How do you regulate a radiator in one room?
In the case of a cast iron radiator, you would vary the flow of steam or hot water to it by throttling the valve that feeds it. In the case of a "convector", you would vary the quantity of air that passes over the coil by adjusting the air shutter. lc
What is a column radiator used for?
A column radiator is used to describe a typical cast iron radiator. The term describes the vertical columns that make up the radiator. The radiators can also be made out of steal and not cast iron. The steal is welded together.
What are two companies that produce at least one cast iron model of radiator?
There are several companies who produce or sell cast iron models of radiators. For example, try the company 'Cast Rads' of the 'Radiator Center' for these radiators.
Is comfort ironing water demineralized and suitable for car coolant mixing?
No, comfort ironing water is not suitable for car coolant mixing as it is not formulated for automotive use. It is recommended to use distilled water or coolant specifically designed for cars to ensure the proper functioning of the cooling system.
If you have cast iron radiators that heat your home what is wrong with some of the upstairs radiators if they get half hot and some don't get hot at all?
Answer There might be air trapped in the radiator, try bleeding. It's usually a flow problem. If the valves on all of the radiators are wide open, the steam will flow through the path of least resistance, often leaving some of the radiators lacking for heat. Try turning down the flow on some of the hotter radiators. You will need to spend a little time adjusting the flow... assuming that you have flow adjusting valves on the radiators. These old cast iron radiators have sections that are bolted together. Each section has a gasket to keep the steam or hot water INSIDE the radiator. Of course these old radiators collect rust over the years unless you are very careful and scientific about your water chemistry (most folks are not). You probably have a plugged hole in one of the gaskets between the section of the radiator that is getting hot and the section that is not getting hot. This "cold" section is being bypassed and not receiving any flow.
How do you clean new cast iron?
Normally if there are no roots water Jetting restores full flow by scouring the lines to like new condition
Pipe size for a cast iron radiator?
1/2" - 2" depending on demand
Why do iron ship flow on water?
because it is designed in such a way for the ship to float on water
What is the direction of flow in a cast iron hub and spigot drain pipe?
from the hub to the spigot
How can a cast iron radiator be shortened?
Buy a shorter one. Welding Cast Iron is a pain and to do what you want would require cutting out a section and re-welding the whole thing. Baseboard hydraunic heaters can be shortened but cast is a no go.
Why don't the upstairs cast iron radiator heaters work?
Most often because they become air/water-locked. A cast iron radiator system works by sending steam (which naturally rises) up from the lower level into each radiator. When the steam heats the cast iron it loses enough heat so that it cools back to a water (liquid) state. When this happens, the water must flow back to the burner all by itself, propelled ONLY BY GRAVITY. So if at any point in the loop ANY length of pipe has sagged so that it is not downhill enough to allow the water to drain, the system will become locked at that point and no steam will pass by, thus cutting off heat to all radiators beyond the blockage. The most common fix for this is putting shims underneath the feet of the radiator on the opposite side of the pipe only, thus angling the radiator down for full drainage. Many times people will cause the issue themselves by putting a floor or tile underneath the radiator, inadvertently removing the angle. Other times, the natural sagging of the house removes the angle put in when the system was originally installed. So, your best bet is to 1.) Shim all non-working radiators downward toward the pipe, 2.) Drain the whole system (from the spigot at the base of the burner) of all water (and air), and 3.) re-fill the burner with water to the appropriate water pressure. Replacing the steam valves on each non-working radiator is a good idea as well.
Cleaning cast iron?
To clean cast iron use hot water and a cloth or sponge. Dry the cast iron right away. You should not use soap, and you should never soak cast iron or it will rust.
