HOTTAP Defined

The HOTTAP Outing Kit is a portable hot water system providing on-the-go hot showers when wild camping. Designed for durability and user-friendliness, it elevates outdoor hygiene for a more comfortable experience.

No longer reliant on heating a bucket of water, this all-in-one solution combines a water heater, showerhead, and pump, suiting numerous camping and outdoor needs.

The HOTTAP is designed to conveniently heat and deliver water for showering, washing dishes, cleaning your gear, or rinsing down your dog.

Specification Summary

Engineered to residential standards, HOTTAP boasts top-tier specifications. It delivers continuous hot showers, with an impressive 15-hour runtime on a single 20-pound propane tank.

Operating with a quality 37,500-BTU burner, HOTTAP ensures a piping hot shower, even in winter. Offering a flow rate of up to 1.6 gpm, it effortlessly handles any hair type — including my long, thick diva mane!

Utilize your HOTTAP alongside a jerrycan. Or, employ the two-stage water filter to draw water from a nearby natural freshwater source, e.g., a creek or lake, pumping it to your camp spot. The pump primes to 6 feet and propels water up to 100 feet uphill. With an IPX3 rating, the pump withstands rain, hail, and sunshine exposure. Plus, the pump won’t be harmed when running dry if water is scarce.

Joolca Hot Shower Usage

Straightforward enough; attach the water heater to a propane or butane gas source and submerge its pump into a water source. The water is drawn through the system, heated, and expelled through the showerhead, delivering a refreshing cascade of warmth.

River Filter

The intake incorporates a two-stage filter that eliminates all but the tiniest sediments. Its durability allows for immersion in shallow creeks, for instance. Maintenance is pretty effortless — no tools are required. Simply untwist the cover, take it apart, rinse with water, and reassemble it.

Target Audience

Joolca’s portable hot water system appeals to a broad spectrum of outdoorsy folks. It’s a blessing for campers who crave home comforts in nature. Whether you’re a family on a camping trip, a van lifer needing rejuvenation, or an overlanding couple exploring rugged terrains, the HOTTAP invites you to elevate your camping experience with heated water.

Camping With the HOTTAP: A Personal Experience

Testing the product in various camping situations for a year of overlanding in our Toyota Hilux validated its claims. Whether among rugged terrains in northern Spain, along Scotland’s windy coastline, or random parking lots — far away from campsite facilities — the Joolca system bridged the gap.

Upside in the Field

Harnessing even the tiniest streams, shampooing twice and conditioning once induced overlanding bliss. The instant gratification of piping hot water at the touch of a button elevated morning rituals and end-of-day refreshments.

The Joolca unit surpassed my expectations, turning our post-trek campsite into a euphoric oasis. At natural water sources, it delivered that shower-fresh feeling from making contact with boundless hot water and soap, limited only by the gas onboard our rig.

Downside in the Field

Admittedly, when I could not pump water from a natural source, relying on a jerrycan instead, I opted for a swift body and hair wash. This is a non-issue for those with larger water supplies and/or short hair.

Tips for Enhancing Your HOTTAP Experience 

  • If using a small 1-pound gas canister, place it in a bowl of boiled water. This maintains a consistently hot shower temperature, as occasional drops in temperature can occur. 
  • On windy days, position the shower area away from the wind. And construct a sturdy windbreak around the heating unit. Neglecting these steps may extinguish the flame, necessitating a restart.

Joolca HOTTAP: Price & Value

The Outing Kit is an investment that comes with a $449 price tag — reflecting its innovation, ease of use, and functionality. While the upfront cost might seem steep, cry once while considering the convenience, enhanced hygiene, and comfort it brings to your sweat and body-odor-inducing outdoor escapades. If you prioritize these needs, the ensemble is an invaluable addition to your gear arsenal.

Essentials, Outing, or Nomad Kit?

While the Outing Kit includes a 12V pumping kit for wild water sources, consider the Essentials or Nomad kits as the basic or more fully featured Joolca alternatives, respectively. 

  • The Essentials Kit is for pressurized water access from pumps, mains, or planned systems. It includes a heater with portable feet, gas hose, 5m shower hose, head, and magnetic holder.
  • The Nomad Kit expands Outing. It features a sink/tub combo, T-splitter, hot water outlet hose with Faucet Tap, and a stand doubling as a tub storage divider.
