Best spot for a steam radiator in a small room

branimalbranimal Posts: 79Member
I'm renovating a building and I need to choose a spot for a radiator in small room. The most important thing is the radiator doesn't affect furniture place / usability of the room.

It has to go along the wall with the windows.

Options are:
1. under the window b/c people typically don't put furniture in front of the window.
2. In the weird angled corner
3. In the 90 degree corner.

Any thoughts?

    Mercy. That's not a room, that's a closet. From the standpoint of heating the room, it really won't matter -- radiators circulate warm air (naturally) pretty well. From the standpoint of using the room, though... although option 1 is conventional, I think it's problematic, as that is where someone will have to walk to get into the corner. On the whole, I think I'd go for option 2, and put some sort of clever set of shelves over it, starting about a foot above it....

    That room isn’t even 100 sqft, are you sure it legal?
  • branimalbranimal Posts: 79Member
    yeah its legal. 7 feet in a building with 3 or more bedrooms is legal. The other bedrooms are standard size.

    The only place left for someone to put a typical dresser is in front of the window so option 2 is really the only option, by the numbers.

    What’s the heat loss of the room? Could you go with option 2 and use a riser right in that corner as your source of radiation?
  • mikeg2015mikeg2015 Posts: 913Member
    Steam or hot water? If steam a small wall mount single section might work well. If hot water, they make some really small panel radiators. I agree, option 2 would be best. Maybe a shorter shingle tube or column radiator like those used for bathrooms.

    Thanks guys.

    Danny - good idea on the riser. The pipe coming up is 1". I'll google heat loss calc and get back.

    Mike - it's single pipe steam system.

    How do you plan on controlling the heat in that closet?
    Only 2 outside walls, well insulated there wont be much heat loss, any calculations on the total BTU's required?
  • KC_JonesKC_Jones Posts: 4,150Member
    You need to do the heat loss on all the rooms. I’ve read some of your other posts and this is like a new system with all the work being done. Room by room heat loss, size the radiation accordingly.

    Since we're all critiquing the room, I'd have the door swing against the wall, not into the room.

    There was a post here where the guy made his own radiator in the bathroom, very small.

    Maybe the microtube system

    Any chance for a small piece of cast iron baseboard, properly sized and pitched?
