How do y plan systems work?
How do y plan systems work?
The Water flows from the boiler through the bottom of the valve, then the valve either sends the flow of water through Port A (to Heating), Port B (to Hot Water) or through both ports in order to heat the radiators and hot water together. Y-Plan heating systems were widely used in older heating systems.
What is Y plan heating system?
What is a Y Plan Heating System? The water comes through the bottom of the valve. This valve then sends this flow of water to either Port A, which is the heating port, or Port B, the hot water port, or through both, to work both the central heating and hot water simultaneously.
What’s the difference between s plan and Y plan?
The main difference between an S and a Y plan is that a Y Plan has a single, three-port valve supplying both the central heating and/or hot water. This three-port valve is shaped like the letter ‘Y’ when you look at it from a schematic layout of pipework point of view, as seen below.
Which is better s plan or Y plan?
An S Plan Heating system is also better suited to larger properties with higher hot water demands, as it provides superior flow rates over a Y plan. Other benefits of having an S Plan Heating System are below: Close temperature control on the hot water system and heating system.
Do you need a bypass on Y plan?
nope, leave it alone… The valve may remain at either HW or CH postion after time cycle…
How does Y plan work?
Does a system boiler need a bypass valve?
A bypass circuit must be installed if the Boiler manufacturer requires one, or specifies that a minimum flow rate has to be maintained whilst the Boiler is firing.
Where should a bypass valve be installed?
The bypass valve should be installed between the flow and return with flow in the direction of the arrow (see Fig 1). If a higher capacity is required for large installations it is possible to install two or more valves in parallel. The valve can be manually adjusted from 0.05 Bar to 0.5 Bar.
