What's the difference between Bromic Tungsten & Platinum Heaters?

There are a number of differences - they differ in their designs.

While the Tungsten collection features a honeycomb mesh in front of the heat panels, the Platinum series is covered by a ceramic glass screen that is encased in a stainless-steel frame.

The electric heaters in the collections also differ in the heat output. Tungsten series heaters come in 2000, 3000, 4000 and 6000W, while Platinum Electric heaters are available in 2300 and 3400W.
