About GEMS

A clearer condition.
A better informed response.

Commercial hot-water monitoring that helps operations and maintenance teams work from the same picture.

Guardian Element Monitor

Know what your cylinder is doing.

GEMS brings water temperature, heating demand and measured electrical load together. Your team gets a visual view of each monitored cylinder, with individual elements and supporting history.

That context matters. A request for heat is not the same as an element delivering heat. Seeing both helps you recognise a condition that deserves attention.

What you can see

  • Water temperatureThe available reading and its history.
  • Individual heating elementsDemand and measured electrical condition.
  • Site visibilityYour assigned locations in one portal.
  • Reading freshnessA clear distinction between current and unavailable information.

Maintenance with context

Support a more proactive approach.

GEMS supports predictive maintenance by helping your team recognise changing performance and anticipate risks. Current conditions and history provide the context for proactive and planned maintenance decisions.

PREDICTIVE APPROACH

Recognise changing performance.

Review temperature trends and element behaviour to understand changes that may need investigation, rather than relying on a single snapshot.

PROACTIVE MAINTENANCE

Investigate earlier.

Where an individual element is highlighted for attention, your team can assess the issue while another element may still be supplying heat.

PLANNED MAINTENANCE

Prepare the right response.

Use site conditions and history to inform a visit, agree priorities and reduce avoidable disruption to day-to-day operations.

“Is this element being asked to heat — and is it drawing the load we expect?”

A useful question. A clearer basis for action.

Make maintenance a better informed decision.
