PRESSURE WASHER: WHICH ONE TO CHOOSE?
Written on 14/09/24 by Cinzia C.
How many times, at the end of winter, looking at the terrace of the dirty house (moss, mold or autumn leaves) caused by seasonal weather or after having worked at home and even after painting, reducing the floors to a palette of colors, we face the dilemma: "... and now, how can I clean it?" Nothing could be easier if we had the right tool: the pressure washer!!!!
The pressure washer is a device that uses the cleaning power of water by increasing its pressure; the pressure of the water coming from the domestic tap is a bit more than 2 bar, while the pressure coming out of a pressure washer reaches very high levels ranging from 50 to 200 bar and more.
Water: an essential element for humanity
Man is by the presence of water; thanks to it, the human race has evolved; without it, it would not have the possibility of survival. The evolution of the human species has gone hand in hand with the presence or absence of water, and in the future perspective, it has become a primary good, increasingly valuable, almost sacred. Every small and significant achievement of man has originated from the exploitation of water and only thanks to it we are what we are.
Without wanting to give a completely misplaced philosophy lesson, it is fair to say that the industrial revolution took place thanks to the exploitation of water. The birth of commodities (mechanical equipment) and instrumentation technology have gone hand in hand with water exploitation; thanks to its use, a new world has opened for tools, appliances, and devices that are now part of our daily lives.
Water is the essential element on which the operation of the pressure washer is based and, therefore, on the exploitation of the pressure generated inside it. However, not all are the same, and it is good to know the characteristics to make the best purchase.
HOT OR COLD WATER PRESSURE WASHER?
One of the factors that underlie the excellent quality of the pressure washer is the water flow supplied in one hour. A minimum capacity to have an optimal effect is about 320 l / h. In addition to this, we must verify another significant factor, the pressure with which the water is "expelled": The natural pressure with which the tap water exits in the domestic network is around 2 bar; a good pressure washer can increase the water pressure from 50 to 200 bar or more. In this case, the cleaning power of the pressure washer is excellent, and the results obtained are undoubtedly optimal. If we want to increase these results, we can choose more powerful and higher performance items, such as hot water pressure water. These are high-performance machines, directed primarily at the industrial and professional level, but also find a great response in domestic cleaning. Practically they are capable of supplying water at high temperatures with high pressure, and they can easily clean and disinfect any impurities. The water is heated through the passage inside the same pressure washer, using a burner or by connecting it directly to the hot water of the domestic network (in this last case, there are only a few models that do not have great success in the market due to excessive consumption they generate).
KARCHER- HOT WATER PRESSURE WASHER
As mentioned above, hot water pressure washers are machines conceived and designed almost exclusively for a professional or very particular use. In addition to having the high-pressure jet, water can reach 90 °C of heat in a few moments and provide the power of cleaning and disinfectant not comparable to any detergent !! Persistent dirt, especially old deposits, mold, dirt, moss, clogged sewage pipes; the uses for a pressure washer with hot water are infinite and, in all cases, the final results are excellent! In most cases, pressure washers have an electric motor, petrol, or diesel, which drives a pump that gives more or less water pressure. A regulating valve allows you to regulate the amount of water that is going to be recycled in the head, varying the pressure/flow relationship of the outgoing water. The advice we want to give, however, is not to recycle the water, since the high temperature could wear down the internal parts of the pump, damaging it substantially.
HOT WATER PRESSURE WASHER- LAVOR
Lavor hot water high-pressure washers stand out for being excellent machines but at the same time compact, easy to handle and therefore also suitable for the less experienced in the field. This last factor is significant because everyone has different levels of experience, especially for beginners; this does not mean that you have to give up a high-pressure washer of a certain level.
With the Lavor brand, giving up is not an option, because its hot water high-pressure washers are very easy to use. Still, at the same time, they can provide high performance, adapting smoothly even to professional use and are the perfect combination of power and ease of use.
HOT WATER PRESSURE WASHER COMET
Comet hot-water high-pressure washers are a guarantee in terms of performance. It is no coincidence that Comet stands out as a leading company in the design and construction of pumps for agriculture and industry and it is well known that they represent the heart of the high-pressure washer.
Entirely manufactured in Italy, Comet hot water high-pressure washers meet every cleaning requirement in both domestic and professional environments, thanks to a jet so powerful that it literally breaks up the dirt. Still, the exciting aspect is that despite being equipped with motors capable of working at an intense rate, they are unrivalled in terms of guaranteed durability and reliability.
ANNOVI REVERBERI HOT WATER WASHER
Annovi Reverberi hot water high-pressure washers are the top choice for those who do not compromise on details and quality of materials, but at the same time are looking for a versatile and handy machine. Its hot water high-pressure washers have been designed both for professional contexts and for domestic use. Their common denominator is undoubtedly the ability to satisfy even the most particular needs, thanks to the maximum customization of each model. Annovi Reverberi never disappoints because of the accessories provided, thanks to which you can adapt your high-pressure washer to the most varied uses.
GUIDE TO PURCHASE: HOT WATER PRESSURE WATER
In recent years, the hot water pressure washer has implemented its market, introducing numerous models that have several fields of use, intended for amateurs and professionals.
To choose the best one we provide you with a brief purchase guide.
1. The first step is to evaluate the power of your hot water pressure washer.
The real power of the pressure washer is the sum of three factors:
- PRESSURE: It is measured in BAR and is the force with which the water leaves the machine. It affects the field of use of the pressure washer, as each surface withstands a certain amount of pressure. For example, if you use a machine that dispenses too much water on the car chassis, it could damage it. In general, the higher the pressure, the more efficient cleaning. Then consider the type of impurity and the surface you want to clean.
For amateurs users, we recommend a pressure washer with hot water that has a pressure that varies from a minimum of 20 to a maximum of 110 bars.
For semi-professional use, we recommend products with a pressure between 100 and 170 bars.
For professional industrial use, we recommend products that exceed 170 bars pressure.
- MAXIMUM RANGE: It is the amount of water that the machine delivers during a period of time. In general, we consider the liter/hour (l / h). This data, together with the pressure, will help you to understand which is the pressure washer that can satisfy your needs.
- POWER: Indicated in kW or watts. It varies according to the model and your demands. For an amateur pressure washer, the kW range from 1.3 kW to 1.8kW. For the semi-professional models, the kW change between 1.9 kW and 2.1 kW. Finally, the machines suitable for industrial uses are around 2 kW.
2. Now you must take into account where you will use your hot water pressure washer:
If you plan to use the pressure washer to clean small or medium-sized areas, such as:
- Garage
- Patios
- Sidewalks
- Exterior walls
We recommend amateur and semi-professional machines that can range from a minimum of 20 bar to a maximum of 110 bar. For semi-professional uses pressure water of 110 bar to 170 bar is preferred.
Others, on the other hand, are ideal for continuous cleaning and for demanding jobs such as:
- Tractor with embedded mud.
- Truck with burnt oil
- Barn
- Workshop
Speaking of water pressure, it is essential in these machines. Let's talk about a pressure that goes from 170 bar to more.
3. LineOnLine Tips:
- The accessories are essential for your hot water pressure washer. To make the most of it and exploit it in all its fields of use, we recommend buying a machine that comes equipped with quality accessories (or buying them separately).
(Outdoor work kit: Slider surface cleaner + tube washing probe + brush + detergent)
- We remind you that hot water pressure water can be either electric or petrol powered. Electric pressure washers still need diesel to heat the water.
