this "pasta twist" effect started happening about a month into using hot water.the whole 100m has had to be binned today.ive been using thermobore with cold water for over a year now no problems then today it burst about 50m in. ::)roll.water all over my van as it burst while still on the reel.
anyone else had problems with thermobore when using hot water?temperature was at around 30 degrees at brush end.the pasta twist affect is over the entire 100m length.

only been using hot water for about 3 or 4 months with this hose.
-
it happened to me too . its the hot water . that hose doesn't like it too hot . I've got a 2nd hose just the same but since turning the heat down its been ok
-
Wow that looks bad, I've had 2 reels of thermobore for about 2 years now and at high temperatures 50-75C but I do have the pressure (not flow) down as low as I can, I use a pressure switch rather than a controller to adjust the pressure. I only recently had to chop a 6ft length off the end due to a burst, but that was probably from a gate.
How hot do you have it and what pressure?

about 30 degrees at brush end at the moment simon.60 on my digital flow controller which i dont think is excessive.i like a nice high flow.helps me work quicker.
-
Daz try the 8mm ThermoboreBore hose the red one
You get a much better flow as its a lil bit bigger Gardiners 🌝🌞🌴
-
waters to hot you need to cool down. 8) 8)
-
I'm on my second reel and that's showing signs of delaminating too. Last time I complained I had to check my records - I'd had it well over a year so can't complain really. Never managed to cook it as bad as yours though. ;D
-
im thinking of ordering the thermobore red hose (8mm).in all honesty i dont think this orange thermobore is up to the job.i dont have my water scalding hot but i do turn it up for first cleans and add on jobs.

luckily i had this spare microbore and hose reel although ill just be using cold water with this hose.this hose was sent to me a while back FOC from alex to replace some other microbore that had bubbled up(just using cold!). ::)roll
-
We have 2 reels of microbore running hot water for over a year with no problems.
I personally would stick with the 6mm microbore, the 8 mm will be heavier and take more space on the hose reel
-
lee is it gardiners hose your using?orange thermobore?or a different hose?
cheers
-
It's gardiner orange thermobore
-
Ive been using the Gardiners orange Thermobore since its release about 2 1/2 years ago, its still in great condition
-
There is no way thermboore will do that at 30 degrees.Its had 65 and up to produce that result.
Daz so often you stated quite clearly on here that you use your water a hot as possible and I have been waiting for this to happen. Thermobore has polyurethane as a mane component which is only good till 65 degree after that the wall will loose its structure. Just watch that yellow hose fall apart. You will have to use a hot, power washer hose next and that`s very heavy.
Thank God its the hose that went and not you heater. Its just a matter of time before someone blows up his heater and has a major problem.
I have watched my pump push water into my system for 30 seconds after I close the pole tap and often thought it quite dangerous as the heater system has a 3.5 lit ( 7 lit a min pump) excess as well adding heat before it shuts off the pump and then the boiler. The pressure must be enormous.
-
Agree, too hot.
Had a standard hose from pure freedom about 5 years now, been hot for over 2 years and no problems. And hose across roads most days with vehicles pounding over it. Keep heater on summer setting and both controlls at half. Flow rate of 60.
-
ive just ordered the thermobore PLUS red hose.8mm.
seriously guys the heater dial was just a bit higher than the min setting.maybe the smaller hose has been giving a bit too much back pressure.with 8mm hose ill probably be able to turn the flow setting down a bit and still get the same flow at brush end. ;) ;D
shammy im using the emergency hose and reel with cold water mate till my new hose comes. ;)
ive never had the heater setting on half way even on minging first cleans and UPVC cleans!
-
It could be the controller set with a too high D/E, i know i had to change my controller from a Varistream to a Spring/Gardiners controller because i couldnt adjust the D/E enough on the Varistream ???
-
My thermobore has been fine just using the pressure switch on the pump.
-
Dazmond aside from the hot water use , You have the same set up as me with StreamBox and orange thermobore it has always baffled me that you your flow rate is so high .
Although i do use 1mm jets so i would assume the back up of pressure of running at a flow rate of 60 plus 30c water is what has caused your meltdown .
My current flow rate is 30 with cold water and normally 24 in the warmer months , Hope you get things sorted . Mike

This is why I pull my water through rather than push. No pressure on the boiler at all.

There is much confusion about flow and pressure. Heater are regulated by the pressure which will be high pressure with a low flow will still make very hot water. Flow is the amount of water passing through the boiler and the longer it stays in the boiler the hotter it will be. e.g you can have a 100 psi and a flow of 3 liters a min which will core out of the boiler very hot. I have a 5 liter a min boiler and a 100psi pump and at 7 liters a minute PUMP it will never boil. If I turn my flow down, my psi is still 100 but my flow is 3 liters a min and it will get very hot. So flow does have a very important role is heating water. The psi is the head of the water. e.g. pushing the water up a high pole+PSI

I tried having my pump after the heater, could not get it to work.
As soon as I moved it before the heater it worked no problems. Maybe the pump is the key, only have sureflo pump 5lpm.
-
That's what I've got. Don't get any problems now. Used to get so much pressure in the boiler it would blow hot water out of the valve underneath.
-
Ive got standard hose but i put a loop back into the tank before reels, so when i uplug the hot isnt still pumping round the reels and dumping back to the tank.
I learnt this from years ago when my 6mm microbore blew up to the size of a garden hose lol. Need to release that pressure somewhere.
-
i just adjust the de detection on the controller, when the hose is cold first job in the morning i have to turn the de up, when using hot i shut off the flow and within 5 seconds the pump stops, never have i once on any microbore or thermobore hose have i broken one
Dazmond your obviously doing something wrong, either too much presure (likely) or too much heat (not likely)
-
we use gardiner 8mm red thermobore up to 70 degrees and no problems. its thicker and tougher
-
I think it's a pressure problem. How long does it take for your pump to cut off once you stop the flow?
Time it at the beginning and end of day with the boiler switched on. The reason why i say both ends of the day is the battery voltage can make a difference to how the flow controller works. It should take well under 10 seconds, if it's taking longer then it's pushing water through the boiler and it has nowhere to go, so the water in the boiler will rise to very high temperatures over 100c and yet not turn to steam due to the high pressure. You then push the water around the hose reel parking it at various stages in the hose which is where it causes the damage.
I'd seriously consider using the pressure switch on the pump to control pressure and not the controller, you can still use a controller to control flow speed. A pressure switch is far more stable at controlling pressure than an electronic controller in my experience.
If you don't get it sorted with the 6mm the 8mm has the potential to be even worse due to more room for expansion, meaning greater time to build pressure.

u cud sell that piping on ebay- artistic /crafters project
-
Daz, i use the red thermobore 8mm, it is a great hose but i think your hose reel will be to small for a 100m 8mm
-
ben i have a redashe koreel hi vis reel.im sure 100m will fit.the claber reel is my spare emergency reel with 100m of standard microbore on.ill be just using cold water until my new hose comes.
simon you could be right.it takes about 20 seconds after turning tap off at pole end before my pump shuts off!ill have a play with the dead end detection when i get my new hose.

Daz, those don't look like Berghaus boots. ;D

JCB black riggers from B&Q mate!keep feet nice and warm and dry!ill switch back to the bergaus ones in spring! ;) ;D
