I have a Baxi 80eco, the pressure keeps increasing even with the filling loop disconnected and no heating or hot water on. We have to drain about 2 liters of water every day to release the pressure and the overflow is dripping water constantly, any suggestions please?

if the filling loop is disconnected, the only way water pressure is entering the boiler is due to a faulty secondary heat exchanger. It is not good for the boiler to keep on topping up as you will loose the inhibitor chemical which stops corrision.
