As the title suggests, I have a WB 28HE system boiler, which there is
nothing wrong with. In fact it's very good.

My question is...is it normal for the cover to just cover the front and
sides on this boiler? My boiler has just that and has the top and bottom
exposed.

As I say, the boiler is very good and the cover doesn't impede it's
performance. Just wondering if this is normal nowadays?
