I cannot get continuous hot water at the taps. The boiler fires up ok and I can get heating but I cannot get hot water on its own - I have to have the heating on when the hot water at the taps goes hot and then cold and so on. very annoying! Also the room thermostat does not click on to operate. Any ideas?

for the HW a switch controls it, pressure switch or pressure device and micro switch. switch faulty. Thermostat not clicking, faulty.
