There is no doubt about it; a hot tub consumes energy. But you can still reduce your environmental impact and your budgetary impact at the same time. Save energy as best you can with your hot tub or spa. Hot tubs are major energy consumers, because they heat and reheat the water on a non-stop basis. But not all spas are created equal and not all hot tub owners use treat their spas the same. Yes, there are things you can do. Here are seven of them.
1) Cover up – no need to keep the hot tub open to the air. Put the hot tub cover on right away, when not in use. This is the same principal as keep your door closed in winter to keep the heat in, or in summer to keep the air conditioning in. Remember when your mother used to admonish you to “Keep the door closed. Are you trying to heat the whole neighbourhood?” Well, the same goes for your hot tub covers – keep the spa covered, or you’ll heat the whole neighbourhood.
2) You don’t need heat while you’re not there…so turn off the heat. Or at least turn it down. In fact, any time you plan to be away from home, any time you know in advance that your schedule will be just too busy to pop in for some relaxation, any time you know it will be several days until the hot tub will be used again, turn he heat down or even off. (NOTE: In winter weather, keep some heat going so that pipes don’t freeze and equipment is not damaged. But you can still turn it way down while you are away for a week or more.
3) You might want also to buy a floating thermal blanket. Very cheap. Very light-weight. Very easy to put on your hot tub. You might consider buying a floating thermal blanket. They are lightweight. They are cheap They are easy to put on your hot tub. It will keep both heat and moisture in the tub and away from your cover. It saves energy and helps your spa cover last longer.
4) Let Mother Nature keep your energy use in check – with a little help from you, of course. A well-placed shrubbery or ornamental fence can also serve as a wind break. Wind blowing across the surface of your hot tub cools it down. A wind break keeps the wind from cooling the water, so you spend less energy heating it back up.
5. Try using a timer. If nobody is in the house during the daytime, and you use the hot tub only during the evening, use a timer to let the hot tub cool several degrees during the day, then reheat automatically for when you need it. You would not want to hot tub to cool too much, because that would actually put a greater strain on your energy bill reheating it each day.
6) Keep your filters well-maintained and clean, and replace them as they show their age. Clogged filters slow down the circulation of water, straining the equipment, and making your motors work harder – and consuming more power. An overworked motor will also have a shorter life and need to be replaced sooner.
7) Don’t waste water. The more water gets splashed around outside the tub, the more new water has to be replaced and reheated. Save water, save heat.
We all love our hot tubs but we also know how much energy they require to keep warm. Keep the fun, let go of (some of) the energy. Make sure the spa accessories you choose actually reduce energy rather than increasing it. These are some common-sense steps you can take to avoid digging too deep into your pockets and scarring too deeply the environment with your hot tub.
