The Space Problem: Real, and Getting Worse
Walk through any new apartment building or renovated home. What do you see? Smaller kitchens. Compact bathrooms. Vanities that barely hold a trash can, let alone a water heater. Mechanical spaces that seem like an afterthought.
Yet people still need hot water at those sinks. They still want the convenience of instant hot water without waiting for it to travel from a distant tank.
The problem isn't demand-it's space. Standard mini tanks, even "compact" ones, often don't fit in the tightest spots. We kept hearing from contractors: "We need something smaller. Something that actually fits in these tiny cabinets."
So we built it.
Our XS Series Under-Cabinet Electric Water Heater is, quite simply, the smallest unit we could engineer while maintaining real performance and durability. It's designed for those impossible spots where nothing else fits.
Product Advantages and Applications
How Small Is "XS"?
Let's put it in perspective:
| Unit | Height | Width | Depth | Cabinet Space Needed |
|---|---|---|---|---|
| Typical "Compact" 2.5 gal | 15" | 14" | 14" | 2.0 cu ft |
| Our XS Series 2.5 gal | 12" | 11" | 10" | 0.8 cu ft |
That's 60% smaller than the average compact unit. It fits in cabinets where nothing else will. Underbar sinks with garbage disposals already take up space. In RV bathrooms, every inch is precious. In tiny home kitchens, where storage is at a premium.

Where Nothing Else Fits: Real Applications
Under-Bar Sinks
Commercial bars have limited under-counter space-glass rinsers, dump sinks, and storage. Our XS slides into gaps that other units can't. One bar owner told us, "I've wanted hot water at this sink for years. No unit would fit. Yours did. Finally."
Bathroom Vanities
Modern vanities are shallow. Drawers take up space. Our XS mounts vertically or horizontally-tuck it in the back corner, behind the drawer bank, and still have room for cleaning supplies.
RV Kitchens
RV cabinets are famously tight. Our XS is a popular upgrade for van conversions because it fits in the small cabinet under a galley sink without stealing precious storage.
Tiny Home Lofts
Tiny homes maximize every inch. Some bathrooms are essentially a closet with a toilet and a shower. Our XS mounts on the wall behind a small cabinet door, out of sight, out of the way.
Office Coffee Stations
That little sink in the break room? The cabinet underneath usually holds trash and cleaning supplies. Our XS shares the space without forcing a choice between hot water and storage.
Designed for Tight Spots, Not Tight Budgets
Making something small usually means compromise. Not here. The XS Series includes features you'd expect in larger units:
Glass-lined tank – vitreous enamel, not cheap plastic
Magnesium anode – corrosion protection, replaceable
PU foam insulation – CFC-free, 25mm thick
Adjustable thermostat – 50°F to 160°F range
Temperature-pressure relief valve – included, standard
Multi-position mounting – vertical or horizontal

"We build custom vans. Space is currency. The XS lets us offer hot water without sacrificing the cabinet space clients want for storage." - Van conversion shop owner
