As a gas-fired tankless option with RV-specific features, evaluate ventilation, fuel supply, and clearances required for safe installation. The product description stresses continuous hot water and anti-scald protections.
Feelrogast 8 Gallon Mini Tank

The Feelrogast model is an 8-gallon electric mini tank water heater billed for under-sink or near-point-of-use installation in RVs, campers, food trucks, and similar applications. It emphasizes rapid reheat and stainless steel construction.
- Instant Hot Water: Rapid reheat with a stainless steel heating element for high thermal efficiency.
- Build Quality: 316 stainless steel tank with enamel layers and pressure-resistant construction.
- Safety: Multiple protections including electrical insulation, leakage protection plug, and auto temperature control.
- Mounting: Can be installed wall- or floor-mounted depending on space and plumbing layout.
This product targets point-of-use needs where a small reservoir can reduce cold-water wait times without the complexity of tankless power or fuel requirements. Check amperage and circuit protection requirements before installation.
Briidea RV Electric Hybrid Kit

The Briidea kit is designed to convert existing LP-powered RV water heaters to permit 120V electric heating as a secondary or backup option. It is intended as an add-on to Atwood and Suburban tanks using brass bushing adapters.
- Conversion Concept: Adds electric heating capability so the tank is not wholly dependent on propane.
- Compatibility: Brass bushings available in 1/2″ and 3/4″ sizes to fit common tanks; connects where the anode rod/drain plug is located.
- Controls: Independent switch and adjustable thermostat for user control of electric heating.
- Use Case: Useful for shore power use, reducing propane reliance and providing freeze protection when plugged in.
The kit targets owners who want redundancy or the option to use campsite power. Installation requires mechanical fit with the tank’s anode/drain location and basic electrical wiring following safety codes.
Buying Guide
This buying guide highlights the key considerations when selecting an RV electric heater or electric hot water solution. It covers system types, electrical requirements, installation factors, safety, energy use, and matching product capabilities to real-world RV scenarios.
Heat Type And Intended Use
Clarify whether you need a space heater for living-area warmth or an electric water heater for washing and showers. Space heaters (wall-mounted or portable) focus on ambient air warming and typically require less plumbing. Water heaters fall into two broad categories: mini tank (limited gallons stored, quicker recovery) and tankless (on-demand, continuous flow).
Power Source And Electrical Capacity
RV electrical systems vary: 12V, 120V shore power, and generator output are common. Space heaters at 1500W and electric water heater elements require dedicated circuits and sufficient amperage. Check your RV’s converter/inverter capacity, shore power rating, and circuit breaker sizes before purchase.
Installation And Mounting
Wall-mounted space heaters need clearances and secure mounting surfaces. Mini tanks require plumbing drains or pressure relief provisions. Hybrid kits and tankless units often need panel cutouts and proper venting. Confirm required door sizes, clearances, and whether professional installation is recommended for gas or hybrid conversions.
Heating Output And Capacity
Compare space heater wattage and oscillation features for distribution versus localized warmth. For water heaters, consider GPM (gallons per minute) for tankless units and tank capacity for stored systems. Higher GPM or larger tanks better support showers and multiple simultaneous uses.
Controls, Scheduling, And Smart Features
Smart features like app control, scheduling, and voice commands provide convenience and allow pre-heating on shore power. For water systems, adjustable thermostats and anti-scald protection are important. Evaluate whether remote access and precise temperature control are priorities for your setup.
Safety Features And Certifications
Key safety elements include thermal cutoffs, anti-scald protection, leakage detection, and IP ratings for electrical devices. Look for products with recognized certifications and clear manufacturer guidance on safe operation in mobile environments.
Tank Vs Tankless: Comparison Perspective
Tank systems provide immediate stored hot water and simpler electrical requirements for small tanks, but they have standby losses and limited capacity. Tankless systems offer continuous hot water and reduced standby energy but demand higher instantaneous power or fuel and may require larger venting and installation complexity. Match performance needs to available power and space.
Energy Efficiency And Operating Costs
Electric solutions are generally efficient at point-of-use, especially mini tanks and tankless units that eliminate long plumbing runs. Tankless systems save standby energy but may require more energy during peak demand. For space heating, ceramic PTC elements and variable thermostats can improve comfort per watt.
Compatibility And Retrofit Considerations
Retrofitting an existing RV may require custom door sizes, mounting brackets, or adapter bushings. The availability of multiple door sizes or brass bushings, as noted in some product specs, eases refitment. Measure existing cutouts and confirm part compatibility before ordering.
Maintenance And Longevity
Regular maintenance includes checking anode rods (for tanks), flushing to reduce mineral buildup, and verifying venting and seals for gas components. Tankless systems have water quality sensitivity—hard water may require filters or more frequent maintenance. Assess replacement part availability for long-term serviceability.
Multi-Perspective Comparison Checklist
- Space Needs: Choose a low-profile wall heater for tight cabins or oscillating units for even distribution.
- Power Limits: Match heater wattage to available shore power or generator capacity; avoid overloading circuits.
- Hot Water Demand: Estimate shower and sink usage to choose between mini tank capacity and tankless GPM.
- Installation Complexity: Determine whether you’ll handle DIY or require professional installation for fuel or venting work.
- Backup and Redundancy: Consider hybrid kits to add electric backup to propane systems for flexibility and freeze protection.
Final Fit Checklist Before Purchase
- Measure available mounting space and door/cutout dimensions.
- Verify electrical service (voltage, breaker size, and shore power limits).
- Confirm fuel or venting requirements for gas or hybrid units.
- Assess noise and airflow in the intended cabin location.
- Compare warranty, parts availability, and installation documentation.
