Veissman 101 boiler condensate.

[alan48]

Hi all
Is it normal for the flue outlet to be dripping water onto the outside drive and window sill when its running, i say no as the condensate should run back into the internal drain.
Views much appreciated.

You will never stop it dripping, but it should not be dripping excessively. As you say the flue terminal should be installed with a fall back to the boiler. If it is a nuicence them maybe consider having a GSR look at installing a plume management kit. If it is possible for your boiler.

Darren has nailed it above , however if you go it the boiler with a very small spirit level you should be able to see the flue “fall “ back to the boiler .
Has it just been installed?

Yes, been in about two months, appart from that and a few other niggles its been excellent.
Have underfloor heating so its set up as a s system, had to disconnect manifold thermostat and pump on the floor manifold but that solved a couple of issues.
Good boilers.

Just check if it “ falls” , if its level, or “ falling” the wrong way

Well that doesn't sound right.......

Maybe not but it worked.

And how hot is the floor getting? The mixing valve and pump is there for a reason.

The floor seems to be warming up as before, I agree with what you said, the pump and manifold thermostat are there for a reason and they are an integral part of the design, however the system would not work with them connected and the only solution was to disconnect both.
Before anyone says call back the installer he knows less about it tham me.

Sounds like you need a new heating engineer then. Without the mixing valve you run the risk of damaging whatever floor covering you’ve got as the floor temperature could easily exceed what it’s meant to.
Also I imagine the UFH won’t be as efficient to run.

Sounds like it is not wired up correctly. You need someone who is experienced in controls and how to wire them up. We see it all the time with more complicated set ups not wired up correctly. We end up totally undoing the control centre wires. Then starting from scratch, belling every cable there is to find exactly where each cable goes and what it should be doing and where it should be connected to for each individual ancillary device.

Your probably right, but I had a real problem finding this one and he assured me he was familiar with ufh systems and had installed a good few.
I think the real issue is that the ufh system was pe existing, installed by me, and had been working successfully for seven years or so and to be honest the two issues i had with it after the new boiler was installed was resolved by myself.
The ftemp is much the same as it was before so hopefully it shouldn't cause any problems.
Thanks for taking the time to respond.
