HOT TUB INSULATION & STRUCTURE EFFECTIVE INSULATION IS EXTREMELY IMPORTANT FOR HOT TUBS IN ORDER TO REDUCE RUNNING COSTS TO A MINIMUM. THE TRIPLE “REFLECTIVE THERMAL BARRIER” (RTB) INSULATION OF WELLIS SPAS UTILIZES THERMAL GAINS FROM THE SPA’S EQUIPMENT, COLLECTING ANY WASTE HEAT ENERGY AND REFLECTING IT BACK INTO THE PLUMBING AND SHELL, WHILST KEEPING OUT THE COLDER OUTER AIR. We’ve even built our RTB system into our Thermal Spa covers which also have a special reflective foil coating beneath them to bounce rising heat back into the spa water. This integrated energy management system means Wellis Spas are exceptionally economical to own. Many spa manufacturers still use discredited spray foam insulation whilst, a few still mount the spa equipment, actually outside the spa cabinet, beneath the steps. These old legacy systems are both outdated as well as expensive to run and damaging to our environment. The spa heatmap picture is an infrared image of a Wellis spa which shows the efficiency of the RTB system. The persons face is red, indicating a high heat loss, whilst the pastel green and blues of the Wellis spa indicate a very low heat loss as almost all the heat is kept inside the spa and cabinet.

THE WELLIS SPA PRODUCED EXCELLENT RESULTS IN THE HEATMAP TEST The temperature of the water in the spa visible in the picture is 35 °C, while that of the outer covering and the thermal cover is merely 4 °C. The outdoor temperature is -5 °C.

SCANDINAVIAN INSULATION - OPTION For extreme climates we offer the option of our “Scandinavian” insulation. This has a much higher insulation rating with triple layer Polyfoam panels and additional under spa rim and floor pan insulation. Only recommended for extreme sub zero temperatures and not for more temperate climates. 1. 2. 3.
