General Outdoor Furnace Discussion / Adding storage questions
« on: January 10, 2018, 05:21:14 AM »
I have a natures comfort ncb80 which is only 80 gallons. It has been doing a fine job heating the living levels of our home and other than crappy pumps and a sticky aquastat I have no complaints. I have ordered a grundfos alpha to replace the constantly breaking broeder pump and a new aquastat is on the list. This coming year I intend to add a HX to the basement that is now a shop/office/laundry space with a half bath. I also intend to heat a small outdoor shop that is really just an oversized uninsulated shed. I live in the north GA mountains so my heating needs are not as extreme as you folks living up north, but the wife likes it 72 inside all winter long.
Up to this point the boiler has only been used in the winter, but I intend to begin using it year round to heat DHW.
I am sure that with the added heated space and only 80 gallons my run intervals will no longer be in the 12 hour range and I think I should be adding some extra storage.
I have a spare 300 gallon LP tank sitting in the pasture doing nothing, so I'd like to use it as hot water storage. I will build a small insulated enclosure next to the boiler, but I am unsure how I should plumb it into the loop and where I should install my inlet and exit pipes. I have a space on the boiler for a second pump, but I am not sure if circulating water from the boiler to the storage and back to the boiler is good or if from the boiler to the storage and then out to the house and back to boiler is a better option.
Thoughts and opinions ??

Plumbing / Dhw question
« on: November 06, 2014, 03:58:45 PM »
New user..... not running long but I have a small issue with the hot water.
I have my mixing valve connected to a manifold and distribute the water to two hot water heaters from the manifold. One water heater is a very small (maybe 15 gallon) unit that serves a small bathroom and the other that is upstairs (30 gal) serves everything else. On days when no one is home the water in the hot water heater cools down and the water coming to the house is like 50 deg. It takes a long time for the hot water to mix with the cold in the hot water heater and provide hot water.... after it is hot in the tank it is fine but waiting 5 minutes or more to get in a shower is not okay.
I have two empty ports on the manifold and I am thinking about running a line to the hot out side of each hot water heater to get my more instant hot water.
I plan on leaving the hot line on the cold fill tee as well. I don't see an issue here but I'd rather ask you folks first.
Thanks in advance

General Outdoor Furnace Discussion / First Fire this morning
« on: November 01, 2014, 09:30:50 AM »
Well I fired up this morning. Good thing since it snowed all night. Its never good to have snow this early in GA.
Everything appears good..... I have hot water and heat but only low speed on the fan. Still nice at warm.... no check for the LP man!!!!

General Outdoor Furnace Discussion / New OWb owner just saying hello
« on: October 26, 2014, 11:24:18 AM »
Just thought I would say hello. I've been reading(researching) here for a while but did not post.
I purchased an NCB 80 in the spring and am just now getting to the install. I posted in the Natures Comfort forum as well but thought it would be a good thing to say hello here as well.
Like so many new owners I jut don't want to pay the LP gas man anymore and learned that time was probably running out to get my OWB without having to spring for a gasser. Providing I don't buy LP this year the OWB will be paid for in Full by the start of next heating season.
aprox 1700 sqft
forced air HX and plate hx for DHW ( family of 5 and long showers )
I've got 5 cords split and dry with a few more waiting to be split.... I live in North GA so I'm hoping this will be enough for the winter. I'll try to put up a two year supply next year based on what I use this year.
Next season I hope to have staple up radiant completed, but this first season will be just forced air.

Natures Comfort / NC 80 install finally underway
« on: October 26, 2014, 10:56:58 AM »
I've been reading here for a while but have not posted yet. Figured its time to participate. I purchased the 80 in the spring for a great price.... dealer old stock.. needed it moved blah blah...
I originally had my heart set on the smaller ridgewood, but this one came up at just over $1200 cheaper with HX,pump,Plate exchanger, mixing valve, insulated pipe and enough 1 inch pex,fitings and clamps to cover my installation.
Anyway.... I poured the slab and buried the lines in early summer and had a friend with a skidsteer get it off my trailer and set on my slab. After the flurry of work, life put the brakes on the project for several months. A few little cold snaps have inspired new activity.
Well yesterday I cut into the forced air system to install the HX.... that was harder than I thought it would be. I ended up with my manifold, feed and return lines inside the air return and the rest of the HX 2 inches above the ac coils. It has made for a fairly stealth install though. This week I will run the lines back to the plate exchanger and punch through the exterior wall to make my final connections.
I have some new hot water lines to run as I will be feeding 2 hot water heaters and will be running an exterior hot water line to melt ice and snow from the car this winter and to feed hot water to my pressure washer.
That's it for now.... I should be ready to fire it up in a couple weeks and I will try to update often over the winter as there seems to be very little information on this small unit and I'm sure someone will be interested.
