in THE MAIN WALL
I've attached an email from Field Controls. The web site shows the unit, but the project manager indicates it's not ready yet. I'll pursue this a bit more and post the results. Mark S


At this time there is not one on the market available, but we are in the process of building one. It is still in the test phase, but we are hoping to have it available for this heating season.



Thanks,

Does your company make an automatic flue damper (similar to flue rcvp ksf/pcf) specifically for use with oil fired boilers? Or if not, could you recommend other options to minimize boiler standby losses. Oil is getting expensive. Thanks , Mark Schofield

    I have a poor client with a tankless coil in her boiler, so the boiler must run all summer to give her domestic hot water. She only needs the hot water for an hour in the morning and another in the evening. But the unit is hot and heating the world thru the chimney all day. Is there some way to close a damper and then have it open when the unit wants to fire?

    Flair used to make stack dampers

    for oil-fired units, but they went out of business some years ago.

    What burner is on the boiler now? I believe some Riello models have automatic air inlet dampers.

    Try Effikal

    They make them pretty much for the industry. I'vehad one on my Buderus G224 for 8 yrs with no problem. Not sure of the service requirement for oil

    Those might be out of production

    they don't appear on the Effikal site.... too bad, with oil prices the way they are I bet they'd really sell......

    Field controls has a new product listed on their web site. A damper secific to oil fired boilers. And a link to a Youtube promo video for the product. Here's the link to their site.

    Sure looks like

    an Effikal to me, Field must have bought the rights to it.
    Thanks for the link Mark!

    switch

    Why not just turn the boiler off?

    A boiler that has always sat at 140 - 160

    and then goes cold will most likely leak at all its seals.

    liability

    Anytime you install a component or appliance that is not tested and listed for use with that specific appliance, there is a transfer of liability or an assumption of risk on the part of the installer and the wholesaler. You can reduce that risk by getting a letter from the mfr. of the boiler approving the devicebut good luck with that. Just understand that just because products are made does not mean it is always a good idea to use them. In this case, ask yourself, if this was such a good idea, why don't all the mfrs. approve them or even ship them with their units the way many gas mfr.s do? Or, why don't the mfrs. offer automatic vent dampers as a listed option? Contact their technical services dept.

    i have cast iron boiler i run every other day for hot water & temps vary widely between firings. no leaks. i've read condensation in cold boiler may promote a corrosion problem.

    If

    the manufacturers and standard-setting bodies approve certain devices for retrofit use, which may or may not involve certain prerequisites (such as redundant gas valve when using a damper on an atmospheric gas boiler) they should so state in their instructions. If they don't, I'd be wary.

    Every stack damper instruction sheet I've seen states that such use is permitted. Same with spark-ignition upgrades (as Honeywell Y8610 series) and replacement oil burners and gas power burners.

    Many boiler manufacturers offered stack dampers on their oil-fired boilers during the first couple energy crises. But they cost a few bucks, so people quit buying them when oil prices went down. That helped put Flair out of business IIRC. Also, when used with older non-flame-retention burners, the dampers tended to get sooted up and stick, which resulted in a no-heat call. This issue could be dealt with by specifying that such dampers only be used with flame-retention burners.

    I still have the Flair Stack Pack that came with my Burnham V-14. It has needed to be lubricated a couple times but otherwise works well.

    That was

    the direct link to the video, instead of going thru Field's site.

    A vent damper

    on a newer oil fired boiler may, or may not, pay for itself or compensate for potential, and actual, maintenance/replacement costs.

    New flame retention burners have very small openings, (unlike wide open atmospheric gas units) which impede off cycle draft loss thru the burner, & up the stack. A properly installed, & adjusted, barometric further reduces stack losses.

    Want to reduce standby losses. Look at how the Euros insulate their boilers. Add some insulation where you can. A few dollars of pipe insulation around the boiler will help too.

    Thanks for all the help. I'm proposing the Field damper to the HO in the AM.
