Which circulator pump is good for you?

Hot water circulator pumps can be found nearly everywhere with a variety of manufacturers and options to choose from. Many of the earlier circulator pumps worked non-stop and were more expensive to operate because they were constantly using electricity.

How to size a circulator heating pump?

Fitting a circulating pump to your hot water system is not complicated, but you must know how to properly size the pump. Getting the largest pump might not be the right solution if you have a small hot water system, but one that is too small can cause a lot of problems in obtaining hot water from your system.

The misconception about pump head which 90% of people don’t know

The pump head is another way of expressing energy. Like common misconceptions, it is not another way of expressing pressure or the direct measurement of the height to which a pump can deliver the fluid.

The features of circulator pumps

Circulator pumps are also called circulating pumps, circulation pumps, which are commonly used to circulate clean liquids in a hydronic heating or cooling system.

What is the ErP directive and its effect on circulating pumps?

The Eco-Design of Energy Using Products (EuP) Directive is EU legislation requiring manufacturers to improve the lifecycle energy efficiency of their products, and reduce their overall environmental impact.

PWM – Remote Control On Circulator Pumps

PWM make it possible to control the pump in a remote distance through a digital cable transmitting digital signal. Pumps with PWM control are widely used in the gas boilers systems and heat pump systems.

What are the benefits of using high efficiency pumps?

High efficiency provide an 85% to 90% reduction of electrical consumption. Depending on what you pay per kilowatt hour, that electrical savings may translate into $3 to $5 per month during the heating season.

Wet rotor & dry rotor circulator pumps- what’s the difference?

Depending on the design, all the pumping units of the heating systems are divided into two types:
-Wet rotor circulator pump
-Dry rotor circulator pump

Open vented and closed loop heating system-which is better for you?

In general there are two types of system for accommodating thermal expansion, Open vented system and Sealed system (Closed loop).
-In an open vented system(open loop) an open tank at the highest point of the installation is used to store the expanded fluid.
-In a closed system (pressurised/sealed) an expansion vessel is used to store the expanded fluid.

Tips for choosing and using circulator pumps

The use of circulator pumps in heating systems saves up to 30% of the energy used to heat the coolant. When choosing a circulator pump, it is necessary to consider where the pump will be used in the heating system or hot water supply. The circulator pumps work continuously throughout the heating season, so they are faced with high demands: silent operation, low power consumption, simplicity and reliability.

How to avoid blocked circulator pump

If the circulator pump or system is filled up with water for the first time and the pump is stopped for a longer period of some weeks or months, it might happen that the pump is not able to start. There are two de-blocking systems. Circulator pumps usually feature one of them or both.

How to increase the water pressure in house

The problem of low water pressure is quite common in multi-storey buildings, where residents of the upper floors, due to the very low pressure in the plumbing system, often sit without water. A good way out of such an unpleasant situation is to install a booster pump to increase the pressure level.

Troubleshooting Tips for Circulator Pumps

Since a circulator pump is a moving part with rotors and impellers, it can fail or malfunction if one of those parts becomes excessively worn or damaged. The good news is that the circulator pump often gives off warning signs before it completely stops.

Save your money by adding a recirculation system and a thermal-expansion tank

How to put your hot-water system on an energy diet without sacrificing comfort? Here are the two strategies that will reduce your energy bills and your carbon footprint.

How to solve the problem of long wait for hot water

You must be familiar with the long wait for hot water: You turn on a hot-water faucet and have to wait a full two minutes for the hot water to arrive. Learn how to efficiently reduce your wait time for hot water.

Circulator Pump and Heat Pump System

A heat pump is an HVAC product that uses the heat of outside air, water or earth to efficiently heat your home in the winter and cool it in the summer. Circulator pump works like a heart of heat pump to circulate the water in the system and increase the system pressure.
