How long does it take to heat up my Lay Z Spa?

This can vary greatly depending on the temperature of fresh water that goes into the hot tub, the ambient air temperature and which Lay‑Z‑Spa model you have. The higher the capacity of water, the longer the hot tub will take to heat up.

The Lay‑Z‑Spa Pump heats the water via a circulating pump and heats up at approx. 1.5‑2°C/h (3‑4°F/h) per hour. In England in the Summer, it can take on average 6 ‑ 12 hours. Ensuring that the hot tub is well insulated and that the lid is on will also greatly help!

Here is a guide of the approximate time it takes to heat based on the water and ambient temperature
