Many factors, nobody is the same 1800 living area??also direct plumbed from 1450 to oil boiler no exchanger,hot water coil in attic of new part with air handler old part radiators,domestic hot water 80 gal,old and new house did addition half is new of the 1800 both have insulation the old side 1853 circa,it maybe more than 1800 sq ft. Used CB flex underground pex.the biggest part I learned was not to go bigger than needed you want the unit to cycle mine does about 1 to 1.5 hr burn cycles.i wanted bigger but Sunshine tree and landscape that sold it to me had to order so they weren't pushing it on me said it was big enough and is very well suited for the job,they could of made some money on me because I wanted bigger they said don't need it and it uses little wood! I'm not new to wood boiler heat had one in basement for 18+ years heating same house or trying to!

So do you think that connecting it direct without a exchanger makes that big of a differance I just ordered the 6048 but I am currently running through a 70 plate exchanger should I consider running it direct boy I'm confused I thought I had it figured out now this!!! Oh boy

Not sure it was the way I was able to do it and less cost of exchanger,my house system was filled with cryo teck ant corrosion additive when I hooked up the other wood boiler in basement long ago and system was clean clear no rust! Not sure on the loss if any but would think there would be some also I think one other circulating pump on house side needs to run constant?

that's how the central boiler said he has his too direct from boiler no exchanger.. Did you ever have run you other boiler (oil or gas heat)if that one went down? Trying to figure out the open system of OWB compared to existing closed system if I were to turn my propane boiler if it would matter

There is a thermostat. Valve on the loop from outside if temp goes under 150 it shuts n circulates just the outside so oil inside is not trying to heat that

[aries9245]

Ok interesting....

[5050racing]

You set oil at like a 150 so it will heat the house if fire out or u gone away to long,plus CB doesn't want the boiler to get cold n hot back n forth not good for condensation in firebox

There is a better way to control the oil boiler!

[aries9245]

I'm just wondering about hooking the boiler direct compared to exchanger would I need a circulator inside too if it's hooked direct.. And what if the propane boiler goes on what stops it from heating all that water in the owb.. I don't mean to sound dumb it's alittle confusing and I don't want to make another costly mistake..

what's the best way to control the boiler?

[slimjim]

Monitor the incoming/supply wood boiler water temp with an Aqua-Stat, use the break on rise terminals to break the power connection to the burner motor, set the Aqua-Stat @ 160 degrees, any time the supply is over 160 degrees the burner cannot fire but below the setpoint, your oil boiler returns to exactly the way it was before you had a wood boiler.

Sounds great how many sq ft is it heating?

approx 1600 sq ft house with 800 sf ft basement

[5050racing]

That sounds good with aqua stat maybe do that one day
Guess a strap on one would work so not to break system open

[slimjim]

Honeywell strap on 6006C-1018

[5050racing]

Sounds good always learning,don't really let it switch over someone's always here but still a good idea will instal one day

There is something about this crap that I really enjoy I don't if it's the challenge of doing something I've never done or just the great feeling of success and screwing the oil and propane companies.. I think that's what I luv the most not paying that bill any more.. And all of you here make it a pleasure to be part of something great.. Thanks all
