Hose A client came into my store a few weeks back to discuss his idea for an inexpensive “batch” water heater that doesn’t require any high tech parts or pumps. The idea behind a batch heater in general is to pre-heat water from the well or from the town source with the sun or a [...] Solar Heating If you have the opportunity to replace your heating system or if you are building a new house, you should consider a low temperature water-based system for the heating core. For instance, a radiant floor system or hydro-air system are both based on heating water to temperatures much lower than those required for [...] Solar Collector The solar collector we are building at my future house, 78 Main St, has been in place for a couple of weeks now, and we have been collecting temperature data. I’m hoping to have some “live” data at the website at some point in the future, but for now I have downloaded 8 [...] Google PI Today is March 14th, for some that’s 3.14 (pi, π) day. Pi is the greek symbol representing the constant which is the ratio of the circumference of a circle to its diameter. Google often takes the opportunity to acknowledge an interesting day (or date) on its front page, and they did so today [...]
bonfire I think back to my pre-Enfield days (almost a year ago) and I used to say “Keep the home fires burning” just for fun…I’d smile to myself and imagine sitting in front of a fireplace with my feet up on the coffee table. That’s not my vision any more. I moved into a rental house [...]
Solar Storage tank Unfortunately we had a problem with the webcam and didn’t get any time-lapse pictures of the second day of building the solar storage tank (see Thermal storage tank, part 1 from the first day). We did get some video footage and a few stills, see below. The first day was the [...]
Solar heat For our zero-energy building we are using the sun to provide ALL of the heat we will need throughout the winter. After months of discussion, engineering models of heat requirements, heat losses, heat storage and solar heat generation… the team came up with a system. There are three major ingredients: Solar collector BTUs from the Sun At the end of last week we had a good meeting with Murphy’s Cell-Tech, our energy consultant, who has done the thermal modeling for our house to determine the number of BTUs entering and leaving. The people involved in the model included experts in insulation, thermal seal of the building, [...] Over the last few weeks I have had the opportunity to speak with people in detail about their energy usage. Specifically, by looking at the latest electric bill we have been able to get some insight into equipment or processes that are using much more electricity than expected. Here are three examples: 1 – I visited [...] Wood pile If you have been thinking about replacing your current heating system or just trying to understand your current system better, you may want to compare it to alternative systems. Let’s say you currently have a oil-burning furnace that supplies forced hot water through baseboard heaters. You have paid about 600 gallons of oil [...] |
