Central Heating

When a demand is made for heating by the system controls (i.e. a programmer or room thermostat). A pump will energise circulating primary water around the heating system and the burner, after a few seconds, will light. The heat output from the appliance in this mode has been factory set to give maximum output or as reset by your installer. The appliance will operate as necessary to maintain the temperature of the radiators at the level set by the adjustment of the boiler Temperature Control Knob. (See Fig. 1.)

If the system no longer requires output to maintain the desired room temperature, the burner will extinguish. The pump and fan will continue to run for a short period to dissipate the residual heat from the appliance and then switch off.

The appliance will supply heat to the central heating system as required.

Hot Water

The appliance operates to supply only domestic hot water when the heating temperature mode is fully anti-clockwise, at the 0 position or the timer is programmed to OFF mode.

MAINTAINING YOUR APPLIANCE

Your new Worcester boiler represents a long-term investment in a reliable, high quality product.

In order to realise its maximum working life, and to ensure it continues to operate at peak efficiency and performance, it is essential that your boiler receives regular, competent servicing and annual maintenance checks beyond the initial 12 month guarantee period.

Regular service contracts can be arranged with your installer
