We all have dreams. Some of them are nightmares, some of them aren’t. But then suddenly, out of nowhere, you wake up and I arrive like a bolt out of the blue to tell you about today’s plumberparts.co.uk video. We’re gonna look at S Plan systems today and the 2 port valve that’s absolutely integral in an S Plan system. So get ready for the wildest journey of your plumbing life. Let’s just go. So an S Plan heating system is just another way of controlling where hot water goes from the boiler. It can either go to the indirect hot water coil on the cylinder to heat hot water up that’s gonna come out the taps, or it can be diverted off to heating radiators or you can have another valve that diverts off to underfloor heating or even another zone for another radiator, all individually controlled by different thermostats and time clocks.
Today we’re gonna look at the very simplest type of S Plan that you can have. That is, we’ve got one valve here that goes off to the hot water cylinder and one valve here that goes off to the radiators. But before we start, as ever, don’t do any work on electrics if you’re not happy and competent and you don’t have an electrical tester. Always make sure everything’s turned off. Always, before you remove a wire or anything like that test and make sure it’s dead, okay? Because otherwise that how you’ll end up. Dead!
First, let’s have a little wee look at the electrics. So with this cover off, here. Now as you can see, sometimes you’ll go to places and the wiring’s just bonkers. You know, look at that, you might think, “God, where does everything go?” But if you isolate each one like we did on the 3 Port system that I showed you a few weeks ago in the videos, we’ll be able to find out where to remove each wire and where to put the new one in for the new valve. Get yourself a bit of paper and write down everything, every colour, and what block it goes to, and where it runs off to, okay? Now, there is a common principle with all control valves, that they need to be open and signal the boiler only once they’re open to tell the boiler and the pump to come on. If that wasn’t there, the boiler and pump could come on with the valves shut and have nowhere to dissipate their heat, could crack boiler sections and cause leaks and basically a whole hubbub of hell. Fortunately, all the manufacturers have thought of this, so when you do your wiring, you have your earth, your neutral, then you have a live feed to the motor itself so when the thermostat calls for heat and everything it will send a live to this and the motor will motor around, and then it has two wires left. Now, it’s a switch, basically, that’s all it is. There’ll always be a constant live to this. This is why when you need to test for electrics in these things you need to be careful and make sure the constant permanent live is dead, cause it’s a switched live. The only way you’ll ever do that is to wire set the whole system electronically by turning it off and removing the fuse. Now, you have the live supply, you have the permanent live comin’ in on one wire. When the valve opens up, it touches a smaller marker switch and sends a live back down this wire to the boiler and the pump to tell them to come on. It’s the same on all these valves, okay? Sometimes the wires on different valves are different colours, but generally nowadays they’ve tried to make them so they’re all the same so it’s easier for you to change. If it is different, have a little look at the book that was supplied with the valve and make sure the wires go in the right place, then. Let’s have a look at this S Plant system in situ. We’ll also describe that at the office in a second. We have our boiler flow coming from here. It goes up there, just across the top to the pump, which you can see just here, and then it comes down to this T here. Now it can either go off by this valve, off to the hot water cylinder to heat the hot water or by the faulty valve that we’re removing to the heating system. That’s basically how an S Plan system works. They’re generally controlled by a programmer and a series of thermostats. The good thing about an S Plan system is you can have as many different zones as you like. So you can have, as I said, underfloor, different radiator zones, different cylinder zones, things like that, which make it a lot easier to control the services in your home.
Let’s just have a quick look, schematically, about how these systems work. Imagine we have our boiler here, with our pump flowing water in that direction.

“ECHO” machine is a multi color 3D printer has been designed using of the addictive manufacturing techniques regarding the rapid prototyping process. This is technique known as (Fused Deposition Modeling – FDM). First, and like all 3D printer machines, the CAD file of the part which is wanted to be printed to a 3D object is exported with (STL) extension. This extension allows the 3D printer program to view the part as accumulative geometric surfaces rather like the surfaces resulted in (Finite Element Analysis – FEA). Using the 3D printer program, the part can be converted to many tiny slices and then these slices are sent in successive method to the 3D printer machine so the part will be built slice over slice until getting the full 3D built part at the process end, as a result this built part and the modeled part in the CAD program will be alike. This technique, for the purpose of building implement, is count on melting a thermal polymer which pours after positional melting form the actuator head nozzle. The actuator head traces the cross section of the processed slice and builds according to it until the full completely of the slice section. The procedure is repeated many times to complete the part building. This technique uses another thermal polymer as a supporting material to fill all part gaps and to support the built part body is case of balance adjusting during the building process. After the building end, the support material is got rid of and we will get a part or a product built from just the building material.
In this printer, the thermal polymer (Acrylonitrile butadiene styrene – ABS) is used, this plastic polymer melts in a Celsius degree between (180 – 220) degrees, and it’s provided in the markets as a filaments coiled around a roll, the used filament diameter is (1.75mm), ABS filaments substance has a color vary (in this machine the blue, red, yellow ones are used as a building material).
Regarding the supporting material, the used thermal polymer is (Polyvinyl acetate – PVA), this plastic polymer melts in a Celsius degree between (180 – 220) degrees, and it’s provided in the markets as a filaments coiled around a roll, the used filament diameter is (1.75mm) and it’s often found in white color (the roll located at the right side of the machine). The important specification for this material is the ability to dissolving into the water. Consequently, after building the part, it’s enough to submerge it into the water and so the supporting material will dissolve into the water and the building material will remain.
Both of building and supporting material are provided to the actuator head nozzle by means of a feeding mechanism which consists of a feeder for the purpose of pulling in the plastic filament from the roll and then guiding it into a canal ended with the melting chamber which is in touch with a ceramic heater (40 watt). And thus, the material is melted and poured out through the nozzle which has an orifice with diameter of (0.5mm). The feeding mechanism includes a cooler made from aluminium substance to prevent the heat from transferring toward the top. The number of actuator heads and feeders is four (three actuator heads for building and the remained one is for supporting). The heat exchange can be done for the four coolers by two fans behind the actuator heads.
Regarding the Mechanical Design Side, this machine has three axes (X,Y,Z). it depends for moving the actuator head along the (Y) axes, which it represents the machine gantry, on a motion method consists of a stepper motor and high accuracy synchronous pulleys and belt. The motion of the axis (Y) vertically along the axis (Z) is achieved by means of a pair of ball screws located at the two sides of the machine. According to the (X) axis, it’s the motion of the work table to front or back using stepper motor and synchronous pulleys and belt. In all axes, guiding mechanisms are used, they consist of rails with (V) shape and over them wheels with (V) shaped grooves are moving on them. In the (X) axis, in addition of the previous guiding mechanism there is a cylinder guider “Ball Spline” which is used to add more support for the table.
The work volume or field for this machine is (40cm×40cm×40cm).
Regarding the Dynamic Analysis, the inertia forces and torques were studied, and so the maximum and minimum velocity required to move the actuator head. Consequently, stepper motors were chosen, the number of them is like the number of the axes, these motors rotate (0.9 degree) by each pulse they get, these motors characterized with a high accuracy, the value of rotation will surely taken in consideration to determine the printer accuracy, the load torque for each motor is (4.4 Kg.cm). The building speed according to the (Y) axis is (150 mm/s) in maximum.
