Pressure Washers, Tires, Wheels, and More

Thanks for the question. Unless the pressure washer's pump has been equipped with special seals and packing to withstand hot water, you will drastically reduce the seal life in your pump leading to loss of pressure and the pump needing to be rebuilt. Depending on the manufacturer of the pump and style of pump, warm water (up to 100° F) can be used. If warm water is used it is then very important not to leave the machine in by-pass (the machine running without the trigger engaged/pulled) for longer than 1-2 minutes maximum as the warm water circulating in the by-pass line will gain temperature due to friction of water movement through the head of the pump and fittings causing the warm water to increase in temperature and damaging the seals. Hotsy hot water pressure washer pressurizes water then runs the water through the heating coils. Over the years I have seen many people who needed hot water in their cleaning try and use a hot water heater such as you have in your home. Not only does it effect the pump seal life a 30 gallon hot water heater will only supply a 3 gallon per minute pressure washer with about 7-10 minutes of hot water before needing 30-45 minutes of reclaim time making this very costly and energy inefficient. With a hot water pressure washer in 60-90 seconds you have up to 200 -210°s of hot water and a continuous supply with no reclaim time saving you time, utilities, maintenance expense and money.

When it comes to applying detergents there are several key elements you have to address. The first is water hardness - for every 5 to 6 grains of water hardness it cuts your detergents effectiveness by 20%. The soil application (or what your cleaning) is important as well, so the detergent is applied at the proper pH to clean the surface, while using the least amount of detergent possible. 10.0-10.5 pH for light duty stains, 10.5 – 11.0 pH for medium and 11.0 – 11.5 and up for heavy soils/stains. And the most important is the quality of the detergent. Hotsy has manufactured detergents for over 30 years and makes them specifically for extreme hot water usage. Once these are addressed a chemical orifice can be put in the detergent line and the same consistent water to detergent ratio can be applied saving detergent expense with better wash results. Applying too much detergent can actually leave a white chalky shadow or film on the surface. Your local Hotsy dealer can test your water conditions, soils, stain and application and attach a flow meter to properly set the detergent ratio to get the very best results.

Thanks for the question. If in clearing the coil you are referring to de-scaling the coil to remove any mineral build up, the process requires an acid based de-scaling solution, acid rated/resistant auxiliary pump, and acid rated/resistant plastic pail. Plumbing from the pressure pump is removed and acid solution line is plumbed then pumped into the inlet of the coil, travels through the coil and is circulated back into the pail. Depending on the severity of the scaling recalculating the solution can take 30-60 minutes. On coils with severe scale it may be necessary to dispose of the first quantity of de-scaling solution and circulate new solution. Do not run this solution through your existing pressure pump as it will ruin the pressure seals in the pump and can be harsh on other components. I suggest you contact your local Hotsy dealer to perform this service as they are properly equipped and have the expertise to insure maximum results.
