No Foam Filled
On a ‘foam-filled’ or ‘foam backed’ spa, all the waste heat from the pumps is expelled out. Therefore, there is no transference through the foam to the spa water. This means that the spa heater has to be on far more often, causing higher electricity costs and heater wear and tear.
Many spa manufacturers assume price, not quality, is the deciding factor when buying a Hot Tub, and so manufacture their spas accordingly. The phrase ‘you get what you pay for’ definitely applies here. All brands stocked at The Hot Tub & SwimSpa Centre have the Heatlock System. This is why they are proven to be the cheapest and greenest Hot Tubs available on today market.
