ECN Forum Forums General Topics of the Trade General Discussion Area Hydronic electric baseboard heaters

Does anyone here have the Cadet SoftHeat hydronic electric baseboard heaters at home or have any customers that own them?
These are the type that consist of a finned copper tube filled with an 80/20-water/glycol mix and use an immersed heating element. I’ve only seen these in a couple of homes, but the owners generally seemed very pleased with them.
Other than the obvious safety advantage of lower operating temperature, are these worth the added expense over standard electric baseboard heaters?

Thanks
