Different Components of InstaShower 8Pro, 55,000 BTU RV Tankless Water Heater

The InstaShower 8Pro, 55,000 BTU RV Tankless Water Heater, is a complex system comprised of various components that work together to provide efficient and continuous hot water. Some of the key components of the InstaShower 8Pro are:

Mixing Tank:

A mixing tank or thermostatic valve can regulate the water temperature that comes out of the faucet to prevent scalding by mixing the hot and cold water in appropriate ratios and maintaining a consistent temperature. By adding a mixing tank on the hot water line, it can increase the overall water output by aiding in regulating the water temperature which allows a higher volume of hot water to flow out at a consistent temperature.

Heat Exchanger: 

The heat exchanger is responsible for transferring heat from the burner to the water, allowing it to reach the desired temperature. It ensures rapid heating and efficient energy utilization.


The burner is the heat source of the water heater. It ignites and combusts propane gas to generate the necessary heat for heating the water. The InstaShower 8Pro is equipped with a powerful 55,000 BTU burner for quick and effective water heating.

Water Flow Sensor: 

The water flow sensor detects the flow of water through the unit. It activates the heating process when water is flowing and deactivates it when there is no water flow, optimizing energy efficiency.

Control Panel: 

The control panel allows users to adjust and monitor the water heater settings. It typically includes temperature controls, power on/off buttons, and display indicators for easy operation and monitoring.

Venting System: 

The venting system is responsible for safely expelling combustion gases from the water heater. It ensures proper ventilation and prevents the accumulation of harmful gases inside the RV.

Pressure Relief Valve: 

The pressure relief valve is a critical safety feature that releases excess pressure within the water heater, preventing potential damage or accidents caused by overpressure.

Water Inlet and Outlet: 

These are the entry and exit points for the water in the system. The water inlet supplies cold water to the water heater, while the outlet delivers hot water to the desired faucets or showers.

Gas Supply Connection: 

The gas supply connection is where the propane gas is connected to the water heater. It ensures a steady flow of fuel for the burner's operation.
