Heating System Troubleshooting & Initial Fault Checks
Infrared heating systems are designed for reliability and long service life. In the unlikely event that your system is not performing as expected, a small number of routine checks will resolve most issues quickly.
Before arranging a service visit, we recommend working through the guidance below.
These checks apply to both residential and commercial installations.
Step 1: Confirm Electrical Supply
Many apparent system “faults” are caused by interrupted power supply.
Please check:
Fused spurs supplying heaters
Contactors (where installed)
MCBs or RCBs in the electrical distribution board
Any local isolation switches
Ensure all relevant circuits are switched on and have not tripped.
If a breaker has tripped, reset it once. If it trips again immediately, discontinue use and contact a qualified electrician.
Step 2: Check Control System & Connectivity
If your system is operated via controls including Delta Dore systems (applies to systems with smart controls), confirm:
Internet connectivity is active
The control hub is powered on
The hub status indicator is showing normal operation (typically white on Tydom hubs)
The router is functioning correctly
The hub status indicator is showing normal operation (typically white on Tydom hubs)
Loss of internet connection or power interruption may require the system to be reset.
If your controls were commissioned by one of our installer partners or your electrical contractor, they will have been configured with baseline programming. A power cut can occasionally revert or interrupt settings.
Resetting to the original configuration often restores operation.
Step 3: Thermostat & Battery Checks
If using wireless thermostats:
Check battery levels
Replace batteries if low
Confirm the thermostat is calling for heat
Verify temperature settings are above current room temperature
Flat batteries are a common and easily resolved cause of non-operation.
Step 4: Recent Power Cuts
If the issue has occurred following a power outage:
Confirm all system components have powered back on
Check time and schedule settings to have powered back onack on
Reconfirm programmed heating periods
Verify hub connectivity has re-established
Most systems resume normal operation once connectivity and schedules are restored.
If the Issue Appears to Be Control-Related
If the system powers on but is not responding correctly to scheduling or app controls, the issue is typically control or programming related.
For Delta Dore systems, direct technical assistance may resolve the matter remotely and quickly.
Technical Support:
Remote support often resolves configuration issues without requiring site attendance.
If the Issue Appears to Be Heater-Related
If:
The heater is not warming
There is visible damage
The unit is not powering despite confirmed supply
There are unusual noises or behaviour
The unit may need to be returned for inspection.
Where the product is within its manufacturer warranty period:
The unit will be tested
If confirmed faulty, a replacement will be issued subject to availability
If no fault is found, the product will be returned and carriage charges may apply
We recommend confirming electrical supply via a qualified electrician before returning any product.
When a Call-Out Is Required
If the above checks do not resolve the issue, a site visit may be necessary.
Our service call-out policy includes:
A fixed call-out fee covering the first two hours
Agreed hourly rate thereafter if additional time is required
Clear guidance on warranty eligibility
Defined responsibility where installation issues are identified

Installer Responsibility & Warranty Considerations
Where a fault is identified as installation-related:
If installed by an ARC installer partner and within workmanship warranty, corrective action will be arranged without additional charge.
If installed by other electrical contractors, responsibility may rest with the original installer.
Manufacturer warranty applies only to confirmed product defects.
