Since 1909, Horne Engineering Ltd has specialised in the design and manufacture of thermostatic temperature control solutions for steam and hot water applications across industrial, commercial and institutional sectors.

Our thermostatic technologies are used throughout the food and beverage, brewing, dairy, pharmaceutical, cosmetics, chemical processing, packaging and manufacturing industries, where accurate, reliable and safe hot water control is critical for process performance, hygiene and operational efficiency.

Horne’s original EA-1 thermostatic steam control valve, first developed in 1909, established the company’s reputation for dependable temperature control of hot water storage calorifiers and process vessels. Still manufactured today in sizes DN15–DN50, the EA-1 continues to provide robust and highly accurate control for steam calorifiers, industrial washing systems and storage heating applications.

Complementing this technology is the Horne Steam Injection Heater (SIH), designed for rapid and efficient heating of stored water in tanks and vessels. By injecting finely dispersed steam bubbles directly into the water, the SIH delivers fast and efficient heat transfer with minimal noise, vibration and maintenance requirements due to its simple, no-moving-parts design.

For applications requiring instantaneous large-volume hot water production, the Horne SWM1 Steam-Water Mixing Valve combines steam and cold water to deliver temperature-controlled hot water for wash-down, cleaning-in-place (CIP), and rapid vat or tank filling operations. Both thermostatic and pressure balanced, the SWM1 maintains stable outlet temperatures even under highly demanding and fluctuating inlet conditions.

The accompanying performance demonstration videos illustrate the SWM1 maintaining stable outlet temperatures under rapidly changing inlet pressure and temperature conditions, while the simplicity, efficiency and effectiveness of direct steam injection heating is also shown and explained.

Horne Engineering invented the thermostatic water-water mixing valve in the early 1920s – named the Hot Water Blender at the time – pioneering a technology that would go on to become fundamental to safe hot water distribution worldwide. Over more than a century, this innovation has evolved into a comprehensive range of thermostatic mixing valves from DN15 to DN50, supporting applications from point-of-use blending through to high-flow group distribution systems and industrial process water temperature control.

Horne’s large-bore (DN32-DN50) thermostatic mixing valves are widely suited to industrial hot water distribution, wash-down systems, process heating and low-temperature hot water generation associated with modern plant and energy systems. Today, Horne thermostatic mixing valves are also widely applied within low-carbon heating installations, including Mitsubishi Electric Q-ton heat pump systems, where accurate and reliable blending of stored hot water is essential to achieving safe distribution temperatures, stable operation and system efficiency.

Combining long-established thermostatic expertise with modern manufacturing, Horne Engineering continues to deliver robust, serviceable and high-performance temperature control products engineered for demanding environments where reliability, safety and operational continuity matter most.
