I'm a truck driver,and before I got this,I had to shower at rest areas,which was very inconvenient with long lines.Now that I've found this water heater,I can have a hot shower wherever I am.I'm so grateful!

How long is the hose for the shower head?

Kohree

2 meters

does this take a pressurised water system or a separate pump?

Kohree

This Kohree Helios 20 Pro is designed for flexible outdoor use. With the included independent pump, you can draw water from non‑pressurized sources like buckets or water bags—ideal for off‑grid camping. Prefer a pressurized setup? Simply connect it to a standard faucet or RV water supply. Its built‑in smart chip maintains stable temperatures and adapts smoothly to changing water pressure.

Are there spare parts available such as pumps and shower heads, fittings? Also, should my pump shut off when i use the pause button on the shower head, mine does not and pump is deadheading.

Kohree

This portable propane water heater kit includes the shower head, shower hose, and all necessary fittings. Please note that the water pump is not included and must be provided by you. For proper operation, please ensure the pump remains running while the shower is in use.

Greetings. Can u hook a water hose up to this portable hot water heater or is the pump all you can use ?
Thank you for your time
