Laing Thermostech Inc.: Hot-Water Recirculation Pump
March 5, 2007
The UltraCirc® 909 instant hot-water recirculation pump is designed specifically for tankless water heaters. A strap-on temperature sensor regulates the system temperature and limits the length of time the tankless heater will be operating during the recirculation period. The system will maintain a constant temperature at all fixtures in the home, providing immediate availability of hot water. The built-in 24-hour timer allows users to select the times of day for the system cycle. The timer can be programmed in half-hour increments. There are multiple on-off settings that can also be programmed. According to the company, the built-in ball valve and check valve make the system simple to install and service.
