Heat Pump Heroes: Hosting a Water-Saving Heat Pump Challenge

Host a group workshop about water-heating carbon calculations, flow rates, and a Shower Sprint Challenge – all designed to encourage the heat pump water heater transition.

In Mission 5 of Earth Doctors, participants investigate where our water comes from, how it gets to our homes, and how much energy it takes to heat the water we use every day.

Through hands-on calculations and experiments, participants measure water flow rates, calculate the energy and carbon impact of hot water, and discover how small changes to everyday routines can add up to meaningful savings. The worksheet includes calculating the emissions required for heat pumps hot water heats vs fossil fuel sources.

The mission culminates in a Shower Sprint Challenge—a practical experiment to see how much water, energy, and carbon can be saved by taking a faster shower.

You'll explore:

• Where our household water comes from and how it reaches us
• The connection between water use, energy, and carbon emissions
• How to measure and compare water flow rates
• How to calculate the energy required to heat water
• How everyday actions can reduce water and energy use
• How to run your own Shower Sprint Challenge

Comes with:

• An educational slideshow
• Downloadable worksheets
• Hands-on calculations and activities
• Instructions for running the Shower Sprint Challenge

Earth Doctors Series Workshops are designed for parents, teachers, and community educators who want to host more hands-on, action-oriented environmental workshops in classrooms and community groups.
