Type 22 normally has two water panels and two convector fins. Check the product specification for its exact construction and output.
Higher Output Panel Heating for Busy Rooms
A room with high heat loss may need more output than a shallow panel can supply. Double convector radiators use two panels with convector fins, increasing heating surface without simply making the unit longer. MacBlair stocks Firefly Type 22 panels in several dimensions within its plumbing and heating range.
Check the watt or BTU figure against a room heat-loss calculation at the actual system temperatures. Width and height alone do not reveal the full story: two radiators with similar dimensions can have different outputs. Also check projection from the wall, pipe centres, window positions and space for airflow.
Replacement work can involve moving valves or changing short pipe runs. Compatible copper tube and fittings and compression connections help plan that work. After installation, flush and treat the system according to the boiler and chemical instructions, using the correct water-treatment products.
Double Convector Radiator FAQ's
They usually produce more heat for a similar wall width, but are deeper. The better choice is the one whose output meets the room’s heat loss.
Projection varies by model and brackets. Check the manufacturer’s depth and wall-to-front dimensions, including valves.
Possibly, but pipe centres and connection positions must match or be adapted. Have the system and heat output checked before buying.
Often. Lower flow temperatures reduce panel output, so an installer should recalculate heat loss and radiator capacity for the proposed system.
