• Will A 125W Heat Pad Be Enough For 6 Quart Oil Pan On Pickup In The Winter?
  Roger, the Zerostart 3 inch pad # ZE75MR is rated for 3–6 quarts, so you’re right at its upper edge. It’ll still help, but if you’re in extreme cold below –10°F or want faster heat-up, adding a second pad would perform better. Either way, you'll be safe to use it overnight as it has a thermostat that shuts it off or turns it back on when needed. We also have a magnetic version # ZE35MR which puts out a little more heat and it just sticks onto the steel surface, then removes when you hit...

• What Is The Difference Between Zerostart Heat Magnet And Silicone Heat Pad?
  Good question, Luis. The Heat Magnet # ZE35MR runs hotter - up to about 250°F on its metal contact surface - while the Silicone Pad # ZE75MR cycles between 170°F and 200°F. The magnet’s higher heat is ideal for thick oil or frozen hardware, and the pad’s gentler, adhesive-based warmth suits long-term fluid warming on sealed pans. The main difference comes down to how the magnetic version is not permanent and needs to be removed before the machinery/vehicle drives off, while the silicone...

• Can Magnetic Heater Pad From Zerostart Be Used On Aluminum Surfaces On Equipment?
  Ken, for aluminum, go with the adhesive Zerostart pad # ZE75MR instead. It’ll bond directly and heat evenly across the surface. The # ZE35MR magnet heater only transfers heat effectively through ferrous metal, so aluminum won’t work - even if you clamp it, most of the heat will stay in the heater itself. What equipment are you heating?

• Will Stick On Heater Pad Work To Keep Big Hydraulic Pump And Reservoir Flowing Good In Unheated Shop
  Definitely, Walt. Cold oil thickens and bogs hydraulic systems and pumps down when you first start using them. If the tank or crankcase is steel, the Heat Magnet # ZE35MR works great and is easy to move when hitting the road. If it’s aluminum, use the Silicone Pad # ZE75MR - it’ll stick permanently and keep the oil warm enough for smooth startups. How big is your system? What exactly are you using it on?

• Can Magnetic Oil Pan Heater Stay On While Driving Diesel Truck In Winter?
  Glen, the Zerostart Heat Magnet # ZE35MR works great for cold starts, but it needs to be removed before you drive. It’s designed as a portable heater for parked equipment - vibration could knock it loose on the road. When parked, just stick it to a clean, flat steel oil pan, plug it in a few hours before startup, and it’ll keep your oil warm and ready. The built-in thermostat limits surface temps to about 250°F, so it’s safe to leave plugged in overnight. Do you usually plug in with...

• Can I Use the Same Magnetic Heater Pad For Tractor And Generator Motor Oil?
  You sure can, Doris - that’s one of the big perks of the Zerostart Heat Magnet # ZE35MR. It’s fully reusable/moveable: just unplug, lift it by the handle, and place it on the next metal surface and plug it back in. The built-in thermostat protects it even during extended use, so you can swap between machines as needed and just leave plugged in. Are both units steel-pan engines? That’ll confirm you’ll get full magnetic hold on each.

• Can ZeroStart Transmission And Oil Pan Heaters Stay Plugged In Overnight?
  Yep, you're fine, Mary. Both the Zerostart Heat Magnet # ZE35MR and the Silicone Pad # ZE75MR have thermostats that cycle off around their rated temps, so they can safely stay plugged in overnight. Many users keep them on all night to ensure an easy morning start. Just be sure cords are clear of hot or moving parts, and unplug them when you're ready to start and hit the road. What vehicle(s) do you plan to use these on?

• Can Zerstart Silicone Heater Pad Flexible Enough To Mount On Curved Transmission Pan?
  Alan, the Zerostart Silicone Pad Heater # ZE75MR has a small amount of flex for slightly curved or uneven metal surfaces, but it’s not meant to wrap around corners or big bends. The heating element needs full, even contact to transfer heat properly. Make sure the metal is clean and dry, warm it up a bit (around 100°F) before applying, and press it firmly in place for a solid bond. Are you planning to use it on a vehicle or on stationary equipment? That’ll help narrow down the best mounting...

• Magnetic Heat Pad To Stick On Polaris Ranger UTV Engine And Transmission To Heat Up Fluid And Oil
  Jake, absolutely - the Zerostart # ZE35MR magnetic heater is a great match for small UTV engines if the oil pan is steel. It delivers 200 watts of localized heat, which thins the oil and eases cranking even in sub-zero temps. Also helps warm the engine up much faster! If your pan’s aluminum, swap to the silicone pad # ZE75MR instead. How long are your cold starts taking right now? And does your battery ever go weak? That’ll tell us if pre-heating oil alone is enough or if a battery warmer...

• How To Pre-Heat Electric Steps On RV Motorhome In Alaskan Winter So It Doesn't Jam In Snow And Ice
  Hey Shelly! Interesting idea there. It's not technically designed for that specific situation, but I don't see any reason why you couldn't do that! The Zerostart Heat Magnet # ZE35MR works great for that kind of cold-weather fix. Just attach it to a flat steel part of the step frame or mounting bracket (anywhere on the bottom of the step away from the motor and wiring), and it’ll transfer steady 200-watt heat through the metal to melt ice and free up the moving parts. It’s a quick way...

• How To Keep Engine Oil Viscosity High During Winter On Big Generator - Oil Heat Pad
  Good question, Terry. If your generator’s oil pan or engine block is steel, the magnetic Zerostart # ZE35MR is easier - it sticks instantly and can be moved to other equipment. But if the part is aluminum, the magnet won’t grab, and the Zerostart pad # ZE75MR would be the right pick. It adheres permanently and provides steady, moisture-sealed heat. Both draw minimal power and make cold starts way easier. Do you run that generator on a timer or plug it in manually before storms?

• Stick On Magnetic External Heater For Stock Tank That Freezes In Winter
  It can, Carla - a lot of folks use the Zerostart Heat Magnet # ZE35MR for that purpose. Just attach it to the outside of the steel tank below the normal water line, and it’ll transfer heat through the metal to keep the water from freezing. The built-in thermostat holds temps around 250°F, so it keeps things thawed without overheating or damaging the tank. How big is your tank? I can help you decide if one magnet is enough or if you’ll want a second for larger setups.

• Can I Plug Zerostart Magnetic Heater Into Extension Cord For Tractor Outside?
  You can, Eddie - just use a grounded outdoor-rated cord heavy enough to handle the 200-watt draw about 1.7 amps. Keep it under 25 feet if possible or go with a 12-gauge cord for longer runs. The # ZE35MR magnet heater is great for tractors, and since it’s thermostatically protected, you can leave it plugged in overnight without worry. Do you have a metal pan on that tractor?
