Several months after this heat pump at a prestigious private school was opened for inspection, it turned out to be spotlessly clean and free of any scale build-up.

The local contractor puts it down to one thing: the PTH. In this case, all it took was one PTH50 installed inline in front of the vulnerable piece of equipment.


The result is evident from the photographs on the right: PTH offers full protection against limescale build-up for this heat pump.
