How to tell when Spa heat element needs replacement?

I have an older CalSpa. Its very large (I believe its rated for 6 people). Its all electrics (240 volt). I had a leaking union at the heater so I'm replacing the union. I'm wondering if I should just replace the element while I'm at it. The spa gets up to 104F but if you are in it for an hour or two on a really cold night it will cool down to about 90-95F. I know the electric spas don't warm as fast so I'm not sure if that's normal.

    elec heating elements ether work or they dont .. like light bulb there is no in between.

    but what you can do is buy a higher wattage heating element .

    again like a light bulb. lets say you have a 60 watt bulb and want more light , you buy a 100 watt bulb.

    so may have a low amperage element , if so , buy a higher amperage element .

    look at the one you have and get the numbers off of it and find out if you buy a hotter one. then save this one for a spare.

    it works exactly the same way as a hot water heater does. you can buy diff elements for a hot water heater...
