What to Consider When Choosing the Best Hot Water Pressure Washer

Pump Quality

Best Hot Water Pressure Washer - Reviews & Guide

 The pump quality is one of the most important aspects you need to look into when getting a hot water pressure washer.  It is advised that users should go for devices in which the pump is made from high materials which can increase the durability and longevity of the unit. Getting a unit with triplex pumps is the best choice anyone can make. This is because they are equipped with triple plungers, unlike normal pumps that come with only one Plunger. They do last long.

Heating Capacity

When selecting a hot water pressure washer, one of the considerations one should have is how well the water is heated. Some device models heat water with diesel, gas, or kerosene.  A hot water pressure washer must be equipped with a burner that can reach high temperatures quickly so that users don’t have to wait too long to start using it. 

Ease of Use

Research more about the product and reading reviews online from verified purchase users to find out if the product is actually easy to use.  A hot water pressure washer must have an easy to maneuver feature which means that the tires of each product must be well-made.  A hot water pressure washer also requires an ergonomic design so that it would increase ease of use while also making sure users don’t get tired while using the product.

Technical Specification

One of the specifications which fall in the technical aspect is the PSI or pounds per square inch. This refers to the amount of pressure that can be produced as the equipment. On the other hand, the GPM or gallons per minute refers to the rate at which water flows out of the units. These two technical specifications will indicate the device’s performance as well as power.

Versatility

Versatility is an important factor when it comes to the hot water pressure washer and as a user, you need to have complete control over how the device is being used. Users have to be able to adjust their devices to get their desired specifications. Customers should look for models that have adjustable pressure and interchangeable nozzles so that they can select the type of settings they need for a specified task.

Types of Hot Water Pressure Washers

Best Hot Water Pressure Washer - Reviews & Guide

Hot water pressure washers come in two various kinds. These two types of products can be found on the market.

Gas-powered Hot Water Pressure Washer

The gas-powered hot water pressure washer is usually more portable. The engines of this type of hot water pressure washer help you keep the pressure washing level you desire or require to use.  Gas-powered hot water pressure washers need more regular maintenance and service unlike any other type of pressure washer.  Users need to constantly check the air filter of the device and they also need to check the oil level of the product so they can run their drive for a longer period of time. This type of washer is designed specifically to be used outdoors or in well-ventilated areas. The machine produces a lot of carbon monoxide and it is very harmful to the human body.

Electric-powered Hot Water Pressure Washer

The electric type is usually a silent but efficient engine that offers users pressured hot water for cleaning when compared to the gas-powered hot water pressure washers, you can tell that it is more convenient, easy, and very thoughtful to purchase.  This type of pressure washer also has a longer lifespan as they require only little maintenance.  However, Pressure washers always function at full capacity and they need constant electricity to keep them running. With that said, avoid using an extension cord so that the current would not be reduced in any way which can result in engine failure.

SIMPSON MB1518 1500 PSI at 1.8 GPM Diesel Fired Hot Water Pressure Washer review

4. SIMPSON Cleaning MB1518 Hot Water Pressure Washer

  • Fuel Type: Diesel
  • PSI: 1500
  • Water Volume (GPM): 1.8
  • Weight, Pounds: 205
  • Start: Electric
  • Hose, ft: 50
Check Price on Amazon

Key Features and My Experience

With only about 1500 PSI, the SIMPSON MB1518 Diesel Fired Hot Water Pressure Washer is the hot water pressure washer with the lowest compared to most of the products on this list. Because of this, this device is designed only for small-scale applications and use. The product also comes with a triplex pump and a 120-Volt induction motor which gives users results beyond their expectations.

To make it more versatile, the company added 4-quick to connect nozzles which users can interchange to tweak the pressure of the device.

There are 40, 25, and 15-degree nozzles as well as nozzles which are required for soapy occasions. The hose measures about 25 feet in length which is enough to move around during application. This means you are not near your device at most times.

Portability is not a problem either because this device comes with two bald tires that can be used to carry the device around.

Important Elements which Hot Water Pressure Washer Function On

Best Hot Water Pressure Washer - Reviews & Guide

When operating a hot water pressure washer, there are mainly three elements that are important enough to determine how hot water pressure washers effectively remove dirt and grease. The elements include:

Agitation

The first element is agitation which users also knew as the impact. This element exists as a result of the water capacity released through the device and also water pressure which usually hits the surface of your stained engine.

Heat

Heat is an important element when it comes to working with a hot water pressure washer. It tends to create a high-rapid action on the molecular level making this cleaning product more effective. This element also tweaks the water’s surface stiffness so that users can spear dust even at a molecular level.

Detergent

The last element which hot water pressure washers function on is the detergent which chemically destroys the connection between the grease and the surface of the stain. The detergents start working immediately as soon as the particles of the grease or oil stains get attached to the dirt along with the surface on which the stain is to be removed. This element also acts as an agent that softens oil making it possible to mix with water. The minute these two unmixable mix, the washer becomes easier.

FAQ

What is a hot water pressure washer used for?
When it comes to removing oil stains all that cold water can do is just to move the oil stains around. On the other hand, hot water removes those stains. Hot water pressure washers are devices used mostly when cleaning automobile parts, engines, or any machinery part with oil or grease. Hot water pressure washers work on things like removing anything from engines to discarding paint from the wall.
When to use a hot water pressure washer?

If there are stains, oil, or grease, you would require water pressure to remove any form of again quickly.
How does a hot water pressure washer work?
These devices work by using water heated to about 200 degrees F as well as a pump that delivers the heated water through a constricted nozzle. Depending on the company that produces a hot water pressure washer, you can get one that can start and stop automatically.
How to use a hot water pressure washer?
First, start out by making sure that your hot water pressure device is on a flat surface and also try as much as possible to check the pump oil level. Professionals recommend you use a 30 weight non-detergent oil. Next, add diesel fuel or kerosene to the burner supply tank. Next, connect a garden hose to the pressure washer and also to the other end which supplies the water. Set your pressure from about 20 – 40 PSI. When that is done, connect the male side of the pressure hose into the coil outlet found on the pressure washer. Make sure the trigger is in the” LOCK” position. Pick out the best nozzle which can handle the pressure of the machine. Install the nozzle. Then plug your device into a safe outlet and ensure that the GFCI is set. Put on the water and move the trigger-locked position to on. Test out the trigger by squeezing it to let out excess air from the system. Now turn the pump switch to ”on” and make sure your burner is in an ”on” position. Adjust the thermostat of your device to a temperature of about 200 degrees F. Squeeze the trigger to use.
How to winterize a hot water pressure washer?
To winterize a hot water pressure washer, run an antifreeze solution through the device. Unplug the water supply from your hot water pressure washer and connect the antifreeze container.

Try as much as possible to remove all the excess water and dry it. Flush out the detergent and water by placing the washers injection tube into a bucket of clean water.
Add the pump saver to the pump inlet.

Why does my hot water pressure washer smoke?
When a hot water pressure washer smokes, this process indicates that the engine of the system is not burning well. When fuel is not burnt well, it can accumulate soot in the coil. Soot accumulation on the heat exchange coil is a sign of an ill-maintained burner. Adding a soot remover to your engine may help prevent this build-up.
