@ July 11, 2014 4:29 PM in Jury Rules That CSST is a Defective Productwe covered the object....we covered the manufacturer... can we put just a little blame, maybe...on the person who squeezes the trigger. LOL

@ July 9, 2014 11:38 PM in Looking to make condensate neutralizerwith the plug up and fill it with calcite. Calcite is crushed limestone used to fill water neutralizers available where you purchase water treatment equipment.
@ July 5, 2014 11:16 PM in stupidityfiberglass or rock wool around so it can cake up inside your sweaty pores is a whole new dimension i'm missing out on. But far be it from me to deny some young apprentice with a beeper his initiation rights. LOL
@ July 5, 2014 11:36 AM in stupiditysince I am the only employee of this company we dont allow any attic jobs when its hot or make the recommendation of removing the ridiculous system and install ductless. LOL
@ June 28, 2014 8:40 PM in Freon leakand jealous neighbors releasing it, it makes sense to just top it off and install a set of locking caps to give yourself a baseline. Then follow it from there. I will spend a little time looking for the obvious but today there are to many variables.
@ June 28, 2014 8:25 PM in Whole house de-humidifierductless hp with internal solenoids allows indoor coil to be partially used as condenser effectively allowing for dehumidification without temperature change. very quiet.
I have also been using the White Rodgers stat with dehumidification control. This is just a relay in the stat that is unenergized until humidity level is reached and then energized. All my ecm units have the de terminal ready to go but if using on an older system a rib relay can be easily used to change motor speeds to slow airspeed over the coil until humidity level reached. I find bringing airflow back to 75% really gives a (properly sized unit) time to clean out the humidity.
@ May 19, 2014 9:36 PM in Dryer vent questionI recently was ask to repair a dryer vent in a large home. Unfortunately the dryer is set in a centrally located room 35 feet from the outside wall. Right now the dryer vent goes up to a lint box on the wall behind it and then drops down into the finished basement where it runs over 30 feet tucked up against the bottom of the joist, then it jumps up between the last joist and the outside wall for a couple of feet and terminates through a dryer outlet.
It is installed with 2 ft sections of aluminum duct and taped together, the connector and termination are spiral wound vent pipe taped to the hard pipe.
Of course this thing leaks and you can follow the tape as it gets thicker and thicker at every leak.
Any suggestion? I was thinking sch 40 pvc with a drip leg but code wont allow.
@ March 15, 2014 9:34 AM in Mod/Con Heat Exchanger DesignsAluminum...cheap and easy..aluminum casting was 8th grade metal shop.
Giannoni and others.....bend and stamp. Remember o rings in Giannoni,finally after many failures welded the tubes.
Triangle....robotic welding..by far and away the most expensive and complexed way to build an exchanger but you are no longer limited.
@ March 2, 2014 5:58 PM in New Home, Which heat source????https://www.youtube.com/watch?v=cPIjuNFPeKM
Also although you can use a tank type water heater with the altherma. Its hard to beat a tankless that never runs out of hot water. When it comes to the comfort of domestic hot water then go with comfort first and economy second.
@ March 2, 2014 11:18 AM in New Home, Which heat source????and PV panels. This is the only way you will gain complete energy independence. New microinverter panels allow you to plug and play panels as you can afford them.
Wood pellets still keep you at the mercy of pellet makers and they use energy to make them. If all of a sudden China decides to pay double for wood pellets guess what happens to you. Also while your building install a centralized chimney for a wood stove.
@ March 1, 2014 11:02 AM in Heating-Cooling Loss and GainHow many of you live in areas where a heat loss is required for a permit and how is that implemented? I would like to have it in our area but need a few ideas how to bring it before the board?
@ February 25, 2014 8:50 AM in The best Delta T for a mod-con?Thats one of the reasons our curves are not linear. We have to move them to compensate for these variables. Look what happens to convection after you get to 120.
The point is..the btu loss of the house is predetermined...The average temp across the existing radiation is also predetermined by the loss of the house.. Therefore the output of the boiler is also predetermined.... so if we are adding x amount of btus to raise the temp of x amount of # of water the whole thing will see equilibrium in very short order.
Piping it this way or that way means nothing( from a btu and temperature standpoint) of course some boilers have to be piped differently because of pressure drop issues.

@ February 24, 2014 8:03 PM in Coil Material Opinions:Put in some new inverter mini splits. R8 for air temp of 55 and attic temp of 120 thats a 65 degree delta t. They require more in a wall thats a 20 degree delta t.
I did it in my place and it cut my bill in more than half.
@ February 24, 2014 11:23 AM in The best Delta T for a mod-con?Lets just say we have a one room house with one radiator. We do a heat load on the home and on a 30 degree day it needs 10000 btus to maintain what is being lost.
We look at our radiator, we measure it, we open the book and it says that piece of radiation will need an average water temp of 170 degrees to emit 10000 btus an hour. We look at our outside temp and it is 30 degrees...perfect. Ok so we figure if we put in 180 to the rad and we adjust the flow that we get 160 out...20 degree delta t, 170 average, we are emitting 10000 btus and are going to replace just what is being lost..that day and time.
We do have options, we could put in 175 degree water and adjust the flow that we have 165 coming out..again we have our 170 degree radiator, not too much not too little.
or we could put in 190 degree water and adjust flow that we get 150 out...average temp...170 and again were right on the money... you can do what you want, as long as your average temp of the radiator is 170, anything else is too much or too little for that day. It doesnt matter what you do back at the boiler, pri sec, straight through, whatever.
In a very short time the system will reach equilibrium and the boiler will modulate down to exactly what is being consumed...10000 btus.

@ February 22, 2014 10:10 AM in geothermal vs. airsourceThere is no magic to them, the press likes to talk them up but they are just a heat pump with a water cooled condenser and in your case it just thinks its 50 degrees out all year round. Just a plain old Copland compressor and a couple of heat exchangers.
@ February 22, 2014 10:04 AM in geothermal vs. airsourceThe actual amount of water going through the Geo is 4-1/2 gpm. With fresh water you only need 1-1/2 gpm per ton. Close loops are double that. I was just saying that my well could easily feed the geo unit and all the house usage. No need to dig another well.
Cupronickel is offered by all manufacturers as an option, cheap insurance as well water can change over time.
I also filter the water with one of those centrifugal sediment removers, they work well and are very easy to blow out even when the units running.
The pipe going to my stream is only a couple of inches underground but pitches continuously toward the stream so it drains down when finished. Never had any trouble even with sub 0 weather.
I dont cool with mine...chilled water is a pain to insulate and pipe. Ductless mini inverters are to good to waste your time and money on chilled water. So you wont need a desuperheater option, they only work in ac mode. If you want to make domestic hot water you can pipe it like a boiler with an indirect water tank.
