I have heard from many customers that they think because the chemicals are so much better than they were 20 years ago it is OK to clean with cold water.
Cleaning carpet with cold water is like cleaning clothes in cold water. It still works but hot is a lot better. In fact, if you remember from your tenth grade chemistry class the speed in which water molecules vibrate is double at 136 degrees F. than water molecules at 118 degree F. Every 18 degrees of water temperature increase exponentionaly doubles past 118 degrees. For example, 154 degree molecules vibrates 4 times faster than 118 degrees. The opposite is true. When water cools below 32 degree, vibration slows down the water molecules that the liquid become a solid and forms ice.
With all that said the theory is that with hotter water, you can use a lot less chemical, dwell time, and agitation to achieve the same results. The is what is called the cleaning pie. The cleaning pie consist of four equal slices. Heat, Agitation, Dwell Time, and Chemical Action. If you increase the size of one of the pie pieces the need for each of the other remaining 3 pieces is reduced. It does not matter which pie piece you enlarge, the theory remains true. The best possible cleaning would be a system that says all four slices in abundance. Why do you think people spend $10000 on a truckmount (more heat, pressure, and vacuum and more automation) or on a Volcano 6000 watt heater if they use portables?
I also want to comment on the heat that you will get out of a 2000 watt heater. All the brands of the 1750 watt to 9000 watt heaters use thermostats that turn the water heater off when the water temperature reaches 210 degrees. (like when you set the wand down and quit cleaning or a while) The rate of water temperature rise is based on power consumption and water flow. The average in-line water heater only holds 8 ounces of water. Some heaters hold a little more water. The Mytee Turbo and Volcano 6000 hold 32 oz of water. So when you are cleaning carpet, the water is flowing pretty fast through the heater and the average temperature rinse is only 25 to 50 degrees F. When cleaning upholstery, because the spray jet is small and uses less water per hour, a 2000 watt heater is quite impressive. The breakdown is for standard dual jet cleaning expect a 10 to 15 degree rise for every 1000 watts of energy you place in the water. For power wands, these results are cut in half and with hand/ upholstery tools, these figures are doubled. Please note that cleaning and water pressure and jet size also play a part in temp rise. If I have a machine with a 100 psi pump and cleans at 65 psi with the trigger squeezed will get the water much hotter than a 500 psi machine that cleans at 375 psi with the trigger squeezed. Please note the jet sizes primary used on our industry. 11001, 110015, 11002, and 11003. The first figure is the spray angle. The aforementioned jets all would clean with a 110 degree angle. The last numbers represent the size of the orifice. 11001 is twice as small as a 11002.
Sometimes people tell me "25 degree is not very much improvement, is it really worth the money?" My answer is "Yes!" Twenty five degrees is past the 18 degree temperature rise mentioned above, so you will more than double your cleaning efficiency!
