Do you need planning permission to install a hot tub? Planning permission is not normally required for items of a relocatable/temporary nature like a hot tub or swim spa, however, if you live in an area of outstanding natural beauty, or listed property or a conservation area you would do well to seek advice from the planners before installing your pool or spa.
What do you need to prepare before installing a hot tub? To install your hot tub, you only need to worry about three things: a solid, level base to stand it on, a power outlet to provide the juice, and a hose pipe to fill it up with - it really is that simple. If you plan to sink the spa, there will be the added consideration of access to the component door for servicing, so do bear that in mind when planning and preparing your base. Always get full installation instructions from your supplier, which should include specific advice on sinking the model purchased.
How do you actually move and install the hot tub? Most hot tubs are very heavy and easily damaged, so if you intend to move one make sure you have plenty of help and good dollies/trailers to help move the spa. It is usual to put a hot tub on its side for moving, but take care not to put it on the pumps side as the door on most hot tubs is very weak (some hot tubs have to be transported flat). Note: Hire a trailer or flat bed to drive from one address to another, most hot tubs will not fit in a luton or a transit van. If in doubt call in a hot tub company who will be expert in moving spas and insured.
How long should it take a hot tub to get hot? Firstly, we must remember hot tub heaters vary considerably, from 1KW up to 6KW, and the volume of water to be heated varies, as does the mains water temperature from summer to winter. As an example, let's look at a 300 gallon hot tub with a 1.5kW heater, with summer temperature mains water. You should expect this to be hot in about 20 hours. Bigger spas, different heaters and winter mains water will all have longer or shorter heating times. A final point - hot tubs are designed to be hot 24/7. Once a hot tub is hot you are only ever topping up lost heat. A 1.5KW heater will put about 3 degrees of heat into a spa per hour, so a typical 1/2 hour use will drop the spa temperature about 1 degree, meaning it will take about 20 minutes to recover.
Is it more efficient to keep your hot tub hot, or heat it up for each use? If your use pattern is to use your spa most nights, then provided your spa has been made with a good cover and quality insulation, it is best to keep the spa hot. This way, your heater will cut in and out as it needs to, and in summer may hardly come on at all. If your use pattern is less often, and/or your spa is not insulated to a very high standard, then you are much better off turning it off between use. Note: In the winter, because of the risk of freeze damage if the spa is not being heated, it should be completely drained if you are switching the heat off.
Can you run a hot tub cold? No problem, but why you would want to do so is beyond us
How long should you stay in your hot tub? There is no recommended time limit for bathing in your hot tub, however, it is best to keep yourself hydrated whilst you are in the spa and drink plenty of water. You should also take care to maintain your sanitizer level, which will deplete over a few hours of bathing.
Are hot tubs good for your skin? Water is good for your skin, but hot water over a long period will cause your skin to dry out. It is important to maintain the correct pH and Sanitizer balance so as not to cause skin irritation. I would always suggest that a good moisturiser is used all over after using your hot tub.
How do you drain a hot tub? Many hot tubs have bottom drains which you connect to a hose pipe and run to a drain. However if you have not got a bottom drain then this is not a big problem as you can purchase a submersible pump and roll flat hose and can drain the spa that way just as easily.
What is an air lock in a hot tub? Air locks happen when the hot tub is being filled with water. It is possible for both ends of a plumbing system to simultaneously fill up with water at both the suction end and the return end which sometimes leaves an air lock in the plumbing. This can cause both heater and pump problems. To overcome this issue it is suggested to push the hose pipe down into where your filters screw in which will purge all the air out of your important heating and circulation systems.
