Central heater pump is used to circulate hot water within houses. These small pumps are installed within the central heater systems in the house.
Hot water is an undeniable necessity that can never be considered a luxury. Lately, there’s been a general tendency towards using central boilers, as they use less power and give better inner appearance to the places. Nevertheless, central boilers need central boiler circulating pumps.
The central boilers’ pump makes sure that hot water continues to flow and circulates in the pipes all the time. So, if the tap is opened, hot water flows directly without needing to wait.
Not all types of water pumps can endure the high temperature of the boiling water, thus specific types of pumps are available for the central heating systems. The pump pulls the cold water in the pipes and replaces it with hot water continuously. So, with opening the tap the heated water flows instantly even at peak hours.
The pump has a small size, and it’s usually loaded near the central heater.
It consists of 5 parts:
The latter two parts are seldom used and if needed, it is done by the hands of an expert.
There are plenty of options in the market when seeking a central heater pump; however, Al Lira Al Zahabiya Co. provides the best, the Rainbow brand.
The pump is of the code SR25/6G-180 mm and it is made of rust-resistant metals. The pump weighs 2.5 kilograms, has dimensions of 18×13×8.5 cm., and a port-to-port distance of 180 mm. These dimensions clarify how small the pump is, thus it can be loaded anywhere within the building without any problem.
The unit doesn’t need batteries as it works with electricity; yet, it rationalizes the consumption.
The price of this pump is 550 Qatari Riyal with installation and wiring included. Al Lira Al Zahabya Co. provides a one year guarantee upon the pump.
About the specifications, capacity, and efficiency of Rainbow’s centra; heating pump, they are as follow:
The central heater pump has different characteristics resulting in the presence of a wealth of styles that fit the different needs.
Firstly, they differ in the alloy of manufacture, thus their endurance to high temperatures varies. Secondly, they differ in the power of the motor which leads to the difference in the head maximum. Thirdly, the difference within the source of power. Some pumps use batteries while others -which are the most common- use electricity. Fourthly, some pumps are single-headed and others are double-headed.
Finally, central heater pump types vary in the speed of water pumping. Some are single-speed or double-speed circulators and others are three-speed circulators. This type needs manual adjustment of the desired speed. The more modern types are highly efficient auto-adjusting circulators that don’t need any intervention.
During the pump’s action, it produces only a low humming sound due to the low noise property it owns. Aside from that, it is normal for the pump to become touchably warm and not cause any harm when in action.
If the pump starts producing loud unusual noise or started being too hot accompanied by lack of efficiency and delayed hot water flow through the pipes to the taps, this means there is an air-lock inside the pump.
An air-lock interferes with the smooth water flow alongside causing water to bang the different parts of the water system. This air-lock has to be released; otherwise, the damage to the components or the pump can be permanent so they will have to be replaced.
If the problem persists or if there is no desire to deal with such procedures, maintenance is always there for such circumstances.
Another reason that may result in lowering the efficiency of the pump is the dirt accumulating inside the central boiler. If the problem remains after bleeding the pump, both the boiler and the reservoir must be cleaned by the hands of the professionals.
As the Rainbow brand pumps from Al Lira Al Zahabya Co. excel at electricity rationalizing consumption, they also are excellent at water rationalizing consumption. They accomplish this quality by the presence of the return line within the water system of the building.
Two water lines emerge from the reservoir, the first extends directly to the taps and it is responsible for the cold water flow while the other reaches the boiler. After heating the water to the required temperature, the pump -which is considered the heart of the heating system and its directing- pulls the water from the boiler through the pipes and to the taps through the hot outlets.
The unused hot/warm water alongside the cold water from the pipes continue to flow through the return line until they pour back into the central reservoir. The central heater pump creates a negative pressure at this side of the water circuit which helps the water to continue flowing quickly until reaching the central boiler again. This way, the pump accomplishes the continuous flow of the hot water as well as accomplishing water consumption rationalization through both the return line and avoiding the spilled cold water while waiting for the hot water to flow.
Yes, the pumps are very safe. They incorporate an overload switch for more safety. If the pump gets too hot, this switch cuts off the electricity from the pump.
Central heater water pumps are available in three sizes which are small, medium and large. The first two are suitable for houses while the third is a better fit for facilities such as hotels and hospitals.
No, the pump uses electricity at 240 volts and 50 Hz. So, it doesn’t need batteries.
If the cold water flows for a bit followed by the hot water, then it is the pump. But if the cold water continues to flow endlessly, then it is the central heaters.
