    Not AFAIK. The only oddity is that some are Normally Closed and others are Normally Open, but this is obviously something a BDR91 can handle!

    Out of interest, my 637 takes ~30 mins to hit flow temp first thing, it's rated to 24kW currently, doesn't appear to be cycling. Is this a symptom of the rating being too low?
