Central heating pumps explained: Step 1: Water Intake. The water enters the central heating pump shortly after being heated by the central heating system. Step 2: Impellers. Central heating pumps are a type of centrifugal pumps. This means that they use impellers (think aeroplane engines) to pressurise water.
Why is my pump not working?
If you find that your pump is not working correctly, then one common reason is that air bubbles are trapped inside the pump. This stops the impellers working correctly and can cause an odd, random banging noise. Following manufacturer instructions, the pump bleed screw helps you bleed this air out of the system.
How does a heat pump work?
Similarly, a heat pump water heater captures heat from the air in your basement and uses it to heat water for your shower and sinks. The nature of the heat pump cycle means that heat pumps deliver useful heat far more efficiently than systems that generate new heat directly.
