I believe this has been a topic before...how to best heat hot water if you are now using pellets as the main source for heating the house. Currently, I am heating the hot water with oil and burning 350 gallons a year which is 95% for hot water. Been researching alternatives and have been looking at heat pumps. I cam across this one (broken link removed to http://www.nyle.com/water-heating/) and was wondering if anyone out there is using it in Maine or New England or some place that is on the colder side? Just wondering if it is working for you or not? Realize this is a little outside the pellet realm, apologize.
