boat hot start to heat sparge and strike water

[sar_dog_1]

So I had a boat hot start (block heater) brand new and tried to see how fast it would heat 5 gallons of water to175 deg. Obviously I would not be using a jabsco or the attached hoses. With 80 deg water to start, it took 1hour to heat to 175. I am going to remove the element and try placing it directly into the pail and time that. I will post my results.. btw it is a 120v 1500 watt element.

What metal is that made out of? It does not look like it would be safe for food contact!

Aluminum

Ok so simly immersing the coil took 1 hour as well. I am hoping to cut the time down while heating the water in the cooler itself. The bucket was really hot and I think I lost a lot of heat. I am gonna try it tomos.

But sinse the time was the same, I am gonna stick with the immersion type. I simply pulled the element out of the heater and flipped it around and reattached. This gives a tested watertight seal with no issues. Just gotta figue out how to safly mount to the inside of the cooler so it does not touch the walls.

I would love to hear any thoughts on this as I am only still setting up my first all grain brew stand. Thanks in advance!!
