Improving Hot Water Distribution and Saving Energy Using Advanced Recirculation Controls

Advanced controls for central domestic hot water recirculation pumps Reduces Boiler Fire Time (Saves Gas) Reduces Pump Run Time (Saves Electricity) Reduces Wear and Tear on Pipes (Pinhole Leaks)

1 ) Cold water supply 2) Water heated to approximately 140 ℉ 3) Hot water is continuously circulated throughout the building from the storage tank 4 ) As water is being circulated, the pipes are constantly radiating heat into the surrounding environment 5) When water returns, it is much cooler from the heat loss, so the boiler constantly fires on to reheat the water

If there is no user demand for hot water If there is already hot water at the point of use

Uses sensors that detect demand and water temperature only runs when needed Runs about 1 hour per day total, instead of 24/7 Heat losses reduced, boiler fires up 10-30% less often
