    • great tankless water heater
I recently received the thermoMate Tankless Water Heater, and I am very impressed with its functionality, heating performance, and ease of use. The unit is compact and fit perfectly in the available space under my sink, making installation straightforward and convenient. It heats water quickly, providing hot water on demand without the wait associated with traditional systems. The temperature display is easy to read, and the self modulating feature helps maintain consistent performance while using energy efficiently. I also appreciate the solid construction and safety features, which provide added confidence during operation. Throughout installation and use, I experienced no leakage issues, and the connections remained secure. Overall, this tankless water heater delivers reliable hot water, excellent convenience, and great value for anyone looking for an efficient point use solution. ... show more

    • INSTANT HOT WATER RIGHT AT THE SINK - RECOMMENDED!
This little tankless water heater does exactly what it's designed to do — provide hot water almost instantly at a single sink without waiting for hot water to travel from a larger water heater elsewhere in the building. The compact design makes it easy to fit under a sink where space is limited, and I like the digital temperature display and touch controls that make adjustments simple. Once installed properly, it delivers hot water quickly and consistently for hand washing, utility sinks, small office setups, workshops, and similar point-of-use applications. The build quality feels solid, and features like the stainless steel water tube and separated heating element should help reduce scale buildup over time. PROS * Provides hot water within seconds * Compact space-saving design * Easy-to-read digital temperature display * Adjustable temperature settings * Consistent point-of-use performance * Energy efficient on-demand heating * Solid build quality * Good option for remote sinks * Touch controls are simple to use * Fits easily under most sinks IMPORTANT CONSIDERATIONS * This is designed for a single sink or point-of-use application, not whole-house use * Requires hardwired installation * Requires a dedicated 40A circuit and proper wiring * Installation may require an electrician if one isn't already available * Flow rate affects final water temperature * Be sure your electrical system meets the requirements before purchasing OVERALL IMPRESSION If you need near-instant hot water at a specific sink and have the proper electrical setup available, this is a compact and effective solution. It heats quickly, takes up very little space, and eliminates the wait for hot water at point-of-use locations. ... show more
