The hot water circulating pump article provides guidance and review about different types, qualities, durabilities, and prices. Hot water circulating pump is a pump used to circulate the hot water in a closed circuit. It is mainly used in domestic water systems to avoid the water cooling. The water in the hot water system gets cooled down when not in usage for a long time.
The cold water gets accumulated near the output of the domestic water supply system. When we turn the water heating system, the accumulated cold water comes through the discharge. Hot water flows only after the accumulated cold water is transferred. The domestic water supply system requires sufficient time before providing the hot water output.
The cold water accumulation also leads to the wastage of water. In order to avoid the time lag and water wastage, a pump can be used to circulate the hot water in the system. This pump circulates a small quantity of hot water in the system continuously and hot water is made available instantly on turning the system. The hot water flows without any delay or lag, and water wastage is avoided. These pumps are utmost required in places with minimal water resources.
Hot water circulating pump must be selected based on the following physical and environmental factors considering their need and application for effective and efficient functioning.
Type of pump – Circulating pump can be classified as two types as On-demand circulation pumps and Auto timed circulation pumps. On-demand circulating pumps are operated based on the requirement manually.
They operated only at the required time. Auto timed circulating pumps are controlled automatically by an aquastat and adjustable timer. The pump operates automatically by the control system without human intervention. Auto-timed pumps are expensive.
Water flow rate - the amount of hot water to be circulated in the system to provide instant hot water supply. The flow rate is expressed in terms of volume per unit time. It is measured in gallons per minute (GPM).
Return line – The return line is a piping system through which the cold water is returned to the system from the supply lines. Return lines are required only when the output supply is far away from the pump system. They are mostly not required in the small domestic and home applications.
Power – the amount of energy required for the efficient pump operation. The power source is electrical or DC powered by batteries or solar power. The pump is powered by the domestic water supply system itself.
Piping– Piping must be selected efficiently to avoid the heat loss during flow. They must be insulated effectively to prevent the heat dissipation and losses to the environment.
The main benefits of using a hot water circulation pump are as follows:
Hot water circulating pumps are mainly used in the homes for hot water supply. Hot water is required for various needs such as washing, bathing, etc. in our homes. They are also used for supply hot water in various industrial applications.
