Condensate Pump For a Boiler


Condensate pumps gather and distribute heated water and liquid resulting from condensation in heating systems.

An illustrative scenario highlighting the necessity of a condensate pump arises when a boiler is situated in a basement. This usually occurs when the boiler is in a basement or far from the drainage system. A condensate pump for a boiler will facilitate convenient access because gravity will not propel the water to a ground-level drainage system.

How does a condensate pump for a boiler work?

When a boiler operates, it produces not only heat and steam. When cooled, this is converted back into water droplets known as condensate. This condensate is acidic and must be disposed of through the property’s drainage system. The challenge lies in efficiently removing this condensate from the system, as its accumulation can lead to corrosion and decreased boiler efficiency.

Condensate pumps, categorised as centrifugal pumps, are designed to address this challenge. These pumps safely and efficiently remove condensate from the boiler and transport it to a designated drain or external disposal system. By doing so, they prevent corrosion within the boiler and ensure its optimal functioning.

Whether it’s a commercial or residential property, ensuring excess water from condensation is drained effectively is a must to help the heating system operate efficiently.

The design of a Condensate Pump

Manufactured for intermittent operation, a condensate pump has a collection tank to capture the accumulated condensed liquid. A float switch activates the pump once the liquid attains a predetermined level. This mechanism efficiently pumps the condensate until the liquid level allows for additional collection.

In specific pumps, a two-stage switch is incorporated. The initial stage is activated when the liquid reaches a specified level, setting the pump into motion. A second stage is initiated in the event of continued liquid rise, signalling a potential pump failure or discharge obstruction. This stage may involve shutting off the pump or activating an alarm. The entire system operates seamlessly and autonomously.

Key Features of Condensate Pumps

  1. Automatic Operation: Most modern condensate pumps operate automatically, triggered by sensors that detect the presence of condensate. This automation ensures a seamless and continuous removal of condensate without manual intervention.
  2. Efficient Discharge: Condensate pumps are engineered to discharge condensate at a rate that matches the boiler’s production, maintaining a balanced and efficient system.
  3. Corrosion Resistance: Given the corrosive nature of condensate, these pumps are constructed with materials resistant to corrosion, ensuring longevity and reliability.
  4. Quiet Operation: Advanced condensate pumps are designed for quiet operation, minimising noise in the boiler room and promoting a comfortable working environment.
  5. Compact Design: The compact size of condensate pumps allows for easy integration into various boiler systems, making them a versatile solution for different applications.

It is important to note that the regulations covering condensing boilers in UK properties state that all gas-fired boilers fitted after 1st April 2005 must have a SEDBUK efficiency rating of either A or B. All oil-fired boilers fitted after 2007 must be condensing boilers.

Importance of a Condensate Pump for a Boiler Working Efficiently

Efficient condensate removal is not merely a matter of convenience; it directly impacts the overall efficiency and lifespan of the boiler system. Corrosion from condensate accumulation can lead to costly repairs and premature equipment failure. Efficiently managing a condensate pump for a boiler will have a positive impact on energy savings and reduce the environmental footprint.

It is vital to note that when installing a condensing boiler, care must be taken to remove them correctly because boilers are typically installed far from any evacuation points.

Choosing the Right Condensate Pump for your boiler

When selecting a condensate pump, it is crucial to consider factors such as the boiler’s size, the volume of condensate produced, and the application’s specific requirements. Consulting our qualified HVAC professionals can ensure the correct pump is chosen to complement the boiler system, maximising efficiency and minimising maintenance issues.

Customers commonly ask if the PRV Pipe can go into the pump, and the answer is yes; however, the PRV pipe can pass water at 100°C in boiler fault conditions. This means a condensate pump is needed that can take higher temperatures.

Key Features:

  • Flow rate – 600 l/h
  • Tank Capacity – 2.65 litres
  • Max Condensate Temperature – 90°C for 5 mins
  • Dimensions – H 183 x W 258 x D 165 mm
