"For natural gas, run only the furnace for a given time, mark the dial difference on the meter and multiply the gas used by the heat multiplier for your gas supplier. This will give you a ball park estimate."
"It makes me sad to see that in the 2 years this forum has been open, there has been one post and 6 views. If we were discussing the energy value of a fart in the wind, there would be this much activity in 10 minutes! We love to discuss the insides…"
"Air sealing a wall like this must be done with a vapor diffusive material or you will get spalled stone faces from sealing materials holding water. I recommend mixing hydrated lime with local clay soils, this is the way they have been sealed for…"
"Ben, these animations are great, but they lack real information like; what kind of control system are you using, the second image in the optimal installation hits 85 % efficiency when running optimally, but what happens when the house warms and…"
I don't internet much either.
I install the bottom furring strip in pieces and usually have enough left over from the other 3 sides to piece together the bottom. This is the only time I use that funky PVC wood. I keep the holes small,…"
"After installing several of these systems, I found it difficult to maintain the low return temps necessary for condensing water from the flue gases. Latent heat is the heat that steam gives off when it changes from a higher(vapor) to a lower(liquid)…"
"Yes, a typical annual household heating bill here is about the same, but my client has spent his money on weatherization, so he is saving $600/year. There is no heating appliance that can make that kind of difference. We need to use our common sense…"
"1) Turn down the gas pressure, that is a crazy big pilot
2) Replacing this cast iron beauty is a lot more complicated than it sounds. Unless the distribution system is also updated, return water temps will be >120F resulting in your new 90%+ mod…"
"Technology has it's place, but legislating the adoption of new(or in this case not so new) technologies is not the way to reduce energy use. Last week I repaired a 100 year old NG converted coal burner for a client who has spent his money on…"
"Devices that use B-Vents should be outlawed.
When I started installing boilers and furnaces back in 1994, all I wanted to install was condensing units, but I noticed some problems with reliability and real world performance advantages. For most…"
"Terry, I have never seen it. I took apart a house with a badly leaking roof, the wing wall that was uninsulated had a 6' tall bees nest with 1000's of bees, the next bay over was dense-packed cellulose and had 0 bees."
"Some of the most knowledgeable trades people I know volunteer for Habitat for Humanity. You could help your community while gaining valuable OTJ experience and make connections with hi integrity contractors. To really "get it", you have to…"
"Hi Tom, I looked over your plans a little closer this morning and there are a couple other comments that I would like to make.
PVC is not a good choice for water pipes, since it has a low heat transfer coefficient, is prone to fracture spirally if…"
