Boiler dropping temperature when in shower
Hello we’ve got a baxi boiler and when we have a shower the temperature is good for about 30 seconds then it drops to Luke warm and then it goes hot again and it carries on doing this and we keep having to turn the temperature up on the Thermo static shower all the time just asked our Plumber who said it could be a blockage and it would be £208 to fix all in. Does this sound about right? The radiators are not coming on randomly like they were before and we had to have something cleaned out and some sort of bag thing replaced any help or advice would
Be welcome
