How do Radiant Heating Systems work?

Central heating break down in the big freeze? Here’s why…
The recent cold snap has revealed a major problem with ‘condensing boilers’ – they don’t work in freezing weather.
How do I balance the radiators in a old pushed hot water system?

I live in an older house (80+ years old) with pushed hot water radiant heat. In the upstairs, two of the rooms and the bathroom are much hotter than the last two rooms. They all have adjustable valves on them, but my landlord said these will only shut off the entire system, not change the flow to each radiator. I think he’s full of crap. Does anyone have experience with radiant heat systems and know how the balancing process works or what I could do to get more hot water through the last two rooms. These two rooms are the last on the system too, but the water level has been checked and is full.

I will haunt you if you leave one word, useless answers. THANKS!

I’m having the same problem in my house – I have a maint contact with the heating company, and they’re coming next Wednesday – send me with your email address and I’ll try and explain how they do it for me – couldn’t figure it out on my own – I adjusted the little key steam valves at the top (kept them open while I heard hissing) and the round handle valves at the bottom, but I’m getting nothing in 2 of my 2nd floor rooms – they worked fine last spring
