6 - A one pipe system cannot be used with convector radiators.
What do you mean by "convector" radiator?
6 - A one pipe system cannot be used with convector radiators.
4. Calculating rad sizes is exactly the same
Complete tosh.
2. Program the boiler to come on 10 mins sooner, they're a lot of advantage in a slower heat up, especially as it reduces boiler cycling.
Complete tosh also.

err yes it can
Yeah when you put your cowboy boots on.
Why don't you guys just admit it's an inefficient design well past its sell by date.
Theres also the issue of the extra cost of oversizing the radiators.
How do you define: convector? (as opposed to: "normal" rad)Convectors MUST have a pumped flow through them to acheive the rated output.

That what I was taught anyway.
The only one pipe loops I install are UFH.

A radiator that give out 800btu's doesn't give out less because it's a one pipe system, true not as quickly as a two pipe system, but not a problem either.
Those would indeed not do a lot on a one pipe system. I was puzzled by your statement as "normal" rads are often indicated as convector radiators.
figures state capability. even cold a rad's still capable of reaching spec (think about it) besides that you are misunderstanding 'doitall',what he is talking about is initial warm up.it still reaches target. just takes longer to get there-INITIALLY!A radiator that give out 800btu's doesn't give out less because it's a one pipe system, true not as quickly as a two pipe system, but not a problem either.
not to get in your way of your arguments but i would imagine the figures they give for rads would be btu/h, other wise any rad of any size could give out any figure of btu's given long enough...
we where discussing rads
One pipe systems usually have higher return temperatures than two pipe systems. With a one pipe system, it can be difficult to reduce return temperatures and it is very important to adjust the flow in the circuit correctly and to reduce the flow temperature as much
as possible.
