This ThermaQ Touch electric water heater diers from a conventional storage type mini water
heater, in that it doesn’t store hot water. Instead, water is heated instantaneously as it ows
through the unit. The powerful heating elements are activated by a ow switch as water is
drawn from a hot water faucet connected to the appliance. Due to the absence of standby loss, the Touch has greater energy eciency than storage type water heaters. The unit is
incorporated with several safety devices and will continuously supply hot water for as long as
the faucet is open. In summary, the unit has the following features:
1. Tankless, instantaneous heating for on demand hot water, no pre-heating, no stand-
by heating loss energy-saving.
2. High strength ABS splash proof casing, stainless steel heating element.
3. Compact appearance and unlimited supply of hot water.
4. Easy installation, heater can be installed above or under sink. A power cord is
equipped.
5. Easy operation, the heater provides hot water with constant temperature.
6. Micro-computer control, Adopting patent heating technology. Water is completely
separated from electricity by multi-layered composite nano-insulation material.
7. High-temperature protection: when the outlet water temperature reaches 65°C or
more, the appliance will work to avoid scalding and will automatically adjust while
the temperature drops to a more desirable value.
