Ecoxantia found some heating pads at RS. They look OK, the pricing is close to Wolverine's, but the dimensions appear to be much larger. This should keep the oil from burning, but may be hard to find a big enough spot. For example, their 100W heater is available in either 10x15cm or 20x15cm, while Wolverine's 125W pad is 4x15cm or 7.5cm diameter round. My oil pan won't fit anything bigger than 8x12cm, so I'll have to stick (pun indended) to the 7.5cm diam model.
RS does have a 50W pad for 220VAC (item nr 245-613), but it is also 10x15cm, while my transmission's smooth metal area is 3 times smaller
Can't stop thinking about it, though...
Here is a link to the 50W pad:
Selfadhesive heatermat, 50W 100x150mm
So, does anyone think we should try to negotiate with RS, or do we stick with Wolverine?
So far I've got word from vtec-e, Jabb, and Ecoxantia that they are interested, so that would be 4 pads including mine. I'm guessing that their discount will be similar to what
Titan offered 5 years ago (15%). I'll e-mail them today and ask for more details.
Anyone who is interested, please measure your oil pan and tell me which model you would like. I'm getting model 9.0-240 (125W, 7.5cm diam). If anyone would also like battery or filter heaters, go ahead and say so.
I'd like to order next week.
EDIT: They confirmed that the rebate is 15%.
