Has Anyone Installed a Circulation Tank Heater in an Insight?
 

I did a search but mostly found my own threads. LOL.

"Ooh! This guy is intelligent and insightful! Oh, right. Me again!"

Kind of like this?

I installed a circulating heater in my Civic (RIP). Ultimately not successful. Here's what happened.

I left a hose fitting poorly clamped. It did not hold under pressure and lost coolant. By the time I figured out what happened it was too late. Damage done.

Mine was a convection-based heater. Heated fluid should expand, causing it to rise in the hose, creating circulation. Very difficult to find a hose path routing that supports this.

Pumped circulation heaters are harder to find and more expensive. But that's what I'd look for if doing a circulating heater again.

I can strongly recommend a plug-type heater.

Most cars accept a heater in a frost plug fitting. Most Hondas instead, accept a heater in the block coolant drain plug threads. Substitutes for the plug. Civics and Accords have it on back side of engine, just to the right of the oil filter.

I had one installed by a shop and I'm pleased.
