Horizontal flues for condensing boilers need to rise somewhat to ensure that the acid h2o vapour to trickle again down the flue and be safely and securely removed by using the condense pipe.

If it simply cannot pitch downhill, it could operate horizontally but ought to often remain below the entice outlet. It’s a smart idea to utilize a vacuum breaker for the entice (see illustration beneath).

If one particular suspects a freeze, confirming this with a visual inspection is step one – a frozen pipe could present noticeable ice at its outlet or together its duration.

It is because in a very condensing boiler, the latent heat flue gases could be repurposed and reused to preheat the chilly drinking water coming into the boiler. In the course of this method, the temperature of the flue gasoline is promptly reduced from all over 130℃ to 90℃.

Condensate h2o is acidic and for that reason have to be transported in plastic or PVC piping (at higher temperatures - aluminium piping inside the boiler).

A further website preventative evaluate is to put in the condensate pipe at a gradient. This makes sure that the condensate flows clear of the boiler and doesn’t remain stagnant while in the pipe, cutting down the possibility of freezing.
