Hi,

My water plant is kept inside a large brick industrial unit with space for a vans in it  PLUS the water plant.

To winterise it I'm thinking about:

1. Attaching a roll of insulated foam matting (camping matting / yoga-style matting) to the wall a few feet above the water plant.
2, Putting an oil filled rad between the plant and wall.
3. Unrolling the matting so it covers both the plant and the transfer hose in cold weather.

Maybe you have a better idea?

A water plant?

A lily?

I would imagine the best way would be to totally box in the water plant , all sides top and base if possible , if me i would use studwork timber frame 2 inch celotex boards and then faced with  OSB , then put the oil rad in with it all , just remember to have one of the sides on hinges so yo can get in !

I think that if you do this without the oil filled rad and use 1" Celotex it will be just fine.  If you're using a booster pump inside (and you should be!) then you'll have no problems- the Clarke 250 booster so widely used is 1000w and bungs out a decent amout of heat - any booster pump will heat up the space.  My water's produced in a shed with a 1" insulated roof and never gets anywhere near freezing.  If you have your water tank inside the insulation then you'll also have a huge mass of water keeping it above freezing.

Just looked at the price difference between Celotex  1" and 2" - possibly worth going 2" as it's not a big difference even if it's possibly overkill.

What's this got to do with window cleaning???

Seriously?

[P @ F]

I would have thought that stopping window cleaning water from freezing would have been a BIG hint !

Whatever...

Apologies - I flicked through this. I actually thought we were talking about some sort of growing plant in his unit lol.

I need a day off lol.

No, not all. 
You were confused by the modern under use of the wonderful word 'winterising'.  Then the OP says that he has a water plant to confuse us further.
I think we should make a concerted effort to use the word 'winterising' more.

I've a water plant in a wooden shed in North Scotland.

Never had a problem with it.
