Portable Water Heaters

Portable water heaters are used for outdoor showers, camping, RV travel, off-grid cabins, horse and pet washing, boat docks, and temporary job site installations. Flow rates on portable models typically range from 1.5 to 3.0+ GPM depending on the unit size and fuel type, providing enough hot water for a single shower or wash station.

The Trade Table carries portable water heaters from Eccotemp, PrecisionTemp, and other leading brands in propane, natural gas, and electric configurations for camping, outdoor showers, off-grid living, and temporary hot water needs.

Portable Water Heaters | Propane Camping Showers & Outdoor Hot Water

A portable water heater connects to a propane tank and a cold water source, heats the water as it flows through an internal heat exchanger, and delivers hot water through a shower head, hose, or faucet attachment. Most units ignite automatically when water flow is detected and shut off when the tap is closed — requiring no electricity for basic operation.

Propane portable water heaters are the most common configuration because they operate independently of electrical power, making them ideal for remote and off-grid locations. A standard 20-pound propane tank can provide multiple hours of hot water depending on the flow rate and temperature setting. Some models include a built-in water pump for drawing water from a bucket, lake, or other non-pressurized source.

Electric portable water heaters plug into a standard outlet and heat water using an electric element — suited for garages, workshops, pool houses, and temporary event setups with electrical access but no permanent plumbing.

Portable Water Heater FAQs

How does a portable water heater work?

A portable water heater connects to a propane tank and a cold water source. When a faucet or shower head is opened, water flows through the unit and passes over a heat exchanger heated by a propane burner. The water exits at the set temperature. Most units ignite automatically when water flow is detected and shut off when the flow stops — no electricity required on propane models with battery or hydro ignition.

How long does a propane tank last with a portable water heater?

A standard 20-pound propane tank typically provides 2 to 6+ hours of continuous hot water depending on the flow rate, temperature setting, and incoming water temperature. Lower flow rates and moderate temperature settings extend tank life. A 1-pound camping propane canister provides approximately 20 to 40 minutes of hot water on most portable units.

Can I use a portable water heater for a camping shower?

Yes. Most portable propane water heaters include or are compatible with a shower head attachment and hose. Flow rates of 1.5 to 2.5 GPM provide a comfortable shower experience similar to a low-flow residential shower head. Many models are designed specifically for outdoor camping shower use and include carrying handles, hanging hardware, and weather-resistant housings.

Do portable water heaters need electricity?

Propane models with battery ignition or hydro-powered ignition do not require any external electricity. The burner lights automatically when water flow is detected. Electric portable models require a standard 120V outlet or dedicated circuit. If fully off-grid operation is required, choose a propane model with battery or hydro ignition.

What is the difference between a portable and a permanent tankless water heater?

A portable water heater is designed for temporary, mobile use — it connects to a propane tank and a garden hose or bucket pump with no permanent installation. A permanent tankless water heater installs in a fixed location with dedicated gas lines, water connections, and venting. Portable models have lower GPM output suited for one fixture at a time. Permanent models deliver higher GPM for whole-home hot water supply.
