Availability of Zerostart 3500025 frost plug block heater

[tcruwithme]

Zerostart block heaters are made by Phillips & Temro out of Eden Prairie, Minnesota (western suburb of Minneapolis). I recently put a 3500025 on my Deuce, but it was very hard to find. An internet search didn't bring up anything. The 3500025 is listed as for the Hercules/White engines, is a 1,000 watt, 120 volt, 2" frost plug block heater. I got a PM from another SS member asking where I got my Zerostart 3500025, so I contacted the manufacturer to see if they are still made.

Ian Vriese at Phillips & Temro told me by e-mail at 8:03 a.m. CST on December 10, 2014 that they still make these heaters, that they have them in stock, and that they can be ordered at any of the following retailers:

All State
I-State
Rihm
Boyer
O’Reilly
Bumper to Bumper

I got mine at O'Reilly for $70, but it was the last one they had in the entire company. This is good news that Phillips & Temro have these in stock, so they can be ordered. I hope this news helps other SS members in your search for a good block heater. Here are a couple of pictures of the 3500025:



Here is a PDF file of the installation instructions that came with the heater:

I would like to purchase the same thing for my m35a2. Does it go in the front frost plug hole or the rear hole?

I put mine in the rear frost lug hole (closest to the firewall) on the passenger side of the engine.

Wouldn't one of these be easier to install? I can't bring myself to punch a freeze plug to install something that may leak. Just my 2 cents.

Can’t wait to install mine!

That looks like a good unit also, especially since removing freeze plugs isn’t for everyone. Thanks for sharing!

Thinking of replacing this old recirculating heater with the Zerostart listed above. Does anyone have details on the old one in m pic?

Mine was delivered today. Hopefully some evening here soon I can get it in!
