There are two types of power washers- the first one sprays cold water, while the second type sprays hot water. Generally, most machines that are made for residential use are the cold water type. A cold water washer can successfully remove general dirt and grime. This type of machine is also smaller and lighter in weight than its counterpart. So, it is naturally easier to move around, haul, and store away. It is also less expensive to purchase. And, it comes in a wider variety of models than a cold water power washer does. If you have general duty jobs to do around your house, then a cold water power washer will probably work fine for you. Are you surrounded with dirt and tough stains that you cannot get rid of? Do you need a good pressure washing system that cleans evenly and effectively? Every application requires a certain amount of pressure to break the bond between “dirt” and the surface it is adhered to. Using pressures greater than 20% over the minimum required to break the bond will not improve the cleaning speed of the equipment. Fortunately, we know how to deal with that nuisance. Hot water pressure washers are best at jobs where significant amounts of oil or grease are present or if some heat reactive substance is being cleaned. Typically, hot water units perform better than the cold water ones. The main reason is that they have a capability of heating up the water of up to 200º F. In power washing process the heat is the most essential element of cleaning.

A hot water power washer has its disadvantages. It's heavier than a cold water machine. This is because it has a heating system built into it. This heating system turns cold water into hot water for better cleaning. A hot water machine is also more expensive to purchase. However, if you are looking for a power washer that will work efficiently on removing more difficult grime, the hot water machine is the way to go! Hence it depends on your requirement to select in hot and cold water power washers. We can only guide you at Power-Washing.org with advantages and disadvantages of both types of Power washers.
