Condensate disposal

Condensate disposal

All condensing boilers generate condensate discharge which needs to be piped away from the appliance in a plastic pipe.

The amount of condensate generated depends on the efficiency and operating status of the appliance. Depending on operating temperatures, the appliance will condense in both heating and hot water modes and can generate up to 2.5 litres of condensate an hour.

Never terminate or discharge into any open source, including: sink, bath, shower, bidet, toilet etc.

Note: any external condensate pipework should be protected with weather resistant insulation to help prevent freezing or be run in 32mm plastic waste pipe.

The condensate connection on Worcester appliances is in 21.5mm polypropylene. The pipe should be extended and run away from the appliance with a constant fall of 3º or 50mm in every metre.

The condensate trap is supplied with the kitchen model for installation externally from the appliance cabinet. This trap is located within the cabinet of the external models. The condensate pipe can terminate into any one of four areas:

External condensate pipework

The Greenstar Heatslave is supplied with a condensate trap that needs to be connected outside of the boiler cabinet on kitchen models but as close as possible to the appliance. The condensate trap is located within the cabinet of external models.

Where the condensate pipe has to be externally run, the following should be considered:

• The pipe run should take the shortest practical route.
• The pipework should be protected with weather resistant insulation to help prevent freezing or be run in 32mm plastic waste pipe.
• The pipe should terminate as close as possible to the ground or drain, whilst still allowing the condensate to safely disperse. This will minimise the possibility of wind blowing up the pipe.
• The pipework should be installed with the minimum of horizontal runs and with a downward slope of at least 3º or 50mm in every metre.
• The maximum external condensate run is 3 metres.
