Only 5kw it won't get that hot.

Genuine question... how hot does it need to get then?

I still struggle with being convinced hot water is faster on routine maintenance cleans. Were all creatures of habit and work to our own default speed, it would be  hard to break that habit after all these years. 1st cleans and facias, yeah, i can get that but as an established wc who rarely does facias these days and lets face it, not all 1st cleans are that dirty, plus an additional £25 a week plus initial outlay to recoup....   Squeaky says it will pay for itself over winter yet there seems to be an increasing number of hot water users on here who wont go out when its freezing!!! why is that? Genuine question again, are they scared of breaking a window given temperature extremes of water against freezing glass? Seems bizarre that they don't when this is a perfect opportunity to work when us cold water boys cant. Im definitely not  knocking hot water users and at this price for the heater itself then it certainly starts to warrant a further look, but im still yet to see a convincing argument for it.

Also, whilst i have a lot of time for Squeaky, telling viewers he gets a commission on sales for it through his link sort of nullifies his impartiality.

I see it says suitable for univalve.
How much of a stretch is there when pulled?
I prefer as little stretch as possible when using a univalve and hot water .

Wish some supplier would make 10mm outer diameter with 8mm inner diameter flexible pole hose  and not the two layer minibore hose stuff which is to stiff at times and too heavy compared to Rhino tube. which I can only get as 8/,6mm which is too small.

Why is it to small ? Ime guessing  you are using 2 mm jets ? You  can only push so much water through them you don’t need an 8 mm supply for 2-3 mm jets

To be fair, I know Dave, and he is a fantastic chap and completely honest in what he does. 

Is this the same squeaky clean Dave who said stainless steel springs didn't work in univalves? As they were....... Um.... Not springy enough🤔🤣🤣🤣

Stainless steel springs are just as 'springy' as the cheap, poor quality springs that come as standard, it's just that they last 10 times longer!! Makes you wonder who he's working for 🤔😉
