An instant hot water tap can make tea, oatmeal, and other kitchen tasks quicker by keeping near-boiling water ready at the sink. The right choice depends on more than faucet style: check whether you’re buying a complete faucet-and-tank system or just a replacement faucet, and make sure the tank fits your under-sink space and faucet type. These five picks include complete kits from InSinkErator and American Standard, plus one faucet-only option.

Our Picks: Best Instant Hot Water Tap For Kitchen Sink reviews
1. InSinkErator H-HOT150SN-SS: Best Complete Satin Nickel System
This InSinkErator kit includes a satin nickel dispenser faucet and a 2/3-gallon stainless steel tank, so it’s a complete system rather than a faucet that requires a separate tank purchase. The tank is rated to deliver up to 60 cups of water per hour at 200°F, making it suited to frequent hot-drink preparation and small kitchen tasks.
The faucet has a 6.25-inch spout height and 5.38-inch reach. Those dimensions are worth checking against your sink and counter layout, especially if you have a tall backsplash or limited room around the faucet hole. The tank’s temperature control is adjustable, and the listed tool-free tank connections and dry-start protection are useful installation and protection details.
Compared with the American Standard options, this model has a larger stated tank capacity but a lower stated hourly output. Its satin nickel finish also offers a coordinated look for kitchens where chrome is not the preferred choice. You’ll still need an appropriate power outlet and enough space beneath the sink for the tank.
Pros:
- Includes both faucet and tank
- Stainless steel 2/3-gallon tank
- Adjustable temperature control
- Tool-free tank connections and dry-start protection
Cons:
- Requires under-sink space and an electrical connection
- Spout dimensions may not suit every sink layout
Verdict: Choose the H-HOT150SN-SS if you want a complete system with a satin nickel faucet and a relatively large tank capacity.
2. American Standard Dual-Handle 780W: Best for Temperature Adjustment
This American Standard set pairs a brushed nickel, dual-handle faucet with a 2.5-quart stainless steel tank. Its manual dial lets you select a temperature from 140°F up to 200°F, giving you more control than a system described only by its maximum temperature.
The 780-watt heating element is designed for fast recovery, and the unit is rated to dispense more than 60 cups of near-boiling water per hour. The faucet uses an open-vent design, which is an important compatibility requirement: the manufacturer specifies that it must be used with an open-vent faucet, and using another faucet type will void the warranty.
Its smaller stated tank capacity may be a trade-off for shoppers comparing it with InSinkErator’s 2/3-gallon tanks. On the other hand, temperature adjustment and the dual-handle layout may appeal if you want a clear, manual way to control dispensing and heat settings. Confirm the faucet style and tank dimensions work with your installation before buying.
Pros:
- Includes a faucet and stainless steel tank
- Manual temperature selection from 140°F to 200°F
- Rated for more than 60 cups per hour
- Self-resetting thermal fuse helps protect against accidental dry startup
Cons:
- Requires an open-vent faucet; other faucet types can void the warranty
- 2.5-quart tank is smaller than the 2/3-gallon tanks in the InSinkErator kits
Verdict: This is a strong fit if adjustable temperature and a dual-handle faucet matter more to you than having the largest listed tank.
3. InSinkErator Invite Contour: Best Classic Chrome Kit
The Invite Contour is a complete faucet-and-tank system with a chrome side faucet and a 2/3-gallon stainless steel tank. Its twist-top handle operates the hot water dispenser, while the tank’s temperature control is adjustable. It’s designed to supply near-boiling water at the sink for drinks, cooking, and cleanup tasks.
The product description calls out a single counter hole for installation, along with the need for electricity under the sink. It also lists plastic as the housing material, so shoppers who prioritize a metal faucet body should compare construction details carefully. The description does not give an hourly output figure or exact temperature range, so those are points to verify if they are central to your decision.
Compared with the H-HOT150SN-SS, this model has a similar stated tank capacity and also includes the tank, but it has a chrome finish and twist-top handle. It may suit you if you prefer that traditional control style and want an all-in-one kit rather than sourcing a compatible tank separately.
Pros:
- Complete faucet-and-tank system
- 2/3-gallon stainless steel tank
- Adjustable temperature control
- Chrome faucet with a twist-top handle
Cons:
- Requires an electrical connection and a suitable counter opening
- Product details do not specify hourly output or a temperature range
Verdict: Pick the Invite Contour if you want a complete InSinkErator kit with a chrome finish and a twist-style handle.
4. InSinkErator F-H3300SN: Best Modern Faucet for a Compatible Tank
Unlike the other picks in this guide, the F-H3300SN is a faucet, not a complete instant hot water system. It is designed for use with the InSinkErator HWT-F1000S hot water tank and filtration system, which is sold separately. That distinction matters: buying this faucet alone will not provide the under-sink tank needed to heat and dispense water.
The faucet has a modern satin nickel finish, a swivel spout, and a single-handle design. Its hot lever automatically shuts off, while the cool-water lever stays on. The faucet is made of solid brass, and the listed required hole diameter is 1 3/8 to 1 1/2 inches.
It may be a sensible replacement or style choice if you already have the specified compatible tank system. It is less suitable if you are starting from scratch and want a single purchase that includes the tank. The supplied product information lists this faucet as unavailable, so check its current availability before planning an installation.
Pros:
- Solid brass construction with a satin nickel finish
- Swivel spout for flexible placement
- Hot lever automatically shuts off
- Designed for use with an InSinkErator tank and filtration system
Cons:
- Tank and filtration system are sold separately
- Must be matched with the specified compatible system
Verdict: Consider this faucet only if you have, or plan to buy, the compatible InSinkErator tank system and have confirmed the faucet is available.
