Measuring Boiler Outputs
A Micronics Clamp-On Heat Meter has been temporarily installed onto boilers in order to confirm the peak outputs of each boiler.

Air Source Heat Pumps
An initial survey of the roof top heat pump systems has highlighted some significant problems.
- No way to understand current operation, without any feed into a monitoring (SCADA) system.
- No alarming
- No performance monitoring
- At least one of the main circulating pumps to the heat pumps has never been wired up, making operation of the heat pump impossible since installation.

Next Steps
- Obtain all relevant manufacturers instructions on heat pumps and fitted controls
- Upgrade controls with open control system and remote monitoring so that the heat pumps can be setup and controlled as required
- Recommission heat pumps using new system
- Monitor performance and setup alarm routes
