There is one place I do work on with these. Every new tenant has to

Does this mean you shouldn;t use those "nice" MDF radiator covers over
them?
I have several in 100% original victorian rooms which I need / would
like to
hide.

The issue is that anything that resticts the flow rate through the units
increases the temperature of the air emerging from the top of the unit.
If the unit were a fan or convector heater then likely a safety cutout
would trip and the temperature would reduce directly.

With storage heaters the trip will prevent them reheating the following
night, the bricks inside are probably still at 300C or more.

MDF covers will probably not affect the overall heat output but it will
mean that the air emerging is at a higher temperature. The manufacturers
may have a view on the matter - although they are likely to err on the
side of caution. It might also cause them the cut off to trip.

The particular one I saw locally had a mesh grille (sp) on the top and front
so air flow from the top shouldn't be an issue. At least I know what to look
at for.
