Heating Systems:

The transference of energy from point a (heat source) to point b (needed delivery place).  There are 4 different ways of doing so.
1. Is with moving of tempered air through large ductwork.
2. Moving of a liquid through pipes to a energy defuser of said energy
3. Radiant heat; like a heating element heating an oven or a fireplace heating a room or the sun through a window heating up the room in the wintertime.

* Forced air: This is the cheapest way to install a heating system with the poorest way of heating the objects in the house. With some manual and electrical parts running the system.  When the furnace fan turns on it blows cold air for a couple of minutes until the ductwork gets warm. Then it delivers the needed warm air for warming the ambient air in the room. Once the room temperature is reached, the air passively warms the items in the room. Starting with the ceiling and upper walls of the room working its way down to the floor.
* When it comes to cooling the forced air system works the best. I takes a powerful fan to drive the cold heavy air to the top floor allowing it to cascade downward cooling the item’s it come in contact with. This means the floor will be the first large surface to be cooled than slowly it works it’s way up to the level of the thermostat. You will still have a lot of hot and humid air at the ceiling if the heating contract did not install a high wall return air duct.
*  It’s also the best and I think the only way to really clean the air, removing air born allergens out of the air. You can use secondary air filtration units but the biggest one I’ve seen only does 1 room at a time trapping a person with allergies in 1 room or in 1 area of a house. Using a high quality air filter on your furnace (they can be Paper) about 5” thick do a great job of cleaning all the air for the entire house.

* Hot water heat: Is a good way to heat a house. With a boiler you convert fuel into hot water. With this type of system you can do multi-tasking of different types of jobs at the same time.
* Such as using radiators to heat the air, in-floor heat to heat floor surfaces such as front & back entry floors to melt the snow and evaporate the water or heat the bathroom floor and even heat the sidewalls of your shower to make your shower a better experience for you.
* With in-floor heat you can heat the basement floor that is the hardest surface to heat, while using hot air blows above the floor it will never actually heat the concrete floor. But having the pipe in the floor, the floor becomes a large radiator heating the room, making the enjoyable, instead of saying well we have a basement. Whats so nice about in-floor heat you have no moving air or cold drafts moving across the floor.
* The next area to heat with the hot water is the garage floor your car will love it the snow and ice melt off of it quickly taking with it the salt. Using a forced air blower in a garage is nice but the floor all ways stay cold and if you in your garage a lot you differ projects on till the warmer months of the year.
* And finally you can heat your driveway and sidewalks, think about you newer have to lift a shovel again.

* Steam Heat: Steam heat is the most efficient way it has the greatest exchange of energy. The only draw back is you must have a licensed steam boiler operator in house 24/7.

A new law is on the books starting in July of 2009

All new houses in Minnesota are required to have radon removal system installed into each housing unit. Various designs are allowed by the state some with collection tanks (sump baskets) and some with out. The state haves mandated the following items that must be done.
Install a perpetrated drain pipe around the interior foundation wall with a minimum 4 inches of course fill not sand allowing water and radon gas to migrate to the collection center.
Install a continuous 6-mill poly vapor barrier under the entire concrete floor
Seal all penetrations coming through the concrete floor pipes block wall to floor edges etc…
Seal the collection tank only leaving 2 sealed pipes coming out 1 for removal of underground water; the 2nd is for the removal of radon gas.
Install a 3” vent pipe vertically from the collection area passing through the house and venting above the roofline.

State's layout

Let’s look at the actual working of installation of said law, install a 6-mill poly on the dirt before you lay out rebar or wire mess. The steel being inserted onto the concrete keeps 1 the concrete floor from cracking, separating, shifting, or shrinking 2. It reinforces the floor incase the dirt under the floor settles. Rebar comes 1/2” x 20 feet long and is heave and flops around like a fish out of water. You will have a number of holes in the poly liner before the rebar is laid out and tied together.  If you use wire mesh this comes in rolls of 5 foot wide x 20 inches diameter about 100 foot per roll, when you unroll this little monster it acts like a slinky wanting to recoil the only way to straighten it out is to flip it over and re-bending it by hand. Resolutes at each end of 1 row you have just punchered the poly membrane 10-12 time.
The code says you must take a new piece of poly and over lap the hole by 1’ on all sides no a basement of 22 x 38 (24’ x 40’ House) a minimum of 120 holes. Now its time to pour the concrete (concrete is a mix of sand small rock, portland and water) you can install it 2 ways; wheel barrow it to the location and dump it, or you can pump it in with a large pump truck add $800.00 to the bill. Did you fix all the holes the wheelbarrow made and the guys pouring the floor, well that’s a radon leak.
After the floor has harden up you walk around the floor sealing all joints between the floor and wall and floor and any protrusions through the floor. About 1 –2 years after the house is done because you chose not to install reinforcing in the floor your floor have at least 3 and up to 10 large cracks big enough to put a tooth pick in it. Oh that’s right you laid carpet on the floor you’ll never see the cracks where the radon is getting in the living space and where Johnny and Amber likes to play and sleep on the floor.

