Dee Day For Butcher?

[12th Man]

According to an "Inditherm" manual the costs are nothing like that ! Inditherm is the type used at the Falkirk stadium and at Chelsea, not sure what we have but it gives comparison costs.

.To install that, the whole pitch has to be removed and then relaid,ours used a plough style machine which split the ground and buried a pipe in it afterwards to become a giant radiator, going by the TV coverage when it was installed.

IMO From looking at your attachment, the inditherm looks like an expensive bit of kit and I don't think that the 'salesman's' energy savings figures could ever be recouped. Due to the overall cost of the installation, the equipment, maintenance and lifespan,especially as it will rarely be switched on.

The installers must have also found an installation/manufacturing safety fault with the system, it may only be a SELV system but it cant be run at 50v all the way from the control panel the volt drop would be too great, so they must have 415v cables under the pitch and installed in series, thats my assumption anyway.

So I'm glad we have a nice and simple low maintenance alkathene piping system,

To stay on topic d day for butcher, no.

Inditherm Plc is a company that develops and supplies heating systems like that installed at Falkirk. They also supply a polymer based heat transference oil which is also called 'Inditherm'. This oil is heated using a boiler or electric heating elements and is pumped through underground pipework. Because of its excellent heat transfer properties it is more economical than water. Either way it could well be what we use. Another product on the market, produced by Dow Chemicals, is Dowtherm and there are various other products available. All good quality. The advantages of using those products is their hear transfer co-efficiencies. The cost per therm to heat the oil is a fraction of that of water though the environmental impact, if a leak occurs, can be much higher.

12thman, your first paragraph is not strictly true. We may not have the Inditherm Plc Heat Pad system in place but we could be using the 'inditherm oil. So long as material specification of the pipework is suitable and the boiler internals suitable for the product there's no reason why we couldn't be using the oil.
