I am considering an outdoor type wood burning furnace to heat my house. It is presently heated by oil hot air. If you have an outdoor furnace, has it met your expectations? What make do you have? How often must you add wood? How much wood do you burn/year? What is the size of your house?

Get yourself a heat pump about a 18 ceer. the wood stove you are talking about will burn a 1/2 truck load of wood a day,and you will need a place to put your ashes everyday the only way you will save money with this stove is if you don't work and have a lot of time to cut wood and keep the fire going and you can't go anywhere because your fire might go out and all your water lines may freeze. If you do need to go some place over night or for more than 1 day you will need to hire some one to come to your house and put wood in your stove and take out your ashes. That sounds like to much fun for me, knock yourself out Paul Bunion I admire your drive to save a little money.

I just purchased a central boiler outdoor furnace. wondering when hooking up to the water heater if anyone can tell me if they have problems with it ? I am thinking the tp valve may kick open due to the temperature of the water coming in from the furnace. I am thinking of hooking up a zone valve on the return side of the coil in the furnace to bypass the coil when heat has ended its call on the thermostat. any ideas of hooking up would be appreciated. Also thinking of something to turn the fan on when heat is being called for. Please let me know your setup with central boilers.

Go to www.centralboiler.com and then go to "HOW IT WORKS" on the left side of the webpage. There are many detailed installation illustrations available on this website. For more detailed installation illustrations go down to "More detailed variations..." Are you using a shell/tube side arm heat exchanger? The only way the tp valve will open is if it fails/faulty or if it is not rated at approximately 200-210 degrees F. Remember, the water from the furnace never mixes with the water in your water heater (i.e. side arm heat exchanger). The water coming in from the furnace is 165-195 degrees depending on your desired setting. Check your tp valve, there should be a silver round tag on it that tells you what it is rated for in degrees farenheit and this should answer your question on the valve. I just checked mine and it is rated at 210 degrees F. Sounds like you are also connecting it to an existing forced air system. If you install the system as recommended, your fan will come on when heat is needed. Make sure to read your owner's manual. You have available to you several tools here, you can also contact the dealer that sold you the furnace or Central Boiler directly if you have any questions on the illustrations they provide.
