What it is

The Stuart SPU 130 Mini is a pressurisation unit manufactured by Stuart Turner. It is designed to maintain and top up pressure within a sealed heating system, replacing manual filling arrangements with automatic pressure control. The unit is listed within the boiler category of the manufacturer's range.

Signs this part needs replacing

  • System pressure falls repeatedly and does not hold after manual topping up
  • The unit runs continuously or cycles without bringing the system up to pressure
  • No pressure increase is seen at the system gauge when the unit operates
  • Water is found leaking from the unit body, connections or overflow
  • Fault or alarm indication is shown on the unit

Before you order

  • Check the existing unit's model number and confirm it matches the SPU 130 MINI
  • Confirm the system is a sealed system that the unit is intended to serve
  • Check the pipework connections and electrical supply arrangements of the existing installation against the replacement unit
  • Confirm any associated components in the pressurisation arrangement are serviceable before fitting
