Figure 5: Original (left) and improved (right) pressure relief valve location.
The new thermoelectric condensing chamber is 1.125 x 8.125 x 3.25 inches (0.02858 x 0.2064 x
0.08255 m). As before, the top of the chamber is made of copper onto which the thermoelectric
generators will be attached. The pipe from the boiler attaches to the bottom as well as the pressure
relief valve (150 psi). For added safety, an additional pressure relief valve (with a cracking pressure of
175 psi) will also be attached to the bottom.
The 150 psi pressure relief valve is enclosed by another tank with three exits. These three exits
connect to the copper condensing tubes. 3/8 inch tank flanges allow copper fittings to be directly
attached to the pressure relief valve enclosure and to the holding tank. The top two flanges each
connect to copper “T” fittings that allow two condensing tubes to be connected to each. The bottom
flange prevents any liquid water from collecting in the pressure relief valve enclosure by connecting to
another condensing tube that will go directly to the holding tank. All five condensing tubes connect to a
single 3/8 inch tank flange in the top of the holding tank.
