leaves and other items to collect on. It does not help one way or another with energy efficiency.
Another thing to consider is the cover skirt/flap, you will want this to hang STRAIGHT DOWN. So, if the lip of the spa is at an angle, make sure you measure the cover long enough to achieve this. You don't want the skirt sticking out by measuring your cover too short. Also, measure the skirt (3" is standard) long enough to cover the spa lip, or the spa cabinet rim. (See figure above)
It is always better to make the cover size a little bit bigger than your spa when measuring. If you make a mistake, and measure too small, the cover will not fit properly, will not sit flat and will not hold the heat in. |
