My Baxi combi 105e keeps loosing pressure! It seems to be ever since I removed the bathroom radiator whilst tiling and is becoming more frequent. I replaced the boiler treatment, blead the air and repressurised the system. Was I supposed to do anything else or is this a coincidence?

when the boiler is runing how high is the pressure geting on the boiler,if you have no leaks it could be the pressure relif valve letting by(check the prv pipe outside to see if its been driping)or the expansion vessel might need recharging the 105 uses the expansion vessel for the preheat on hot water, has the hot water been ok,the pressure guage should be 1 bar cold and 2.5 max hot
