Product Description
The One That Fits When Nothing Else Does
You know the calls. The customer says they need hot water under the kitchen sink, but the garbage disposal takes up all the space on the right side. Or they're remodeling a bathroom with a shallow vanity, and a standard tall tank won't clear the drawer. Or it's an RV build where every inch is already spoken for.
Most mini water heaters force you to work around them. Ours works around you.
Our Multi-Position Series Handwash Oversink Water Heater gives installers options. Mount it vertically. Mount it horizontally. Bring the water in from the top or the side. However, the space is laid out, and this unit finds a way.
What Makes It So Flexible?
Horizontal or Vertical – Your Choice
A switch inside lets you change the orientation. The heating element and thermostat adjust automatically. You're not stuck with one configuration.
Top or Side Water Connections
Pre-installed fittings let you connect from above or either side. No need for extra elbows or complicated pipe routing. Just pick the direction that works and connect.
Compact Footprint
Even with all this flexibility, the tank itself is slim. The 2.5-gallon model is just 14 inches tall in vertical mode, or 12 inches wide in horizontal mode. It slides into spaces other units can't touch.

Where Installers Love This Unit
Under Kitchen Sinks
Garbage disposal on the right? No problem. Run the water in from the left side, mount the unit horizontally to stay below the disposal height. Done.
Bathroom Vanities
Shallow cabinet? Mount it horizontally against the back wall. Deep but narrow? Stand it vertically in the corner. Works either way.
RV and Marine
Space is never straight or level in a vehicle. Being able to orient the tank to fit the available cavity is a game-changer for builders.
Basement and Utility Rooms
Low ceiling? Horizontal mount. Narrow space between studs? Vertical mount. Adapt to the building, don't fight it.
Bar and Restaurant Sinks
Under-bar space is chaotic-glass washers, ice bins, storage. Our unit tucks into whatever pocket is available.
Built Just as Tough
Just because it's flexible doesn't mean it's flimsy. Multi-Position Series has the same internals as our fixed-orientation units:
Glass-lined steel tank – vitreous enamel, not plastic
Magnesium anode – replaceable, extends life
Incoloy 825 element – resists scale and burnout
25mm PU foam insulation – low standby loss
Adjustable thermostat – 50°F to 160°F
T&P valve included – ASME certified
Factory Strength
What Installers Tell Us
"I had a job in a 1920s house. The sink base cabinet was tiny, and the plumbing came in from a weird angle. This unit saved me. Mounted it sideways, connected from the top, and it fit like it was made for that space."
"We build custom vans. Every van is different. Stocking one heater that works in any orientation cuts our inventory in half."
Our Factory: 20+ Years of Listening
We didn't invent the multi-position heater overnight. It came from years of talking to installers, hearing their frustrations, and going back to the drawing board. Our engineers spent six months prototyping orientation switches and connection layouts until they worked smoothly.
That's how we operate. Listen, design, test, improve. We've been at it since 1998, and we're still learning.
