HERMS Update

Last year, I did a series of posts on Heat Exchange Recirculating Mash Systems (HERMS) and the fact that I'm building one. Here is a quick update on that:

For my birthday, last December, I got a major piece of equipment I was missing, a March Pump. This will drive my system. I have been unable, as of yet, to use it because I need some hoses that are big enough to connect to it, and that can handle the heat. I think I found the ones I want at William's Brewing.

Once I get my hoses, I will take the whole system for a test run, with rice hulls and water in the mash tun. The idea is to test the rising and falling of temperature in the mash tun as I run hot water through the coils and inlet temperature probe, without actually brewing beer. This way, I can debug the system.

That is about it for my HERMS update. I'll keep you posted when I get everything I need to run the test.
