I don't really :) but I had noticed that when the heating is on the hot water is always stupidly hot, whereas if only the hot water is on it is as hot as I would like it. I therefore assumed that the heating was affecting the hot water and turned the hot water off to test it!
I have now...
I understand what you're saying, but surely I should be able to have the heating on and NOT have hot water if I so choose. My hot water is permanently set to off, but I still have hot water.
Hi, I have a Worcestor Bosch Heatslave 20/25 (combi boiler). Recently, when the heating is switched on I get hot water despite hot water being switched off. If I only switch hot water on, then I get hot water as expected. Can anyone help? Thanks!
