Title: Example of real-world electrical cost
Post by: zroger73 on October 13, 2009, 11:48:56 am
12 months prior to installing my 2008 HotSpring Sovereign II, I used 11,733 KWH. 12 months following installation, I used 13,937 KWH - an increase of 2,164 KWH. Based on the last 36 months, my electricity cost averaged $0.08/KWH.

So, the real-world data is...

I use my hot tub about 45-60 minutes 2 or 3 times per week - more during the winter, less during the summer. Considering this data, my hot tub has increased my electric bill an average of $14.10 per month here in Northeast Texas.

If you don't mind I will print that post.
We will hook up a meter to the 110V models to show customers how little HotSpring Spas cost to run.
Having testimonials helps a lot also.

Here's wishing you many happy decades of soaking in your HotSpring! Mine is a 1991 Classic.

I don't mind at all. I also elaborated a bit more on a similar post over at poolspaforum.com by stating that part of that increase may also be due to a hotter summer, colder winter, or lifestyle changes, but I'm confident that number is pretty close to reality.

Nothing against HS but just about all the top brands will be the same. HS does not an advantage over the industry on electrical usage.

I disagree...Sorry - maybe some top brands. We've sold Sundance, Jacuzzi, Caldera & HotSpring. As far as those brands are concerned IMO HotSpring is considerably more efficient.

Those numbers fall right about in line with our Bullfrog, so I have to agree with Gary that most of the better tubs out there will use roughly the same amount of electricity

OK, wait...So Canada you are saying your tub in Canada is using the same electric as a tub in Texas?  While none of this proves anything since we have none of the parameters...Just the difference in winter temperatures make me wonder.... :-\  Is the conclusion of this data collection that a Hot Springs tub in Texas is as efficient as a Bull Frog in Canada???

That comes across as a tad bit rude and offensive to me, but maybe it's because I haven't had my coffee yet this morning. :)

Just curious about your winter temperatures, Zroger....I don't think Jim meant anything by his comment..maybe just that your numbers look great, but  there really isn't any standard test that WE can use to compare brands and efficiency. Maybe someone can...but I don't think we can. So your numbers are great and you should be very pleased.

I have had success running my tub in economy mode all winter long and will plan on doing that this winter as well....as long as we don't slide into a deep freeze.  :o I know my tub is more expensive to run because my electric costs are almost double what yours are per KWH!

I find it interesting though that Canada gets similar results in the cold of Canadian winters.  ;)

Unless you separate out the spa from everything else and meter it on its own there is no way to be exact about what the spa is costing you but what you've shown is a good indicator and your spa is well insulated so there's no surprise. Keep enjoying!

I completely understand that it's not a perfect number and is why I further elaborated that there could be other factors as well. I didn't express an opinion as to whether my results appeared "cheap" or "expensive". I have a gas furnace, so the majority of my electricity is consumed by cooling, drying clothes, cooking, and the typical assortment of electrical appliances - factors that in retrospect had little, if any, changes to their normal usage patterns during the two-year period I analyzed (except for the hot tub). I haven't downloaded recorded historical climate data to determine what temperature differences existed between the pre-spa period and the post-spa period, but the average temperatures during those two periods were close enough. The primary purpose of my post was to give a new potential spa owner or curious existing owner an idea about what to expect in their utility bill if they live in Northeast Texas or a similar climate. :)

Boni

  I sat down after the first year of tub ownership and figured out the average increase during the first year.  The winter months our tub was higher then that but the average was about $16.

I have no idea about the difference in cost per kilowatt between Ontario and Texas but I will say I have been very happy with the energy efficiency of our tub.

  Also keep in mind I am in Southern Ontario  essentially Detroit so its not like I live in Cold Lake Alberta :D

I have relatives in Detroit. It's colder than heck there in the winter. I'm sure chas and brook can back me up on this :-)

One thing people frequently overlook, is things they've done to generally REDUCE their overall electric costs. I remember one guy the got rid of the extra refrigerator in his garage about te same time he got the spa. Thought the spa was only costing him abut $25 a month...he didn't take into consideration that the beat up old fridge could have been costing as much as $75 a month. So, while his monthly bill may have only increased $25, the spa was actually running $100.

