Solar Baseboard

Bestway_Dave Member Posts: 4
I have had good success tying solar with baseboard in with high efficiency boiler backups. This works when using outdoor reset controls and baseboard design that can meet heat loss at lower temps. I have only heard bad things about intergrating solar with high temp baseboard and high temp boiler backup. Has anyone had good success with this?

    if you can get

    enough BTUs to the room with the solar temperatures, go for it.

    I saw a nice convector add on recently. Jaja is building a row of small quiet "muffin" fans to fit inside their panel radiators. They sit right on the fins. This allows a much better output, allowing them to run with supply temperatures as low as 90F.

    The "group" of fans is controlled by a small circuit board the provided temperature control and indoor reset function! Should be a great match for solar hydronics. I believe the assembly is in the listing agencies as we speak. I'll dig up some pictures.

    Solar Baseboard Deja Vu

    Here's how we did it in 1982, sort of a vacuum cleaner attachment for a shaded pole fan. It was cheaper at the time than a row of muffin fans (which sound great).

    Also attached is a discussion and calculations showing the increased btuh output.

    how much electricity do you use?

    I am often concerned about saving on one bill and costing on another.
    Cost is what you spend , value is what you get.

    up to 300% output increase

    the fans run on 12V dc, nice for off griders. The boost will be available for various types of rads. 25- 75W at full speed, I think.
