How the Trust's ground source heat pumps work, and what they do for the planet, explained in animation.

Birmingham Women’s and Children’s NHS Foundation Trust is doing its bit for the planet by installing ground source heat pumps. We worked closely with the Trust on an animation that explains exactly how they work and the benefits they provide.

The making of Heat Pump Animation

Progress sketches

Four early sketches of the round blue water droplet characters, two smaller and two larger, each with a different smiling face

Character development

Rendered 3D models of the characters: two blue water droplets at the top and a pale pink and a purple refrigerant sphere below, shown twice with different expressions

Graphic applications

Flat illustrated versions of the characters in a textured hand-drawn style: a small and a large blue water droplet on the left, a large and a small pink refrigerant sphere on the right

Opening shot

A tall pencil and marker sketch of the opening shot, the camera travelling down from the hospital through layers of grass, soil and rock to the water below, with frames marked 1B, 1D, 1E and 1G, next to four rendered frames of the same journey
