If it freezes solid, just give up and throw it out in the spring.
or bring in a Hiab equipped tanker truck of single malt.

With a 2000L hot tub when it gets really cold, I need about 12 to 16 kWh per day to keep it at temp. That was with a waterlogged 3-2" cover. Hopefully new 6-4" cover cuts that back a bit.Here are my impressions so far.
We have a 7’ X 7’ tub with seating for 7.
We did a 220 V tub and it has 42 jets.
It’s been mild out so, keep it at temp has been easy. Will have to see how much it works as temps drop in the winter.
While it’s generally my wife and I or just myself, we have a couple of teenagers that jump in occasionally. 4 is nice. Any more and it wouldn’t be enjoyable.
Having seating for 7 give you choices for the various jet layout for each seat. I have about 3 spots I like to switch around.
We don’t use the lighting very often as enjoy the natural light of the evening or morning etc.
I wouldn’t bother with a 110 V set up. I would imagine as outside temps drop and the jets on, you’ll want the heater to maintain the tub temp.

With an inflatable 120V tub, I expect the heater would run all the time in the winter.
Yes, power consumption is unaffected by voltage. I was figuring the 120v tub is often inflatable and therefore less insulated. If it has a 1kW heater, that should put the heater on almost full time. 220v let's you schedule heat off-peak (which we dont have right now).A buddy is a mechanic and needs his tub to relieve the aches and stresses of the day.
If a couple of bucks a day in hydro keeps someone from taking a bunch of pills I think they're ahead.
The power consumption should be about the same whether it's 120 or 240. The higher voltage typically means more power which means a faster temperature recovery. If the tub wasn't going to be used for a while the setting could be reduced but brought back in a reasonable time. You couldn't do that with a low power system so it's 24/7.
I did an experiment on a high output floor warming system that showed a potential 75% savings in power consumption but there was a potential safety risk.
That's true however in most cases 220v will be slightly cheaper to operate over time as the resistance losses in the power line feeding the pump/heater will be slightly lower at 220v.Yes, power consumption is unaffected by voltage.

I tried to buy a replacement lid with extruded foam. No bueno. I could not find anyone that would sell it (since there are only two cover manufacturers in canada I wasn't that surprised). I thought about making my own inserts but that sucks too as making rigid 4x8 panels out of 2x4 panels is not easy nor cheap and I was not having luck finding someone to sell me larger sheets.the new tubs also incorporate using the heat generated by the pump motor as part of the heating circuit, and the overall quality of the foam insulation has gotten better, lids with extruded foam (SM type) as opposed to the discount white bead board foam lower cost units used.
There is something to be said for a new tub if you can swing it.
Not a bad plan. I will see what I can find again next time. It looks like extruded would cost me ~$520+tax for the foam only. Then need to add adhesive + hotwire + cover. The whole cover with white foam was similar to the SM material cost without all of the required extras.If you hunt around, auto/boat upholstery guys often will make a hot tub lid, they will use whatever foam you like. You can make bigger sheets of SM type foam by laminating , you just stagger the seams and glue it together like a wooden building block using foam safe adhesive in a caulking gun tube.
I used to make up big blocks of foam then shave them to shape to make plugs for molds for fiberglass work.
Why Extruded? XPS is less expensive and absorbs up to .03% moisture, EPS will absorb water -- up to 4%, adding 40-50lbs to the weight of your lid over time. Also, EPS twists and bends (look at a few boards net time you visit a Home Depot) XPS is pretty stable.Not a bad plan. I will see what I can find again next time.

@Zoodles95 good idea. However one thing I’ve always heard about the 110V option is that they take 8-10hrs to heat up and then in the winter never actually do because the heaters can’t keep up.
Not sure if there are better options now than what my friends have though.

I am still trying to pull a rabbit out of my hat (or rear end) before the winter hits. Trying to sell off some of my toys to raise some funds to buy a used tub and build a base.
Found this on kijjij. A company that builds a pad by making a base with railway ties and filling with gravel and topping with pavers. Considering that I just reagravated my tennis elbow it would be nice to have someone else build this instead of me digging down 6 inches, putting in gravel, getting it level, and putting the ABS system in I showed earlier.
Just wondering if anyone else has tried this solution or something similar?
I'm a victim of marketing hype.
I did have a new cover made for my last one by a guy that worked for AppleAutoGlass , now defunct , we used styrofoam SM in the insulation, 6" thick. It was three yrs old when I moved and didnt weigh a ton yet.
As your here as in house expert, does anybody make a small (just two people + leg room) tub that would fit through a 34" doorway? Its that or a crane.