And there's a lots more than just old refrigerators...Kids going to collage, or leaving home, replacing some older or not so old appliance(s) )that you may not even had consider to be energy hogs)

  Didn't mean to offend and I was in a hurry,so sorry!  :)  There is just so many more variables to look at and consider.  I have no doubt the HS spa is efficient but not much more than a lot of other quality spas out there.

Oh Doc,  You just reminded me of my big electric HOG...and he is at college now. My son used to sit under the hair dryer for about 15 minutes drying his hair and his body every morning before school.  Bet that's enough electric to pay for my tub..haha

That's just it Doc.

  I figured out the cost over that first year because the tub was our major purchase for that year.  Nothing else changed at all, the only difference was the tub and maybe some new CFL light bulbs

I think it is pretty accurate

Now I think Brooke mentioned almost moving to Canada at one point, but I'm sure Chas thinks everything below 50 degrees is cold. :D

The average temperature where I'm at in Texas I believe is 66 degrees. Winters normally get down into the 30s at night and Summers usually 90s to 100s. Depending on whether my body is running hot or cold, I usually find anything below 60 to 70 to be "too cold". I have no upper temperature limit. The only snow I usually see is on TV. I'd never make it up North. ;)

Whatever ZRoger stated obviously isn't meant to be a statment about Bullfrog, Jacuzzi or any other full foam spa as he's just stating what he's seeing. In reality all full foam spas are not necessarily insulated equally and Hot Springs will do better than most full foamers because it uses multiple density foams in a layering fashion whereas most full foams are filled with just lighter (˝#) density foam but in the end all full foam spas should insulate well.

It would be nice if some day spas incorporated energy meters in their controls so you could go to your screen and see what you're using.

I would like to use a data logger to record ambient temperature, water temperature, and energy consumption, then use this data to calculate actual heat loss. I have access to this equipment at my job, but I don't think they would appreciate it if I borrowed the stuff for 12 months.  ;D

Same here Roger, my 12 month average was a very crude measurement.  Actually it was comparing one month usage to the same period one year prior.  Hardly exact but like I said I am pleasantly surprised by my tubs power usage


For what it's worth you have to travel up north to see snow at least once in your life.  My wife's best friends daughter who was born and raised in Florida saw snow for the first time last year.  She was amazed and LOVED it, she turned into a suicidal maniac on a toboggan :D

2 shout-outs in one post it feels like I never left!!!!  :-)

I have no idea what my tub costs me to run... but I'll tell ya my old house vs my new house... holy heck.  Old house 1986 single story 1227 sq ft single pane windows, new house 2005 2117 sq ft 2 story.  My average summer electric bill in the old house was over $300 some as high as $450 (this is for AC obviously) in this house I haven't had a bill over $100.  BTW they are only 20 minutes from each other.  Gas bill in summer is running me $9.  Winter bill got as high as $30 I think. I think winter electric was about $60.  Oh and we had gotten rid of the 2nd fridge at the old house... but have one here.   :)

I've gotten a bit too acclimated with the California temps... I was camping with the Scouts a couple weeks ago and I was freezing.  I made some comment about it being in the 50s and everyone was like its still 80.  I thought no way.  I went grabbed a sweatshirt to go with my shorts, came back they had pulled out their iPhone to prove to me it was indeed 80.  But compared to 100+ with the sun shining I was freezing, goosebumps and all.

I can't imagine having an electric bill in the hundreds of dollars. My 1,300 sq. ft. brick house was built in 1963 with single-pane windows (storm windows on one bedroom). The bats of insulation in the attic seem to have shrank over time and don't fit tightly between rafters. My averaged plans run $97/mo. for electricity and $66/mo. for gas. Electricity is most likely going to increase about 25% soon, however, after having cheap rates contractually frozen for years.
