Diesel Pressure Washers

Monday, October 12th, 2009
There is a straight cost issue when deciding whether to go for a petrol or diesel pressure washer. Diesel powered will last longer than a petrol driven pressure washer but petrol is cheaper.  A diesel engine will use 10% to 20% less fuel to achieve the same work, then there is little cost difference to pay back the increased price of the diesel pressure washer.   

However, if you buy your fuel from a fuel distributor and get agricultural diesel, it only costs about 25% of the cost of road fuel. When you use red diesel and you use your pressure washer for 50 litres worth, or four hours per day, five days per week, for 48 weeks of the year, then your savings will be approximately £1500, at February 03 fuel prices.

The amount saved is more than the difference of the purchase price in the first place. If you only use your pressure washer for one or two hours per week, the added cost of investing in diesel power, would not provide enough savings, to pay back the added cost of the investment.

Petrol Pressure Washers

Wednesday, October 7th, 2009

 

There are three main classes of petrol or diesel pressure washers:

1. Hobby – usually petrol driven, up to 5hp and use a vertical crankshaft engine, like a lawnmower, and have a small wobble plate pump hung underneath the engine. Like your lawnmower these are designed to be used occasionally for short periods of time. They won’t suck their own water either.

2. Budget priced – look the same as professional equipment but all the corners have been cut. You can identify this type of pressure washer, as it will have no reduction gearbox between the pump and engine. Reduction gearboxes are expensive but allow the pump to turn much slower. This means that the pump is not designed to suck its own water. It may do when new for a few months but it is primarily designed to be fed from a hosepipe. Check with your water supplier to see if this is permitted. (Most do not)

3. Industrial – what you need if you earn a living from pressure washing, or use pressure washers for long periods of time. Characterised by having a reduction gearbox which allows good suction and top of the range engines, designed to last, with quality filters and fittings.
