thanks for the reply COG the 2 yellow wires are connected & the gas valve is fully on, but alas no hot water. what do the two sensors on the DHW outlet from the H/Ex do? if one of them senses water temp & has been 'scalded' in the past due to the old scaled H/Ex - could they be telling the...

sorry to drive you to drink........i have roughly measured the water output as 8 litres/min. cheers!!!

COG & DP - i may have misled you abit - it's a 350..........sorry

Thanks DP, when the heating is off the 2 pipes you mention (C/Heating) do not get hot. I have since found that when the heating is off the DHW heats fine, it seems to be when the DHW is called for whilst the heating is running - then the water only heats to warm. The H/Ex was changed due to...

Bl**dy good question, but if he wont meet appointments!? anyway, yes the boiler does 'turn off' for 12 secs or so, but when it relights the DHW (the majority of the time) only comes through warm. If the tap is shut down to just over a trickle the water heats up. Where do i find the divertor...

Sounds like the heat exchanger is on its way out, have you noticed a drop in water pressure on the DHW side?

:? Please can anyone help? The boiler has recently had the heat exchanger changed due to scale. Pretty much since then if the boiler has been running (ie Heat) & HW is demanded only warm water comes from tap. The burners appear to be fully on. Also had burners switch off when HW demand if Heat...
