Thanks for your replies everyone .
Here's an outlier.
I have 40m reinforced pole hose connected to 60m if old microbore on my Claber hand reel. Light as a feather.
Why people use microbore let alone minibore is beyond me.
But then I don't use a pump controller either.
And I use an immersion heater for warmth.

How is the immersion heating fitted to your tank, is it a separate fitting or on the lid of the tank, got any pics or dealers that sell them?
Actually , no need , I’ve just looked at water heaters in a few websites, far too much money for me, 3 grand plus vat 😧
An immersion heater plus fittings is a couple of hundred quid. Should be fitted as close to the bottom of the tank as possible using a mechanical flange.
That sounds a much better price, have either of you got a picture of how they’ve been fitted ?
The reason I whinged about the ones for sale on a few suppliers, I’m not doing as much work now, after I had that fall just about 41/2 years ago ,and had to have half my left skull removed to stop the inside bleed . So during my off for sickness , a lot of customers got a new wc . Enough of that it’s been on before during my sickness , but’m back to work which I enjoy doing .
