For water to make its way around the central heating system, the water pump needs to be in top condition. If the hot water isn't being pumped away from the boiler then it will begin to overheat which will lead to short cycling. If this turns out to be the case then you'll need a Gas Safe registered engineer who may have to replace the pump.Get Price
