Hi guys, having a problem with the above electric boiler and thought I'd ask here in the off chance someone may be able to help! Basically I am not getting hot water from it through to all taps and the shower (I live in an apartment), it is just luke warm at best! When I touch the pipes connecting to the boiler they are too hot to keep your hand on so it seems to be heating the water up nicely. I have found a manual here and it says to turn the blending valve anti clockwise to mix more hot water than cold water which I did last night and this morning the shower was exactly the same Don't really know what else to do, does it look like I'll need to call out a plumber? The thing is it used to be a lot warmer than this, never over the top hot but certainly never cold, would cleaning it solve anything? Any help at all would be appreciated!
