Flexible Oil Reservoir Heating Pads, Filter Heaters and Battery Warmers

Start Your Engine In The Coldest Temperatures

Frequently Asked Questions.


Q: What does a Heater Pad look like?
Heater Pads are thin Flexible heating pads built to conform the outside surface of an engine oil sump or any metal fluid reservoir.

Q: How are Heater Pads installed?
Heater Pads are easily installed by following the step by step instructions and with basic shop tools. Everything needed for a complete installation is included with each heater. No special tools or skills are required.

Q: How long has Heater Pads been on the market?
Heater Pads both Engine Oil and Hydraulic Heaters were released to market in the Spring of 1988 following 3 years of developmental work and testing.

Q: What is the warranty for a Heater Pad?
Heater Pads have a 3 year warranty.

Q: Why is it important to Heat the oil supply?
A: A Heated oil supply results in:
1) Less drag for quicker startup
2) Immediate oil flow to reduce wear
3) Greatly reduced water and acid contamination of oil

Q: How hot does the oil get?
Heater Pads raise oil temperatures to approximate operating levels.

Q: Is a thermostat required?
A: NO, When the heater is sized correctly, a thermostat is not required.

Q: Will a Heater Pad burn the oil like immersion type heaters?
A: NO.
Heater Pads apply Heat to the oil through a very large surface area. 
Because the temperature of that surface is far below the level that would 
damage oil, the result is a gentle and even Heating.

Q: How long does it take a Heater Pad to do it's Heating job?
Heater Pads will generally raise cold oil temperatures by 40°C in 1.5 - 2 hours. 
Full Heating is usually accomplished in 5-6 hours.

Q: How does a Heater Pad do a better job of Heating the engine than block heaters or tank type heaters?
Heater Pads put Heat into the oil supply. HEAT RISES to warm important INTERNAL components.

Q: Are the pistons included in the list of Heater INTERNAL components and if so what temperatures are they warmed to?
A: YES. Pistons are generally warmed to 30°C or so as governed by variables in engine type and design.

Q: Will a Heater Pad raise an engines coolant temperature?
A: YES. Remember HEAT RISES off the heated oil supply.

The crankcase walls along with the cylinder wall, the outer block wall and 
the coolant between them create a very effective barrier to the loss of heat to the atmosphere. Only a small amount of Heat is absorbed by the coolant resulting in a 10-15° increase in coolant temperature.

Q: Can a Heater Pad be installed on a curved surface?
A: YES, a
Heater Pad can be installed on single plane curves as short as about 1" radius. 
They are not to be installed on a compound curve area.

Q: Can a Heater Pad be moved from one engine to another?
A: NO. The installation of
Heater Pad is of a permanent nature.

Q: Can a Heater Pad be installed on the side of a pan?
Heater Pads can be installed of the side of a sump or reservoir, below the oil level and will yield excellent results.

Q: Can Heater Pads be used on diesel fuel tanks?
A: We recommend against an installation on a diesel fuel tank due to the possibility of overheating the fuel supply.

Q: Can Heater Pads be used on transmissions?
Heater Pads are suitable for all types transmissions.

Q: How do Heater Pads compare in use of electricity with old style coolant heaters?
Heater Pads , application for application, use less energy than block or tank type coolant heaters. Heater Pads are more economical to operate than block heaters. Compare watt ratings.

Q: Will a Heater Pad save me money?
Heater Pads will save you money by increasing engine and starter life. They are maintenance free and use much less electricity than a block heater.

Q: Can the use of any coolant heater presently in place be discontinued?
A: YES, the use of any block or tank type coolant heaters can be discontinued.

Q: How do Heater Pads stand up in an environment of grease, oil, dirt and periodic engine cleanings?
Heater Pads are constructed of materials resistant to the effects of oil, grease, dirt and water. Direct blasts with the pressure washers used in engine cleaning should be avoided.

Q: Are there other available in other voltages?
A: Yes. There are heaters available in 220 volts ac, 120 volts ac and 12 volts D.C.

Q: What electrical connections are on the Heater Pads.
A: The 240 volt Heater Pads are supplied with a 1.8m cord without and electrical plug. The 120 volt Heater Pads are supplied with a 1.8m cord and a 3 pin N.A plug. The 12 volt dc Heater Pads are supplied with18" lead wires.
