Heating Performance and Efficiency
Rapid Heating Capability
One of the most important features of the BISELONG 8 Gallon Under Sink Water Heater is its 316 stainless steel heating element. This component is known for:
- Excellent corrosion resistance
- High durability
- Stable heat transfer
The system reaches up to 99% thermal efficiency, meaning most of the electrical energy converts directly into heat.
The adjustable thermostat allows users to set water temperature between 86°F and 167°F. This range accommodates:
- Hand washing
- Dish cleaning
- Food preparation sanitation
- Light laundry tasks
Because it stores heated water, users do not experience sudden temperature drops during moderate use.
Tank Construction and Durability
Durability is a major advantage of this model.
2.0mm Thick Stainless Steel Tank
The internal tank is constructed from 2.0mm thick stainless steel, offering:
- Pressure resistance
- Structural strength
- Reduced deformation risk
This heavy-duty construction helps prevent internal damage under maximum pressure of 109 PSI.
Advanced Enamel Coating
The tank interior includes a 500–800μm enamel coating applied through a dual-layer process. This coating:
- Prevents cracking
- Reduces rust formation
- Minimizes leaks
- Protects against mineral buildup
The enamel layer extends tank lifespan and improves long-term reliability, especially in areas with hard water.
Installation and Setup
Flexible Mounting Options
The BISELONG heater supports multiple installation styles:
- Wall-mounted
- Rack installation
- Floor placement
- Hidden under-sink installation
This flexibility makes it ideal for compact kitchens, food trucks, and RV cabinetry.
Electrical Requirements
The unit operates on standard household 110V–120V power. It includes a 44-inch power cord with plug but requires a dedicated 20-amp circuit breaker for safety.
This allows installation without specialized high-voltage wiring, unlike many tankless units that require 240V circuits.
Plumbing Connections
The heater uses:
- 1/2″ NPT connectors
- 3/8″ water fittings
Important notice: The pressure relief valve must be installed on the blue end of the water inlet to ensure safe operation.
Professional installation is recommended for optimal safety and compliance with local plumbing codes.
Safety Protection Systems
Safety is reinforced through multiple protective mechanisms.
Electrical Insulation Protection
The water inlet and outlet feature insulated connections to prevent electrical hazards.
Leak-Proof Plug
A high-quality plug design reduces the risk of water-related electrical issues.
High-Temperature Limiting Device
An internal temperature limiting system prevents overheating. If water temperature exceeds safe limits, the heater automatically regulates output.
Automatic Temperature Control
The thermostat maintains consistent water temperature, preventing scalding risks when properly adjusted.
Multi-Layer Safety System
Combined insulation, pressure resistance, and automatic controls ensure safe daily operation in residential and commercial settings.
Applications and Versatility
The BISELONG 30L electric storage tank heater is highly adaptable.
1. RV and Travel Trailers
Compact dimensions and 110V compatibility make it suitable for mobile living spaces.
2. Food Trucks
Food truck operators benefit from reliable hot water storage for cleaning utensils and maintaining hygiene standards.
3. Small Kitchens
Under-sink installation eliminates long pipe runs and reduces water waste.
4. Garages and Workshops
Ideal for handwashing stations or cleaning tools.
5. Salons and Offices
Provides consistent warm water for handwashing and sanitation.
Performance Comparison: Tank vs Tankless
| Feature | BISELONG 8 Gallon Tank | Typical Small Tankless |
|---|---|---|
| Water Supply | Stored 8 gallons | On-demand |
| Voltage | 110V–120V | Often 240V |
| Installation | Plug-in + 20A breaker | Hardwired |
