The primary heating and circulating pumps are the forefront of any commercial heating system and if they are not maintained the system will never work correctly and if they fail it wont work at all.

This is something that we focus on and on every planned preventive maintenance visit were appropriate we will always change over the pump duties on twin head pumps to spread the work load between them. This stops the spare pumps seizing up for long periods of not being used. If this is not done regularly you could find that when your main pump fails when you change over the pump duties the spare one will also fail causing complete loss of heating and hot water.

We can repair existing  pumps that are not working or install new pumps depending on the clients wishes.

Planned Preventive Maintenance (PPM)

PPM is imperative in the smooth operation of a commercial plant room and it saves £1000’s to have this done regularly it dramatically reduces the chances of plant equipment failing as you can see what equipment has deteriorated and address it accordingly.

If PPM’s are not completed regularly it is quite common that when a breakdown occurs there are multiple reasons due to different equipment failing at once causing costly repairs. CGE Southern offer PPM plans at very competitive rates.
