Just before you install it don't forget to clean the inside of it.

Shipping/packaging problem
The radiator would have worked just fine if it had been packaged better. Two of the legs were broken off in transit. This size radiator should have been crated or put on a pallet. It was just shipped in a cardboard box with styrofoam boards around it.

Looks Great, the only thing is that I thought it would come with plugs for the un used holes.

Took back some wall space
Customer service was excellent. The product shipped promptly. A good source for this product. The radiators are exactly what I needed for my renovation on an 1805 brick house. It had baseboards that took up way too much wall space.

Cast Iron Radiators
We just bought another two radiators to fix our system, which makes six altogether this summer. So far, they seem to be working just fine. We haven’t tested them in very cold weather, and the house is in Michigan, and a rental. It’s surprising how well these are working so far, since they’re so much smaller than the Victorian ones previously in there. The old ones leaked and had to be replaced, unfortunately, since they were so pretty, but they were considerably bigger, and these new ones seem to be working as well, and don’t make such a large statement in the rooms. We got back some real estate replacing them. Shipping was timely, and the packaging adequate enough for them to arrive intact.

Looks Right
This cast iron radiator has dimensions and appearance that make it an ideal replacement for an century old one that would cost more than twice as much to restore. Can not comment on its function until heating demands are placed on it.

Check your dimensions before ordering
Smaller than I expected, but my fault for not really measuring and just assuming it would be like the 100yr old ones already in the house. Looks great though and will install this week.

The radiator is just what I needed. A local plumbing shop was able to sell me a valve and the necessary plugs. Everything went together fine. One small issue is that the actual delivery date was a week later than estimated when I purchased.

Pee-Yew!
The radiator came quickly and is exactly as described. The local heating/plumbing guys (Keeler Services) installed it with no problem, except for finding the right size plugs for the many unused openings. But the house stank for days afterwards from the smell given off. I guess there is some sort of anti-rust coating that causes it. I do sort of wish that they had larger ones. This is about 1/2 the size of the one it replaced.

Fit and finish
Radiator had a bit if sharpness on the parting line of each segment. Pretty sharp. I took a 4" grinder to it and in less than 5 minutes smoothed it out and had it prepped it for paint. Otherwise no issues. Very satisfied.

Very good pricing and shipping
Haven't installed this yet, but quality seems good - just a couple of small burrs sticking out that I filed down to avoid anyone scratching themself on it - and the price was very reasonable what with free shipping. I am still seeking advice on how best to remove one 1/8" plug to install a steam air vent; it's not apparent what tool to use.

A little wabbly
Radiator was just a little wobbly. Some felt under the legs took care of it. Other than that, its a solid radiator. I wish it would have been flushed with a rust inhibitor before it left the factory. Would have made my life easier.

Radiator came primed and threads were greased. Met my expectations for a foreign made product. I wish they would have flushed it with a rust inhibitor, but you can only ask so much for this price.

FAQs

Ask a Question
dose this radiator have openings at each end. or just top and bottom.
Helpful? Yes 2 No
Both sides have top and bottom connections for hot water or steam (2 x on ea. side = 4 connections total) - unused outlets would have to be plugged with black plug fittings. Also, only 1 side (pictured) has air valve/vent tappings, which are factory-plugged and can be removed with a hex key.
