Hope you used a special transformer. A dimmer gives pulses of

mains
voltage
that are a lethal as the straight mains.

And why is this a problem?

AFAIK heating cables are mains voltage anyway - I have one in

home
made
propagator controlled by a rod thermostat control no transformer

AFAIK

Blimey


What's the problem here Franz? Soil warming cables, thermostats etc.

all
standard kit intended for greenhouses - as is my mains electric

heater,

I would not go near mains heating cables buried in damp earth. Full
stop.
Low voltage units are available for this obvious reason.