Let’s look at the collection and exhaust system. Remember in this collection area there is standing water as well as an electric pump to pump out the ground water. Facts undisputed radon gas is heavier than air. So radon gas builds up in the collection tank it never leaves the tank and the vent pipe because it’s to heavy now the ground water comes into the collection tank what happens to the radon gas it rises and falls according to water level in the collection tank.  In fact the radon gas in the tank will increase in the parts per million making it more toxic I feel bad for the plumber that must change out the sump pump, he has to get down in there to fix the problem.  Note when the radon gas moves up into the exhaust vent, it’s now looking for an easier way out, that crack in the floor has a lot less pressure and a bigger area to expand into.   Solve the problem (the states view point) Just add a fan and blow the radon gas out of the house. The problem is it does matter how small or big the fan is if there is no air coming in to the drainage system you will never blow any air up the pipe, let alone radon gas which is heavier than air. The state say’s all you need is a small fan, may be rounding about 10 minutes per hour. 1st the state don’t have a clue how much air in cubic feet of air per minute or per hour is going to ventilate the radon gas from below the floor to solve the problem.

Let’s say it’s possible to vent this gas out of the house, well you don’t want to see the pipe from the front side of the house, let’s vent it on the back side of the roof, great or is it. On the backside of the house are the following screened, porch, deck, sand box, swing set, and other toys to play with. Radon gas is heavier than air it’s pumped on to your roof and taken away with prevailing winds and if there is no wind it rolls of the roof and into your backyard.  Looking down at your house from the sky we see the following a pipe sticking out of the roof with no cover over it and you can not cover it by law, that means when it rains water goes down the pipe so what it goes into a sump tank if water can go down so can cold air in the winter time, when this happens it will freeze the surface water in the sump tank or the ground in the collection area and if there fan is installed water will be dripping and getting the fan soaking wet. Well we no longer can use a cheap fan we must put in a stainless steel fan with a concealed shaft with a water bypass system in it. ”$” Now to make this system work we must bring in air into the drainage system. We cannot take inside air just for the fact if the power went out the radon gas has an easy way back into the house. We can us outside air it 20 below or greater in the wintertime freezing the sub soil under your floor and leaving the opportunity to heave your footing.
The only air available to you is in the new law that no one has thought about, you must have an exhaust fan run 15-20 minutes per hour. Blow this air under you floor and the radon fan pumps the radon gas filled air out of your house.  Now you are running 2 electric fans and praying the power never goes out.

Radon Shield

Or Just excavate and other 24” lower and install an angled concrete slab 4” with rebar cover with epoxy paint than build on top of it for your house the radon gas will come in contact with the lower slab and slide upward to the surface level on what ever side you choose to bring it to the surface

Dewalt DW718 12″ double bevel sliding compound miter saw

Items to look for in a miter box.
1. Is the backrest high enough to do crown molding as lest 3 1/2″?
2. Does the turntable move freely or can the dust and cut offs get under the
backrest and the turntable?

3. Can you lock the turntable at 1/10 of a degree at a time?

4. Does the miter box allow you to set the blade depth as to kurf a board
or notch the backside of a baseboard?

5. Are you able to set the turntable as 69 degrees both ways, all the miter
boxes I know of can not do this yet. When you are doing beam ceiling
with 45degree boxes the miter angle is 67 1/2 degrees this angle is used
a lot on a 6 ply beam build up?

6. Can the bevel turn to 50 degrees both directions?

7. Does the slide arm have a second dairy lock for custom cutting?

To date I have used several different types and brands of miter boxes not one is perfect but the Dewalt Series of miter boxes are a delight to work with.

Chlorine Bleach does not kill mold

Chlorine Bleach (sodium hypochlorite 6%) does not kill mold. Why?

Mold’s roots (root structures) actually grow into wood and drywall like roots.

The roots are not killed by bleach because bleach’s ion structure prevents chlorine from penetrating into porous materials such as dry wall and wood. Continue reading
