Has anyone installed a circulation heater? Something like one of these;

seems like it may be a good alternative. They are dirt cheap compared to an Espar and as long as you have electricity they should work. Any thoughts on plumbing?

 

bump......

 

Zerostart looks like a good idea.... I didnt see a price and I am having a hard time with parts of the website as it is in the wrong language...

 

I haven't used one of those before. But I did install the one that goes in the lower radiator hose in my gas silverado last year. It worked fine even at the -30 to 50 we had.

 

IMHO, Espar is the only way to go for pickups. I've heard through multiple contacts that they have the least amount of problems.

 

I would like an Espar but for 1/10th the price and myself being near electricity 99% of the time this may be the answer. I'm going to look into it when I get home from this shift.

 

I will be able to let all know a little more on the zerostart units, we just got a big IH loader and it has one installed, looks like a waterpump for a pond or such and I guess it has heating elements inside it as well. if it hcan warm the beast of a motor in the loader I am gonna look for one for my truck, block heater my but.... still cold air blowin when I pull into work in the morning, and home and night.
