@ March 25, 2012 6:11 PM in Revising heatloss calc with addition of unvented atticthe economy went in the toilet, I repaired, set up and installed standing seam machines and gutter machines.The "old school" metal roofs would last 80 or 90 years without leaking. They had none of the modern coatings applied to them.They are not the "tin roofs" of old, and now are being installed on mansions.We had a few contractors that did nothing but copper roofs.

- Metal roofs have coatings that prevent 75 to 80 percent of the sun's energy from being absorbed into the roof.A metal roof can reduce roof surface temperatures by 60 to 70 degrees.
@ March 25, 2012 12:37 PM in Sensor/Thermostat problem?But it's the reason you're there.Imagine if they left the home unattended, and there was a cold snap. They might walk back into a disaster area, with pipes burst and flooding. Best Wishes
@ March 25, 2012 12:13 PM in Sensor/Thermostat problem?The heat will not go on in the evenings when it's 45* degrees or so outside, call the homeowner. It may be an issue they are familiar with. They may want you to try changing a battery in the thermostat.If language is a barrier, they may call the tech themselves and explain what you have encountered.Take a close look at the thermostat, if it takes a battery, many have a "low battery" indicator on the display.
@ March 24, 2012 3:05 PM in Revising heatloss calc with addition of unvented atticI misread your post. I thought you were planning on adding registers in the ceiling to heat the space. Two pound urethane foam is what I would use.
@ March 24, 2012 2:36 PM in Where to start?the mains should be between the risers and the equalizer.Everything leaving the boiler in the same direction. With that configuration you're pushing very wet steam.
@ March 24, 2012 2:18 PM in Revising heatloss calc with addition of unvented atticyou'll redo the heat loss for all the rooms below the attic, change the ceiling heights( you plan to vent through), and add necessary emitters?
@ March 24, 2012 2:03 PM in copper fill and vent in mass.new homeowners.....something that the home inspection probably won't catch.The vent for the tank should be as large or larger than the fill pipe.This helps prevent the tank from bursting when being filled. The oil man is standing there, waiting for the whistle to stop, so he knows the tank is full. How many gallons will he pump into your basement before he realizes something's wrong?
@ March 24, 2012 1:44 PM in Revising heatloss calc with addition of unvented atticthought it was just me........Why go through all that work, when simply properly insulating what you have now, accomplishes the same thing. If you were reclaiming usable space, it would make sense.
@ March 22, 2012 7:42 PM in What's the BEST solution for this...Just like air, hot water will rise above cold.

@ March 22, 2012 7:24 AM in Boiler Efficiencyseries 8, 3 section w/ carlin ez-gas now offered by the manufacturer.
@ March 20, 2012 6:44 PM in indirectyourself a favor....don't tell the kids it's a reduced flow. It's like telling a kid that a food is "good for them".They won't like it.
@ March 20, 2012 2:05 PM in OKThe gas company is going to put the next size larger meter in. Smith now offers the series 8 with a Carlin EZ-Gas, so that ought to make things easier. I think you're gonna see a lot of manufacturers following suit.
