A Reddit question about getting a steady supply of hot water without using tap water turned into a practical discussion of appliance options.
The replies focused on whether a product exists or whether the answer was some mix of filtration, storage, and improved heating.
Here's what to know
"I want constant hot water when needed. … I want a giant thing I can fill with my own filtered water and have hot water always available," the poster wrote.
In response, commenters narrowed the idea down to a few workable paths. One common suggestion was a hot water system installed under the sink and paired with filtered water.
As one commenter said: "You're looking for an Instahot system. There are under-sink models where you add a tap on your sink, and there are countertop versions."
Other users recommended electric hot water pots, insulated carafes, and water coolers that dispense hot water.
The first route uses a filtered line, while the other avoids a sink-fed setup.
More background
Several commenters took "tap water" to mean unfiltered sink water, not a desire to stop using the home's regular water supply.

The right pick depends on what the person actually wants. For filtered water kept near boiling or ready for tea, a countertop boiler or dispenser may be the simplest fit. For a more seamless built-in option, an under-sink hot-water system with filtration is probably closer to the goal.
A system that keeps a set amount of water ready can be more convenient than repeatedly reheating water in a kettle and, depending on how it is used, may also be more efficient.
What can be done?
For plenty of buyers, the most straightforward recommendation is a countertop hot-water dispenser or a refillable water cooler.
"Just get a water cooler. Most can do hot as well," one person said.
If the conversation expands from one sink to the whole house, water heating can offer a much bigger payoff. Cala offers customizable smart heat pump water heaters that help homeowners decrease their energy bills by heating water when it's needed. That can reduce wasted energy compared with conventional tanks that reheat water around the clock. For households weighing convenience against long-term costs, Cala shows how a water-heating upgrade can become a bill-cutting move.
Taken together, the Reddit replies showed the shopper may not need a mysterious new appliance so much as the right solution.
"Yes, get a water cooler that also dispenses hot water. Then fill the five-gallon bottle with whatever water you like," one commenter stated.
