Old Stelrad system thats been in around 17years, not really pwerfull enough for heating, cold and hot tank feed in the roof. Plumbers ben today and said that a decent combi condenser like the ideal one i mentioned would be ok, 1 bathroom toilet and sink, 2 shower sink and toilet rooms. hence the 2.5.
