 pounds.

H-HOT100C-ss is actually smaller than the Waste King model as it measures 5.38 x 2.00 x 6.24 inches. It is also lighter with a weight of 7.4 pounds. It takes very little countertop space to set up hence perfect for kitchens with small countertops.

3. Performance

At 1300 watts, you can get 100 cups of water per hour when using H711-U-SN. The unit allows you to choose a temperature range of 140 degrees F to 190 degrees F.

The dispenser’s faucet can produce at least 60 cups in an hour hence highly efficient. With this unit, you are assured of minimal spillage now that the tank is completely enclosed. Heating is done in a stainless steel 5/8 gallon tank, which is fully insulated.

This performance makes this hot water dispenser a good backup tank or additional tank.

With a power rating of 750 watts, the InSinkErator H-HOT100C-SS raises the water temperature to your level of choice in 12 to 15 minutes. It’s equipped with an adjustable thermostat that enables you to set the heat value within the range of 160 degrees F to 210 degrees F.

The dispenser comes pre-set at 200 degrees F, which you can use as a default and then adjust with time. With this range, you can use this unit to prepare tea, gourmet coffee, steam vegetables, warm baby food, among other applications.

Heating is done in a 2.5 (2/3 gallons) liter stainless steel tank that is rust-free, tough, and durable.

4. Safety Features

H711-U-SN includes a safety feature that allows a decrease and increase in temperature without risking the expansion of the bladder. This might, however, cause the faucet to drip because of the open-vented safety system.

Thankfully, the unit’s expansion chamber is self-contained and reduces dripping. You can also lower the occasional dripping by lowering the temperature using the setting knob.

On the other hand, the InSinkErator features dry-start protection, which prevents the dispenser from heating up when the tank is empty. This dry-start protection also ensures easy set up and peace of mind.

5. Ease of Use

Both models are extremely easy to use. After installation, you just need to operate the faucet on the countertop. These faucets come with an integrated hot lever that fits perfectly in your hand for easy use.

The lever of these units comes with a convenient self-closing valve that shuts off automatically for safe use. This helps to prevent accidental burns and wastage.

6. Installation

Before you start setting up H711-U-SN, keep in mind that the unit should be installed vertically. You can install the faucet in a spray hose in your sink’s opening or drill a hole for it. Ensure that the diameter of the hole is 1 ¼ inches minimum and 1 3/8 inches maximum.

Waste King H711-U-SN comes pre-installed with a power cord. The package also comes with quick-connect fittings, with and without a filter. The fittings minimize the risk of having the water lines twisted or kinked.

The fittings enable you to get a neater-looking water line, but you have to purchase separate tubings.

The installation process of the H-HOT100C-SS is quite simple since it’s designed as a DIY project with no complicated plumbing required. You can complete all tank connections tool-free, and the dry-start protection makes the process easy.

However, just like with the H711-U-SN, you’ll have to drill a 1.25 to 1.5 inches hole on your countertop/sink for mounting the faucet. To complete the installation process, you’ll also need compression fittings, a dedicated control valve, and T-fittings.

Detailed installation and troubleshooting instructions are provided and explained step-by-step in the user manual for easier guidance.

7. Cleaning and Maintenance

The 2 products are extremely easy to clean and maintain since only the faucet is exposed, and cleaning is usually done in this section. You, therefore, have very few parts to clean. All you need is a mild detergent and a soft sponge to get the work done.

You also need to clean the unit’s tank every once in a while, especially if you notice discolorations or rust in the water. Clean it also if the dispenser has not been in use for some time.

To do this, unplug the dispenser, then push the faucet level, and leave the water to flow until it’s cool. After that, shut off the water supply, undo the tubing and then unhook the tank from the wall.

Lift the tank upside down above the sink and drain out all the water. When this is done, install and hook up the plumbing.
