Central Heating pumps help ensure the heat is distributed evenly throughout your home
The heart of your heating system
Being too cold or too warm can affect how we enjoy our homes. A properly adjusted heating system can make a significant contribution to heating comfort. Did you know that heating systems rely on a circulation pump to make them work? In older properties, the central heating pump may have been installed many years ago and, depending on the model, age and condition, it could be costing more than your old washing machine to run, this is because the pump’s electricity consumption is one of several factors that influence a heating system’s running energy costs.
A modern cental heating pump can not only help to reduce the heating system’s electricity consumption – and thus your electricity bills – but it can also ensure the right level of comfort in your home by ensuring even heat distribution throughout the heating system. Your local can assess the efficiency of your existing pump and its operation based on technical data and measurements.

How does a central heating pump work?
The central heating system is designed to heat multiple rooms simultaneously using a heat source located either within one of the heated rooms or in an external location. Regardless of the heat emitters used, such as radiators or underfloor heating, the liquid central heating system relies on the circulation of the heating medium along the boiler-radiator route. This circulation is usually forced and carried out by a central heating pump. But what exactly is it? And how does it work
Heart of the heating system: The pump
The heating pump is a crucial component of the heating system, as it ensures that the hot water from the boiler is transported via the heating supply pipes to the radiators in the individual rooms. If there is no circulation or insufficient circulation from a pump, heat distribution within the heating circuit may be impaired. The pump creates a pressure difference within the system and moves the water through the pipework. A correctly sized heating pump and hydraulic balancing can help to ensure a more even distribution of the heating water.
Choosing the right heating pump is of immense importance. It must meet specific parameters to meet the system's requirements. An oversized or poorly regulated pump may – depending on the heating system and operating mode – result in higher electricity consumption
Different types of heating pumps
Over the decades, the technology, operation, and efficiency of heating pumps have significantly changed.
Uncontrolled pumps offer no option to adjust power or speed. Their performance is therefore generally too high, and they are often oversized for the heating system in which they are installed. Without demand-based control, the pump operates at the set power level throughout its running times, often even outside the heating season. As a result, they can consume more electricity than demand-controlled models when performing a comparable hydraulic task.
Electronically controlled heating pumps operate according to the thermostat settings of the radiators. They adjust their power consumption electronically and independently based on the thermostat settings and outside temperature.
High-efficiency pumps automatically adjust their speed and power to the current heating demand and are continuously adjustable. The pump can be controlled on an as-needed basis; the actual operating times are determined by the system control system. Under defined and comparable operating conditions, demand-controlled models may consume less electricity than their non-controlled predecessors. This not only saves energy but also potentially extends the pump's lifespan – depending on the specific model and the relevant operating and maintenance conditions.

When should I call a professional for help with my central heating?
If you have followed the simple steps above and cannot activate your heating system you will need to call a qualified plumbing and heating installer who will be able to identify why your central heating system is not working.
How can I prevent central heating problems in the future?
Make sure that your central heating system is checked annually by a qualified plumbing and heating installer. This includes checking that your boiler and any components on the system, including your central heating pump, are working correctly.
Why is my central heating pump so noisy?
Can I replace a central heating pump myself?
When is it recommended to replace the heating pump?
Replacing an old central heating pump with a new model can help to reduce your energy bills. Older pumps often still operate without regulation, i.e. they do not adjust their output and are therefore inefficient. It is therefore advisable to replace an outdated heating pump with a modern version that meets the latest standards. Please consult with your professional installer for advice.
