Unbiased Kiwi Heating Data
We buy every portable heater retail, stripping them down in our Dunedin lab to measure real-world power draw and thermal output in uninsulated homes.

We never accept free review units from manufacturers. Every device tested is bought anonymously at retail to ensure we test the exact same hardware you buy.
We measure real-world power draw with inline electricity meters and map heat distribution using high-resolution thermal imaging cameras.
Our site carries no kickbacks, no tracking tokens, and no sponsored placements. We are funded entirely by reader donations and clean consumer advocacy.
Tested in cold rooms
To get true performance metrics, we test heaters inside uninsulated Dunedin villas during winter. We measure how long it takes to raise ambient temperature by five degrees and calculate the exact NZD running costs.
