Ideal Logic Boiler Spurting Water Occasionally

harringtonp

Hi,

The ideal logic boiler had stopped functioning due to pressure loss (after a power cut i think) so I opened the inlet tap temporarily to allow some water in and repressurise the system. Once the gauge hit about 1.5 I closed it. The boiler then worked as normal heating both water and radiators.

However during this "restart" process 3 spurts of water (small 1/2 cup size each perhaps) came out of the green highlighted outlet. There hasn't been any more for the last day or so. Any idea what this is about ? if it is a safety mechanism, it seems strange the way it is completely open and water can spurt everywhere.

Your external/condensate drain (the white pipe) has pulled out of the pressure release valve. Loosen the black nut at the boiler and push it back in, tightening the nut again.

As for the spluttering, it may have been doing this all along without you noticing it. Is the pressure going high when it's fully up to temperature?

Thanks, hadn't spotted that and its quite likely it came undone when I pulled out the spice unit in front of it to get at the inlet tap.

Not sure about the spluttering, just keeping an eye on the house while somebody was away. But as far as I know apart from something causing the occasional drop in pressure, the boiler has been fine.

You (or friend)may be developing a problem with the expansion vessel, someone wants to watch the boiler pressure as its coming up to full temperature, if it hits 2.8/3bar then the PRV will lift and spurt out water and eventually system will require topping up again which will, in a relatively short time, cause corrosion and sludge in the whole system and a pile of grief eventually.

Just be careful with that. It's considered part of the flue system and if the trap runs dry there might be a possibility of fumes (incl carbon monoxide) escaping there. Perhaps the house owners would like you to call a registered gas installer to redo that joint and give it the once over.

I thought (wrongly) it was the PRV teed (even more wrongly) into the condensate drain, so that IS the condensate drain?. So no problem with E.vessel then.

Thanks Guys. Help appreciated
