The other day my hot water cylinder was taken out and a Vailient Combi boiler fitted , first my shower (Mira Excel) lost all pressure and the plumber took it apart to find lots of debree in the filters , after cleaning the filters out the shower pressure got better (acceptable- just to get the pain in the arses out my house! ).. and since then the temperature has been the same - give or take a few degrees - its been really hot whether it be up at number 8 or down past the Blue setting number 1- (as you can imagine that first thing in the morning you think your skin will fall off with the heat! ) -- My landlord says its fine and should be that way-- I need some advice on what the problem could be , someone mentioned the cartridges inside may need replaced now £70 roughly ,what do you think?

Measure the temperature of the water. Factory setting on water heaters is 120F.
Yoursw shouldn't run much above 135F. If it's higher then that have the temperature setting on the boiler reduced. Good luck, Tom
