Is it a Heatbank or a Thermal Store(sludge bucket)?

Primatic cylinder is fed from CWSC so not sure about the "semi" bit...

HaHa it is a real system mate honest. apparently ours was fitted in 1998 it,s a primatic cylinder with a bubble and its classed as a semi gravity the boiler is a kingfisher MF 100 with a gravity flow and return and a pumped return i when,t on the boiler man site and found out what it was.

A Primatic cylinder is a single feed indirect cylinder, sometimes fed from a header tank.

If you google semi gravity it must be an old way of doing things

How many you fitted Dickie????
Only indirect until the bubble bursts..
The heating system is filled via the same cistern which supply's the hot and cold down services..
Whatever you do don't pull the boiler stat phial in order to clear an airlock..

Been a while since I had the pleasure of a primatic system. Never heard it called a semi anything.

You gotta love it when diyers make schit up to sound like they have a clue. Had one on the phone the other day trying to talk his way to a phone diagnosis to save a few bob. Was painful listening to all the made up terminology. Almost as bad as watching Scotty on star trek.

Are you saying i am making this up Dan !! the semi gravity system was used from the 1960,s to the 90,s the boiler heats up the hot water cylinder by natural convection it has one hallway stat no MV,s if you check out the honeywell site you will see the original layout i,m not talking schit obviously you,ve never seen one.

You're talking about a C plan. And yes. I am VERY well versed in domestic control strategy.

 

[Dan Robinson]

A primatic system is a primatic system. A c plan is a c plan..

 

[Dan Robinson]

Although, strictly speaking, a cplan had a start and valve on the primaries too.

Fitted loads back in the day Steely. Even with Solid Fuel Room Heaters. They're total cr.p!!

Six radiator, Primatic cylinder & Stelrad Elan. All done in a day & done streets & streets of them.
Great money but hard graft.

Yup commonly done around here. Also fully pumped with 1 zone valve for the CH.
