boiler condensate drain

thanks for this. The manual states it has to go into the waste water system or else it has to be filtered through a device ( I can't remember what the device is called). Is this the same as the soil/sewage system?

The builder has said that because it is an old house (mid terrace in Dublin 8, 1950s build ) there is only one single discharge - effectively that waste water all goes into the same system as the rain water gutter. Does this make sense?

just found this in the manual for the boiler (Vitodens 050-w if you care to know...)

Condensate from gas combustion equipment up to 200 kW combustion output - Up to a rated heating output of 200 kW, the condensate from a gas condensing boiler can generally be introduced into the public waste water system without prior neutralisation.

Thanks but actually there is very little in that doc about what to do with condensate (apart from it should be drained) but the document does refer to "Heating and Domestic Hot Water Systems - Achieving compliance with Part L 2008" which had lots of helpful info, in particular this line:

Connection to external drain point

If the condensate drain cannot be connected to an internal drain then direct connection to an external gully or rainwater hopper can be considered. A rainwater hopper must be connected to a combined system ie sewer carries both rainwater and foul water. The open end of the pipe should be terminated in the gully or rainwater hopper below the grid level but above the water level.

Which brings me back to my original question - how do I know if the sewer system is a combined system? I guess I'll ask Irish Water.
