Some Parts Washers are insulated and some aren’t. With today’s high electricity costs only insulated parts washers make sense.
Non insulated washers can cost up to and beyond $14 a day to run. Insulated Spray Washers cost only a fraction of that because with an insulated washer there is still heat in the tank the next morning if the lid is kept shut.
When purchasing a Parts Cleaner it is important to check that the lid as well as the body of the tank is insulated. An insulated Stainless Steel Hot Wash will save you a lot of $$$ in running costs over a year and being Stainless Steel they are built to last.
