Thermomate vs VancEpic Spec Comparison
Fuel type
The Thermomate runs on electricity, requiring a standard 120-volt outlet and a 1.44 kW power draw. This makes it suitable for locations with easy access to power but no gas line. The VancEpic uses natural gas, delivering 110,000 BTU of heating power. Gas units typically offer lower operating costs per gallon of hot water compared to electric resistance heating. You must have a gas line and proper ventilation for the VancEpic. If you rely on grid electricity alone, the Thermomate is the only viable option here. Your home’s existing infrastructure dictates which fuel source you can actually use.
Flow rate
The VancEpic provides a continuous flow rate of 4.8 gallons per minute (GPM). This capacity allows it to support multiple outlets, such as a shower and a kitchen sink, simultaneously without significant temperature drops. The Thermomate is a small storage tank with a 6.5-gallon capacity. It does not have a continuous flow rate rating because it stores hot water and reheats it. It is designed for point-of-use applications, like a single bathroom sink or a small kitchen. You cannot run a shower from the Thermomate. If you need hot water for more than one fixture at a time, the VancEpic is the clear choice.
Installation location
The Thermomate is designed for under-sink or counter installation. Its compact dimensions of 17.7 x 17.7 x 14.6 inches allow it to fit in tight spaces. It plugs into a standard 120V outlet, making it a plug-and-play solution for many homes. The VancEpic is an indoor unit that requires more space, measuring 24.6 x 14.4 x 14.4 inches. It also requires gas line connections and specific venting for combustion gases. You cannot install the VancEpic in a closet without proper ventilation. The Thermomate offers greater flexibility for small spaces and renters who cannot modify gas lines.
Temperature control
The VancEpic features precise temperature control, maintaining water temperature within ±1°F. It uses intelligent gas and temperature linkage to adjust heating output automatically. This prevents sudden fluctuations when other water sources are used. The Thermomate offers three manual temperature settings, ranging from 50°F to 149°F. You must adjust the thermostat dial to change the water temperature. It lacks the automatic modulation of the VancEpic. If you prefer stable, consistent water temperatures without manual adjustments, the VancEpic provides superior precision. The Thermomate requires you to set and forget a specific setting.
Build quality
The Thermomate uses a glass-lined tank to prevent corrosion and improve insulation. It includes a temperature and pressure relief valve and is UL Listed for safety. The VancEpic features an oxygen-free copper heat exchanger. Copper transfers heat faster than steel tanks and resists corrosion better. This design aims for longer durability and consistent performance. The VancEpic also includes a brushless DC exhaust system and multiple safety safeguards. The Thermomate is built for longevity in a storage context, while the VancEpic is built for efficient heat transfer in a tankless context. Both units prioritize safety certifications and durable materials.
Which unit fits your home needs
