Specifications side by side

Key specs for choosing a unit

1. Check your fuel source

   Start by confirming which utility is available in your home. Natural gas models like the VancEpic 4.3 GPM unit provide higher flow rates suitable for whole-house use. Electric heaters, such as the 18 kW model, require a dedicated 240V circuit. If you lack gas access, an electric option is your only path. Ensure your current infrastructure supports the chosen fuel type before purchasing to avoid costly retrofitting or installation failures.

2. Assess flow rate needs

   Flow rate determines how many fixtures can run simultaneously. The 4.3 GPM natural gas heater supports multiple showers and sinks for larger families. Smaller units, like the 3.6 GPM model, suit households with lower demand. If you need hot water for two bathrooms at once, prioritize higher GPM ratings. Lower flow rates may result in temperature drops when multiple taps are open, so match the spec to your household size.

3. Verify electrical requirements

   Electric tankless heaters demand significant power. The 18 kW and 14 kW models both require a 240V connection. You must check your electrical panel capacity before installation. The 14 kW unit is compact but still needs specific wiring. Insufficient voltage can prevent the unit from heating water effectively. Consult an electrician to ensure your home can handle the wattage load. Proper electrical setup is critical for safety and performance.

4. Measure installation space

   Physical dimensions dictate where you can mount the unit. The 14 kW electric heater is notably slim, measuring only 3.19 inches in width. This makes it ideal for tight closets or small utility rooms. Larger gas models, such as the 4.3 GPM unit, require more room at 14.4 inches wide. Measure your intended installation area carefully. Ensure there is adequate clearance for maintenance and airflow around the device.

5. Determine venting needs

   Gas models require proper venting to exhaust combustion gases. The 4.3 GPM natural gas heater uses non-condensing venting, which is standard for indoor installation. You need space for vent pipes to exit the home safely. Electric models do not require venting, offering more placement flexibility. If you are installing in a small indoor space, confirm that the venting path is clear and compliant with local building codes for safety.
