I have a lpg combi boiler supplying 10 radiators. The central heating system is of a two pipe design.
All of the radiators are fitted with a thermostatic valve and a lockshield valve.
I am familiar with the method to balance radiators using thermometers with a supply and return system and adjusting the lockshield valve to achieve the difference in temperatures flowing in and out of the radiators.
I do not now how I should be setting the lockshield valves on my system where the flow out on the two pipe system goes back to the boiler and not on to the next radiator.
With the frightening cost of lpg I'm keen not to burn more gas than I need.
Thanks
