People contacting me for advice about their Netaheat often have difficulty working out exactly which model they have. I need to know the model before I can give any meaningful advice as each of the four versions works in different ways. So, here are some photos to compare with yours.
Firstly, the rarest version of all is a Netaheat ‘Original’, and unsurprisingly I can’t find a photo of one to show you. It looks superficially the same as the MkII and MkIIF in the section below, but without “MkII” or MkIIF” printed on the lower cover. The labelling on the lower brown and silver metal cover just says “Netaheat 10-16” or “Netaheat 16-22”. Nothing else.
Here is a close-up of the control panel showing the model and size labels. The model label is on the left, identifying the Netaheat as a Mk II. The size label stating “Netaheat 10-16” in this case, is on the right and identifies this Netaheat as a size 10-16.
This is a Netaheat Electronic. Not a great photo, this one is showing the classic heat-darkening of the front panel for which the Netaheat Electronic is well-known. (The front panel gets very hot when the boiler is running.)
And here is a close-up view showing where to find the boiler size and the model, in this case an Electronic 16-22. There is a tinted perspex sliding panel on the Electronic model which slides to the left and covers the control knob. Not that easy to see in photos.
