Around 2 years ago I changed form the larger diameter Hozelock type of hose over to microbore. Last inter was fairly mild and I'm thinking, as this is my first full winter with microbore, do they freeze easier with the smaller bore? Perhaps some of the more technically minded guys on here can answer that.

Gary's right, warm/hot water can still freeze on the ground.
We've not had the Mpemba effect mentioned, for a while. I enjoyed those discussions  .

Mpemba schmemba.lol

 
Just be careful out there.
I'm childminding, again  , but we will be heading outdoors. I love this weather and I saw a kingfisher, yesterday.

I've always found -3 to be workable -5 just too cold for the brushes/jets and me.

I would say that microbore does freeze more easily - though I haven't been able to make a direct comparison.
I'm just applying laws of physics really - the less water there is, the more quickly it should heat or freeze.
There is a lot less than half of the amount of water in microbore as in an equivalent length of half inch hose.  If the water is kept running there ought not be an issue inside the hose - it's when you stop that it can become a problem.

I've managed a -2 before now but would prefer 0 or above really.

Plenty of hours to work and make a good living throughout the year without the need to work in minus 5.

, no I don't use hot water - I just can't justify the cost.

An immersion heater is very cheap (and easy) to install; if you can park off-road.

I watched the weather last night , -7c was predicted , i couldnt be bothered to run the lead and heater out , thought i would take a chance !!!!!!

Just been out to check the van .........oh poop , all hoses, di, pumps , strainers , L5 completely solid

Hot water makes no difference in freezing weather. I was told hot water freezes quicker than cold. Either way. It freezes on the ground. I always wfp peoples doors. Frozen water by a front door is a no no if you ask me. Dare say Insurance would be a pain in a claim. This is one time Traditional wins...other than using a ladder on icy ground

What kind of vans do you people drive  -5 outside but van is well above freezing

[jk999]

Still need to  stop pumps from freezing up even if your not gonna  use  them

I've attached two pumps and the flow controllers to a bit of ply wood and have an electrical connection so that they can be unplugged from the cable that runs to the battery.

My tank outlet has a inline tap I can switch off.

This means I can disconnect the pumps from the electrical cable and the tank outlet and just carry the board into the house.

It doesn't look pretty, but it works, and it takes less than a minute to do.

I don't normally bother doing this if I'm using the tank's immersion heater though, because that turns the tank into a radiator and keeps everything from freezing.

Just got back in from a large commercial job. Heater on the whole time - water ok at the brush but it did start to freeze once. Water on the ground freezing pretty quickly so plenty of salt.

[dazmond]

im not going back to work till the 5th jan.already had 9 days off.

all i would do in this weather is put an oil filled radiator in the back overnight

sweeping brush and ice melt grit

rigger boots,thick socks,beanie hat and glacier perfect curve gloves,ski pants,fleece,waterproof jacket...and crack on.

i use hot water and thermobore plus red hose anyway in winter so no problems with water freezing in the hose or jets.

for certain doorways id trad them instead of leaving water around and grit/sweep away water around paths.thats it.

...oh and 2 flasks!one for tea and the other with hot soup in!

i wouldnt be starting work before 10am though and probably finish at 330pm in this weather

[jk999]

Tosh  is the heater in tank one that you fitted or one of those you just drop into top

We had -4C at the coldest part of the night and nothing froze in the van not even the few inches of water in the bucket.

Good advice
I've done exactly the same for years, not having the luxury of heating my van or even being able to park any reasonable distance from my flat even if I were to be able to run leccy out to it.
Don't over complicate things and keep them cheap and simple and there will be very little to go wrong

Y wfp shops???

why trad them when it takes a 3rd of the time with wfp
