Another reason to buy replacement hot tub covers for Caldera spas is the mildew and mold growth that has developed in your foam cores. As water begins to saturate on your old spa cover, it becomes a perfect environment to invite fungal growth which could contribute to the contamination of your spa’s water. This would explain the foul smell emanating from your spa when it has been covered with a waterlogged hot tub cover. While replacing the foam covers would remedy the problem, It will again, begin to saturate in time. That is why buying a replacement hot tub cover will not only keep your spa or hot tub water warm, it will also keep it away from contamination.
However, if you know that replacement hot tub covers which rely on rigid foam cores for insulation will again, saturate and become prone to mold and mildew growth, why commit the same mistake again? There are hot tub covers which no longer rely on foam cores for insulation. Some of these hot tub covers have air bladders or air pockets to decrease the gap between the water surface and the bottom of the spa cover. This then increases the insulating capacity by not allowing water condensation between the water and the bottom of the spa. And the best part is, they do not have foam cores which will saturate, thus decreasing the R-value and increasing the chances of bacteria and fungi growth.
Apart from the mold and the mildew growth, foam core based replacement hot tub covers for Caldera Spas also tend to become heavy once the water starts to saturate in them. This would make it harder for spa and hot tub owners to remove the spa cover, and may at times become injured for wrestling with heavy, water-logged spa covers. Apart from that, the temperature of the spa or hot-tub water will no longer be maintained with a water-logged hot tub cover as the water starts take over the air spaces. Imagine protecting yourself with a wet blanket when trying to keep yourself warm. Doesn’t work, right?
Still not convinced? Try taking out one of the wet foam core from your old spa cover and cut it open. You will realize that the mildew smell does not come from the water, but from the wet foam core. That is why when you’re considering on purchasing replacement hot tub covers, opt for a hot tub cover which do not rely on foam cores. Not only are they less expensive than the conventional spa and hot tub covers, they’re also more cost efficient and hygienic. You can spare yourself and your family from fungal infection brought by mildew growth in the foam core.
