Not all spa pools are built the same and insulation is the difference you’ll feel on your power bill.

In this test, we compare 4 common types of spa insulation:
1. No insulation
2. Foil perimeter
3. Spray-on shell
4. Edge-to-Edge Full Foam

We poured hot water into each setup and returned later to measure heat retention. The results prove why Hot Spring Spas use edge-to-edge full foam insulation to deliver leading energy efficiency and lower running costs for spa owners in New Zealand and Australia.

If you’re researching spa pools and wondering which option is best for your backyard, here’s what you need to know:
✅ Why insulation impacts spa pool running costs
✅ How better insulation means warmer water for longer
✅ The key to choosing an energy-efficient spa pool in NZ & Australia
