Heat Guard™ 4.5mm Thermal Pool Blanket

Premium Thermal Pool Covers NZ

Hold the Heat. Reduce Running Costs. Swim Longer.

A heated pool is only as efficient as its ability to hold onto the heat.

Whether your pool is heated by solar heating, a heat pump or gas, the biggest cause of heat loss isn’t through the walls—it’s evaporation from the water’s surface.

The PSH Heat Guard™ 4.5mm Thermal Blanket dramatically reduces evaporation while helping retain valuable heat, keeping your pool warmer for longer and reducing ongoing heating costs.


Why Every Heated Pool Needs a Thermal Blanket

Without a pool cover your pool loses heat every day through:

  • Evaporation
  • Wind
  • Night-time cooling
  • Cooler air temperatures

A thermal blanket creates an insulating layer over the water while dramatically reducing evaporation—the largest contributor to swimming pool heat loss.

That means:

✓ Lower heating costs

✓ Longer swimming season

✓ Less water evaporation

✓ Reduced chemical consumption

✓ Cleaner pool

✓ Less debris

✓ Less pump runtime


Why Choose Heat Guard™?

Unlike traditional bubble covers, Heat Guard™ uses premium closed-cell thermal foam designed to maximise heat retention while offering excellent durability.

Benefits include:

  • Approximately 4.5mm thick premium thermal construction
  • Closed-cell insulation technology
  • UV stabilised
  • Extremely durable
  • Custom manufactured
  • Suitable for new and existing pools
  • Compatible with hidden rollers
  • Compatible with automatic cover systems
  • Designed for New Zealand conditions

Built for Solar Heating

Solar heating works by collecting free heat from your roof and transferring it directly into your swimming pool.

Your Heat Guard™ blanket helps hold that heat overnight, allowing your solar system to work more effectively throughout the swimming season.

Together they create one of the lowest running-cost pool heating systems available.

Heat Pump Owners

Heat pumps use electricity to produce heat.

A thermal blanket helps reduce heat loss so the heat pump doesn’t have to keep replacing heat lost through evaporation.

Less heat loss means:

  • shorter heating cycles
  • reduced electricity consumption
  • lower running costs
  • improved heating performance
