The best InSinkErator hot water dispenser for a setup that already has a compatible tank is the F-GN1100C faucet. For a complete hot-only system, the HOT150 includes a tank and faucet, while the F-HC1100SN adds a cool-water lever but needs its tank and filtration system separately.

For a bottled cooler with a built-in coffee brewer, see our 5 gallon water dispenser with K-Cup guide.

These under-sink systems heat water for a small dedicated faucet beside the main kitchen faucet. Compare under-sink instant hot water dispensers to review more setup options.

The main choice is whether you need a faucet alone or a complete set, and whether you want hot-only or hot-and-cool dispensing.

How we chose these InSinkErator hot water dispensers

We compared the faucet and tank configurations, control styles, temperature details, installation notes and warranty information for each option. Our score weighs specs, features and buyer feedback against what you're shopping for.

A faucet-only model can be a good fit when the compatible tank is already installed. If you need the full setup, prioritize a system that includes both the faucet and tank, then compare finish, handle design and the space available under your sink.

The HOT150 appears in two finishes, so those options are listed separately because the finish may determine which one fits your kitchen. The Ready Hot tank is included as a non-InSinkErator alternative, but it requires a Ready Hot faucet and doesn't complete an InSinkErator setup.

Compare the best InSinkErator hot water dispenser options

The main difference is whether each pick includes a tank and whether it serves hot water alone or hot and cool water. Use the table to narrow down the setup before reading the details.

The best InSinkErator instant hot water dispenser picks

The best choice depends on what is already under your sink and how you want to control the faucet. Start with the first pick if you have a compatible tank, or choose a system below when you need the faucet and tank together.

1

InSinkErator F-GN1100C Contemporary Instant Hot Water Dispenser-Faucet: Best for an existing InSinkErator tank

9.7/10Our score

• Faucet only
• Solid brass construction
• 360-degree swivel spout
• Automatic shutoff when the lever is released

This chrome faucet is for a setup that already has a compatible InSinkErator hot water tank and filtration system. Its spring-closing lever and swivel spout suit a dedicated hot-water tap beside the main faucet.

See it on Amazon

Pros

• Brass construction
• 360-degree swivel spout
• Automatic shutoff

Cons

• Tank and filtration system sold separately

The F-GN1100C is a faucet-only option, so it makes sense when the compatible InSinkErator tank and filtration system are already part of your kitchen. The faucet has a high-arching spout that swivels 360 degrees and a lever that shuts off automatically when released.

Its solid brass construction and chrome finish give it a clean look beside a transitional main faucet. The faucet needs a deck-mounted hole, and the product details specify a maximum counter thickness of 3 inches.

This model is hot only. If you also want a dedicated cool-water lever, compare the F-HC1100SN below, which is also faucet only and requires the HWT-F1000S tank and filtration system.

Choose the F-GN1100C when you want its faucet design and already have the matching tank setup. If you need a tank included, the HOT150 systems are the more direct comparison.

2

InSinkErator H-HOT150SN-SS Instant Hot Water Dispenser System: Best for a satin nickel complete set

9.6/10Our score

• Faucet and 2/3-gallon stainless steel tank
• Delivers up to 60 cups per hour
• Adjustable temperature control
• Tool-free tank connections

The satin nickel HOT150 combines a faucet and tank for buyers who want the system together. It delivers up to 60 cups per hour, with an adjustable control and dry-start protection.

See it on Amazon

Pros

• Faucet and tank included
• Tool-free tank connections
• Dry-start protection

Cons

• Requires an unswitched AC outlet and dedicated water connections

The satin nickel HOT150 is a complete hot-only system with a faucet and 2/3-gallon stainless steel tank. It delivers up to 60 cups per hour, with an adjustable temperature control and tool-free tank connections.

The included tank has dry-start protection, and the faucet has a satin nickel finish. The system requires an unswitched AC outlet, a dedicated control valve with compression fitting, and a T-fitting, so check the under-sink setup before installing.

Pick this finish if it works with the other fixtures in your kitchen. The chrome HOT150 below has the same core tank-and-faucet arrangement.

3

InSinkErator HOT150 Instant Hot Water Dispenser System: Best for a chrome complete set

9.5/10Our score

• Faucet and 2/3-gallon stainless steel tank
• 750-watt tank
• Adjustable temperature control
• Tool-free tank connections

This chrome HOT150 has the same core setup as the satin nickel version, with a faucet and 2/3-gallon tank. Choose it when chrome best matches the main kitchen faucet.

See it on Amazon

Pros

• Faucet and tank included
• Adjustable temperature control
• Dry-start protection

Cons

• Requires an unswitched AC outlet and dedicated water connections

The chrome HOT150 offers the same basic combination of faucet, 2/3-gallon stainless steel tank and adjustable temperature control. Its tank is rated at 750 watts, and the system includes dry-start protection and tool-free connections.

Like the satin nickel version, it needs an unswitched AC outlet and dedicated water connections. The faucet requires a single countertop hole, so measure the available opening and counter thickness before choosing a system.

