"...for an on demand propane tankless heater but my instructions say not to use pre-heated water."
thanks for the heads up, Mark. i will look into that further. right now i have a regular tank style heater, but was hoping to switch to the tankless on-demand type soon. curious what the specs for the tankless type heaters list as the recommended temperature range of incoming water.
