Hi all,
Recently built a house with a back boiler stove and oil central heating linked together with a system link and heat genie.
This year when I began lighting fires in the stove I noticed the rads upstairs weren't getting warm as they usually would with the thermostat. Noticed this evening that dirty hot water was filling the expansion tank and overflowing to a pipe outside the house.
The pipe entering the heat genie is red hot where as the pipe leaving is luke warm. What could the problem be?
