Hot Tub. Do the jets need to be running for the hot tub water to heat?

Depending on the model most spas/hot-tubs will not heat without the water circulating.  The exception would be if the tub is equipped with a seperate circulation pump to move water through the heater.  Most spas have two-speed pumps- low speed to heat & filter and high speed for stronger jet action. Hot-spings does have a seperate circ pump to heat tub

Use a fan, (not plugged in), and put it in running water.

Any bacteria or viruses die and hot temperatures and mot hot tubs are kept at 104 degrees.  I think that is pretty hot.

I don't know, but mine do the same. \ngood idea why don't you or I invent the heated\nmouse? I could use the bucks.

Put it _under_ the hot tub! :P

Any heating system works on a simple system:\n\n1. A heat source ('boiler') heats a circulating fluid;\n2. The fluid is pumped around the system heating other 'areas'\n3. The slightly cooler fluid is circulated back to the 'boiler' where it is reheated - by doing this we do not have to introduce additional fluid and it is more efficient to reheat already 'heated' fluid.\n\nHope this helps but if you need more drop me a note.

The heater part will work fine, the problem will be with the pump motor. If the motor is actually 220 volt it will run ok but 12.5% slower (less water pressure) A lot of things in the US that are called 220 volt will only be using 220 for the high power part. I.E. a 220 window air conditioner often has a 110 volt fan, it only uses one hot leg and neutral. If your hot tub has anything (pump motor, lights, air compressor) that uses 110 volts, that part won't work without being modified. There is no neutral in European 220. In some cases you will get something to work anyway but it is using earth leakage on other wiring and will not last for long, the voltage isn't steady. It will also get you killed in a worst case. You will not have any trouble getting/finding a good electrician there to make the changes needed and it won't cost nearly what it would here.

No. In both, you have a blower, much of the power (volts x amps x power factor) for that is pushing air around, some of that power is lost in heat.\n\nIn a heater (furnace) most of the power goes to heating elements. The remainder goes to the blower motor.\n\nIn an air conditioner, you have the same blower that you have in the heater, you also have the compressor (using power). Like the blower, much of the compressor power is doing work (squashing a gas back to a fluid [once it move through the condenser]). The remainder is lost in heat. The condenser unit (outside of your house) has boat loads of heat radiating from it. This is partially the heat being removed from your house (the main function of the air conditioner).

Of course not..... the hot water isn't the only reason the mirror is steamed over....

Well, yes, all of these answers are pretty much correct.  They don't run on water, they run on the hydrogen in the water and then they reintegrate the hydrogen and oxygen to produce water as a by product.  Here is a neat little company (That I own stock in) that is working on this:\nhttp://www.ballard.com/\nBallard Power Systems (BLDP) for you home gammers.  \nAlso an interesting site for "water" based power systems for energy production is here:\nhttp://www.fce.com/\nThey are also working on fuel cell (water) batteries for lap tops.  Some of the laptops are actually going to a methane battery instead of hydrogen however.  \n\nPretty kewl huh?

It would be hard to determine this in the shower but does he perspire?  If his body is unable to perspire properly in unusually hot situations and there is adequate fluids in his body, this might be a cause to consider for the overheating.

its not like that , but according to HVAC data , the temp. underground is constant about 10 degrees celsius , so in summer its hot , then we find the water cooler , and in winter , the air temp. may be zero , so the water is hotter

If it has to be a WATER bath then you are limited by the freezing and boiling points of water, and the lowest you can get will also depend on whether the equipment is capable of cooling as well as heating - if not, then agree with previous answer, ambient room temperature is as low as you will get. If you have an OIL bath capable of both cooling and heating then your useable temperature range will be hugely expanded.

Don't burn your rubble unless you have running water. Sorry ehm.

Its because of the Jet Stream.

No running in Jacuzzi area..\nNo peeing in Jacuzzi\nNo farting in Jacuzzi\nGrandma and Grandpa not allowed in jacuzzi!\nNo pulling drain plug when people are enjoying jacuzzi\nMake sure to add chlorine once a week\nShould be fine

No,instead of cooling the room get heated up.\nthe compressor will have to do much work and heat will be given out.
