Specifications side by side

Orbek Tankless Water Heater Overview

You will not find high-volume multi-bath systems or outdoor propane heaters in this list. If you need whole-house hot water, the 120,000 BTU natural gas model fits. For travel, the 60,000 BTU propane units work well. There are no large-capacity propane home heaters here. Choose based on your fuel source and space constraints.

How to Choose the Right Orbek Heater

1. Match Fuel Type to Setup

   Orbek offers propane, electric, and natural gas options. Propane units like the HRU-RG060-A1 suit RVs using 12V DC power. Electric models require a 240V circuit and are best for indoor spots with stable wiring. Natural gas heaters need a gas line and outdoor venting. Check your available fuel source first. Mismatching fuel types leads to installation failure. Select the model that aligns with your existing infrastructure to ensure reliable operation without complex modifications.

2. Check Dimensions for Space

   Size matters for tight installations. The 14kW electric model measures 9.5 by 9.5 by 14.2 inches, fitting small indoor closets. RV units are cubic, measuring 12.7 inches on each side. Whole-house gas models are larger, reaching 22.8 inches in height. Measure your intended mounting area carefully. Ensure there is enough clearance for maintenance access. Compact units save space but may have lower flow rates. Larger units provide more hot water but need more room. Verify fit before purchasing.

3. Evaluate Flow Rate Needs

   Flow rate determines how many fixtures can run simultaneously. The indoor propane model delivers 4.3 GPM, suitable for homes with space limits. RV units provide on-demand water for showers and sinks but may not support multiple high-flow uses. Higher BTU ratings generally support better flow. Consider how many people use hot water at once. If you need simultaneous showering and dishwashing, choose a higher capacity unit. Lower flow models work well for single-use scenarios or small RVs.

4. Confirm Installation Location

   Location dictates which model you can use. Indoor propane heaters like the HW100 require proper venting and air supply. Outdoor natural gas units, such as the HW120A1W-NG, withstand weather but need a gas line. Electric heaters are versatile for indoor installation but need electrical capacity. RV units are designed for mobile use but can be stationary. Check local codes for venting and clearance. Wrong placement causes safety hazards and voids warranties. Match the unit to your specific installation environment.

5. Verify Electrical Requirements

   Electric tankless heaters demand specific voltage and amperage. The 14kW model requires a 240V circuit. Ensure your home or RV can supply this power. Propane and natural gas models do not need high-voltage electricity, though they may use low-voltage controls. RV propane units often use 12V DC power. Check your electrical panel capacity before buying an electric model. Inadequate power causes tripping or failure. Confirm your wiring supports the wattage. Proper electrical setup ensures safe and efficient heating performance.
