The sculpture has been displayed at the pool as part of a fundraising campaign to replace the main roof and install solar panels.
Jules Laming, chairwoman of trustees at Jubilee Pool, said the team were “thrilled” to host Helios.
“It is the first time that Helios has ever been hung over a swimming pool anywhere in the world, so this is a world exclusive,” she said.
Jerram added: “It’s also that opportunity in the middle of winter, when it’s so dark and cold outside, to come here and have a swim underneath the sun.
