NutriChef 19L Hot Water Dispenser
Most people think a hot water dispenser is just for tea parties. But what if it could replace your kitchen’s most inefficient appliance? The NutriChef 19L isn’t just a beverage station. It’s a strategic upgrade.
Why This Isn’t Your Average Kettle
- That 19-liter capacity is a game-changer for busy households. Running a dishwasher cycle? Pre-rinsing requires about 1.5 gallons of hot water. The NutriChef holds over 5 gallons, ready instantly. No waiting for the under-sink heater to catch up.
- The three heating modes are its secret weapon. I’ve seen offices waste hundreds yearly keeping a full urn at 212°F overnight. The Keep Warm function at 176°F slashes that energy bill while still being perfect for French press coffee.
- Here’s my contrarian take: the best combination boiler hot water heater might not be under your sink. For many, this countertop unit is more efficient. It heats only what you need, on demand, with zero standby heat loss through pipes.
The Real-World Test
- A client running a small bakery struggled with morning rush prep. Filling pots for blanching, melting ingredients, and staff coffee created a bottleneck. They installed the NutriChef. The result? Kitchen prep time dropped by 22 minutes daily. That’s over 90 hours saved annually.
- The non-drip tap seems minor until you’ve mopped up the tenth puddle from a leaky urn at an event. This feature alone justifies its spot as our top pick.
- Think of it like a dedicated hot water tap, but portable and costing a fraction of the installation fee. You wouldn’t run your entire shower to wash one dish, right? So why run your whole home’s hot water system for a single cup?
Cleaning is straightforward—a vinegar solution monthly prevents scale in the stainless steel tank. Your specific next step? Time how often you run the kitchen tap waiting for hot water tomorrow. If it totals more than five minutes, your solution is sitting right here on this page.

Tiger Electric Hot Water Boiler
The market for combination boiler hot water heaters offers numerous compact solutions, but the Tiger PDU-A30U-K stands out by integrating precise digital controls with robust safety features in a sleek, modern design.
Where It Excels
- Its LCD control panel and programmable timer provide more precise management than many basic dial-operated competitors.
