But the Vaillant should be the least likely to attract dirt because its piped from underneath.
The Halstead Eden is piped upwards with the same HE but does not seem to have a particular problem.
Although a different HE, the Viessmann heat only is also piped from above but does not seem to suffer either.
But then I have not met a dirty Vaillant yet so perhaps I am biased?
