Single radiator in a large room question

[elmocambo]

Is it practical or possible to heat a 5M X 5M 2.4M height room with one 10,000BTU radiator ?
The room is properly insulated with douple glazing.
I know multiple radiators are normal in this situation, but my circumstances will only allow the possibility of only one
I am led to believe.

Sounds possible.
Need to know wood floors or solid?
Type of room?
Outside walls?
Build/wall type e.g. 11" cavity walls or fully insulated etc. To give Btu requirement but if you've done that correctly to get to the 10,000 Btu, fine.

Have you checked the Delta T of the rad @ 10,000Btu'? It normally says on literature for the rads.

There is no problem using one rad that is sized correctly. You don't need to have multiple rads.

Have a look at a k3 rad will need 15mm pipework if you have 10mm it’s a no go

The room, a former garage will comply with current uk building regulations U value guidelines when converted.
The k3 rads look like what I need, but I couldn't find the Delta T information on the Stelrad website.

What’s your flow temperature?

 

[elmocambo]

The flow temperature appears to be 52°C according to my DMM sensor

 

[ShaunCorbs]

So 60 probably

So conversion factor 0.492

So 1000w at dt29 will require 2033w at rad spec of dt50

Look at this chart.
It tells you flow and return temps at the top and delta T (DT).

DT in this case is temperature difference between radiator surface temperature and room temperature.
You can see the rad outputs and sizes on the page you choose.

Pipe size matters as ShaunCorbs mentioned.

Hope this helps.

What is a DMM sensor?

I thought it might be digital multi meter

Maybe you're right.
