We want to install earth tubes and any other energy saving options. I was reading your blog and wondering how those jujitsu mini heaters work. Do they replace conventional FAU's? <br />Can I install Brian's ERV in line with the earth tubes? Any other article you'd recommend to read about house energy efficiency? <br />Please forward my contact info to Brian as well.<br />Thank you,<br />Mike <br />profhomedev@sbcglobal.net<br />Anonymoushttps://www.blogger.com/profile/17331849271670027422noreply@blogger.comtag:blogger.com,1999:blog-6637950872592121488.post-51363021904239269262014-01-21T13:12:28.270-05:002014-01-21T13:12:28.270-05:00G,

Unit can be programmed to operate at specific times of the day only, reducing power consumption even further. We found using our PEX home run system is not the greatest setup for such a unit, in practice. While hot water delivery times were reduced, we feel we would need more remote valves to assist in further time reductions. Given that we use a ground well and our hot water usage is relatively small (for the two of us), we felt its usage wasn't a priority.First Passive House in Pennsylvaniahttps://www.blogger.com/profile/04743919388043479340noreply@blogger.comtag:blogger.com,1999:blog-6637950872592121488.post-57020874016881898612013-11-29T05:59:12.731-05:002013-11-29T05:59:12.731-05:00This comment has been removed by a blog administrator.Anonymoushttps://www.blogger.com/profile/02422784742525074974noreply@blogger.comtag:blogger.com,1999:blog-6637950872592121488.post-79212737126595149852013-11-27T23:54:42.364-05:002013-11-27T23:54:42.364-05:00This comment has been removed by a blog administrator.Heating Ontariohttps://www.blogger.com/profile/12617220641335631547noreply@blogger.comtag:blogger.com,1999:blog-6637950872592121488.post-23009941640985185192013-11-25T20:39:01.426-05:002013-11-25T20:39:01.426-05:00I'm an neophyte in this area but I asked someo...I'm an neophyte in this area but I asked someone at our local utility and he said these pumps are one of the worst energy wasters you can have in your house.

Wonderful land and I love your rustic interior wood look!<br /><br />Have you determined your heating and cooling loads yet? Depending upon your requirements that could suggest the sizing of the system.<br /><br />We had to overcome some real challenges and truthfully the EAT was installed later than it should have been, requiring us to re-dig around our foundation. We also have to be concerned with Radon levels in our area, and while we are fairing well on this front, it should be something that is considered before undertaking its construction.<br /><br />My choice with installing them was in part due to my desire to add to the general knowledge of EAT utilization in Passivhaus construction. Something that we have really little data on. Jason Morosko (http://www.sustainablepath.us/) and I both wanted to contribute so we both made the plunge.<br /><br />I would certainly consider installing them, but it is essential to design a system that won't present failures in the future.<br /><br />You should hook up with Larry at http://www.earthairtubes.com/. He is out your way, which should make it very convenient for you.<br /><br />Congratulations on your efforts!<br /><br />BobFirst Passive House in Pennsylvaniahttps://www.blogger.com/profile/04743919388043479340noreply@blogger.comtag:blogger.com,1999:blog-6637950872592121488.post-17838615969832464942013-08-06T11:10:58.654-04:002013-08-06T11:10:58.654-04:00Hi Bob, I am glad I stumbled upon your website.

I have been reading all your post because I am planning on building a passive solar designed pole constructed home in Iowa that we plant to start building in April of 2015. I will be doing a lot of the same things you have done, like having most of my windows facing true south with over hangs to take advantage of the lower winter sun for heating our concrete floors. The home will have 6" walls and a white roof, and have radiant floor heating. I am trying to decided what form of cooling we will use and that is how I found your blog.<br />Now that you have used your Earth tubes and your Mini's to help cool your house, do you still thing they are worth the cost of installation?

Yes the water takes a bit longer to come to the taps, but since it is only my wife and I and it only really comes into play when we shower (for the first one), we're not sure that it makes a lot of sense for us. That coupled with the fact that home runs, we have found are the least efficient configuration for such a system. We may need to add additional endpoints to other taps to derive the most benefit from it. So for now it is off, as we continue to monitor our energy consumption and seek to minimize it wherever we can.First Passive House in Pennsylvaniahttps://www.blogger.com/profile/04743919388043479340noreply@blogger.comtag:blogger.com,1999:blog-6637950872592121488.post-64098912128935481602013-07-29T18:45:15.618-04:002013-07-29T18:45:15.618-04:00Good choice.

How much load did you measure? If it's 4kWh/day for 2 units that must be 83W standby for each unit - is it really that bad?
