Title: Micro bore or mini bore
Post by: Anthony Jardine on December 03, 2018, 04:59:44 pm
For those that use Hot water, which hose do you use

Minibore or microbore?

Do you you use the hose especially rated for hot water and who do you purchase from?

Thanks

Tony

ALWAYS microbore never minibore whether hot or cold.....i use the red 6mm pure freedom hose which is ok as grippatank and gardiners hadnt got the 6mm thermobore in stock when i had my heater fitted at the end of last year......

I use Gardner's normal micro bore, the yellow cheap one, and have done for the past 6 years

I  have used minibore for the last 9 years ...never used microbore so can't comment but the mini bore is very robust had the one hose from day1 ...9 years old  now :)

Minibore.

Better flow rate, less stress on pump and battery.

Lasts ages as well.

i guarantee youll NEVER go back to minibore once you ve used microbore....your just making your working day harder than it needs to be.......

Daz, microbore is definitely lighter and easier to handle, but minibore paired with an electric reel is my choice for the reasons stated above.

It’s really just personal preference because they both work well.

Micro bore mini boar is horrible stuff to drag round , once you get used to microbore you will wonder why you ever used the other

I vote microbore - lighter - less snagging - all round easier to use

as Daz said you won't go back to mini after using micro

I have the best of both worlds. Microbore hose but I use 8mm internal flexible lightweight pole hose so more flow without dragging the extra weight of minibore hose along the ground. Allows me to turn the flow down saving on my battery juice and still keep a higher flow than using microbore hose with 6mm internal pose hose. Always use John guest non return valve at base of pole so no waiting for water to go up the pole  ;D

All this talk of more wear on a pump
And battery because of 2 mill difference.  ???

My last system (pump and battery) lasted 6 years with microbore before I sold it on.

I really don’t think it alters the life time of pumps and battery. If it does, it’s tiny.

It must mean something. In the early days Williamson pumps would only offer warranty on Shurflo pumps if they had been used with 1/2" hose.

I opted for minibore as it was closer to standard 1/2" hose than microbore was. I decided that I would 'carry' my own warranty on using a Shurflo pump with minbore, a decision I never regretted as it was so much easier to manage than 1/2" hose, especially in winter with cold water.

Microbore is just over half the internal area (volume) of minibore, so 2mm diamt makes a big difference.   
(minibore = 50.27mm2.
Microbore = 28.27mm2.
1/2" hose = 530.93mm2 - 5.5 times the internal area of minibore.)

Jonny,

It does make a difference in flow rate for me.

But let’s be honest - who cares! They both work.

My preference is just a wider bore for more flow and I find my battery seems to fair better with the larger bore.

Spruce as always has the details!

But again, it really doesn’t matter. If this is all us windys have got to worry about, we must be bored  ;D

you dont know anything else apart for using minibore.....if you ever buy some microbore for your next hose you ll know what im on about...... :)

same with xtreme poles,hot water and electric reels,put them all together and you have a much easier working day....

3mm.

I also use Gardiner green 5.5mm pole hose. Which I found (to my amazement) produces a much better flow than standard 5mm. Amazing what half a mm can do for flow!



Title: Re: Micro bore or mini bore
Post by: Smudger on December 04, 2018, 08:43:30 am
so your restricting the flow down to 5.5 mm before the jets then ?

negates the use of the larger size reel hose really

Hi Darren, it doesn’t work like that, basically the longer the thin hose, the worse the flow, if you use  100m of microbore into pole hose, you get less flow.

I know this because I’ve used both.

Of course you restrict flow as soon as it hits the thinner pole hose, but ultimately you still mintain a great litres per minute at the brush head. As said the 5.5mm pole hose helps, as does the 3mm jets.

What we need to understand on this forum is we all do things differently, and guess what, that’s ok  :)

For me having used both, 8mm gives me far better flow rate. For others 6mm suits them.

I can only vouch for what gives me the better result. But squeezing water through 100m of 6mm hose effected flow rate for me. Regardless of the thinner pole hose.





Title: Re: Micro bore or mini bore
Post by: Smudger on December 04, 2018, 08:54:19 am
where did I say it was wrong to use 8mm ?

I used 8mm for the first couple of years of wfp then moved to 6mm - the change in flow was minimal but then I use fan jet's which have smaller aperture and spread the water better than pencil jets so the benefits of easier working with smaller diameter hose were well worth it for me

The initial question was with regard to use with hot water.

The viscosity of water changes with heat so warm water flows better than cold water. In the extreme, ice doesn't flow at all. Most window cleaners who have warm/hot water use ordinary microbore.  Standard minibore hose doesn't work well with hot water. I know when I tried hot water through my minibore hose it became like an elastic band.

Obviously there is speciality hoses that are available which work better with hot as the composition of the material the hose is made from is different. I'm not sure how easy hot water hose is if you revert to cold water in summer for example.

I see Grippatank have a note on their site under the 6mm Hydroheat hose they sell. They don't recommend 8mm as the heat loss is greater and affects the water temperature output.

I didn’t say you did say it was wrong.

It’s the same principal as pressure washing, although your squeezing water through a small jet, you still need a larger hose to carry the water to it.

If you used a thin hose through the same jet in pressure washing, you’d lose LPM.

I find the same for window cleaning.

Both work. Chalk and cheese.

One just provides increased flow, the other loses a bit of flow but is easier to handle.

I’ve just purchased some hydro heat 6mm from grippa, hopefully won’t be so stretchy and keep  heat in a little bit more

 I’ll keep my current one and may swap back in the summer if the hydro heat is not good with cold water

If it’s fine I’ll just keep it as a spare

id be interested in your review of this hose tony when you ve been using it for a few months......i used to have the red 8mm thermobore that gardiners used to sell for hot water use.....it was a nightmare,far too heavy and cumbersome to drag around......gardiners have discontinued the 8mm and they dont sell any red thermobore at all now(even the 6mm version)......

Jury is still out for me on the Hydroheat hose.

My powerup hd is still Struggling to reel it all in. It’s very grippy, and heavier due to it being thicker. It is the same 6 mill internal
Though.

I’m thinking of going back to my hi vis hose from
Circuit hydraulics just to see the difference.

I loved using the thermobore hose from Gardiners, best hose I've ever bought. Had to abandon it in the end as it's been run over and spliced and rejoined so many times I had to buy the red hose from window cleaning warehouse, not keen on it as it's not so supple. Goes like cardboard using cold water on freezing days, ok with warm but not cold water.

I’ll let you  know Daz how it goes if it’s too heavy I’ll go back to the blue hose, down side is I like a really high flow 60 at least 65 suits me good and the build up of pressure with the softer hose makes it prone to swell and get heavy, so set on 50 today  feels so slow when rinsing

I’ve been using the blue circles hydrolics 6 mm but it does how quiet spongy with the heat which is great cold

How long you had the the HD Jonny as mine are  just over 2 years old now and sames been happening, last few months replaced the motor on Friday and it’s been awesome this week so far, pulling everything back in with a bit of oomph again

I think with Oliver’s help worked out why my heaters not been getting to full heat, I’ll do the adjustment on Friday when I have some time and hopefully get a bit hotter

We regularly join two 100 meters of microbore together on big commercial jobs and don’t have to adjust the flow rate works fine no noticeable difference in flow rate and we are working at 60 feet high
