can I get my Glo warm swift flow 80 mended or what do I replace with ?

thats the answer for...duh...I haven't a clue whats wrong....wheres my money and the door.....!

if the intermittant running is on dhw demand only, either the inline filter is partially blocked (remove and clean) the dhw heat exchanger is scaled up (most likely problem) or the dhw thermister is faulty (they cost under £10 and fit in minutes)
