I am thinking about using a series of boilers to heat water for the system. (It is not an hydronic system.) I need to use LP Gas as the fuel. I am checking the help command in eQuest and the only options I have is either "gas" or electricity. I assume that "gas" stands for natural gas. How can I simulate the LP Gas to use for the boilers? Has anybody done something similar? Any comments will be highly appreciated!<br></div><div id="yui_3_16_0_ym18_1_1459042152306_16869" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1459042152306_16738" dir="ltr">Kind regards,</div><div id="yui_3_16_0_ym18_1_1459042152306_16870" dir="ltr"><br></div><div id="yui_3_16_0_ym18_1_1459042152306_17007" dir="ltr">Jose Luis Bermudez Alcocer, Ph.D., M.Arch., B.Arch.<br></div></div></body></html>
