Q1). RAD above height of CH Boiler & Expansion Tank? IDEAL ELAN 2 RS30: Vented/Semi Gravity CH System?
or feasibly this would prevent the CH system from working properly, as it lacks the force to supply water in an upwards direction even with an EXTERNAL PUMP after the CH BOILERS FLOW output.
BOILER: IDEAL ELAN 2 RS30
EXTERNAL PUMP: RavenHeat Rs25 40/60/88w
CONDITION: CH System is in good working order, Room Temp Max 22ºC & RADs total within BTU MAX
BOILER: 1st floor in BEDROOM
EXPANSION TANK: 2nd floor in LOFT
Hence want to put new RAD on 2nd floor the LOFT above BOILER & EXPANSION TANK.
But there is NOT adequate room to move the CH BOILER into the 2nd floor in LOFT, however the EXPANSION TANK could be repositioned HIGHER UP then existing to be ABOVE future/potential/hypothetical RAD in LOFT.
I'm guessing from existing manual diagrams that accurately depict the current existing CH system install, it could be described as a VENTED/SEMI GRAVITY, it is CENTRAL HEATING only with no provision for DHW. Some of my family are plumbers however since they're young their education/training is of simpler pressurized Combi's, and old now redundant/obsolete systems before their time is guess work instead of actual factual knowledge. Also I spoke to Ideal and 'A PLUMBER' I spoke to say it relies on Gravity hence RADS are below the BOILER ONLY and obviously the EXPANSION TANK is above the CH BOILER to provide it with a greater abundance of water then just the COLD FEED.
After reading the IDEAL BOILERS MANUFACTURERS manual of this old MODEL made in 1984 thoroughly
I can't find any reference to positioning of Reds just below BOILER, however at the time it may have been implied as the common system of the time & Plumbers instinctively that then, but it might not matter just not mentioned then because loft conversions weren't popular.
So far each Plumber I spoken to so far has had a different opinion or recommendation, and I presume a lot of this has to do with their familiarity or lack of it, and their preference to suggest chucking the old system & fitting a Combi as compromises of less external bits!
Contradictory Suggestions so far:
I) RADS must be below CH BOILER & EXPANSION TANK
ii) RADS must be below EXPANSION TANK
iii) RADS can be above CH BOILER
iv) Chuck the old Boiler lot & fit Combi that would heat RAD above boiler regardless because it's pressurized
