Where does the insulation go in a hot spring?
The insulation is placed on the outer wall of the spa shell. This insulation may be rigid foam boards (which can become brittle over time) or sprayed-in foam, and can add some structural strength to the spa and components. Inside the inner wall of the spa shell is a layer of air.
Is it necessary to put insulation on Spa shell?
Some companies claim that insulation on the shell is not necessary. This claim is refuted by 99.99% of spa manufacturers as this form of insulation is in fact the most important way to stop heat loss. The size of the gap between the shell and cabinet is also important as hot air escapes and cold air can enter through this gap.
Do you need insulation for outdoor spa bath?
If you want to understand how efficient a front yard or backyard outdoor spa bath is, look at the amount of and/or number of layers of insulation on the shell, the inside of the cabinet panels and the base. Some companies claim that insulation on the shell is not necessary.
Why is insulation important in a hot tub?
Insulation is a key factor differentiating hot tubs of various quality levels. Better insulation reduces the amount of work your spa has to do to heat the water and keep it hot. Water that stays hot not only increases owner enjoyment it also lowers energy use – and therefore your utility bill.
Which is the best way to insulate a spa?
In theory – the better the insulation, the lower the running costs. There are three main ways spas are insulated – each with their own pros and cons. In colder climates, spas and swim spas lose heat from their water, requiring the heater to turn on to hold the spa at the preset temperature.
What happens if there is no insulation in a hot tub?
Spas with no hot tub insulation will result in higher energy cost, as well as potential problems with shell cracks as there is no support. This hot tub insulation practice consists of an insulation blanket being wrapped along the lining of the shell and/or inside exterior walls. There is a large void of space that is exposed.
When do you remove insulation from a spa?
Unlike full foam, if the spa requires repair, the insulation is removed when the cabinet is removed giving unobstructed access to plumbing and equipment. This significantly reduces the costs of repairs and the lifetime cost of owning a spa.
Is the insulation on the inside or outside of the pool?
Because the insulation is on the inside of the cabinet, like full foam, both the water within the shell and also within the plumbing is insulated. Unlike full foam, if the spa requires repair, the insulation is removed when the cabinet is removed giving unobstructed access to plumbing and equipment.
