Hello,

Can you recommend a certain brand of electrical baseboard heaters that would replace existing units that were installed in the mid 1970's. Thanks, Chevtri

They all work the same. The liquid ones are no better for energy savings than to regular style. Do a Google search and you will find many manufactures. Take your pick they are all the same and let your wallet be your guide.

Personally, I would go Fan Forced heaters (Cadet stlye).

Yep but then you have to mount them in the wall and replace the fan motors when they go bad plus they make fan noise where the baseboard type are quiet.
