I have a E tech s 240 boiler that was installed in my 3 year old flat.The boiler is connected to a Salus EP100 programmer. It's a tank in tank, electric, unvented thermal store system, as far as I can gather from reading online.
We can only get the boiler and it's built in tank to heat up if we activate the domestic hot water circuit. Whilst this is happening, if we activate the central heating circuit simultaneously, the radiators warm up as expected.
However, if we activate only the heating circuit, even with hot water already stored in the domestic tank, the radiators do not warm up. The outflow pipe from the boiler for the heating circuit gets noticibly warmer, but the radiators do not. Activating the central heating circuit when the domestic tank is cold does not cause it to warm up and circulate heat either.
So I'm seeing two possible issues... something is preventing the central heating circuit flowing correctly and something might be preventing the elements from switching on when the heating circuit is operated independently.
A chap from Pimlico Plumbers has already been to examine the system but didn't seem to have a grasp of the problem. He tested the electrics and said all was OK, then told us the problem was the summer/winter switch on the front of the boiler, which it was not! So rather desperate for some help!
