Heat pumps reduce Go Media Stadium’s emissions and costs

The installation of brand-new electric heat pumps in the East and West Stands at Go Media Stadium will help the venue transition away from using gas. 

State-of-the-art electric heat pumps have replaced legacy gas boilers in both stands and will be used to heat water for showers and kitchens. 

The ultra-efficient heat pumps use carbon dioxide as a refrigerant and take heat from the air to heat up water to over 60 degrees.  The heat pumps are 400% efficient compared to a gas fired boiler which is typically only 85% efficient.  Essentially this means that for every 1 kilowatt of electricity they consume, they generate over 4 kilowatts of heat energy. 

Reducing emissions and costs 

The gas boilers at Go Media Stadium were nearing the end of their useful life. The switch from gas boilers to using efficient electrical equipment reduces the Stadium’s ongoing carbon emissions as well as utility costs.  

While the exact emissions reductions are still being verified, the installation of the heat pumps is estimated to contribute to over 100 tonnes of emissions reductions. 

For reference, 100 tonnes of emissions reductions is equivalent to 5,000 trees growing for a year. 

Auckland Stadiums Acting-Director Scott Couch said, “The new heat pumps are a fantastic addition to Go Media Stadium and will make a huge difference. Adding cutting edge tech to a legacy venue likes this reduces operational costs and cuts our emissions which is a win for us, our hirers and the people of Tāmaki Makaurau. We are on a mission to make Go Media Stadium the most sustainable venue in New Zealand and this is a fantastic step in that journey.” 

A greener Auckland 

This project is part of a transition away from burning fossil fuels at all Tātaki Auckland Unlimited’s sites to reduce our greenhouse gas emissions and lessen our impact on the environment.
