Portage & Main / BL 34-44 chimney and boot
« on: October 22, 2020, 08:00:27 AM »
I am in need of a chimney extension (approx 3-4 feet) and some sort of a weatherized boot to put through a metal roof.
Does anybody know what brand of chimney was used on a Portage and Main BL 34-44 built in 2017?
Looking put the stove under a carport with a metal roof to keep the wood dry.
Suggestions on the best way to do this? What Boot/Chimney works best?

Looks good. What kind of "sleeve" or "boot" is used to put the Chimney through the roof?

E Yoder is there a particular way that you attach the sensor from the Ranco to the pipes? I have it zip tied and electrical taped to the pipe but it is reading about 25-30 degrees lower than the temp of the pipe.

The air handler does have a variable speed blower. Drawing changed.

Would I also need to break the brown wire for the emergency heat after the block for the same reason?

Thanks

Thanks E Yoder. I like the idea of the Ranco Temp control. I did not think about the problem of bumping up the temp to fast and the emergency heat kicking in. I changed  the relay to a DPDT. I'm not planning to run it in the summer so at this point I wouldn't need a switch.
New drawing attached.

Naturally aspirated with the nest thermostat can I have the first stage of heat be the outdoor wood boiler? I currently have a 4 heat 2 cool White Rogers (1F95EZ-0671) thermostat and was told by tech support that the heat pump had to the first stage of heat. Is there a work around for that with the nest?

Thanks for the input.

Electronics / 1 thermostat for heat pump and outdoor wood boiler

I have seen this mentioned in some of the older threads but wanted to start a new one in case someone else is looking to do the same thing.

My house is currently heated with a heat pump and Backup electric strip heat in the plenum that comes on automatically if the heat pump cannot keep up.

I have looked for thermostats that would allow me to have the wood burner be the primary heat source and the heat pump as second and electric strip heat as third with no luck.

I came across an old post from Schoppy and he basically did what I am looking to do by using an aquastat.

If the water coming in the house form the OWB is hot then a call for heat from the thermostat would start the secondary loop circulator and the blower in the air handler. If the water is cold and a call for heat then it would send the signal to the heat pump and blower to start just like it is currently wired today.

Am I missing anything with this?

All the solid colored wires and the dashed yellow line shows how the thermostat is currently wired. The proposed (yellow) wiring goes to an aquastat to direct the signal to either the circulator or the heat pump.

I do not think I need to do anything with the (reversing) O/B terminals.....?

I have a Honeywell programmable T-stat for my system but don't have the model number handy. It has multi stage and emergency heat capabilities. I used Geothermal for my primary heat source and LP for backup before I added my OWB (which was mainly for a new shed) but I decided to put all my heat loads on the OWB if I was going to keep burning wood. I didn't change anything regarding my T-stat with the exception of adding a strap on aquastat to my supply pipe set at 120 degrees which interrupts the 24 volt line to my geothermal contactor.

As long as the water temp is above 120 (or whatever temp you want) the T-stat cycles the furnace fan on as normal. It doesn't know or care that the geothermal isn't doing the heating. When the temp drops below 120 the contacts in the aquastat close and the geothermal kicks back in. Has worked flawlessly for me.

Schoppy do you have any pictures or diagrams how you have this hooked up? This sounds exactly what I have been looking for.
I currently have a heat pump with electric strip heat at a backup but want to use my OWB as the primary.

Plumbing / Re: Another side arm vs flat plate question.

Has anyone done anything like this? Would it work?

Plumb in the lines to the water heater like normal and dump cold water into the tank.

When the temperature inside the tank gets low enough it would kick on a pump to recirculate the water through a flat plate heat x-changer instead of kicking on the electric element inside the water heater.
Pump would then kick off when tank is up to temp.

Plumbing / Another side arm vs flat plate question.
« on: October 04, 2017, 08:26:27 AM »
This topic has probably already been beaten to death over the years but I have looked in some older posts but have not found what I am specifically looking for.

The question is regarding heat x-changers for Domestic hot water heaters

From what I have been seeing there are 2 types.
Side arm and Plate.

Below are a few assumptions I am following........ Correct me where I am wrong.

Side arm :
Pros-Good for keeping hot water inside tank hot.
Cons- Any new water added to the tank will be cold. Not good for large amounts of hot water.

Flat plate:
Pros - Heats water when adding it to tank.  Good for large amounts of hot water
Cons - If hot water is not used frequently water in tank will cool off.

Is there a way to hook up a heat x-changer to be some sort of hybrid? I would like to be able to use large amounts of hot water and keep the tank hot when not in use?

Use a flat plate to dump hot water in but also use it to keep it hot?

Does it make sense to have both a side arm and flat plate?

Calefi book.


Smokeless this diagram looks interesting. Is this something you got from Caleffi or made yourself? I would like to get some more info on it.

Thanks

Than you for the detailed response.

I have been calling it an outdoor reset but what I think I mean is an automatic thermostatic mixing valve. I want to lower the temp of the water running through the concrete loops on warmer days and raise it on the cooler ones.

I am on the same page as you on keeping the boiler water at the high temp all the time.

I was hoping to use just one valve for multiple zones to try and cut down on the cost.

I am looking at your diagram for your dog kennel and have a few questions.

The primary/secondary loop going to the house and towel warmers makes sense to me but can you elaborate on the other loop going to the garage and dog kennel?
It looks like there is a mixing valve "ZV999" just after the pump in the primary loop..... and also one before the pump "TMV999" in the secondary zone.

Also do you have a special software to make these diagrams or just using autocad?

No problem on correcting my errors. I only want to do it once!

I modified the drawing to show a series primary/secondary loop rather than the parallel that I had originally drawn per the recommendations. Drawing attached. Does anybody see any problems with this layout?

I am still struggling to envision how I can use one outdoor reset to control the water temp for 2 different radiant heat zones.

The outdoor reset that I have seen in the past is one from Viega. Attached picture.

Thanks

Maybe I am calling it the wrong thing. I had seen one at an outdoor furnace dealer where they had what I thought was an "outdoor reset" hooked into the plumbing before the radiant manifold. It controlled the mixing valve to give warmer water on cold days and cooler water on warm days.

I'm struggling with how the plumbing would be setup to have 1 of them control 2 separate zones with 2 pumps without doing a tertiary loop.

Any ideas on how I would control 2 concrete zones with 1 outdoor reset?
