Potterton Prima

This page is a brief side-note about the Potterton Prima, which is very closely related to the Potterton Profile. The Prima looks identical to the profile externally and shares all the same controls and electronics. It is so very similar to the Profile aesthetically but has one big difference technically. 

Although this is just a guess, the Prima was probably designed, produced and marketed following the emergence of data showing that positive gas pressure boilers such as the Profile are slightly less ‘safe’ than negative case pressure boilers. This is due to the remarkable ability of gas technicians to incorrectly replace the front cover leaving leaks, thus rendering a positive gas pressure dangerous to use. With a negative case pressure boiler an incorrectly fitted front cover does not make it dangerous, so this is an advance in safety. The Prima is a negative case pressure boiler unlike the Profile, which is positive case pressure appliance.

For fault-tracing a Prima, all my comments on the Potterton Profile page on this site apply.
