InstaShower 8 Pro Rv Tankless Water Heater Review: 60,000 BTUs of Propane Heat

What the InstaShower 8 Pro Is, and Who For

FOGATTI InstaShower 8 Pro heats water at a 2.9 gallons per minute (GPM) flow rate for users requiring consistent output at elevations up to 9800 feet.

A 2.9 gallons per minute (GPM) flow rate allows for a steady stream of hot water that does not fluctuate when the shower head is opened fully. For those upgrading from a standard tank, this means the water temperature remains stable because the heater adjusts its flame intensity during the summer to prevent overheating.

The FOGATTI InstaShower 8 Pro delivers this consistent flow while utilizing a propane fuel source and a 60,000 BTUs heating capacity. It also includes a remote control, which allows for operation without needing to manually adjust the unit during a shower.

We evaluated 38 rv tankless water heaters and selected 15 for a full review based on being the most-rated products that pass screening, with at most 2 per brand. This model was included because it has 968 buyer ratings, the 1st most of the 38 screened. Our full review is based on a data-driven spec breakdown of the options we compared.

The Short Answer on the InstaShower 8 Pro

Best for: You need to maintain a consistent hot water flow at high elevations up to 9,800 feet while using a propane fuel source.

The InstaShower 8 Pro is a practical choice for these requirements at the $629.99 price point.

The Numbers on the Spec Sheet

The 60,000 BTUs of the InstaShower 8 Pro measures the total heat energy produced per hour.

Before You Buy: Rv Tankless Water Heater Checklist

The first thing to check is the BTU output relative to your specific environment to ensure consistent water temperature.

• ☐ Confirm the heater provides 60,000 BTUs — a lower output can cause a flow rate drop, where the unit shuts off or provides cold water if your shower head’s pressure exceeds the heater’s capacity.
• ☐ Verify the 15″x15″ door size fits your mounting area — choosing a unit with a larger footprint may require you to modify your cabinetry or shower stall.
• ☐ Check that your propane supply can support the 60,000 BTU demand — insufficient fuel flow will prevent the unit from reaching its rated heating capacity.
• ☐ Measure your drainage path for condensate — improper drainage leads to internal moisture buildup and premature electronics failure.
• ☐ Confirm your RV is rated for 9800 feet — while this unit operates at that elevation, your specific plumbing and gas lines must also be compatible with high-altitude pressure.

You should not buy the InstaShower 8 Pro if your installation site lacks a dedicated path for condensate drainage or if your existing mounting space is smaller than the 15″x15″ door footprint.

Practical performance results for this Rv Tankless Water Heater

60,000 BTU Heating Capacity

The InstaShower 8 Pro provides 60,000 BTUs of power, which is the total heat energy produced per hour to heat your water. This capacity allows you to maintain a consistent flow of hot water for a full shower without the unit shutting off due to a lack of heating power. Since 60,000 BTUs is the minimum output required to maintain consistent flow rates at high altitudes or in extreme cold, this capacity ensures you have sufficient heat for heavy-use scenarios.

A 2.9 gallons per minute (GPM) flow rate works alongside this heating capacity to deliver a steady stream of hot water. You should confirm your shower head’s flow rate before ordering, as a flow rate that exceeds the heater’s capacity will result in a drop in water temperature. This specific output provides enough power to run a shower for 10 minutes without a flame out, a common failure mode where incorrect gas pressure causes the unit to cycle off.

High Altitude Performance up to 9800 Feet

You can use the InstaShower 8 Pro while camping in the mountains because it is rated to operate at elevations up to 9800 feet. High altitude affects burner efficiency, but this unit provides the 60,000 BTU output necessary to maintain consistent flow rates in thin air. This ensures you don’t experience a flow rate drop when using the heater in high-elevation environments.

The 9800-foot rating indicates the unit can handle the specific atmospheric conditions of mountain travel. Because the heating capacity is already at the category’s minimum requirement for high-altitude consistency, you can rely on the unit to provide hot water in those environments.

How variable flame intensity controls conserve propane during summer

The InstaShower 8 Pro features flame intensity control that adjusts during the summer to prevent overheating and conserve propane. This adjustment helps manage the heat energy produced per hour based on the external temperature. By regulating the flame, the unit helps you extend your fuel supply during months when the ambient air is already warm.

This control mechanism acts as a safeguard against the unit running too hot when the incoming water temperature is high. It allows the heater to operate more efficiently by only providing the necessary amount of heat to reach your desired temperature. This feature helps prevent the unit from overworking the propane supply during the warmer months of the year.

What the price buys in terms of high altitude flow

Running out of hot water mid-shower is a common issue when an RV heater lacks the capacity to maintain flow at high altitudes. The InstaShower 8 Pro provides 60,000 BTUs of power output, which is the minimum output required to maintain consistent flow rates at high altitudes or in extreme cold. Because the unit provides 60,000 BTUs, it has enough capacity to maintain hot water at 10,000 ft elevation and run a shower for 10 minutes without a flame out.

The InstaShower 8 Pro is priced at $629.99, which sits $26 below the $656 average of the similar rv tankless water heater products we compared it against. At this price point, you receive a unit with a 2.9 gallons per minute (GPM) maximum flow rate and a 9800 feet altitude rating. You get a propane-fueled system that includes a remote control and CSA Certification, which ensures the unit meets safety standards for gas pressure and electrical components in North America.

While some models in the category do not state a specific altitude rating, the InstaShower 8 Pro explicitly supports operation up to 9800 feet.

You can expect to use a modest amount of propane during long showers because the unit features flame intensity control, which adjusts during summer to prevent overheating and conserve propane. The specific propane consumption rate is not stated in the product data, but the 60,000 BTU output determines the total heat energy produced per hour during operation.
