According to the Domestic Building Compliance Guide (2010 with 2011 amendments) page 22 it states:
"Dwellings with a total usable floor area up to 150m2 should be divided into at least two space heating zones with independant temperture control, one of which is assigned to the living area."
How are you guys installing these systems? For a combi do you need a one or two channel programmer (it says temp control not time control?). I take it you need two flows from the boiler (will a three port valve do or do you need 2 x 2 port vavles?) and do you need 2 returns (to stop reverse cirulation?) Do you fit check valves to stop reverse cirulation too? Does this cause problems draining down? What about the extra cost to the customer?
As an apprentice, I worked for a big company and we never fitted systems like this but now I'm working for myself I want to make sure I'm doing everything correctly.
Cheers
