Getting a new hot tub is always an exciting time but many people get stuck on which hot tub they should choose.
One of the biggest problems people have when choosing a hot tub is knowing the difference between a 13 amp and a 32 amp hot tub.
It is important to know the difference because there are a few key changes between 13 amp and 32 amp hot tubs.
The good news is that at Bluefish Hot Tubs we have decided to list the key differences below to clear up any confusion and make it easier for you, so let’s cover them now!
What is a 13 amp Hot Tub?
13 amp spas are frequently referred to as ‘plug & play’ spas. They’ve grown in popularity in recent years as consumers are preferring a hot tub that does not require a complex electrical setup.
A 13 amp hot tub is called ‘plug and play’ because all it needs is power from a basic three-pin plug. These hot tubs are increasingly popular with consumers trying to save on electrical installations for hot tubs. They also tend to be a convenient upgrade from an inflatable hot tub as you can use the same electrical supply.
What is a 32 amp hot tub?
A 32 amp hot tub is a hot tub that is configured for a 32 amp electrical supply. It cannot be powered with a standard three-pin plug found in the home. Why would you choose a hot tub with a more complicated supply? There can be benefits to it, mostly around the power of the pumps and being able to run the heater and pumps at the same time.
What is the difference between a 13 amp and 32 amp hot tub?
As we’ve mentioned before it’s important to know about the key differences between 13 amp and 32 amp hot tubs. Below we have outlined a few of the key differences so you will have a better idea of what each offers.
1. 13 amp spas are 'Plug and Play'
To provide you with more flexible options on how you would like to use your spa, 13 amp spas are fitted with a ‘plug and play’ element. This allows you to simply unplug the spa, allow it to drain, and then move it to a new spot or a new home without the need to get a certified electrician to detach the electrics. Many customers find that this is a much more straightforward solution for them.
Even with the ‘plug and play,’ element, you should be careful about where you plug in your 13 amp hot tub. For example, you shouldn’t plug in a 13 amp hot tub through a basic extension cable running from indoor sockets, as extension cables that aren’t secured by steel wire armour and RCDs can be incredibly hazardous – particularly where water is present.
2. Cost of setting up the 32 amp electrical supply
A 32 amp hot tub requires a 32 amp supply with an isolator switch. If you do not currently have one of these in your garden, you’ll need to have one installed to have a 32 amp spa.
A 13 amp spa can run through a basic waterproof RCD-protected three-pronged outdoor socket, shaving a couple of hundred pounds off the upfront expense of the hot tub.
It typically costs around £150-£450 to have a socket set up for a 13 amp spa and up to £750 to have a 32 amp feed installed.
3. The power supply is different
Another different between 13 amp and 32 amp hot tubs is the power supply that is required.
While 13 amp models run on your basic three-pin plug, 32 amp hot tubs require a 32 amp electrical supply to be set up.
The 13 amp hot tubs can be used by simply setting them up yourself, however, the 32 amp hot tubs are different. If you want to use a 32 amp hot tub then to satisfy building regulations you’ll need a certified electrician to set up an electrical supply and run an armoured cable to your 32 amp hot tub for you.
You should be aware that by doing this you will raise the installation cost by a couple of hundred pounds however you will have a higher amperage hot tub fitted properly.
4. 13 amp spas will only run the pump or heater at any one time
Another difference between the 13 amp setup and the 32 amp setup is that a 13 amp hot tub doesn’t have the correct amount of power to run its heater and jets simultaneously.
On a mild or warm day, this isn’t a big deal. However, on a cold day, if the heater does not run together with the pumps, there is the risk that the hot tub could drop temperature rather quickly when in use. This is because hot tubs lose around 60% of their heat through the surface of the water so they can cool off rather rapidly without the aid of a heater.
To prevent this from happening and reduce heat loss, you should have a well-insulated hot tub, so if you’d prefer a 13 amp configuration, be sure to view our award-winning R10 range, and you won’t notice this difference as much.
Should I choose a 13 amp or 32 amp supply?
At Bluefish Hot Tubs we always work hard to make sure you aren’t stuck for choice, so whether you are after a 13 amp or 32 amp hot tub, you will have a wide selection.
We would recommend that if you’re considering getting a 13 amp hot tub, don’t get an inflatable one. Often times they may seem like a cheap alternative however they never come close to the real thing.
So Instead, get one from Bluefish Hot Tubs, not only will it be higher quality, but it will also cost you less in the long run.
On the other hand, if you want your spa to run both the pumps and heaters at the same time, then a 32 amp design may be the best option for you.
Although you should be aware that the 32amp electrical supply is a little more complicated, if you want to avoid this then 13 amp is a better choice. Especially when you consider that installing a 13-amp hot tub will cost a few hundred pounds less than a higher amperage version.
Whether the 13 amp or a 32 amp configuration is the right option for you, make sure to get yours from a dealer with a great reputation like Bluefish Hot Tubs, so you know you’re getting an industry-leading hot tub at an affordable price.
