I am hearing about poor heater performance on the Honda heater. Excellent when sitting but when moving not very good. Temps are zero.

Anyone hearing anything

I would think for winter and cold you would want to cardboard off some of the radiator?

Since a heater is just another radiator and cools the system even more.

An electric with an extra battery might be the way to go?

the summit heater I installed works great. BUT It's on a Honda though. You need to warm the thing for a freaking hour to see 2 bars on the temp gauge. It would be a fine idea to block off half that radiator.

I'd also be curious to how many still have air in the heater system.

Sometimes these remote radiators are hard to bleed all the air out.

I used to deal with some old mules and they were a PITA to get the air out.

The Honda instructions have you filling the heater core and the hoses before you attach them to the vehicle. Seems pretty serious about getting the air out.

Yep, that's the way it should be done, but I know a heck of a lot of people that would do it "a better way"

Installed my Honda heater today. Not much heat output. I blocked off the entire radiator…..only got two bars for heat despite a super long ride and wam up.

I can feel a small amount of heat coming from the ducts….but you don't want to leave your gloves off too long at 0 degrees f.:eek: Never really warmed the cab…..and you could see your breath after an hours ride. I doubt if I raised the cab temp 2 degrees.

Disappointed? Yep. :(

Think it's possible you have any air in there Foggy? Did you try elevating the front and removing the radiator cap to make sure she has a good burp?

You are the 4th confirmed heater ain't worth it that I have heard......

Didn't try any "burp". Maybe tomorrow. Not much heat output the way it is. Drove it for an hour. Maybe I got air….dunno.

Cant get the heater past two bars despite blocking the entire radiator. Got cold…..had to come in.

Sounds like you still have air.

I've been riding in much warmer weather than you guys, and I've never seen the temp gauge go over 2 bars. Ever.

You've just effectively added a second radiator, so the warm up will probably be longer than before since the heater still dissipates heat even when the blower isn't on. And for that matter, leave the blower off until it comes up some.

I've given up waiting for the appropriate bar reading to take off. Below zero, I give it 10 minutes, I just can't wait all day. It will still be reading lo 1/4 mile down the trail.

I wonder if a couple of bypass valves to just run the coolant through the heater and not the radiator. Probably be plenty in the winter and you could shut the heater off in the summer?

I have 3 heaters sitting on the floor waiting for machines to come in so I can test them out. The biggest issue I can see (I haven't even looked at the install directions yet) is your pulling the air from the outside and trying to heat it rapidly. When it's cold the air isn't going to heat very fast going across a small radiator resulting in poor heat output. I could be wrong on this and maybe the heater core is getting hot enough to compensate for that.

I have installed the "in cab" heaters before and they work awesome. Of course they are just circulating cab air. I have my other customers waiting at the moment to see if these Honda ones are going to be worth the money.

I know the heater in my dodge doesn't get warm unless it's above 30 degrees, it's a POS though.. lol I'm hoping one of my customers will bring me a machine so I can try it out though and have some first hand advice/opinion on it.

Well, I've gone thru three good warm-up phases with my Pioneer heater…..and still have no heat to speak of. The lower radiator hose is hot, I have the radiator completely blocked off with cardboard, and I get two bars on the gauge.

I must have an air block? The fan blows cold air. I did follow the instructions from Honda and pre-filled the heater core and the hoses before connecting them.

I tried jacking the front up with the cap off overnight. I dunno. Today the air coming out of the heater vents is cold as ice after 1/2 hour + run time.

Advice on purging air from the heater core? Wish I had a squeeze bulb to circulate the antifreeze solution thru the heater core.

Foggy,

Sent you a PM with some things to try.
