I just moved into a modest 1917 colonial here in Michigan (after living in the north-east all my life) and I came across a heating setup I have never seen in a residential application before.
I have a standard gas fired hot water boiler and a two-zone circulating system with a combination of standard baseboard units in some rooms and in the main spaces (bedrooms, dining room, kitchen) what looks like standard upright radiators. However, behind the cover of each "radiator" is a coil & fan combination. When the thermostat calls for heat, not only does the boiler come on, but also does the fan in each of these units. Basically, the system is a hybrid of circulated water with mini-forced air heating.
Has anyone seen this before (in a residential application)? Is there anything I should know about these units (problems, issues, benefits)? And most importantly, should I start replacing them with standard hot water radiators? I only ask the last question because these units generate quite a bit of noise (especially when the fans are turned on high).
