What We Do
Hot Water Dispenser Services
From new installation to troubleshooting an existing unit — we handle all of it.
New Dispenser Installation
We install under-sink hot water dispenser tanks and faucets in kitchens and wet bars. Installation includes connecting to the cold water supply line, installing the tank under the sink, and mounting the dedicated faucet at the sink.
Dispenser Repair
Not heating? Dripping faucet? Tank not holding temperature? We diagnose and repair all common hot water dispenser issues — heating element failures, thermostat problems, faulty faucets, and tank leaks.
Dispenser Replacement
When a unit is beyond repair, we remove the old dispenser and install a new one. We'll recommend a replacement unit that fits your usage needs and budget.
Compatibility Assessment
Not all sinks have the extra hole needed for a dispenser faucet. We assess your existing sink and countertop setup and advise on installation requirements before any work begins.
Commercial Dispenser Installation
Office kitchens, break rooms, restaurants, and hospitality operations rely on instant hot water for efficiency. We install commercial-grade hot water dispensers built for higher volume demand.
Filter System Integration
Many hot water dispensers can be paired with an under-sink water filtration system so you get instant, near-boiling filtered water. We install integrated filtration and dispenser systems together.

Common Questions
Frequently Asked Questions
How hot does a hot water dispenser get?
Most under-sink hot water dispensers deliver water at 190–200°F — just below boiling. This is hot enough for instant tea, instant noodles, blanching vegetables, and sterilizing, but doesn't require a full kettle boil.
How much does installation cost?
Installation cost depends on whether your sink has an existing hole for the dispenser faucet and how accessible the under-sink plumbing is. We provide a full estimate before any work begins.
Can a hot water dispenser replace my electric kettle?
For most everyday uses — tea, instant coffee, instant oatmeal, cooking prep — yes. The convenience of on-demand near-boiling water at the tap is significant. For full rolling boil (like sterilizing canning jars), you'd still use a kettle or stovetop.
How long does a hot water dispenser last?
Well-maintained units typically last 10–15 years. The most common service items are the heating element and the faucet. Annual descaling is recommended in Hawaii due to mineral-rich water.
