Cut Spa Heating Costs with this One Weird Tip!
OK, I don't know if you've seen those adsense ads that promise Lose belly fat with this one weird tip! They seem to be following me around, but I like my belly just the way it is, thank you.
It's become sort of a meme, this "one weird tip" idea - it makes me chuckle just a bit, so I had to use it in the title.
The problem with One Weird Tip blog posts, is that they tend to be rather short. There is, after all, only one tip.
Cut Hot Tub Heating Costs ...with this one weird tip!
Insulate your Spa!
Huh? Add home insulation underneath your spa, to seal up air gaps and hold the heat in your spa!
It's an inexpensive way to add more R-value to your spa or hot tub. And it's so easy to install, just tack it to the inside of the cabinet, lay it on the ground, tape it to the spa shell or just stuff it in there! Just keep it away from your spa pak and other equipment.
How much you need depends on how cold your climate is. If you live in southern California, like me, very little is needed, but if your spa is up north, you'll need more.
Home Insulation is sold at every home store and hardware so it's easy to obtain for a good price. The selection is absolutely dizzying, sold in many different sizes, in rolls or 'bats', and in several R-value ratings, from R-13 (shown) up to R-38.
Even one roll of the cheapest, lowest R-value insulation will increase your spa efficiency! Most heat loss on a spa is out of the sides and bottom, while covered with a good spa cover, of course.
If you buy the fiberglass insulation, it comes faced (with a paper backing) or unfaced. Unfaced can make you itch like crazy if you aren't wearing long sleeves and gloves. You could also use rigid insulation, those pink boards, to line the inside of your spa cabinet. Or, you could buy a spray foam kit, and spray every nook and cranny with expanding foam. Some stores carry insulation made from denim, or recycled textiles, if you want to use a natural insulation product.
For those of you with a fully foamed spa, where spray foam was injected to completely encase the spa shell in foam, I suppose my one weird tip is not much use. So here's another weird tip, just for you! Use a floating foam spa blanket, to reduce evaporation and heat loss by creating another barrier between the water and the spa cover.
