primatic

I can't get a consensus on this from four plumbers that have visited. We've been using the system with no prpblems for 7 years - but the cylinder leaks and needs replacing. It's an old and peculiar set up I have onherited after buting my two storey house. I would greatly appreciate any...

Hello everyone Before I succumb to this problem I’m reaching out for some help. There’s very little info on the web and I can’t get hold of a manual. The system is ancient but we’re not ready to renovate to a greener option for another 12 months so hoping to keep it going. Moved in with the...

Hi all, i have a primatic cylinder that needs replacing, are we allowed to install new primatic cylinders in this day and age or do i have to install a new vented indirect cylinder. Only asking as i found this quote on a website. If you have one of these tanks, you should seriously consider...

TLDR; Why are modern primatic cylinders unsuitable for use with an uncontrolled heat source? The scenario: I have a friend (really) that needs a new HW cylinder fitting. Currently there is a 40ish year old 36x18 primatic type cylinder in place (I assume that’s what it is as it is ‘self...

I have a nasty oil fired rayburn connected to an old primatic cylinder. I would like to drain the system and remove the rayburn. The radiator circuit has already been removed and blanked off from the heating circuit. Is there any reason why I should not drain the cylinder/heating circuit at the...

My parents have a Baxi Back Boiler with a pumped central heating system and gravity hot water system with a Primatic cylinder.

Hi All, So I found out the central heating system in my house has a Primatic cylinder so I can’t add inhibitor due to the risk of the water and hot water mixing. I am just fitting some TRV’s and wanted to replace 3 old rads with some new ones whilst the system is drained down. Eventually a...

Can't find some threads on here I saw a while ago so I'll start a new one. Customer had a Primatic combination cylinder (I thought they were only done as regular cylinders) and he wanted a direct replacement. There was some confusion as to whether it can be done or not. You can't get...

Hi all, Our house was built in the early 70's and we have a Ideal Mexico 2 boiler. I can't see any 3 way valve on the system and I was wondering how I can tell if the cylinder has a coil in it? The reason this has come about is because I tried to drain the CH heating system previously ...

Can someone explain to me how a primatic cylinder works?

If one was to add some radiators to a primatic system so that the air bubble was too small to accomadate expansion, is there any way to take up that expansion and retain a primatic system? would an open vent work? Asking purely out of curiosity as i bought that RD Treolar book someone on here...

done a job today changing a rad on a primatic system, wouldn't have taken it if i'd noticed before pricing it! so drained down (after 1.5 hours!) changed rads and filled back up slooowly. The pump is a high point (no vents) in the airing cup wedged between the cylinder and wall making it...

Hello All I'm a competent DIYer, fitted bathroom/kitchen but never really dealt with the central heating system. I want to replace a old single cast iron radiator for a new double convector radiator to increase the warmth in the room. So i started to do a little research on my setup. I have...

Hi, i have a primatic cylinder system which i will be replacing soon, in the mean time is it possible to disconnect the f & r from/to the boiler and leave the cold water supply to the cylinder from the header so it can be used to supply DHW only by using the electrical immersion? This will be a...

My father has an oil fired AGA cooker that heats his hot water, there is no central heating in his house. It connects to a primatic hot water cylinder fed from a single header tank. The cylinder has a cold feed from the header tank, a feed to 3 hot taps from the top of the tank and a feed in...

Hi. I think the answer should be straightforward but can't find it on here by searching, so here goes. I have a Primatic system, which works as it should. I changed and moved radiators on the system 15 yrs ago with no problems, and now I want to make some more changes. Being a competent DIY'er...

My 19 year old son, who is NVQ level 2 plumbing with 3 years experience, called me tonight. Had a customers heating system not working, could not work out why there was no F & E cistern. Asked if it was a sealed heating system, he said "no". I said "oh it's probably a Primatic". he said "a...
