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 [...] Solar Collector We are finally making progress again on the solar heating system at 78 Main St. After building the tank (Solar Storage), building the collector rack and trench to the basement, and building the heat exchanger (see pictures below), the next step was to get the two main loops pumping (see Solar Storage Tank, [...] Solar Thermal Storage It took a while to get this going but we finally have a time-lapsed video of the building of the solar storage tank. This tank was designed by TSS (Thermal Storage Solutions) with installation help from Murphy Cell-Tech and Greenworks Solar. I set up a webcam to get the time-lapsed photography [...]
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 [...]
Shower Time There is a lot of buzz these days about On-Demand hot water systems. “On-Demand” means the water is heated as it is needed. Most people have a hot water tank, where the water is heated and kept hot in a tank until it is needed. Generally the tank has been sized to provide [...]
Simple Solar Hot Water The store has been open just about 4 weeks and we are about to install the first solar hot water system sold through the store! At the high level view of the system, there is a closed loop of pipes containing water/glycol that transfer heat from the solar collector on the [...] 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 [...] |
