Epps manufactures a series of pressure washers, steam cleaners and combination units that heat water electrically. At 440 V 3 phase power they draw from 50-110 amps. Are they any good for your applications??? I don't know, but I have been asked to share what is up from a manufacturer's point.
Before you ask, they work on 3 phase only, 440 and 575 at 60 hZ and 380 at 50 hZ. They do NOT cost much more to heat water than a natural gas fired unit and depending on your area will cost less than propane, kerosene or diesel fuel.
Let me illustrate: NG cost $0.07452/cu.ft - a 345,500 btu burner uses 34.2 cu.ft./hour or a cost of $2.58/hour to heat the water. Electricity costs $0.04672/kWh- a 72 kW unit will cost $3.36/hour to heat the water. Kerosene cost is $2.50/US gallon, with a 2.25 nozzle for a cost of $5.63/hour.
Most applications are in-plant semi-permanent (there is an optional wheel kit). Depending on the size of the heater elements you can get from 80-150 degree F heat rise or up to 305 degree F steam.
No fumes, no additional fuel, no open flame, no excess heat etcetera. There are possibilities for use in many applications where the power is available. BUT these units are not for every application either.
We have just received approval for listing an explosion-proof unit for use in hazardous locations, UL-1203 Class 1, Division 1, Group C&D, Cl. 2, Div. 1, Grp. F&G.
These are highly specialized units but are mentioned here by way of illustration of what some manufacturers are doing to meet ever stricter environmental impact legislations. Be prepared, California will soon have strict emmission limits for oil fired pressure washers. You may not think so but look what they have done to lawnmowers, string trimmers, blowers and now snowmobiles. Small, light weight, 4-stroke, fuel efficient, clean burn motors all.
Just another product to let you know what is out there. Cheers, Michael
