@ July 27, 2014 1:17 PM in upside down furnaceWhy aren't downflow furnaces more common?
@ July 27, 2014 1:09 PM in Another Steam Boiler Sizing ConcernEven if power burner burns less gas than atmospheric; what about the electricity the power burner needs?
@ July 26, 2014 3:43 PM in Cleaning 1-1/2" tub drain lineOld ferrous sharp bend traps rust closed. No tool I've seen will open the up leg from the down leg.
This is something I wonder about.Why do bath and shower traps often have such sharp turn?
@ July 23, 2014 8:36 PM in What did it cost in 1960?Late seventies I remember CI still costing less than copper fin. I also believe that builders paid $1000.00 to install boiler,piping,and radiators in three storey units,store on ground and two apartments above. These are hazy memories but what sticks in my mind is paying a few hundred$ each for small Hydrotherm boilers. That would be late seventies.
@ July 22, 2014 5:23 PM in Electric Baseboard Vs Hydronic Electric BaseboardsIcesailor can stand in front of and behind one of those dish type radiant heaters and then decide if it's in his head. Comfort depends on combination of air temperature and radiant temperature.
@ July 21, 2014 2:03 PM in Constantly purging air in hydronic systemEventually bladder fails. People with foresight then replace with old fashioned gas water tank. At least that tank will never need replacing. Some people with even more foresight pressurize with nitrogen.
@ July 21, 2014 1:53 PM in Electric Baseboard Vs Hydronic Electric BaseboardsLiquid filled is much more satisfactory than plain heating elements.The latter cools off too quickly after thermostat switches it off. I also second Mark's suggestion to consider ceiling radiant. Most people are more comfortable at lower air temperature.
@ July 20, 2014 1:48 PM in Constantly purging air in hydronic systemWorks better and longer if it is high enough, & if pressure is controlled. For example,some antique open tank systems are trouble free for generations. Air always gets into every hydronic system and water always disappears. Trouble free venting requires a device at a high enough location with low enough pressure so that water doesn't touch the device. In buildings with elevators automatic vents are installed in the penthouse.There they operate for decades until somebody or something(stupid PRV) blows the thing right off.
@ July 19, 2014 3:25 PM in radiator cover box design questionApartment building. Steel siding was added to east wall. Rooms against this wall went from too cold to too hot. Installed louvered enclosures. Tenants could adjust louvres instead of complain. I believe heating was one pipe.
I like the idea of adding thermal mass but I would not use the radiator for support.
@ July 15, 2014 3:45 PM in boiler or forced air - need adviceI figure cooling load in Port Arthur is a third of heating load there. Also cold air is less viscous than hot air. Another advantage of AC only is that registers don't have to be near outside walls. If beaverpilot can work in attic he can put the air handler and ducts there.
@ July 14, 2014 5:36 PM in boiler or forced air - need adviceAC only in Port Arthur can be smaller than for heating. If boiler uses natural gas and works,what's the hurry to replace?
@ July 8, 2014 5:36 PM in Trap on 4" sewer main in basementLong ago Toronto had unvented building traps outside. Somebody thought that sewer rats wouldn't swim through them.
@ July 8, 2014 5:25 PM in Low flow air solar wallsSaw many installations in Canada on industrial buildings in nineteen seventies. Difference between comfy and chilly is only a few degrees.
@ July 8, 2014 5:12 PM in Jury Rules That CSST is a Defective ProductWhy not lightning rods?
@ July 8, 2014 5:05 PM in Peer review please...Maybe you don't need no stinking solar collector? Ever notice how snow disappears under a maple tree? So...... maybe you just have to insert pipes or rods thirty feet down to draw geothermal heat up to driveway. I never heard of it but I'm interested in how well that would work and also what objections envirowhackos will fabricate.
@ June 12, 2014 5:53 PM in Steam-Heated Hotel!Lodges there were steam heated there generations ago. One pipe. Hydro Quebec pushed electric. Most went baseboard instead of radiant.
@ June 4, 2014 4:27 PM in Water TowersIn addition to what SWEI says,it depends on water & sewerage rates. Are there any districts that waive sewer fees for evaporated water? Avid gardeners should put a meter on their hose bib and try to get money back as well.
@ June 3, 2014 5:12 PM in Solar Thermal is DeadDragline, how large are your solar collectors? How much money do you figure you're saving with your solar thermal collectors?
@ June 3, 2014 4:56 PM in Water TowersClosed circuit cooler is much better than open cooling tower over the long run. Sometimes a dry cooler makes the most economic sense.
@ June 3, 2014 4:45 PM in Gravity systemsOutside boiler house is good idea. Locate it lower than bottom of house. Fire should be controlled. Ideally wood is burnt in two stages. First stage is incomplete combustion. It is simpler to buy coal and supplement with some free wood.
