Description

[Max 3.06 GPM & 75,000 BTU] - The ThermoMate instant water heater reliably delivers a comfortable single shower (2 GPM at 105°F) even when inlet water is as low as 52°F. If the summer inlet temperature reaches 65°F, it maintains full shower performance and can additionally supply a faucet at 0.5 GPM. No waiting time, no cold water shocks, perfect for the bathroom or kitchen.

[Safety & Reliable] - This gas tankless water heater integrates 8 protections: boil-dry, freeze, flame-out, overheating, over-temperature, pipe blockage, high-temperature lock, and excessive air pressure. Equipped with 4 ceramic heating cores, it auto-activates frost protection when temperatures hit 41°F (5℃). The energy-smart system uses minimal electricity to generate gentle warmth, preventing pipe ice buildup without high energy costs.

[Energy Efficient & Save Money] – Built with an oxygen-free copper heat exchanger for efficient heat transfer and corrosion resistance, this natural gas water heater delivers up to 98% thermal efficiency with a UEF of 0.81. Its energy-efficient design reduces energy waste and can lower annual operating costs by approximately 30% compared with traditional water heaters.

[Precise Temperature Control] – Advanced water flow and temperature sensors continuously adjust water flow and gas input to maintain temperature stability within ±1°F. The built-in control chip adjusts heating output 20,000 times per second, helping maintain consistent hot water comfort even when water demand or incoming water temperature changes.

[Easy to Install & Save Space] – Designed for everyday household showering, this compact indoor water heater measures just 21"H × 13"W × 7"D and takes up less than one-third the space of traditional tank models. Standard 3/4" NPT water inlet/outlet connections, a 1/2" NPT gas inlet, a 3" OD vent connection, and UL-approved 120V plug simplify installation in most homes.

[Smart Diagnostic Display] - Easily adjust water temperature (90–140°F) and keep track of flow, fan, and flame status on the 3.5-inch LED display. Advanced error codes allow fast troubleshooting, while the UL-certified 120V/5-foot cord keeps the system powered and monitored at all times.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $40 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for thermomate products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
