Here's a photo of an old PureFreedom 5.2kw heater.
I'm sure its been redesigned since then as there is an awful waste of space inside the unit.
But you can see how it works quite easily.
I've messed with the brightness so you can see the hose detail better.
Here's the original
BTW. The heater is attached to a separate stand that PF also sell to order.
Wow. I've just noticed after all these years that I've had this photo that the heat exchanger is connected up incorrectly.
The recommended flows through the heat exchanger is supposed to be opposite and not in the same direction as per the photo. The heat exchanger is less efficient this way, unless of course PF did this purposely.
