Help! My Greenstar 28i installed 4 years ago will give DHW but the CH shuts down after a few minutes running. Have checked that the pump is turning and the RF is synched with new batteries installed. The radiators start to warm up and the pressure rises from 1.0 bar to 2.2 bar and then it shuts down. The baffle chamber also gets extremely hot and is untouchable just before the unit shuts down. The central heating has not been run for around 6 months and foolish me has never had it serviced. Any suggestions.....all radiators have been bled.
