    Default More cabin heat?

    VT Glen and I spent some time Sunday comparing notes on cabin heat, the lack of it. It was 0 degrees in Maine yesterday morning, its a bit "sporty" in the heat dept. Anybody have a breakthru on improving heater output?

    thx

    I am planning on getting a heat muff for the open exhaust. Adding an inlet on the left front ramp to the heat muff then from the muff to a Tee near the control box. I am hoping this will help. Parts are on order so it will be a bit before I know. Just concerned that the muff will not have enough clearance on the forward left stack to the cowling. There is a chance that the stock one will not even fit on the exhaust.

    The other idea is to tie air from the plenum which should have more pressure and create more flow. I think the lack of air flow is the biggest issue. That scoop does not work.

    Right now at -10c I can still just see my breath. The heat doesn't do much.

    Planning on uncowling the engine tomorrow to cast an eye on the whole cabin heat system. It was better in afternoon when it had warmed up a bit. OAT of 0 and below the heater is pretty weak
    keep us posted if you make changes

    Would wrapping a layer of thin insulation around the two muffs be of any value? Perhaps header wrap? With zero degree air blasting past those muffs it seems like insulating them could be of some value. Cheap, light and easy to do.

    I would think that CC would offer this as an option

    I did some measuring last night I agree with you, its going to be really close to fit another muff on that left pipe, I think it will hit the cowl Please post some pix when you make the mod.

    Millwaukee heated jacket. Works great, has 3 heat settings. Ive been wearing it everywhere. Red is a poor choice for a guy who cant stay clean. The jacket rocks, lasts 8 hrs on low.


    I have made a couple of passes at more cabin heat with some real good results. I flew this morning for 1/2 hr at sunrise 5 below zero, the cabin pretty comfy. Not overblown yet, but were getting there. Will post up my changes when I get the thing where it looks good and works better. There is hope yet to fly with no gloves and hat.

    You'll need a DeWalt one if you want it to match your plane
