Hi Shawn2. A company called Apollo builds a system which fits your query,but they are quite expensive.There are other ways to achieve the same results for less. You can use a tank, an Aqua-Star or Seisco tankless unit, two pumps,a correctly sized radiator-type heat exchanger and a thermostat. This setup will heat your home and take care of all your other hot water needs. I can supply the heaters and diagrams to make it work. I can fax or E-mail them to you. Call me,800 851 9891 or e-mail the waterguysers C/O hotwater@structurex.net Happy heating.Brian Wood of Hot or Not Marketing Inc.
