Modification ideas for boondocking

Well, if someone wanted to get REALLY fancy (if they weren't using a heat exchanger) they could add a thermostatically controlled EL Cid (as per smkittner noted in my thread about a recirc system) pump to heat the water and pump it when the temps got cold. But either way, hydronics would need to be insulated in the areas you DIDN'T want the heat to release towards.

Just about everywhere I go has lots of sun as I am on the dry side of the Sierras and there is a lot of open sky here.
