does anyone know offhand how to lower the pH of the circulating water in outdoor wood stoves?

Answer 1

Is this drinking/cooking water? or just water circulated for heat?

I dont own a stove like this, and the few Ive run across haven't mentioned it as a problem... but you might try pool chemicals. (I dont own a pool either, lol). I wouldnt do this if you planned on drinking or cooking with it, but just for heating purposes it might work.

I will suggest that you contact a wood stove dealership in your area... if you've got a problem with the water, then others in your area may too, and they may already have a solution for you. A second place to look would be a pool supply company.

I've read articles in a rural co-op electric magazine that there is a little gadget you can attach to the water supply line which is supposed to remove some of the heavier elements, and lower ph safely, but Ive had no experience with it. Here is the link - http://www.sophtecwatercond.com/

Answer 2

not clear whether you want make water more acidic to combat limescale (ie lower pH) or more alkaline to reduce attack / oxidation of metal pipework - but normally there are a range of proprietrary additives for most heating systems
