As part of my plan to install a full drayton wiser system this summer, i'm looking to change my current C plan system into a fully pumped S plan as it seems to be a requirement of the wiser system.
I just wanted to check that my ideas below are correct.
My boiler is a Worcester Danesmoor 15/19 Oil fired boiler and from the installation manual it shows the following two setups for a basic gravity plan and Y plan.My system is exactly the same as the top diagram, but with a two way valve on the flow of the cylinder (and a cylinder/room stat).
Looking at these two diagrams it seems to me that it should be as simple as removing the cylinder from its current un-pumped feed (28mm) and return and plumbing it into the current central heating circuit (22mm) after the pump, replacing the 3 port valve in the second diagram with 2x2 ports, one on the heating side and one on the water side. Is this the correct approach? Is the reduction in pipe size an issue?
I'm also planning to move the current HW valve near to the boiler as it is currently next to the cylider in the airing cupboard and I have a lot more room in the cupboard where the boiler is situated.
Also, the boiler manual says there is no requirement for a system bypass, but is it still recommended to install one?
Is there anything else i should be aware of in doing this?
Thanks in advance for any pointers
