Site Suggestions / Current manufacturers producing epa cert furnaces!!!!
« on: October 01, 2017, 08:02:45 PM »
Hello moderators.
I have people ask questions sometimes on some furnaces that are no longer in production. Even though they are on the EPA certified furnace list. I'm sure people are wasting time looking into these furnaces and where the nearest dealers are. only to be frustrated further by finding out they do not manufacture or are out of business.
Can we get a header in for current manufactures you can actually buy from. You can word it how ever it makes sense. Thanks. Then lock it so there is no jiber Jaber on it.

Yes Marty people always take short cuts when possible (human nature) 30 /40 deg you can get away with mistakes. When it is below 20*F is when the problems show up. I don't know what the statistics are but a lot of people don't come on this site until they have a problem. then the problem solvers come on and try to build a system in their head from the partial info they posted.
Seems that more new people are coming here before purchasing and are trying to get good information so it will be done right the first time. Kudos to them.

I hope it doesn't show its ugly head when you need it the most.

No Honda it is not about a particular brand of furnace. It is about bad installs that can make any furnace look bad. Or under perform. So if you know of a bad install that might help someone out of a jamb. You can post it here. Also was asked to remove the hawken post which I did. Sorry for any confusion.

Was looking threw the hawken boilers and came across this posting. Was hoping that someone picked up on it before it came to the end of story. But they did not.
So when a heat exchanger ️(HX) is hooked up wrong it will make any boiler function poorly and work harder to get the results it is rated for. We all know this to be true.
So in this post the ️HX is hooked up in parallel flow. Example. 180 from OWF 150 from house. Heats to 165. ( Acts like it is mixing instead of transferring heat.) 165goes to owf 165goes to house. Thus your zones are starving for BTU's and your boiler is working harder n longer. To get to the shut of temp.
The correct way is the counter flow.as we all know So the incoming cooler house water warms up to the 180 or close to it. And the return to the OWF is cooler maybe 155deg water so it can absorb more heat energy. Your house will come up to set temps sooner and then let your OWF come up to the shut off temp sooner.
In this old hawken post, the same thing still happens to a lot of customers still today.with any boiler.
Hondaracer was on track with the ️HX. What do you guys say. ??

@hondaracer2oo4 and @ woodman It is snowing big time outside and we have a bunch of wind... so the temps are for when the zones are calling for heat... BRRR wicked cold out right now.. so this is what I got for ya. Water jacket temp reads 172 on the front of the unit. The supply line on back of furnace measures out to be about 165 and the return line 139. Inside the basement about 75 feet or so the lines measure 163 and 137.
The lines across the plate exchanger measure 165 135 on the Furnace side and 137 121 on the house water side.
Air temp inside the house is 68
Is this what you needed to maybe help? Did I miss anything?

Plumbing / Re: Opinions on using pex pipe less than 1" inside diameter

Takes more energy to push the same BTU threw the smaller pipe over 20 hrs it adds up.

Two other thoughts if your TT is jumped ,make sure it's a good conection.
Also may be the electrode gap. Maybe losing the electrical arc if it is to much gap?

Well ,when it is running wiggle the wires and tap on the electrical boxes. Chances are it is close to the burner. If you take off the wire nuts the copper should be twisted together.

Roger.
If the tank is not low on fuel. Could there be water from condensation ? Check all electrical conections. From breaker to the emergency shut of switch to furnace and all the grounds back to the panel. What kind of burner is it? Becket , Riello , etc. what is the primary control?

HeatMaster / Re: Temp readings over heat exchangers
« on: September 13, 2017, 08:10:52 PM »
You guys are wasting your time and money trying to figure out who's stove is 100*deg cooler. There are to many variables to the puzzle. If the water temp is at 150*F. It's going to be a cooler reading than if at 175*F.
I know one thing for sure most gasifiers are better at capturing heat than the conventionals.
So a six inch heating duct moving 100*F air at 60 cubic feet per minute. Equates to what in one gallon of water temp btu == sh!T.
X 60 min = maybe two sh!T =which is one piece of wood.

That's a lot of work to do. If possible I would set up radiant floor heat.
And forget about the hot air coils. To much going on there.

Frozen.
Grundfos has the alpha 15-58. It is a very good pump. I have one in my system. It has 7 settings
3 pressure.
1 auto
3 flow.
It has a lite digital display that toggles back and forth between watts and gpm. Letting you know exactly what it is flowing and using for energy. Very easy to change settings. Just push the desired setting.
