hot tub settings on Canadian Hot Tub?

Hot tub wooden settings for winter.?
We have a Canadian Hot Tub. We found last year that the cost of running it constantly was through the roof. Since it has a manual timer, but not a digital thermostat, I was wondering if anyone out there has instead of using "freeze protect", just used the timer to come on every 10 minutes or so?

Last night I tried that, and did not change the temp setting (again it's not digital, so it's touchy). It dropped 10 degrees, down to 95.

Would it be cheaper to run the hot tub every ten minutes than all the time, but have the heater come on higher, or would it be cheaper to just leave it on "freeze protect".

I live in Midwestern Ontario, right now temps are -3 to 3 during the day in December. I've heard some sites recommend 15 minutes of run time every hour.

I wrapped the hot tub in bubble wrap insulation, using a solar blanket and a good cover ( not the one that came with the tub, an actual insulated one). All the plumbing is on the outside of the tub, it's not internal.

I think the bubble wrap has an R value of R13 or so. Any ideas? Tips? Tricks? Thanks.

I also insulated the lines with pipe insulation, and around the pump housing as well.
I also added a layer of bubble wrap over top of the cover and a tarp.

Freeze Protect means that the pump is constantly going (not high) but also heating, if I switch it to the timer it is the same thing only I can adjust it so it doesn't run all the time.

Just don't know if it is more economical to have the steady heat and pump running or to allow the timer to go on a few times an hour but at a higher heat to keep the heat as steady as on the freeze protect mode.

I set my Hot tub up outside here in BC on top of 2 inches of the rigid DOW Blue Extruded Polystyrene to prevent the cold coming up from the bottom/ground.

It has a manual timer and I set it to Off for 15 min each hour and low flow/circulate, the jets just cause it to cool off.
I only turn the jets on when I want them but the thermostat is set to 104F where I like it.
See if you can find RadiantGUARD® radiant barrier and bubble insulation.

I've seen it at Rona and Home Depot.

If you spend a couple of hundred insulating you will more than save that much in the first year.

if your tub is out side you can also fill garbage bags with straw or styrofoam peanuts and pile them around it.

You may also find used foil backed fiberglass insulation
(FOIL-FIBERGLASS-VINYL) at a used building supply store.

How much extra should my electricity bill be if I had a Hot tub in the winter?

Q. just wondering how much extra should i expect to pay if i had a hot tub, in the winter time. Hopefully Canadian answers!

Answer
Not Canadian, 2 hours south of the 49th parallel on the west coast.

My Jacuzzi is old, set on economy mode, filters two hours a day, set to only heat during filter cycle. Ths time of year it takes about a half hour in the morning or evening to get up to temp.

Operates at 32 amps when heating. 32 x 240 x 1 hour = 7.7 kw per day, 12 cents per kw, 92 cents per day.
