application                              

COMFORT circulates hot water to the water facility and returns it to the water heater by using the return pipe (5) to the hot water supply pipe (6), thereby providing instant hot water on the water facility and avoiding heat loss caused by heat dissipation.
In a system without hot water recirculation, stagnant hot water will eventually lose heat and be discharged before fresh hot water is sent to the faucet.
The water circulation in the hot water recirculation system is achieved by a dedicated pump (3), which is usually installed in the return water pipeline. Due to the presence of dissolved oxygen and salts in tap water, pump components exposed to water must be made of corrosion-resistant materials.
The benefit of hot water circulation is to provide instant hot water on demand, reducing water waste,

COMFORT circulating pump is suitable for the following situations:
   Single loop system
   System with bypass (it is recommended to use a balance valve)
   Open system
   Pressure sealed system with or without mixing (tempering, anti scald) valve
   All types of water heaters with storage tanks.
