Warmer Kiwis Study: cost-benefit analysis of heat pumps

Mar 14, 2023

Warmer Kiwi Homes is an Energy Efficiency and Conservation Authority (EECA) programme aimed at making homes warmer, drier and healthier. EECA does this by offering grants to owner-occupying homeowners for home insulation and/or an efficient heater.

EECA commissioned Motu Research to investigate the impact of heat pumps installed under the Warmer Kiwi Homes programme. In response, Motu Research set up the Warmer Kiwis Study in 2021.

In this seminar we will report on results from our sample of around 160 homeowners who had received a Warmer Kiwi Homes grant for an energy-efficient heating device. These results relate to:

• people’s health and wellbeing in their homes
• the homes’ indoor environment (including temperature and humidity)
• the outdoor environment from nearby weather stations
• electricity consumption.

 Motu Research’s work concluded that using heat pumps in homes results in warmer and drier living areas through winter, and households save on electricity bills. Overall, the study’s findings show the Warmer Kiwi Homes programme is effective.
