Hi, i have a external heatslave 18/25 oil boiler. The CH is working fine but the HW only works for about 2 minutes before it goes just warm, the only way to get it hot is to have the tap barely running. Its like the water is going through the boiler quicker than it can heat it.
I have removed the actuator from the diverter valve and manually changed the flow from CH to HW and it makes no difference. The radiators dont get hot with just the HW on.
The flow valve is working as the boiler comes on, when turning the tap on
I am going to remove the heat exchanger next to see if it has and blockages.
Does anyone have any suggestions on what it could be.
Thanks Owen
