Switched supply/feed lines
« on: January 08, 2015, 05:51:07 PM »

I have a sneaking suspicion that the man who installed my wood burner switched the supply and feed lines accidentally what is this going to do to my stove and how can I fix it

What does your stove supply water to?

My set up is the similar, Dhw plater hx pand water to air heat exchanger in a gas forced air furnace.  The supply should go through your filter them to the dhw exchanger and then to the furnace. If it is hitting the appliances first you could run into issues with clogging. Where is your pump located?

Sounds like my supply is going to exchanger on furnace first then to the plate exchanger above water heater then filter.  This means the supply is connected to the wrong side of the condenser going into furnace.  I'm having problems keeping my house warm and I assume this is why!!

Have you looked at the back of your unit (boiler) to see how it is hooked up?

All looks good on the back of unit. I can feel difference in temp on the two lines in the house.  The return is hotter than the supply line.

 :pic:
if you can take a picture of the back of your stove and your house connections and lines and post it so we can see how it is hooked up,  best way to post is use Flickr or photobucket and post the link to the pics here. Also not trying to be a smart guy but have you compared the hookups to the owners manual?

I will try to get pics.  Think about this, when I bypassed the filter to clean, I turned it back on and could hear the water circulating the wrong way through the filter.  Water is coming from the house to the filter instead of coming from the boiler to the filter and then the house.  This is telling me the lines are backwards.  Sound probable?

It very much sounds backwards.  My guess at this point is that the pump is on the wrong pipe at the back of the boiler. This can make a huge difference in your flow rate (gpm) as these pumps are designed to push and not pull the water. It should be feed by gravity from the water jacket son the boiler then push it back after running through the house.  The links are what it should look like on the back of your boiler.

First attempt to link pics so let me know if you can acces them.

I got your pictures and my connections look correct in the back of my boiler my next guess is that the pipes underneath the house are switched. The two lines from my boiler connect to the two lines in the my house inside my crawlspace and I'm thinking that is where they are switched

I'm trying to send you pictures on Flickr and can't figure it out I did crawl under my house and I can see that the feedline is connected to the wrong line. The supply line is clearly connected to the return line underneath the house what is going to be my best option as far as draining the system and switching these lines?I would send photos but like I said I can't figure out how to do it but it clearly shows that the lines are crossed what is your input as far as what this is doing to my entire system am I screwed?

Are all of your hook ups ( furnace and HX) in the crawl space?  I would think you could shut of the power to the furnace and close the valve on the back of it' then just have to drain the lines themselves. Make the switch back and then refill the boiler open the vales and allow the air to move out for about 5-10 minutes then restart the pump.  PM me and I will send my email address so we can possible trade those photos.  We will get you going.
