Freeze protection monitoring
Catch the freeze before the pipe cracks.
Most winter bursts start as a freeze in an unheated loft or exposed run. AQUAIOT places temperature sensors on the pipework most at risk and alerts you while the water is still solid, so you act before the thaw turns a frozen pipe into a flood.

Freezing is the winter cause of bursts.Water in an unheated loft or exposed run freezes, expands and cracks the pipe, then floods on the thaw, which is why bursts cluster in cold snaps.
Moisture alerts come too late.By the time a pad is wet the pipe has already failed, so a freeze warning has to read temperature, not water, to give you any lead time.
The bill arrives with the thaw.The average burst-pipe claim was around 7,500 pounds in 2024, and a frozen run that goes unnoticed turns into exactly that loss overnight.
Voids and lofts go unchecked.Exposed pipework in empty units, lofts and plant rooms is rarely visited in winter, so a freeze builds with no one near enough to notice.
The AQUAIOT SolutionRequest a Consultation
Watch the temperature, not just the water
By the time a moisture sensor is wet, a frozen pipe has already cracked and thawed. Freeze protection monitoring moves the warning earlier. AQUAIOT mounts temperature sensors on exposed and loft pipework, in plant rooms and on external runs, and alerts the duty holder as readings approach freezing, well before ice forms and expands. Pair it with auto-isolation valves and the supply can close ahead of the thaw, so a vulnerable run never becomes a burst.
Temperature sensing on the runs that fail. Sensors on exposed pipework, loft spaces, plant rooms and external runs read the cold long before ice forms, so the warning comes ahead of the crack.
Alerts as readings approach freezing. Thresholds trigger a role-based alert to the duty holder as temperatures drop toward zero, giving time to add heat, lag a run or isolate the supply.
Isolation ahead of the thaw. Where a run is high risk, an auto-isolation valve can close the supply before a thaw, so a frozen pipe that does crack has no water to release.

How It Works
Three steps from first drop to evidence
Step 01
Detect
AQUAIOT moisture, flow and freeze sensors are deployed at the points water escapes. Every reading is timestamped and logged to the cloud over secure cellular or LoRaWAN telemetry.
Step 02
Alert and isolate
When moisture is sensed or flow goes abnormal, AQUAIOT raises an immediate alert by SMS, email and app, and closes the auto-isolation valve so water is stopped before damage spreads.
Step 03
Record
Every reading, alert and isolation event is captured in exportable, timestamped logs that integrate with CAFM and BMS, so evidence for insurers is ready on demand.
Capabilities
Everything a leak detection programme needs
Purpose-built for estates, facilities and risk teams protecting buildings against escape of water across single or multiple sites.
Moisture sensing at the risk points
Point, rope and tray sensors detect water at first contact under appliances, in plant rooms, risers and tank rooms, before it spreads.
Inline flow analytics
Continuous flow monitoring on the incoming main learns normal use and flags the slow weep or continuous draw a manual check never sees.
Freeze protection
Temperature monitoring on exposed and loft pipework warns before a freeze leads to a burst, so action can be taken in time.
Automatic shut-off
Auto-isolation valves close the supply the moment a moisture or abnormal-flow threshold is crossed, with manual remote override for the duty holder.
Multi-channel alerts with escalation
SMS, email and app alerts with role-based routing, so the right person responds day or night, on a single site or across a portfolio.
Open integration, no lock-in
Connects to BMS, CAFM and SCADA via RS485/Modbus or REST API, with audit-ready exportable records for insurers and owners.

Questions & Answers
Common questions
What does freeze protection monitoring do?
Temperature sensors on exposed and loft pipework, plant rooms and external runs read the cold and alert the duty holder as readings approach freezing, before ice forms and cracks the pipe.
Why monitor temperature instead of moisture?
A moisture sensor only triggers once a frozen pipe has already cracked and thawed. Reading temperature gives a warning while the water is still solid, so there is time to act.
What can we do once we get a freeze alert?
Add heat, lag the run or send someone to the location, and where the run is high risk an auto-isolation valve can close the supply before the thaw releases any water.
Where should the sensors go?
On the pipework most at risk: exposed runs, loft spaces, unheated plant rooms and external pipe, especially in empty units and lofts that are rarely visited in winter.
Is installation disruptive?
No. Temperature sensors are non-invasive and retrofit-friendly, clipped to the pipework without cutting into it or shutting the building down.
