I have an Amptec electric central heating boiler that serves my radiators only. My hot water system is separate and comes from an unvented tank.
I assume that the Amptec boiler is classified as an unvented system.
I had my radiators replaced and one removed. The system was drained from a draining point. Now it's refilled there is clearly a blockage as the water won't pump around the radiators. The hot water seems to be travelling in a loop from the boiler through the pump ie only going into the pipework a foot away from the boiler. The pump gets very hot.
I've bled the radiators, bled the pump and bled the vent at the highest point of the system. I've had two plumbers out on very expensive call out charges: the first said it was a blockage in the pump but it was too hot for him to bleed (so I did it, there was little air in it). The second said the system needed a power flush but was here for 10 minutes and didn't re-drain the system or look at the pump. What can I do myself? Do I re-drain the system and see what happens when I re-fill it? When the radiators were fitted the plumber did not flush the system through afterwards.
Hope someone can help me as I can't afford the £400 for the powerflush, and what happens if that's not the problem.
