Hi
I am having my kitchen revamped and have removed the sink and waste pipes.

However the condensate drain pipe was connected to the waste pipe so I therfore temporarily dropped the condensate drain into a bucket.

I have since turned on the boiler so my wife could take a shower and noticed water vapour/steam coming from the condensate drain pipe...

Is this normal or a problem with the boiler which is an Isar Ideal HE24.

Many thanks in advance for any repies.

Mr Fog
 
Don't run the boiler into a bucket with the isar series the condense isn't trapped so needs a trap inline, normally just below the boiler / under the kitchen worktop

It's basically what's going out the flue in the condense pipe so it's products of combustion

Best option is enlist the services of a gas safe engy to put the condense right and maybe service the boiler
 
Yes, it's a problem. If this "vapour/steam" is being emitted into your house so, probably, is flue gas. Turn off the boiler and get a Gas Safe engineer to come and sort it out for you.

Broadly speaking, a condensate drain needs to be treated with as much respect as the flue. Don't mess with it or you may end up with a dead family.

So are you saying the Isar does not have an S Trap fitted?
 
I believe that model does have an internal S-trap:

but the OP's description strongly suggests either it is not performing its function correctly or there is a HX leak.

If there's an internal trap why is an external to the boiler trap required

It's prob just in case the condense line gets blocked, like on the solos

You seem to have found another version of the ISAR HE 24 than I did. The manual I cited is dated Aug 2009 and does not show an external trap. Anyway, the symptoms certainly suggest no trap (likely) or an empty trap (less likely) and either way I hope we can agree that the OP should stop using the boiler until the condensate drain has been reviewed and reconnected properly by a GSR.

2008 mine so one year apart

And tbh think there's no trap

As on hot water the trap should of filled / stopped steaming / venting poc to the room within 10-15 mins
 
Thats a bit of a no no Mr Fog products of combustion with be escaping into your kitchen get it reconnected temporarily until your revamp

Before mounting the boiler on the wall, the condensate drain (provided in the h/ware pack) must be connected from the boiler ‘S’ trap to a drainage point, preferably within the building.

Ensure that the condensate trap is full of water before commissioning the boiler . Refer to Frame 26.

from the instructions it hought all isars had this difficult to remove and prone to blocking s trap fitted

Is that from the 2008 / earlier instructions??
