We had a heatline boiler installed a year and half ago, we are on the 3rd floor so never had great deal of pressure but noticing a drop in the dhw to the first sink and all other sinks including the shower, its down to almost a trickle now. are there any filters that could be clogged up?? Everything else in the boiler seems to be working fine, although now and again the pressure drops below 1 bar and needs topped up and our central heating goes a bit cold??
Any suggestions appreciated..... :D
