Cranbrook's modern new build homes offer exceptional energy efficiency and cutting-edge plumbing systems, but they can also present unique challenges not found in older properties. From underfloor heating issues to smart home water systems, understanding these modern plumbing setups is essential for efficient troubleshooting and maintenance.
Common Underfloor Heating Problems in Cranbrook Homes
Many new builds in Cranbrook feature underfloor heating systems that provide efficient, comfortable warmth. However, these systems can develop issues that require specialist knowledge:
Cold Spots and Uneven Heating
Often caused by air trapped in the system or flow issues. We use specialized equipment to identify and resolve these without damaging your floor finishes.
System Pressure Loss
New build underfloor systems can experience pressure drops due to microscopic leaks or air ingress. Our diagnostic approach pinpoints issues without invasive work.
Control System Faults
Modern digital controls sometimes develop software or sensor issues. We're experienced with all major systems installed in Cranbrook properties.
Manifold Balance Issues
Incorrect balancing at the manifold can cause some zones to overheat while others remain cool. We precisely calibrate your system for optimal performance.
Case Study: Cranbrook Underfloor Heating Fix
A Cranbrook homeowner contacted us when their 3-year-old property's underfloor heating system began performing poorly, with certain rooms remaining cold despite the thermostat settings. The developer had been unable to resolve the issue. Our diagnostic process revealed a combination of air locks and an incorrectly commissioned manifold. After a thorough system flush, proper balancing, and control recalibration, the system now delivers consistent warmth throughout the property, with the homeowner reporting a 15% reduction in heating costs.
Smart Home Water Systems
Cranbrook's newer properties often feature integrated smart water systems. While these offer convenience and efficiency, they require specialized knowledge:
- Water Leak Detection Systems: Smart leak detectors can sometimes trigger false alarms or fail to communicate properly with home hubs. We diagnose and recalibrate these systems to ensure reliable operation.
- Smart Water Meters: Integration issues between meters and monitoring apps are common. We ensure proper data flow and accurate consumption readings.
- Automated Shut-Off Valves: These critical safety devices sometimes fail to respond to leak signals or app controls. We test, repair, and replace these systems to protect your home.
- Smart Water Heater Controls: Digital control systems for water heating sometimes develop software issues or sensor failures. We troubleshoot and resolve these complex problems.

Combi Boiler Pressure Issues in New Builds
Combination boilers are standard in most Cranbrook properties, but they often develop pressure-related issues that can affect performance:
Symptom | Likely Cause | Our Solution |
---|---|---|
Pressure drops regularly | Minor system leak or PRV issue | Thermal imaging leak detection and PRV replacement |
Pressure rises too high | Expansion vessel failure | Vessel replacement or recharging |
Pressure correct but poor hot water | Diverter valve issues | Valve repair or replacement |
Fluctuating pressure | System design faults | System modification and balancing |
