Plumbing / Re: Friction loss 1 inch to 3/4

Thanks Scott. Seemed to make sense but I needed a professional to keep me straight.  I'm still attempting  to design everything so it's somewhat right and this info sure helps.

Plumbing / Re: Friction loss 1 inch to 3/4

I'm trying to accomplish the most heat to each unit. Both are on there own circulater from the heat exchanger. Two loops one for each 100k unit. Also a very small baseboard loop from a different circulator from the he, maybe 10 k at the most.

My question is it better to spend a few more dollars to go with 1 inch or does it matter at all and just go with 3/4"?  All this is from the he to the blowers. Nothing with going back to the OWB.

All this would go from the he to a manifold to the pumps and then out.

Thanks

Plumbing / Friction loss 1 inch to 3/4

« on: September 01, 2013, 12:10:57 PM »

Afternoon all, I have a question about going 1 inch to 3/4 out of the HE. I'm going to bring 1 inch to the HE from the OWB. Then run out to two 100k garage fans. Each will have its own circulator.  My buddy has the same set up. When he came out of the HE be went to all 3/4 to the blowers. I was going to use 1 inch thinking more flow would be more heat. I don't mind the extra few dollars for larger valves, lines, fitting, etc. am on the right track or does it matter?  They are 100' round trip from the blowers with eight 90,s. 12' vertical head and was thinking of running them with a taco8.  I may be overthinking this but I do a lot of friction loss calculations on fire hose the same size and it matters quite a bit.

Any thoughts would be great.

Thanks

Thanks All.  Great information and should make getting the right one easier.

Do I need to calculate the friction loss from the house to the OWB for a pump? The elevation difference is roughly 5 feet up but then you take out the height of the pump on the OWB it is 2 feet so 1 psi loss.

So the Btu of the exchanger doesn't have much bearing?  The plates are what makes it happen?  I was looking at flate plate exchanger and the btu rating on a 70 plate is higher than the furnace output.  A couple of my friends have flat plate and seem to be happy. Not sure if they are quality or not?

Any answers would be greatly appreciated.

Thanks

Plumbing / Heat Exchanger

« on: August 21, 2013, 06:23:38 PM »

Hello all, I've recently purchased an OWB and have to put most of the plumbing together myself.  I was looking for some assistance in sizing the heat exchangers.  The house is 1300 square feet with an oil furnace and it is 170' from the OWB.  The pole barn is about 35 feet from the OWB and 40 x 48 with 16 foot of clear space and then open rafters.  They are both insulated.  The house has hot water baseboard and the barn will have hot water baseboard in a 300 square foot insulated office.  The rest of the barn will have a hot air blower. 

I've done all the plumbing in all of the building but am a little inexperienced in the heat exchanger realm. 

Who offers the best bang for the buck for heat exchangers?  They seem to be pretty far spaced in price when looking online.

Living in Northeast Pa.

Thanks in advance and this probably won't be my last questions.

I talked to our local DEP air quality rep today. He told me two things. Combination units that burn both coal and wood are seen as a wood only boiler and have to be phase two. Units that are over 350,000 btu are not covered by the regs due to them being considered commercial units.  He was going to check with his supervisor tomorrow and email all the information.  He said once I have that info I can purchase a unit over 350,000 and not have to be concerned with pulling it later.

Since I'm going to heat my new 40 x 48 x 16 pole barn and my house I was looking in this range anyways.


He also said they are currently having some people who broke the rules remove there OWB's " ouch".



Thanks

Thanks for the thoughts. I like simple that's why I didn't want a gasser. You know put wood in and it heats water. What are the best gassers out there?  I'm also interested in who stands behind there product the best. Any info would be great.

Thank you

General Outdoor Furnace Discussion / Pa Future OWB

« on: July 08, 2013, 10:31:56 AM »

Hello all, I'm looking into getting an OWB. I've not narrowed down the brand yet. I've looked through my great state regs about having a gasification boiler unit only. I've heard rumor of an exemption for units over 350,000 btu but can't seem to find it. Does anyone from Pa know if this exemption exists?  I would probably going over that number if it meant going with a traditional OWB.

Thanks for your help
