best heating system

[_RaT_]

Your right Gary, rottable, moldable, seismicly weak walls above ground are much preferable. Of course I'm just funning you, but with the R value and the thermal mass of concrete curing in the second best know way to man, ICF is still the undisputed leader. /forums/images/graemlins/grin.gif

Tomorrow, if I have time, I will take a picture of a brand new 7200 sq ft home, 2 1/2 stories high and 100% ICF styrofoam filled cement block house.. House is going up adjacent to our property. The girl felt the high winds off th reservoir dictated all ICF.. I guess she could be right and probably would live out a tornado better than the rest of us. Although the last tornado was 40 years ago and went through downtown Worcester ( a small city).. TO sse this home is amazing..

RAT, Yes, I also got a set of plans but I plan on making many floorplan changes to the upper level. I will be down sizing the total square footage from over 4000 sqft to about 2700 sqft just to make it affordable. The guy had grand plans for this place that I will not be able to meet. Yes, we typically will use a 3 coat plaster to cover exterior walls on adobe and other surfaces and will be using that coating here as well. One other use for the ICFs that I hadn't thought about before buying this place is he used these forms for building a 6' wall enclosing an acre around the house. Considering the lengths of continous wall there are only two or three small cracks in all the wall unlike alot of concrete block walls I've seen. Seems like an expensive wall to me but his loss is my gain. Sure, I'd be interested in hearing about the lighting system you mentioned. Feel free to PM me. My wife and I are currently living in a 800sqft care takers/in laws cottage that is completed on the property. But I am starting to feel pressured to get this home completed in the next few years since we are expecting our first child this November.

We are in a similar situation. We bought a place with no house, well, a old beat up mobile home that leaks, weeps and responds to the outside temperature within mere minutes. It is 900 square feet. We have a 3 year old. I'll PM you the address of the lighting company I've used in the past. What will the interior walls be finished in? Drywall or plaster?

I don't understand the people who claim the cost of radiant slabs is too high, mine has cost 0.25$ / sq. ft for materials and that is canadian $.

I can zip tie pex to mesh as good as the next guy so we will do that ourselves. Pex has a long lifespan when not exposed to UV.

 

[_RaT_]

I've seen bare bones estimates that PEX will easily last for a minimum of 200 years. I figure that if I used it in my floor, after 200 years, I'm not really going to concern myself with its condition. Besides, by then, I'll probably switch over the the new Tritium heating system. /forums/images/graemlins/grin.gif

slowzuki,

Putting in the pipe/PEX was cheap it was the cost of generating the hot water that was expensive. Gas/Wood/Solar water heaters where just too expensive to justify.

Now if we where farther north where it gets a lot colder for a longer period of time it would be a different story. But the cost for a total radiant heating system was at least 7K for a solar solution.

Later,

"I've seen bare bones estimates that PEX will easily last for a minimum of 200 years."

That's something that I just don't believe, particularly surrounded by concrete (caustic) on one side and with hot liquid circulating on the inside. And who knows what deposits and scale will do to the stuff over time? I don't doubt that it will last longer than a lot of other materials, though.

I also estimated that it would cost about 7 grand to put in a solar heating system with a back up propane fired water heater and hot water storage tanks. Based on the solar providing 90% of my hot water needs and the current cost of propane, the system will pay for itself in approximately 5 years. Even though we are in the desert, the winter can get fairly cold, particularily at night with clear skys and living at a elevation near 5000'. Another benefit of radiant heating systems, if you are circulating water and not a glycol solution, is during the summer you can route the incoming, cool water, from your well and circulate it through your system to help cool your home. The cooling is a minimium benefit since it only cools when there is a demand for water in the home. A source that I am considering for my solar equipment is radiantsolar.com. There is a lot of information on solar heating and radiant systems if you are interested.

Rat, I haven't decided on a interior finish yet but I am leaning towards drywall since it will go up faster and leave a smoother finish, if I do it myself. I assume that you have to wire the interior walls also for the plaster to stick to the ICFs. I did notice that the plastic bracing in the ICFs do hold staples fairly well for attaching stucco wire so I assume you could just drive drywall screws in for holding up the drywall. I have been playing around a bit with the extra forms I have for putting in a dog fence/pen.

The pullout for screws in the plastic webbing is the same for pullout in wood, about 90lbs. On the interior, you would use blue rock for your plaster, no wire except lathing at corners, windows, nicho's etc. It wold be considerably more expensive then regular drywall. On the exterior, if you stucco, you attach the wire with washer head screws right into the plastic web. The advantage with the ICF is an attachment every 8" oc instead of the typical 16" oc. What are your plans for heating/cooloing?

man that sure is nice stuff huh:

anyhow yes lots of heating options, out there I think the solart would be cheapest to run yet more expensive to install, here Iu want dual fuel wood will be primary as I have 20 acres of woods with enough dead standing that I could burn for ever and more will grow before i get them all gone. infact been making some rather BIG burns just to rid myself of some last weekend made 4 or 5 burns, great weather for it, one burnt 2 days. and I loaded more on and it burnt 1 more starting on own and left only about 1/2 lb of unburnt log stump parts & rest just ash (4' high and 6 feet across pile of ash!)

I want some forms to make my car service pit in the barn! 5' high 20' long and maybe a 8' deep 12x12 room UNDER slab! would make a nice place to keep the homeland security equipment and the hot water heater & pumps.!

Steam boiler with millivolt controls and two pipe cast iron radiators.
No noise, dead silent.
No soot.
No maintenance.
No electricity required (heat during blackouts).
Convection and radiant heat fron the cast iron radiators.
The versatility of propane.
Fifty year lifecycle, minimum.
Problem, 99 percent of the heating "contractors" out there wouldn't know where to begin to design or install the system.

brad_oatley...

Sounds like a nice system...

Approximate installed cost for a new 1500 sq foot home ?

Are you from (or own) Oatley Plumbing & Heating ?

I live close by...

[brad_oatley]

Dave,
Expensive, in the 20-25,000 range. It really is a nice system. There is no nicer heat source than the old free standing cast iron radiators. Cast iron baseboard is a good alternative because the big radiators aren't architecturally appealing in all interiors.
I do own the Oatley Company. Feel free to private mail me here or call me at work. Advice is still free.

Franco belge Gravity oil feed convection heat

Click on Oil/kerosene and look for Normandie model

I cant say enough good things about these stoves...Its gravity oil feed (from main oil tank or dedicated) its pumps out 42,000 btu's of convection heat (blue flame) and on a low setting it will heat almost 1,500 sq ft with only 15 gallons of oil usuage a month....it looks like a small wood burning stove

Got one for a relative in New Hampshire - they cut the heating bill 30% probably would have been more, but it was insanely cold up there last winter....
The distributor who got me my unit heats his entire store with it all winter on a low setting -amazing

Thanks for the price shock... LOL...

...and the advice offer too ! /forums/images/graemlins/wink.gif


Maybe I should ask some plumbers to save the old cast iron radiators they replace...
