and its thermostat rage is 15C to 30C. 5C to 15C would suit my use-case better.

An incandescent light bulb (100 or 150W, or more than one). I expect you
(or someone) will have some lying around. Put it/them in a box if you
don't want the light.

Unfortunately space is tight in the porch. No socket for a blub, either
of those tube jobbies looks a possibility, but for tonite I am establishing need by moving a max/min thermometer into the porch. Down to 6.5, so far. Min external temp supposed to be -1 to -3. We'll see.

One thing to take into consideration is the range of the inbuilt
thermostat and how it operates. In reality it must be highly highly influenced by the temperature of the tube itself being internal to the enclosure.
With a tube heater without an inbuilt thermostat and a separate plug in thermostat I'm sampling the temperature approx 600mm away at the plug
socket hence more accurately the temperature of the room (old outside
toilet now with an insulated roof (no windows).

JFTR my unprotected outside tap, which is on the exterior wall of the
utility room the other side of which is the washing machine, freezes when
the outside temperature reaches a sustained -6degC; above that it’s OK.
I would be surprised if pipes in your side porch froze at anything less, unless a ‘beast from the east’ turned up.

Plugging a device consuming any amount of power into a lighting socket was, I agree, what out forebears did in the early/middle parts of the last century, but today it is frowned upon.
When I said, "plugging direct into a socket would be favourite" I was referring, obvs, to a 13A socket in the wall. And using an incandescent light bulb in any sort of temporary arrangement is inviting broken glass everywhere.

Search me. Ask Mr. Able, it's his idea to do so, not mine. I'm looking for a heater, which, natch, plugs into a wall socket.

A standard bayonet fitting would be more useful, as you're more likely
to find an incandescent lamp with that fitting lying around.

I have something similar to

or

but _without_ the built in thermostat. Mine is then connected to a
mains plug in thermostat where i can set a frost protection temperature. >>>>
I'm not sure what the lowest setting on the linked heaters.
One thing to take into consideration is the range of the inbuilt
thermostat and how it operates. In reality it must be highly highly
influenced by the temperature of the tube itself being internal to the
enclosure.
With a tube heater without an inbuilt thermostat and a separate plug
in thermostat I'm sampling the temperature approx 600mm away at the
plug socket hence more accurately the temperature of the room (old
outside toilet now with an insulated roof (no windows).
Check also Ebay for greenhouse tube heaters without an inbuilt thermostat >>>

Vast price difference in pricing between Chinese and European suppliers.
How can such a product be available in 5m interval lengths?

If the heating is done by resistors (resistance wires) in parallel, then there can be as many as you require. Assume every cm there is a 230kohm resistor across the live and neutral. Every cm will therefore provide
0.23W heat - or 23W per metre (or 115W/5m). Just keep adding lengths
until you get the desired wattage.

Is that how they work?
One of the e-bay adverts proudly mentions the use of copper wire!
So parallel conductors set in a marginally conductive matrix?
