Why Regular Servicing of Underfloor Heating is Essential

During colder months, it becomes imperative to ensure that your underfloor heating (UFH) system is prepared to provide consistent and efficient warmth. While underfloor heating is celebrated for its low maintenance needs, asking “does underfloor heating need servicing?” reveals a common misconception. 

Regular servicing is not just recommended by the experts; it’s necessary to maintain optimal function and efficiency. Servicing underfloor heating systems proactively before the winter ensures they run smoothly, avoiding the disappointment and discomfort of malfunctions during the cold months.

Common Issues Identified by Regular Servicing

Regular underfloor heating maintenance can identify several potential issues that might compromise your system’s efficiency and functionality. 

For instance, trapped air in the heating pipes can create cold spots, while unbalanced flow rates and blockages can lead to uneven heating and increased energy costs. Regular checks can also prevent wiring issues and malfunctioning pumps, which are critical for maintaining a consistent heat output. 

By addressing these issues early, you not only ensure comfortable living conditions but also avoid costly emergency repairs.

Benefits of Regular Underfloor Heating Servicing

The benefits of regularly servicing underfloor heating systems extend beyond simple operational efficiency. 

First and foremost, it ensures the longevity of your heating system, keeping it in prime condition and reducing the likelihood of breakdowns. 

This regular attention not only saves money on potential future repairs but also improves the overall safety of the system. 

A well-maintained UFH system operates more efficiently, which can significantly reduce heating bills. Furthermore, regular maintenance provides peace of mind, knowing that your home will remain warm and cosy throughout the winter.

How often does underfloor heating need servicing? 

It is advisable to schedule a check-up annually. 

Ideally, a service should be conducted a year after installation and then annually thereafter. This time frame ensures that any potential issues are caught early and addressed promptly, maintaining the system’s efficiency and reliability.

How to Service Underfloor Heating Systems

Servicing underfloor heating does not have to be done frequently, but it is crucial to ensure the system operates efficiently and effectively. Below, we’ll explore the steps involved in maintaining a water underfloor heating system, ensuring it delivers consistent, reliable heat.

Initial System Check

• System Pressure Check: Begin by examining the system’s pressure using the gauge located on the flow bar of the manifold. Normal operating pressures typically range between 1-2 bar. This initial check helps ensure the system is not operating under stress or below efficiency levels.
• Water Quality Inspection: Check the colour of the water within the flow metres. Some discoloration over time is normal; however, if you notice a dark brown hue or excessive dirtiness, it may indicate that the system requires flushing and reapplication of a chemical inhibitor to prevent corrosion and buildup.

Air and Water Flow Management

• Air Vent Inspection and Bleeding: Air trapped in the wet underfloor heating system can significantly reduce its efficiency. Inspect the air vents on the top bar of the manifold to remove any excess air. Systems with an automatic air vent may not require manual bleeding, but it’s good to check these occasionally to ensure they are functioning properly.
• Thermostat and Heating Activation Check: Ensure the underfloor heating system activates correctly by increasing the thermostat setting to trigger the boiler, pump, and valves. This test should be performed independently for each zone to verify that all components are responding to thermostat commands without interference from other heat sources.
• Functional Testing of Individual Loops: Repeat the thermostat activation test for each loop or zone within the system. Conduct these tests with the rest of the system off to ensure that each area can independently call for heat and operate as expected.

Maintaining the System 

• Thermostat Programming Verification: For homes with digital or programmable smart thermostats, verify that the settings match the homeowners’ preferences and are programmed for efficient heating patterns. This ensures the system is not only functional but also customised to the specific living conditions and requirements of the household.
• Feedback Collection: Engage with the homeowner to inquire about any concerns or questions they might have regarding the underfloor heating system. This step is crucial for identifying hidden issues that may not be apparent during routine checks.

Maintenance Explanations:

• Bleeding the System: When we discuss the term ‘bleeding’ this refers to clearing out the system of trapped air. While not a frequent necessity, bleeding the underfloor heating system helps remove trapped air that can impact efficient heat distribution. If you’re unsure about how to bleed the system safely, it’s advisable to consult with a professional.
• Flushing the System: Similar to bleeding, flushing is vital for removing buildup within the pipes. This process involves circulating high-pressure water mixed with anti-corrosive agents through the system to clear out sludge and rust, ensuring optimal performance and prolonging the system’s lifespan.

Thermostat Checks:

• Check and Reset: Regularly check your thermostat for proper operation. If issues arise, such as the heating not responding or the system remaining on, try resetting the thermostat according to the manufacturer’s instructions.
• Battery and Wiring Checks: For wireless or battery-operated thermostats, ensure that the batteries are functioning correctly. Check all wiring connections for integrity, as loose or damaged wires can lead to system malfunctions.

Key Installation Tips on Why Does Underfloor Heating Need Servicing?

Installing underfloor heating can be a rewarding DIY project that improves home comfort significantly. However, to ensure it functions effectively, certain guidelines should be followed during the installation process.

• Read the Instructions: Before you start installing your underfloor heating system, carefully read the manufacturer’s manual. Every system can have unique requirements based on its type, make, and model. Overlooking this step can lead to avoidable mistakes that may affect the system’s functionality. Understand more with these common underfloor heating mistakes.
• Conduct Pre-Installation Testing: For electric underfloor heating, use a multimeter to measure the resistance and ensure there are no breaks or faults in the heating elements. It’s recommended to turn the system on for a brief period (no longer than 10 minutes) to check if it heats up properly.
• Rehearse the Installation: Familiarise yourself with the installation process by walking through the steps as outlined in the instruction manual. Check if you have all the necessary tools and understand the setup fully before beginning the actual installation. This rehearsal can prevent mid-process surprises and delays.
• Continuous Testing During Installation: As you install, continue to test components. This includes checking connections and ensuring each section of the heating system functions as expected as soon as it’s laid out and before the final flooring is applied. This proactive approach helps in identifying and rectifying issues early.
• Thermostat Use: To maximise energy efficiency, use a smart thermostat with your underfloor heating system. Smart thermostats allow you to adjust temperatures remotely and set heating schedules that align with your daily routines, potentially saving up to 25% on energy bills.
• Maintain Low, Consistent Heat: Instead of turning the heating off, maintain a low baseline temperature. This strategy prevents the system from the lengthy warm-up times and ensures your space remains at a comfortable temperature more consistently. Adjust the heat according to different times of the day or activity levels in the home for optimal comfort and efficiency.
