I was involved with the stadium project and the project manager himself told me that face to face. I didnt question his logic but as he had overall control of the entire development I imagine he knew what he was doing.
You'd think someone would invent a scale reducer wouldn't you? Or maybe a way of recirculating the water so that once the initial scale is released, there's no more to come, a bit like central heating systems do.
I believe they use exactly that and I'm certainly no expert on undersoil heating, but the people who install these things say they need a major overhaul at least once every 13 years, so I assume they do. No heating system lasts forever, I'm lucky if I can manage five years without calling out a plumber to sort mine(though fortunately none of it is under the lawn).
This area is particularly bad for lime scale build up, up is Scotland there was no lime scale build up in the kettle at all, but since being back it has been very noticeable how much of a build up you get in these parts.
Yep, it's well known in plumbing and heating circles especially, that's why they factor it into the design. How many houses do you know that have all their heating pipes renewed every 10 years?
My sister had to have it done recently, but I guess it was longer that 10 years since the system was put in.
I don't believe anyone mentioned removing all the pipes, just that they need maintaining, the pipes were full of leaks and you can hardly fix them without removing the pitch.
A poorly designed system can scale up, but most have an inhibitor or scale reducer, plus they pretty much reuse the same water, so it limits the scale available. Water heaters can suffer because it's fresh water each time. A good system wouldn't need it every ten years. It's not difficult to factor it in.
If it's down to limescale, then easily solved my Hull Tigers friends - Oust. I use it on my kettle. You. Are. Welcome.
I know absolutely nothing about it, but he was an extremely experienced project manager in charge of a £30m plus development so I trusted him. A bit like trusting the opinion of a city by the people who live in the city.
Apart from you, here >>> "The undersoil heating pipes build up limescale and all have to be dug up and de-scaled every 10-13 years, it's not possible to never dig up the pitch." That's just desperate. They don't need to dig up to descale pipes.
You'd love it to be a vendetta, when it's simply me pointing something out, the fact this time it's to you is irelevent. It's a message board for discussion, you just can't take people having different or more informed views than you and get defensive and change tack, rather than just face the fact you get things wrong, or don't know as much as you like to make out.
