Hello All,


Firstly I am a DIYer, generally a fairly competent one… (he says!). I am looking for some advice on the placement of a pump (Salamander Force CT 30). The aim was to have the pump as a whole of house pump, but if not with my setup, just for my showers. I have attached a basic drawing of my system which I hope will help. My main issue is around the hot water supply from the cylinder. From the 22mm connection it flows to a usual T and then up to the expansion and down to supply the rest of the house. I will be putting a Surrey flange on the tank to draw the water without air. I would then, generally I think, put the pump on the flow from the outlet sideways from the flange, piped near to the base of the cylinder etc. However, here comes my problem/lack of knowledge… As my boiler is located on the first floor, the expansion pipe also appears to T off on the floor above and supply hot water to two of my showers. The other run from the T goes up into the loft and into the expansion tank.


So, based on the above I have two questions: 1. Is this set up correct and standard? 2. Where should I be placing my pump to ensure the showers both benefit?


Thanks in advance – I really appreciate your help, my brain just isn’t good enough!

From the cylinder to the tank

Thanks Shaun, I appreciate your help. I have attached a drawing/scribble of what I think you mean - green are new runs and pump placement.
Essentially, I would run a new vent from the top of the s-flange and then use previous vent/feed pipework to run everything else only - elbow off instead of a T where it used to go up to vent. Then put pump on the feed run coming from the horizontal run from the s flange. The drawing may explain this better!!

Thanks in advance.
