Specifications side by side

VancEpic Tankless Water Heaters Overview

This lineup features four distinct models separated by fuel type and installation needs. The VancEpic 4.8 GPM Natural Gas unit is designed for indoor whole-house use with non-condensing venting. For outdoor propane requirements, the 5.3 GPM model provides high output, though it is limited to elevations under 2,000 feet.

Electric options include the 27kW RE27K for robust whole-house flow and the compact 14kW RE14K-C for spaces with limited electrical capacity. The electric units differ in wattage and physical footprint. You can choose based on your available voltage and desired flow rate. Each model targets specific infrastructure constraints rather than offering universal compatibility.

Who VancEpic Range Suits

VancEpic offers a spread from compact electric units to high-output gas heaters. The 14kW electric model is slim at 3.19 inches wide, ideal for tight spaces. The 27kW electric version is wider but lighter. Gas models are bulkier, with the propane unit being the heaviest at 34 pounds. You get options for indoor and outdoor installation. The range lacks smart home integration or digital displays in these specs. It suits homes needing dedicated whole-house heating via specific fuel types, rather than point-of-use fixtures.

Choosing the Right VancEpic Model

1. Match fuel to availability

   Your home’s existing fuel source dictates which unit fits. If you have natural gas lines, the 4.8 GPM Natural Gas model uses non-condensing venting for indoor installation. For propane users, the 5.3 GPM Outdoor Heater offers higher output but requires outdoor placement. Electric models like the 27kW and 14kW units rely solely on electrical power. Check your utility connections first to avoid incompatible hardware purchases.

2. Check installation location

   Indoor units need proper venting, while outdoor models are built for weather exposure. The 4.8 GPM Natural Gas heater is designed for indoor use with non-condensing venting. In contrast, the 5.3 GPM Propane unit is explicitly for outdoor installation. Electric models can often fit in utility closets or garages. Ensure your chosen spot meets the specific location requirements of the unit to ensure safe and compliant operation.

3. Evaluate flow rate needs

   Flow rate determines how many fixtures can run simultaneously. The 4.8 GPM Natural Gas unit suits whole-house needs with reliable flow. The 5.3 GPM Propane model provides even higher output for families with multiple simultaneous uses. Electric options vary by wattage. If you need steady flow for multiple sinks, higher GPM ratings are essential. Match the flow rate to your household’s peak water usage patterns.

4. Verify electrical capacity

   Electric tankless heaters require specific voltage and wattage. The 27kW Electric model needs a robust 240V electrical infrastructure for whole-house hot water. The 14kW Electric unit is a more compact alternative for homes with limited electrical capacity. Both operate on 240V. Before purchasing, confirm your electrical panel can handle the wattage. Higher wattage units deliver more hot water but demand stronger circuits.

5. Consider physical dimensions

   Space constraints influence your choice. The 14kW Electric heater is extremely slim at 3.19 inches wide, making it ideal for tight spaces. The 4.8 GPM Natural Gas unit is larger, measuring 14.4 inches wide and 24.6 inches high. The 5.3 GPM Propane model is also bulkier at 14.2 inches wide. Measure your installation area carefully. Ensure the unit’s width, height, and length fit your available space without obstruction.
