A shower that swings from comfortable to cold and back is the thing that ruins camping for people who otherwise love it, and it is why the Nano 3 Ultra is our top pick. CAMPLUX rates the unit at plus or minus one degree, and the controls are built around that promise: two buttons instead of a knob you nudge with a soapy hand. You set a number, you step in, and it stays there.
The kit is unusually complete. Heater, 12V pump, shower head and bracket, gas regulator — a bucket of water and a propane bottle finish the installation, with no pump to buy separately and no plumbing to improvise. The 4,000 mAh battery pushes water for up to 100 minutes and reaches 80 percent in about 90 minutes, which covers a weekend of short showers without an outlet. We also appreciate the cold-water mode: a long press runs the pump without firing the burner, which is what you want for rinsing dishes or hosing off a dog.
Twenty thousand BTU is the modest end of this group, and it defines the job. Fed from a bucket of water already at air temperature, it makes a genuinely hot shower; fed from a near-freezing creek in October, it wants a lower flow to keep the temperature up. At 17.6 pounds it is a two-hand carry, and the price is at the top of this page. Longevity is the open question — the failure to plan around is a unit that quits inside six months, which is what the one-year warranty is for, so keep the receipt.
What We Like
- Holds water temperature within about a degree
- Complete kit: pump, shower head, regulator
- Up to 100 minutes of pumping per charge
- CSA certified with a 122 °F overheat cutoff
Worth Noting
- Premium price for a 20,000 BTU heater
- Cold inlet water and cold weather cut performance
We recommend it to anyone who wants a hot shower that stays at the temperature they set, and does not mind paying for the pump and battery in the same box.
