thanks for that, I was told to buy the grease when a new bearing is installed ? any other comments please ?

Hi, Currently replacing the bearings on an ARISTON CDE12X. Just wanted to clarify where the oil seal grease should be applied. I assume it is on the inside bit of the oil seal ? Drawn a piccy to help its in my album, its not accurate I know, but just need to understand where the grease...

OK servotech, I have had a look at the diagrams, and am a bit confused. I would prefer option A, as I think I can fit the pump near the boiler on the HW return from cylinder and link it up. But you seem to be suggesting from your arrows that the flow of water is the other way around the...

Current Setup Proposed fully pumped Setup

Also added some diagrams myself of what the current system looks like and what I think you are suggesting, plesae can you have a look and let me know if that is what you have suggested. Just confirm where on the HW flow I can put the pump plz, its easier to put near boiler as I have some room.

yes most of the piping is horizontal. I have had a look at the diagram, just a few points of clarification. First, can I add the pump on the flow near to the boiler instead (does it matter where the pump is fitted as long as it is on the HW flow ? Second, not sure how the air separator...

Servotech 9/10m is quite a long run for 22mm gravity circulation pipes you may be better off fitting a a pump after all - you could always fit one afterwards if it is too slow and wire it independantly of the boiler controls with a off/on switch and cylinder stat to control it. A little...

thanks mysteryman, would I be able to upgrade to fully pumped with what I am proposing in the future ? If so that's fine, the problem I have regarding the fully pumped bit is that I have to do lots of work moving the pump (as its on the CH return, installing 2 port valves (somewhere without...

thanks servo, that's really helpful. So 22mm vent with a tee from HW flow (just before the connection to cylinder), and a 15mm feed on the return. Just making sure the joins can be made nearly anywhere along both those pipes (HW Flow/HW Return) ? Otherwise I will have to rip up the carpet...

yes, staying gravity fed at the moment, as its easier to sort (I think) so will replace the primatic with an indirect 1200x450 (or something like that). I presume I can always convert to fully pumped afterwards using the above ?

OK, not much luck with the first post. Can anyone assist on the first bit which is if I replace the cylinder I will need to add a header tank,so can I join the header tanks feeder pipe (to fill the system) onto the HW return to the boiler using a tee just after the cylinder connection...

Hi, I have a primatic cylinder and would now like to replace this sometime during the spring/summer for a number of reasons. The key ones being, it doesn't produce enough hot water (growing family, tank is small), I can't use any inhibitors in my heating system and I am trying to get more...

yes, sorry i didn't make it clear what i was asking, the power on a 2 port would open close the valve, I was trying to understand on a check valve it works in a similar fasion, so its closed normally due to gravity effect and is open by the pressure of the pump pumping water through it ?
