Sparge water heater

[dcbrookes]

I set the combi-boiler hot water to 65 and fill a couple of pots. No issues so far.

Don't think that would work too well. Combies generally need a decent flow to turn the boiler on and then flow for a bit until it starts heating the water.
I was thinking of putting an instant water heater on the cold feed to the shed but it's a bit pricey for the sake of filling a pot 2 or 3 times in the kitchen sink.
Diary spray and electric instant heat would be ideal for a small flow.

You would not have much control over sparge pH with that arrangement. Sparge pH is the most critical factor in avoiding tannin extraction.

Excuse the ignorance as I haven't started to explore PH yet but would it not just be a case of adjustment the same as you're mash water?

Yes, but that would not be possible if the water was sprayed straight from a water heater. It would not be a problem if it was transferred via buckets or such like.

Ah okay. Sorry, I was thinking how I currently do it. Haven't had my coffee yet

Interesting! I’ve just replaced my old vented hot water cylinder that need a water tank in the loft with an unvented hot water cylinder. As the new tank runs directly off the cold water main I was wondering about using my tap hot water for ALL my brewing water (both mash and sparge) to save on gas (propane).

I was thinking about that myself but I like to leave the mash water sitting in my Brewzilla overnight to remove the chlorine. Doesn't help with sparge water but helps for the bulk of the rest.
