The system is made up of heavily insulated feed-rods that lead to floor-rods which heat the rooms; much less bother than hydronic heating which requires three inches of poured concrete around it as thermal mass(?) and as a clumsy workaround for having relatively flimsy non-structural plastic tubing on/in
the floor.
Heat source can be any mechanism; furnace, induction, heat-transfer from a hot-water tank. While it would take longer to heat up than a comparable system, computerized control should be able to keep up with normal dynamic heating needs.
It can't break down, requires no maintenance, is totally recycleable and could even be an active structural component in the house design.

Took a few reads to discount the concrete red herring, and I now get the solid rodness over pumped water thing. The pumping of high specific heat capacity liquid and computer controlled valves is probably easier than mechanical separation circuits. |
|
| |
The only circuit control is at the heat source to allow individual metering of heatflow to the feed-rods, unless that's not what you mean in which case... what ? |
|
| |
Depending on where you want the heat, you're going to have to break the rods dynamically in each room, typically on the ground floor where heat is likely to be in excess. Or are you just talking about a bar heater system in each room ? |
|
| |
Concrete ? Thermal mass and overnight electricity tariffs don't even enter into the inefficiencies of this system. |
|

"heavily insulated feed rods conduct heat to the floor rods which heat the rooms" - that what you mean ? The feed-rods would be vertical and under-ceiling runs which aren't affected by any need to be structural so you could pile on whatever insulation you wanted to. |
|
| |
No, I get it. I just wondered how 'metering' turns into control without physical breakage of the rod (assuming they are all connected to the same heat source and is not just the equivalent of a bar heater in each room). |
|
| |
depending on the heat-source you might have a short run of something between it and each rod. (I like the idea of pulling the rods out like in a nuclear plant, but since that wouldn't work, I'm not gonna go with it). For instance, using a combined water heater, all the rods would lead in and on the inside of the tank each rod could have it's own adjustable "condom" to limit contact area. |
|
| |
And the reason I'm going for feed-rods instead of having a separate heater in each room is safety and total lack of maintenance-bother. |

Hmm, lots of solid copper bars rather than one water circuit. But I will use the variable sheathing idea for a probabilistic genetic purification program I have planned. Well, thats this idea that has me put to bed. |

Aluminium (copper's expensive) and you forgot my commission bun !!! |
|
| |
ok, [+] for your solid rod, but if anybody asks, nothing happened. ok ? |
|

[edit: this was much funnier when the idea was titled "solid rod heating system"] |

There's no smoke without a cigar. |

Actually, this would work with one main heating rod if you used fans to extract the heat or have an insulated cupboard in each room containing a radiator which could be opened as required. |
|
| |
You go running metal rods through a concrete floor and heating them up and cooling them down the thermal expansion will crack the concrete. They'll also need room to lengthen and shorten on a regular basis. |
|
| |
Wouldn't it be simpler to simply use thick copper wires and rely on resistance to supply the heat? That's already baked, BTW. |

issues with solid rod system:
1- Rate of heat transfer: proposed system is by conduction, not convection, thus very slow. Humans will be in discomfort for a long while. Heat capacity of iron is low; heat capacity of liquid water is much higher; latent heat of steam even much higher than that of hot water. |
|
| |
2- Heat loss inefficiency: If the room is overheated and with no heat pumps (not mentioned in the proposal) to pump the room ambient thermal energy back to the rod system, one needs to open windows. |
|
| |
3- temperature gradient: the rod temperature decreases as the distance from the heat source increases. Talk about heavy insulation. So a single rod heating both the 1st and 2nd floor is impractical. One needs a multitude of rods, each one dedicated to a given habitation space, where a single hot-water pipe will do. |
|
| |
4- Same issues if rod system to be used for cooling. It is easy to crank up the heat, not so easy to set the cryostat as low a temperature as needed, along with the problem of water condensate. |
|
| |
didn't consider expansion, though I've thought that the room-rods would become more flattened to increase the surface area. |
|
| |
Concerning the pink giraffes and the like, don't you people read ? |

I would think the outer edge of the room would be quite hot while the far end would be pretty darn cold. |
