Another Window Question

We all know windows are cold in winter and do a poor job of keeping the heat in.  Unfortunately, the calculations that show the potential savings for new windows are dismal, with an extremely long…Continue

Bud Poll replied to TJ Alexander's discussion So many homes have poorly installed fiberglass insulation. Have you been successful with a retrofit dense pack cellulose?
"Hi TJ, I've never recommended it due to the cost benefit of adding the dense pack.  Even a poorly installed assembly will benefit from whatever insulation is there limiting the improvement that can be credited to drilling, dense packing,…"

Bud Poll replied to Dan Wise's discussion Convert BTU/hr in a Manual J to actual fuel usages
"Hi eric, Before we can reverse engineer that peak heat loss number from the manual J (MJ) report we need to know what they included when calculating it.  MJ is noted for over-estimating the appliance size, so has the 51,000 btus/hr number…"

Bud Poll replied to Dan Wise's discussion Convert BTU/hr in a Manual J to actual fuel usages
"If 51,000 is your actual heat loss at the design temperature then you need a system capacity of 51,000 BTUs running continuously to maintain the set temperature.  A 60,000 BTU boiler running at 95% efficiency would just barely keep up. …"

Bud Poll replied to Dan Wise's discussion Convert BTU/hr in a Manual J to actual fuel usages
"Hi Dan, That would be close to correct if every day was at the design temperature.  I don't use Manual J, so tell me what you have for the design temperature heat loss per hour and then the total heat loss per year at your local HDD. Bud"
