The Heatguard® 115 is a large sized high flow rate Temperature Actuated Mixing Valve that mixes hot water with cold to deliver tempered water at a controlled pre-set temperature.
The Heatguard® 115 is intended for installation at water heater to distribute controlled temperature water throughout the domestic hot water system for larger residential and commercial applications. The valve is factory set to deliver water at a maximum of 120ºF (49ºC), allowing the heater to be set at 140ºF (60ºC) or higher, thus providing a greater effective volume of hot water and reducing the chances of legionella bacteria growth in the water. The outlet water flow rate is 27.2 gpm at 50 psi, making it suitable for larger residential and commercial installations.
The Heatguard® 115 has an outlet temperature range extending to 176°F (80°C), making it ideal for applications in heating systems or in any installation requiring the delivery of reduced temperature hot water.
The Heatguard® 115 is a high quality mixing valve incorporating the latest in thermostatic technology. It features a robust design based on the expertise gained from years of experience in the design and manufacture of safety valves. It incorporates a fast acting, high quality thermostatic element that senses the outlet water temperature and reacts to maintain a stable delivery water temperature even under changing flows or variations in supply temperatures. Every valve is tested for performance on an automated testing station during the assembly process.
The Heatguard® 115 is shipped complete as a kit with your choice of end connections in 3/4", 1” & 1 1/4" sizes. Available end connections are sweat or threaded. All valves are supplied standard with check valves at hot and cold water inlets.

Features and Benefits |
N/A Delivers water at a maximum of 120ºF (49ºC) throughout the system: Safer hot water from all outlets. Allows the heater to be set at 140ºF (60ºC) or higher: Greater effective hot water volume, less chance of legionella within the cylinder. Large sized valve with high flow rates: Single valve can supply controlled water to a large installation. Robust, low complexity construction: Superior reliability, improved user safety. Integral union connections on all three ports: Easy and quick to install and service. Listed by IAPMO and ASSE: Inspector friendly, peace of mind! |
