Diverter valve..little moter(egg shaped) that shuts the radiaters of to give heating prefferance to the hot water when a tap is run

Mines next to the pump,one pipe comes out the boiler,one goes to tank,one goes to the radiaters.says honeywell on it and has a little lever on the back so you can latch it on to heating water

You'll need to remove the cover. If your boiler has a "summer" setting, activate that and you should hear the diverter valve moving clockwork whirring.
