It will probably have a diverter valve - likely in your airing cupboard - the valve sends the water to either the hot water tank or to the radiators and sometimes to both.

My guess is that your valve is stuck in the mid position and not switching to the water only position.

I think it is gravity fed??

Possibly an issue with the 3-port valve (Assuming the hot water is a pumped system and not a gravity one).
