Should I Get A Block Heater For My Toyota Prius?

With winter right around the corner, you may want to think about getting a block heater. Or should you? Here are a couple reasons to get a block heater and one reason to say no.

When winter rolls around and you live in a colder climate, you can bank on seeing a pretty significant drop in your fuel economy. Winter is a harsh on your Toyota Prius for more than that reason though. In this article we will look at reasons to get an engine block heater, the benefits of it, and why not to install one.

What Is An Engine Block Heater?
An engine block heater is a unit that fits into your engine block and keeps it warmer in freezing cold temps. It is designed to warm the engine antifreeze, oil and engine parts.

Why Is An Engine Block Heater Useful?
In very cold temperatures, keeping your engine fluids and components warm do several things. First, it helps reduce wear on your vehicle. Warm engine oil will flow faster and protect vital engine parts. Second, the engine will get up to operating temperature faster meaning you will see less of a drop in your Prius fuel economy.

Between keeping your engine in a constant "ready to go" warm state and helping improve you fuel economy, an engine block heater sounds like a complete win right? Well from those standpoints yes. However there are a few things you should know before installing one of these.

Why Not To Install An Engine Block Heater
If you are like me and live out in rural area, you may want to reconsider getting that block heater. The reason is only because of where I live. Out where I am in the vast rolling fields of grain and other things we grow in these fields are these pesky creatures called mice.

Now in the winter believe it or not mice love to go where it is warm. If your engine is warm where do you think those mice will want to go? Bingo. I have enough problems with these darned creatures already and giving them a nightly warm hideout is not something I am interested in doing.

An engine block heater is something that certainly help improve your fuel economy by about 10 percent or more depending on your climate. Other things to consider are the cost of plugging your vehicle in on your electric bill.

My take on this is that a block heater is worth it if you live in an extremely cold climate, away from rodents, and have a way to offset your added electrical costs.

They do, reduce wear on your engine and help to maintain fuel economy. If I were going to change where I live and want to maximize my fuel economy I certainly would do it.
