Back Boiler


Postby ParkerChops » Wed Oct 27, 2010 1:21 pm

Hi All

I have a wood burner with a back boiler hooked up to my hot water storage tank and my central heating. When the water in the back boiler gets to the right temperature the pump starts and the pipes above and below the pump get hot, but, the hot water doesn't reach the radiators. It's been suggested that I may have an air blockage. How do I remove this air blockage? The radiators do get hot when the oil fired boiler is used.

Thanks in advanced for your help.

Yes. One of the pipes to the storage tank has a thermostat attached to it which switches the pump on when the desired temperature is reached. The pipes above and below the pump become hot. I traced the hot pipe into the storage cupboard, then it disappears under the floor boards. I want to avoid ripping the floor up if I can....

Many thanks
