Would warm air rise through the Grill. OK the Grill needs a cool surface air inlet to replace this. Now what if these were dug under the floor of every ground floor room of a newly built house. Might work, any body tried it, do you get warm air rising from deep holes. Might not full fill all space heatimg needs but might allow the homeowner to turn the heating down a few notches, all because the housebuilder dug a few holes as he was building the house. That being said, why not have houses, half underground, so the botton of the house is permanently warmed. OR during construction, bury water pipes deep down, the water warms, rises into radiators which warm the room and return the now cooler water back underneath the house. There is no need for pumps, the warm water will rise naturally, the cool water will cool and 'fall' down the return pipes, setting up a natural flow.
