Planned maintenance keeps your system working

Reactive call outs cost more.

They also happen at the worst time.

Planned maintenance helps you:

  • Maintain hot water delivery consistency
  • Reduce energy consumption drift
  • Identify failing components early
  • Protect warranties and compliance
  • Reduce emergency downtime
If your site has peak demand periods, scheduled servicing matters.

What happens during service visits

  • System inspection and condition report
  • Performance checks, temperatures, pressures, and flow rates
  • Heat pump servicing and fault diagnosis
  • Pump and valve checks
  • Sensor and controller parameter inspection
  • Leak checks and safety checks
  • Solar collector inspection and mounting checks
  • Heat accumulator inspection and insulation checks
  • Cleaning of entire plantroom/system
  • Commissioning checks after repairs or upgrades

Breakdown Support When You Need It

If your system is down, we can assist with:
  • Diagnosis and repair
  • Component replacement
  • Control adjustments
  • Heat pump fault resolution
  • Plant room safety and recovery
  • Temporary operational stabilisation
If the system is not originally installed by Solar Heat, we start with an assessment to confirm condition and compatibility.

Improve Efficiency Without Replacing Everything

Common upgrades include:
  • Hybrid conversions
  • Heat accumulator integration
  • Pump and valve upgrades
  • Improved insulation and heat loss reduction
  • PV integration for plant offset
This is where many sites get immediate cost savings.

Maintenance and Service FAQs

How often should a heat pump system be serviced?
Most commercial systems need scheduled servicing at least twice per year, more often for high demand sites.
Do you service systems not installed by Solar Heat Exchangers?
Yes, subject to an initial assessment and confirmation that parts and access are viable.
Do you offer preventative maintenance contracts?
Yes. Contracts reduce downtime risk and provide predictable service scheduling.
Can you help improve system performance if energy costs are rising?
Yes. We can evaluate control settings, staging, storage, and operational patterns to reduce consumption.
