Electricaire Units; The last 2 digits of the serial number indicate the year of manufacture. All units made after 1974 are asbestos free. Electricaire Units are sometimes referred to as Comfortaire heaters but NOT to be confused with the Comfortair heater (spelling). Comfortair was formerly the Redring Sunstore heater.
377 "E" type (distinguished by being a grey coloured unit)
"S" Type heater (distinguished by being a chimney breast shape)
"SF 6" Type (chimney breast)
"SB Type" (chimney breast)
Important Notes:
The above storage / storage fan heaters and E Type Heaters contained medium density semi-rigid insulation slabs of "Caposil HTI", situated more normally as base insulation of the core box containing the storage bricks. This material contained 10/15% brown asbestos (Ammosite), the balance being harmless calcium silicate.
Some of the heaters also contained a piece of Asbestolux (asbestos cement board). This contained 16/25% brown asbestos and a small un-quantified amount of white asbestos (Chrysolite).
The "S", "SF6", and "SB" Electricaire heaters contain a small sheet of "Viceroy" (Asbestos paper and aluminium foil corrugations 1" thick) in the warm air unit where the fans would be situated), either side of the fan unit.