Choose this version when chrome is the better match for your main faucet. If a twist-top handle appeals more than the HOT150's single handle, the Invite Contour has that control style.

4

InSinkErator Invite Contour Instant Hot Water Dispenser: Best for a twist-top handle

9.4/10Our score

• Chrome faucet and 2/3-gallon stainless steel tank
• Twist-top handle
• Adjustable temperature control
• Hot-only system

The Invite Contour pairs a chrome faucet with a 2/3-gallon tank. Its twist-top handle gives it a different control style from the single-handle HOT150 systems.

See it on Amazon

Pros

• Faucet and tank included
• Twist-top handle
• Temperature control adjusts from 160°F to 200°F

Cons

• Plastic faucet housing

The Invite Contour pairs a chrome faucet with a 2/3-gallon stainless steel tank. Its twist-top handle is the clearest difference from the HOT150, whose faucet uses a single handle.

The system's temperature range is 160°F to 200°F. Its faucet housing is plastic, so consider that material alongside the chrome finish and handle shape when comparing it with the metal HOT150 and HOT250 faucets.

Choose the Contour if the twist-top design suits how you want to operate the tap. The HOT250 is another complete set, with a swivel spout and a pull-forward handle.

5

INSINKERATOR HOT250 Instant Hot Water Dispenser System: Best for a longer service warranty

9.3/10Our score

• Faucet and 2/3-gallon stainless steel tank
• 360-degree swivel spout
• Pull-forward handle
• 3-year limited service warranty

The HOT250 is a satin nickel faucet-and-tank set with a swivel spout and pull-forward handle. InSinkErator backs it with a 3-year limited service warranty.

See it on Amazon

Pros

• Faucet and tank included
• Handle pulls forward to avoid wall interference
• Dry-start protection

Cons

• Requires a standard faucet hole and an under-sink outlet

The HOT250 combines a satin nickel faucet with a 2/3-gallon stainless steel tank. Its spout swivels 360 degrees, and the handle pulls forward to reduce interference with a wall or backsplash.

InSinkErator backs the HOT250 with a 3-year limited service warranty. The faucet needs a standard 1 3/8-inch hole, and the tank needs an under-sink power outlet.

Its handle is spring-loaded to close when released, and the tank has dry-start protection. Choose this model if those details and its longer stated service warranty matter more to you than the simpler HOT150 setup.

6

Ready Hot Stainless Steel Hot Water Dispenser: Best for a larger tank reservoir

9.2/10Our score

• 2.5-quart stainless steel tank
• Adjustable temperature from 140°F to 200°F
• Faucet sold separately
• Tank designed for Ready Hot faucets

This Ready Hot option is a tank only, with a 2.5-quart reservoir and manual temperature dial. It works only with Ready Hot faucets, so it isn't a complete InSinkErator system.

See it on Amazon

Pros

• Larger reservoir than the 2/3-gallon systems here
• Manual temperature dial
• Self-resetting thermal fuse

Cons

• Faucet sold separately
• Designed to work only with Ready Hot faucets

The Ready Hot is a tank-only alternative, not an InSinkErator system. Its 2.5-quart stainless steel reservoir holds more than the 2/3-gallon tanks in the InSinkErator sets here, and its manual dial adjusts temperature from 140°F to 200°F.

The important fit limit is the faucet: this tank is designed to work only with Ready Hot faucets, which are sold separately. It is not a compatible replacement to assume will pair with an InSinkErator faucet.

Choose it only if you're considering the Ready Hot system as a whole. For an InSinkErator faucet-and-tank set, the HOT150, Contour, HOT250 or Wave is a better match.

7

InSinkErator HOT100 Instant Hot Water Dispenser System: Best for push-button activation

8.7/10Our score

• Chrome faucet and 2/3-gallon stainless steel tank
• Easy-push button activation
• Adjustable temperature control
• Tool-free tank connections

The HOT100 pairs a chrome faucet with a 2/3-gallon tank and push-button activation. It suits buyers who want that control style in a complete hot-only system.

See it on Amazon

Pros

• Faucet and tank included
• Push-button activation
• Dry-start protection

Cons

• One-year in-home service warranty

The HOT100 is a chrome faucet-and-tank system with push-button activation. Its 2/3-gallon stainless steel tank has adjustable temperature control, tool-free connections and dry-start protection.

The faucet requires a standard 1 1/4-inch to 1 1/2-inch hole, with a maximum counter thickness of 2 inches. It also needs an unswitched AC outlet and dedicated water connections.

Choose the HOT100 if you prefer push-button activation. The HOT150 is a close alternative with a different faucet handle style and a clearly specified stainless steel tank.

8

InSinkErator Contemporary Instant Hot and Cold Water: Best for hot and cool water at one faucet

8.5/10Our score

• Hot-and-cool faucet only
• Solid brass construction
• Hot lever shuts off when released
• Cool-water lever stays on

This satin nickel faucet provides both hot and cool water, with separate lever behavior for each. It requires the InSinkErator HWT-F1000S hot water tank and filtration system, sold separately.

