Plumbing / new install
« on: June 23, 2014, 07:35:29 AM »
Ok here is my situation. I'm looking to install a new outdoor wood boiler for our dairy...........going to run in conjunction with solar hot water panels on the roof
One company who is quoting the install says I need 3 pumps the other company quoting says I can get by with one pump
Here is what I'll be running
Solar panels
hanging heater
pasturizer
hot water heater
how many pumps is enough?

6 gallons per day (x) 5 cows = 30 gallons per day
30 gallons x 7 days =210 gallons per week
make cheese 3 times per week.....so 3 batches of 70 gallons
cheddar cheese takes 116 degrees for 30 minutes......aged for 60 days to be sold
or
140 degrees for 30 minutes if we go with pasteurization
We will be making cheese in a stainless steel kettle that has a water jacket .........water in and around the kettle and back to the loop
Alot of the stored hot water will go to clean up / wash down. Which will be used twice a day every day
30 gallons x 7 days =210 gallons per week

its not as big as you may think .......we have a 5 cow dairy and make cheese. cheese room, office, wash up room etc is only 18X24.......looking at around 160-200 gallons of stored hot water

RSI........ This is not for a house its for our dairy. Heating a cheese making vessel and a cheese room and hot water to clean up......ok and possibly a greenhouse at a later date

We are looking for solar hot water panels ..........in NC you can get 30% tax credit for solar hot water panels and you can use wood furnace as solar storage and back up

I'm wanting to install solar panels and backup with a wood furnace. I'm looking for someone in NC or SC that sells and installs these units together
any ideas

I'm with johnybcold...........dont focus so much on getting more heat until you have exhausted all efforts to reduce the need for heat.
I insulate the north walls of my greenhouse to help with loosing heat. I'm also in the process of adding thermal (water) storage in the greenhouse. I am burying an insulated water tank under the greenhouse to help hold the heat in the greenhouse. Lots of passive solar houses add barrels of water on the north wall that cool slowly and hold heat in through the night.

General Outdoor Furnace Discussion / silly questions
« on: December 17, 2011, 04:36:47 PM »
1)Everyone always talks about measuring return heat why is it important for the temp returning not to be to low?
2) why use a heat exchanger in domestic hot water........why not just use the water out of the OWB tank and plumb the local well up to refill the OWB when water is used out of the OWB tank? My domestic hot water tank is only 80 gallons ........the OWB is 750 gallons
Thank for entertaining the silly questions of a newbie

Jackel,
Plan on using a heat exchanger in the tank or just pumping out of the tank and returning to?

My philosophy (right or wrong) leads back to theories of passive heating a greenhouse.............to stabilize temperatures at night you add water that is heated by the sun during the day and released at night. The more volume of water the more stable your temps are
@martyinmi
shouldn't you be able to keep a small fire burning constantly so the storage water does not drop to low? feed small amounts of wood 2 times per day or large roaring fires every other day.........i would choose to maintain a small fire daily so you don't work the system hard every other day
I don't have a modern gasifier........i have an older taylor.....I would assume you wouldn't want to mess with newer gassifiers as much

thats part of my question..........if i keep it all as potable .........then i suppose i'll run a loop from the furnace (out the hot water loop) to a heat exchanger inside the large tank.
if the heat exchanger idea is to much ..........then i'm looking to just run a loop from the furnace ........pumped to the tank and back to the furnace

Scott for my application it will not work
I'm putting the 8000 gallon tank below a greenhouse with the idea that the heat from the tank will rise and keep the greenhouse warm. I was also hoping to used the hot water from the tank as potable (not sure that is feasible yet)
The whole idea comes from a passive solar greenhouse design where you store water in barrels inside the greenhouse to minimize temperature swings overnight.
Ideas?

I'm wanting to do something similar.
I have a 8,000 gallon tank with a pressure bladder that I plan on insulating and burying in the ground. I want to use it for potable hot water storage. Would putting a heat exchanger in the tank accomplish the same effect for storage (ie shorten run times, and increase thermal mass for the out door wood furnace?
or would the tank need to be plumbed into the furnace so that it all could circulate........if so i would have to find another storage system for potable water
