i am looking for a used ahs 130 with domestic coil or coil canister i would also preffer belt drive. does anyone know where i can find one. i will be heating a 2200sqft bilevel in central pa with moderate insulation. the unit will be outside the home in a small building; distance is somewhat flexible. any suggestions for alternate systems would be considered.

A AHS130 used might be harder to find than say a AA130 or EFM520. All 3 would do about the same job. Any outdoor type unit is going to heat the building it is in, unless you have the insulating jackets made for that unit.

can i hook into an older aa130 for example with pex instead of copper? my dad has an older (1970's) aa130 but it is plumbed with copper tubing; the cost of the copper alone for my complete installation would probably pay for the differance from used to new. i am under the impression you can use pex for a new boiler, is their any differance in installation? (aa130 old - ahs130new)

No problem using pex with new installs. You have to tap into your boiler with either copper or iron piping.....go out at least 2' (I think)....... and then hook those pipes to the pex. Make sure you use pex al pex or HE pex so oxygen doesn't get into the system. I used pex al pex.

Personally, I would be careful of your design and how you accomplish over temperature safety. The design of the boilers hasn't changed much over the years. Piping near the boiler should be metal. Use black iron pipe for you mains comming off of the boiler, it is cheaper than copper but just takes a little more time to do a good job. You can usually get a hardware store to cut and thread the pipe for a nominal charge if you need odd lengths and don't have access to the tools.

Use the boiler you have access to, there is no difference or need to use different plumbing materials. I'd highly recommend PexAlPex, 1" for your
underground piping, but a good underground instalation with good insulation and SEALED from any moisture is very important.

I burried my PexAlPex inside two different diameter continous lengths [no seams] of corrugated drain pipe, with insulation between the different size
tubing..

If I were to do the job again, I'd also insulate the trench and put a plastic 'umbrella' over the whole trench before backfilling, just to keep rainwater
from making the ground wet/damp.. Dry dirt is an insulator, damp or wet dirt is a conductor of heat.. so keep it DRY.

Search the forum, [upper right corner of the page] for remote boiler instalations, burried pipes, PexAlPex, insulated piping, etc.. you will find answers to
all your questions.. and maybe find some ideas and techniques you hadn't thought about.

Since it sounds like you will be building a shed to locate the boiler in, I'd lean towards the AAor the EFM, since they are set up for feeding from a large coal hopper/bin. the AHS requires loading the upper gravity feed hopper every few days or each week depending on coal use rate.

If you design your boiler's building to suit the boiler, you can have a full season's worth of coal stored in the shed, then you don't have to think about adding coal, only about emptying the ash pans every few days.

my dad was telling me i could have issues if my furnace is at ground level above my basement, which i am going to be heating. something to do with the way the water circulates through the system . does anyone know anything about this? if i hook an auger to the ahs 130 will it be relatively similar to the aa130? also my uncle had a coal boiler with a hopper and had issues with coal hanging up in the hopper, does any one know any similar issues experience or heard of? also thank you all for the information thus far very helpful.

With a pressurized, pumped system there should be no issue with circulation. Open outdoor wood boilers and gravity flow systems are different.

Auger options to fill the hopper are available on the AHS.

Coal hanging up in the hopper is usually due to too many fines or too large of a coal size. Using the right size coal for the boiler is a must to be trouble free.

Take a look at other threads on this forum. There is a ton of info and will take some time to read. This should give you a better feel for what you are getting into.

most of the other things i have read seem to strongly recommend the boiler indoors. heat loss, cure damp basement, easier to maintain repair, ect. my only issue with this is i want to utilize the sqaure footage of my house best i can with a growing family and a ttl living space of 2200 sqft. how much space will i need for a utility room with just the boiler inside and bin outside? can it be next to my breaker box?

I put my boiler in my barn approximately 100 feet away from the house. It ties in to my oil boiler, which is located in the basement. Absolutely no issues as long as you select the right circulator pump. Also, I am sure there are regional variations in costs, but after crunching the numbers for the various piping alternatives for the 100 foot underground run, I went with the 1 1/4 inch thermapex sold by the local central boiler dealer. I paid about $18/ft. I looked at foam in trench ($12/ft for foam from local dealer plus pipes); insulating pipes and running through either pvc or drain pipe. Whatever option you choose, don't skimp on the underground pipe. Insulate and make sure it is watertight or you will have substantial heat loss.

Electrical codes require 36 to 42" of clearance in front of electrical equipment.

In residential settings you only need enough room to service and meet the manufacturer's required clearance to combustibles.

I would allow 3 feet of clearance around the boiler for ease of maintenance but that is not a code requirement here. It does take up some room but if you have 2200 sq ft of living space, you probably have a decent size basement and won't miss the space.
