Problems with Full / Partial Foam Hot Tub Insulation

Problems with Full / Partial Foam Hot Tub Insulation

One of the most important features when buying a hot tub is the insulation and energy efficiency of the hot tub. Although, a lot of people pay attention to this feature, few look into the type of insulation inside the hot tub. Why is this important? Here are a few points of comparaison and problems associated with Full Foam and Partial  / Perimeter Foam insulation and why Thermal Shield insulation is better.

FULL FOAM

  • Water will take the path of least resistance hence, if there was a problem with the plumbing the water could appear on the other side
  • It is difficult to service because there is no access to plumbing without a full dig out
  • Not able to access plumbing without compromising the insulation or structural integrity
  • Each motor creates 1.5 kw of heat and all of that heat was being expelled from the hot tub as opposed to being used to help heat the water
Despite improvements in technology and materials, most Hot Tub manufacturers continue to use dated full foam technology to insulate their hot tubs.
 
PARTIAL FOAM / PERIMETER FOAM
  • Causes leaks due to plumbing support issues
  • Gaps in panels allow heat to escape
  • The Motor needs to breath, and without vents it overheats and causes the pumps to fail
 
THERMAL SHIELD TECHNOLOGY
 

Polyfilm barrier supports the plumbing

Easy access to service

Uses the waste heat of the motor, shell and pipes to heat the hot tub

Allow for Eco heat exchange Venting to expel the heat in the summer and trap the heat in the winter
