School heating systems need to stay reliable, especially during term time when disruption has to be kept to an absolute minimum. This recent radiator change at a school in Oxford involved replacing a faulty radiator using a pipe freezing technique, allowing the work to be completed without draining down the entire heating system.
Alliance CFM carried out the work as part of a wider focus on efficient, low disruption school plumbing in Oxford, supporting safe and practical maintenance within an active educational environment.
Radiator Replacement Without Draining the System
In traditional radiator replacement work, the full heating system often needs to be drained down. In a busy school setting, that can lead to unnecessary downtime and disruption across multiple areas of the building. To avoid this, a freeze machine was used to isolate the pipework locally. This created a temporary ice plug inside the pipe, allowing the radiator to be safely removed and replaced without affecting the rest of the system.
Minimising Disruption in a Live School Environment
Working in an occupied school requires careful planning and a controlled approach. The freeze method allowed the radiator change to be completed quickly and cleanly, without shutting down heating across the wider system. This meant classrooms and communal areas could continue operating as normal, with minimal interruption to the school day. The work was scheduled and carried out with close coordination to suit site requirements.
Installing the New Radiator and System Checks
Once the old radiator was removed, the new unit was installed and connected to the existing pipework. The frozen section was then safely released, allowing normal system circulation to resume. The system was carefully checked for leaks, pressure stability and correct heat distribution. The new radiator was left operating as expected, restoring consistent heating to the affected area.

Frequently Asked Questions
What is a pipe freeze machine used for?
It temporarily freezes water inside a pipe to create a solid blockage, allowing work to be carried out without draining the system.
Why use freezing instead of draining the system?
It reduces disruption, saves time and avoids shutting down large sections of a heating system.
Is pipe freezing safe in schools?
Yes, when carried out by trained engineers using the correct equipment and procedures.
Can radiators be changed during term time?
Yes, using methods like pipe freezing allows work to be done with minimal disruption.
Do you provide school plumbing services in Oxford?
Yes, Alliance CFM provides plumbing and heating services for schools and educational buildings across Oxford.
How long does a radiator change take using freezing?
Most individual radiator replacements can be completed within a short timeframe, depending on access and system conditions.
