In many traditional hotels, hospitals, and luxury high-rises, hot water circulation pumps run 24/7 to ensure instant hot water at the tap. This results in massive "standby heat loss" from the pipes and unnecessary electricity consumption. Demand-controlled Recirculation is a smart technology that only activates the pump when it senses a need—either through a flow sensor, a push button, or a scheduled smart timer.
EKG (Malaysia) Sdn Bhd specializes in retrofitting and installing these intelligent systems, allowing facility managers to provide the luxury of instant hot water while slashing energy overheads and carbon footprints.
A demand-controlled system transforms a "dumb" pump into a "responsive" one. Here is the typical sequence of operation:
The Trigger: A guest turns on a hot water tap, or a motion sensor in the bathroom detects presence.
The Activation: The controller instantly signals the Circulation Pump to start.
The Circulation: The pump rapidly pulls cooled water out of the hot water lines and sends it back to the heater, replacing it with fresh hot water.
The Shut-off: A temperature sensor at the furthest point of the loop detects when the water is hot and automatically shuts the pump off to save energy.
Significant Energy Savings: By only running the pump for a few minutes an hour instead of 1,440 minutes a day, electricity and fuel (gas/electric heating) costs are dramatically reduced.
Reduced Equipment Wear: Limiting pump run-time extends the life of mechanical seals, bearings, and the water heater itself.
Water Conservation: Users no longer have to run the tap for several minutes while waiting for water to get hot, saving thousands of liters per year.
Compliance & Sustainability: Helps buildings achieve higher energy efficiency ratings and meet ESG (Environmental, Social, and Governance) goals.
We install high-precision flow and temperature sensors that communicate with your Building Management System (BMS) or standalone smart controllers.
We pair these systems with Variable Frequency Drives (VFDs) to ensure the pump starts softly and operates at the exact pressure needed to move water through the building without causing "water hammer."
A smart pump is only effective if the pipes can hold heat. We provide thermal imaging and re-insulation services for hot water headers to minimize heat loss during the "off" cycles.
We provide scheduled maintenance to clean strainers and calibrate sensors, ensuring the system never leaves a guest waiting for hot water due to a sensor fault.
Technical Precision: We understand the hydraulic balance required to make recirculation fast and effective.
ISO-Certified Quality: Every installation follows strict international standards for plumbing and electrical safety.
Localized Expertise: Based in Selangor, we understand the specific water pressure and temperature challenges of the Klang Valley.