5. American Standard ASH-210 1300W: Best for Faster Tank Recovery
The ASH-210 is a complete American Standard dispenser set with a brushed nickel, dual-handle faucet and a 2.5-quart stainless steel tank. Like the other American Standard model here, it offers a manual temperature setting from 140°F to 200°F and is rated to dispense more than 60 cups of near-boiling water per hour.
The main stated difference from the 780-watt American Standard model is its 1300-watt heating element. The product information describes this element as allowing fast recovery, which may be useful when you draw hot water often. Both models use an open-vent faucet design, so make sure you follow the manufacturer’s faucet requirement rather than pairing the tank with an incompatible tap.
The ASH-210 also includes a self-resetting thermal fuse intended to help protect the tank from accidental dry startup. The 2.5-quart capacity is smaller than the 2/3-gallon tanks included with the InSinkErator kits, so compare capacity as well as wattage when deciding which system better fits your routine.
Pros:
- Includes faucet and stainless steel tank
- 1300-watt heating element is described as supporting fast recovery
- Adjustable temperature from 140°F to 200°F
- Self-resetting thermal fuse helps protect against accidental dry startup
Cons:
- Requires an open-vent faucet; another faucet type can void the warranty
- 2.5-quart tank is smaller than the InSinkErator kits’ 2/3-gallon tanks
Verdict: Choose the ASH-210 if you want an American Standard complete kit and value its higher-wattage heating element for recovery between uses.
How to Choose an Instant Hot Water Tap for Your Kitchen Sink
Decide Whether You Need a Complete Kit or a Faucet
Some products include both the faucet and the under-sink tank; others provide only the faucet. A complete kit is usually the more direct choice if you do not already own a compatible tank. If you are replacing a faucet, check the tank model it is designed to work with. The InSinkErator F-H3300SN, for example, is specified for the HWT-F1000S tank and filtration system, sold separately.
Check Faucet and Tank Compatibility
Do not assume that a faucet and tank from different systems will work together. The American Standard models in this guide require an open-vent faucet, and their product information warns that using another faucet type will void the warranty. Confirm the manufacturer’s compatibility requirements before ordering replacement parts or combining components.
Compare Tank Capacity and Output
Tank capacity and hourly output describe different things. The InSinkErator kits listed here have 2/3-gallon tanks, while the American Standard models have 2.5-quart tanks. The H-HOT150SN-SS is rated for up to 60 cups per hour at 200°F, and the American Standard models are rated for more than 60 cups per hour. Consider both measurements if several people may use the dispenser close together.
Look at Temperature Controls
Temperature range can help you decide how closely you want to control the water heat. The American Standard models specify a manual range from 140°F to 200°F. The InSinkErator products listed here describe adjustable temperature control, but their supplied product details do not provide the same exact range. If a particular setting matters to you, check the product specifications before buying.
Measure Your Sink and Under-Sink Space
Check the counter opening, faucet height and reach, and available cabinet space before selecting a model. The H-HOT150SN-SS lists a 6.25-inch spout height and 5.38-inch reach, while the F-H3300SN specifies a required hole diameter of 1 3/8 to 1 1/2 inches. Also make sure you have a suitable electrical connection under the sink.
Consider Installation and Safety Details
Tank connections, dry-start protection, and thermal fuses are practical details to compare. The H-HOT150SN-SS lists tool-free tank connections and dry-start protection. The American Standard models include a self-resetting thermal fuse to help prevent tank burnout if the unit is started dry. Follow the installation instructions for your chosen model, especially when connecting the faucet and tank.
Frequently Asked Questions
Does an instant hot water tap come with a tank?
It depends on the model. The H-HOT150SN-SS, Invite Contour, and both American Standard models in this guide include a tank. The InSinkErator F-H3300SN is a faucet only, and its compatible tank and filtration system are sold separately.
How hot does the water get?
The H-HOT150SN-SS is described as delivering water at 200°F. The American Standard models have a manual adjustment range from 140°F to 200°F. The other InSinkErator models in this guide list adjustable temperature control without specifying an exact range in the supplied details.
Can I use any faucet with an American Standard tank?
No. American Standard specifies that its dispensers are designed to work with open-vent faucets. Its product information warns that using another type of faucet will void the warranty. Check the instructions and compatibility requirements for the exact model you choose.
Is the InSinkErator F-H3300SN a complete hot water system?
No. It is a faucet designed for the InSinkErator HWT-F1000S hot water tank and filtration system, which are sold separately. If you need a full setup, choose a kit that includes a tank or confirm that you are buying all compatible components.
Do these systems need electricity?
Yes. The under-sink tank heats and stores the water, so it needs an electrical connection. Check the specific model’s installation instructions and make sure your under-sink setup can accommodate the tank and power connection.
Which model has the largest stated tank?
The InSinkErator H-HOT150SN-SS and Invite Contour include 2/3-gallon tanks. The American Standard models have 2.5-quart tanks. Compare tank capacity with the listed output and your expected use rather than relying on capacity alone.
Final Recommendation
For a complete system with a larger stated tank capacity, the InSinkErator H-HOT150SN-SS is the most balanced pick in this group. Choose the American Standard ASH-210 if you prefer its adjustable temperature range and higher-wattage heating element, or the 780-watt model if you want the same style of dual-handle system with a lower-wattage element. The F-H3300SN is best treated as a compatible replacement faucet, not a complete kit. Before you buy, verify the faucet type, tank compatibility, counter opening, and under-sink space for your kitchen.
