I will be renovating my attic to include 2 rooms and a small bath. I have opted for electric baseboard heat in these new areas.
I noticed an ad for silicone oil filled, variable wattage BB heaters in the magazine section of the Sunday paper.
They use a proportional t-stat as opposed to on-off control. I like the idea of proportional control and am thinking of either buying their t-stat for standard heaters, or buying their heaters also.(They are pricey). Any thoughts would be appreciated.

an interesting twist Redsy, yet the standard 250W per ft barrier remains unbroken for colder days

Come on, now! I know you can do it [Linked Image]
Proportional control is popular in industry to tightly control processes such as temperature, level, flow. etc.
I'm thinking SCRs are used in the proportional-type thermostat to operate the oil filled heater. If this is the case, I can't see why I can't operate standard heaters.

The brochure says that it controls up to 4000watts so I see no reason why it couldnt be used to control your other heaters as long as they dont exceed that.I'm trying to find the UL listing on it.Their brochure also says that they can be used to replace old thermostats,but it doesn't say on what.
Hey they are telephone controlled too!(another line to run)

Mines telephone controlled too,if the wife is home to answer it. [Linked Image]
