Underfloor Heating Repairs in Harrow & Ruislip
We repair all types of underfloor heating issues commonly found in homes across Harrow, Ruislip, Eastcote, Pinner, North Harrow, Ruislip Manor, and the surrounding areas.
✅ Airlocks within circuits: Airlocks can form within individual loops of the underfloor heating system, leading to cold spots and uneven heating. We identify and remove airlocks from these loops to restore proper water flow and system efficiency.
✅ Low flow rates or pressure problems: Low flow or pressure can result from blockages or imbalances in the system, including issues with return lines and return valves. We diagnose and repair faults in return lines and adjust or replace faulty return valves to ensure optimal circulation and pressure throughout all heating zones.
Common faults we fix:
• Underfloor heating is not heating up at all.
• Cold zones or uneven heat distribution
• Faulty or stuck actuators
• Pump or blending valve issues
• Airlocks within circuits
• Manifold leaks or failing components
• Wiring centre or thermostat faults
• Low flow rates or pressure problems
Our engineers quickly diagnose the issue using specialist tools and restore your underfloor heating to a complete working order.
Underfloor Heating Manifold Repair & Servicing
The manifold is the heart of your underfloor heating system, responsible for distributing hot water from the heat source to different zones throughout your home. If it isn't working correctly, the whole system becomes inefficient.
Regular servicing and correct underfloor heating installation are essential to ensure optimal performance. Proper underfloor heating installation and manifold setup are crucial for system efficiency and longevity.
Our manifold service includes:
• Full visual inspection for leaks, corrosion, and wear
• Pump performance check and cleaning, ensuring the pump is correctly installed
• Actuator testing and replacement (if required)
• Blending valve temperature calibration
• System flushing & bleeding to remove trapped air, including filling the system from the mains water supply for proper pressure testing and air removal
• Check and reinstall end caps during pressure testing to prevent leaks and contamination.
• Flow meter inspection and circuit balancing
• Checking and tightening all connections, making sure all pipes and fittings are securely connected
A properly serviced manifold ensures even heating, lower energy use, and a longer system lifespan.
Top Tips for Homeowners
Keeping your underfloor heating system in top condition doesn't have to be complicated. Here are our expert tips to help you get the most from your underfloor heating, whether you have a wet underfloor heating system or an electric underfloor heating system:
• Schedule Regular Maintenance: Routine checks are essential for optimal performance. Monitor your system pressure with a pressure gauge, and keep an eye on flow meters to ensure your heating system is working efficiently. Early detection of issues can prevent costly underfloor heating repairs down the line.
• Set the Correct Temperature: For most underfloor heating systems, the ideal flow temperature is between 35-45°C. This ensures comfortable warmth without wasting energy. If you're unsure, consult your thermostat or ask our underfloor heating specialists for advice.
• Check Compatibility with Heat Sources: If you're using a heat pump or installing a new boiler, make sure it's compatible with your underfloor heating manifold and can deliver the correct flow temperature and working pressure. A mixing valve may be needed with a combi boiler to maintain the proper water temperature.
• Ensure Proper Manifold Installation: The underfloor heating manifold is crucial for even heat distribution. Make sure it's installed with the correct flow and return ports, and that all connections are secure. This helps prevent cold spots and ensures warm water circulates efficiently.
• Consider Zoning and Controls: Divide your home into heating zones for better control and efficiency. Installing a two-port valve for each zone and a reliable wiring centre makes it easier to manage temperatures in different rooms and allows for future servicing.
• Opt for Professional Installation: Whether you're choosing wet or electric underfloor heating, professional installation is highly recommended. Proper plumbing, pressure testing, and manifold installation ensure your system works efficiently from day one.
• Monitor for Leaks and Air Bubbles: Regularly inspect your system for leaks, especially around the manifold, pipes, and end caps. Bleed the system to remove air bubbles, which can cause cold spots and reduce efficiency.
• Maintain Accessibility: When installing or upgrading your underfloor heating, ensure the manifold, pump, and valves are easily accessible for future servicing. This makes maintenance quicker and less disruptive.
• Insulate Pipes and Floors: Good insulation beneath the finished floor level and around pipes helps retain heat, improving energy efficiency and reducing running costs.
• Use the Right Equipment: Always use a suitable hose to fill the system, and check that the flow bar, return bar, and return manifold are correctly connected. This helps maintain correct flow rates and system pressure.
• Adjust for Room Requirements: Each room may have different heating needs. Use flow meters and thermostats to fine-tune flow rates and temperatures for each zone, ensuring every space is comfortable.
• Plan for the Future: Think ahead about future servicing and potential upgrades. Keeping installation diagrams and manuals handy can save time and hassle if repairs or adjustments are needed.
By following these top tips, you'll help your underfloor heating system work efficiently, avoid common problems, and enjoy a warm, comfortable home all year round. For any concerns or to book a professional check-up, our underfloor heating specialists in Harrow and Ruislip are always here to help.
