I have refused to shut down my Tarm for the season. I have no storage.... so when it is warm out... I just let it go out and get cold.... but when we have nights like last night... I fire it up.. 33 last night.... and then it can heat all the hot water for 5 showers in the am too. I guess i will wait until June before I do the official... clean out and inspection. It has idled a bit too much for my liking at times... but what is a man to do when he is addicted to his Tarm? For the experts out there... tell me how idling can be detrimental to the Tarm? Are there any lasting effects to the Tarm is it idles too much?