See it on Amazon

Pros

• Hot and cool from one faucet
• Solid brass construction
• Hot lever automatically shuts off

Cons

• Tank and filtration system sold separately
• More involved installation

The F-HC1100SN is the only hot-and-cool faucet in this group. It has separate levers: the hot lever shuts off when released, while the cool-water lever stays on.

This is a faucet only, intended for use with the InSinkErator HWT-F1000S hot water tank and filtration system, sold separately. The faucet is made of brass and has a satin nickel finish.

Choose it when you want hot and cool water from one dedicated faucet and already have, or plan to add, the required tank and filtration system. For a separate explanation of cold-water dispensers, see [What Is a Cold Water Dispenser?

What Really Happens](/what-is-a-cold-water-dispenser/).

9

InSinkErator H-Wave-SN Involve Wave Instant Hot Water: Best for a lever-activated complete set

8.0/10Our score

• Satin nickel faucet and 2/3-gallon stainless steel tank
• Lever activation
• Adjustable temperature control
• Dry-start protection

The Involve Wave is a complete hot-only system with a satin nickel faucet and tank. Its lever-activated faucet offers a different style from the HOT150's single handle.

See it on Amazon

Pros

• Faucet and tank included
• Lever automatically shuts off when released
• Temperature control adjusts from 160°F to 210°F

Cons

• Requires an unswitched AC outlet and dedicated water connections

The Involve Wave is a complete hot-only system with a satin nickel faucet and 2/3-gallon stainless steel tank. The lever-activated faucet shuts off when released, while the tank has adjustable temperature control and dry-start protection.

The system needs an unswitched AC outlet, a dedicated control valve with compression fitting, and a T-fitting. Its faucet requires a standard 1 1/4-inch to 1 1/2-inch hole, with a maximum counter thickness of 3 inches.

Choose the Wave if its lever style and satin nickel finish suit your kitchen. If tea is your main reason for adding instant hot water, compare our best instant hot water dispenser for tea guide.

Should you choose a faucet-only model or a complete system?

Choose a faucet-only model if you already have the matching InSinkErator tank and filtration system. The F-GN1100C is hot only, while the F-HC1100SN serves hot and cool water.

A complete system makes more sense when you need the faucet and tank together. The HOT150, HOT250, HOT100, Contour and Wave are complete options, each with a 2/3-gallon tank.

Confirm that a faucet-only model matches your existing tank before buying. A separate tank or filtration setup can affect both fit and installation.

Is a hot-and-cold InSinkErator faucet right for you?

Choose the hot-and-cool faucet when one extra sink tap for both functions suits your kitchen. The F-HC1100SN is the only hot-and-cool option in this group, and it requires a separate HWT-F1000S tank and filtration system.

The hot and cool levers work differently: the hot lever closes when released, while the cool lever stays on. The available details call the cool water “cool” and don't specify a chilled temperature.

If you need a system for a workplace or other high-use setting, see our best commercial instant hot water dispenser roundup. Commercial needs may differ from a household faucet-and-tank setup.

What should you check before installing one?

Check the faucet hole, counter thickness, power outlet and water connections before choosing a dispenser. Those requirements vary by model, and several complete systems need an unswitched outlet plus dedicated water fittings.

The F-GN1100C requires a standard 1 1/4-inch to 1 1/2-inch hole and allows up to 3 inches of counter thickness. The HOT250 specifies a standard 1 3/8-inch hole, while the HOT150 requires an unswitched AC outlet and dedicated water connections.

Measure under-sink space for the tank and access to its controls. If the installation conditions are unclear, confirm them with a qualified installer before making a cut in the counter.

Which InSinkErator hot water dispenser should you choose?

Choose the F-GN1100C if you have the compatible tank and want a hot-only brass faucet. Choose the HOT150 if you need a complete set, or the F-HC1100SN if you want both hot and cool water from one faucet.

For an all-in-one hot-only system with a longer stated service warranty, consider the HOT250. If you mainly want hot water for tea, compare the best instant hot water dispenser picks and check that the tank, faucet and installation needs match your kitchen.

Frequently asked questions

Does an InSinkErator hot water faucet include a tank?

Some do, and some are faucet only. The F-GN1100C and F-HC1100SN require compatible tanks and filtration systems sold separately, while the HOT150, HOT250, HOT100, Contour and Wave are system options with tanks.

Check what you already have under the sink before choosing.

Can an InSinkErator hot and cold faucet provide chilled water?

The F-HC1100SN is described as providing hot and cool drinking water. Its cool lever stays on, while the hot lever shuts off when released.

It uses the HWT-F1000S tank and filtration system, sold separately.

The available product details don't specify a chilled water temperature.

What should you check before installing an instant hot water dispenser?

Check for a suitable faucet hole, an under-sink outlet and the water connections the chosen system needs. The HOT150 requires an unswitched AC outlet, a dedicated control valve with compression fitting, and a T-fitting.

Hole size and counter thickness limits vary, so compare those with your sink setup.

What is an instant hot water dispenser used for?

An instant hot water dispenser supplies near-boiling water at the sink for drinks and kitchen tasks. Common uses include tea, coffee, oatmeal, loosening jar lids and steaming vegetables.
