![]() ![]() As with all the other modules, changing any input automatically updates the loss figure. The Pipe Heat Loss Estimator program lets you change fluid temperature, air temperature (in the room), various pipe types and sizes, and flow rates. That’s a lot of heat to dump into a small mechanical room! I modeled my own system near boiler piping with this program and came up with a whopping 4,286 Btu/hr. ![]() Second to expansion tank sizing on my list of commonly overlooked areas is pipe heat loss. It allows you to play different delta T games, also. An orange danger window appears when you push beyond the 4-fps range. Select a fluid, temperature of the fluid and pipe type, and you’ll get pressure drop per 100 feet, velocity and a Reynolds number to boot. Just input a flow rate, temperature and fluid type.Īnother module I like a lot is the Pipe Sizer. The Hydraulic Resistance Calculator allows you to model flow and pressure drop through a device. Import this window to the first heat loss module. Again, an area volume calculator is at your disposal. Stick in windows and doors to your heart’s content, select insulation values, and chose both inside and outside wall materials. ![]() It allows you to choose the amount of earth-bermed area you also add “day-lighted” sections. The Basement Heat Loss Estimator is wonderful. I need to study this module a bit more to get the best bang for my buck. Pick a common hydronic fluid, including water, and the properties will be shown at the Fluid Properties Calculator. A great module! Very quick and easy to use. Tweak the distance above the tank, fluid types, temperatures, time of day (just kidding) - it also spits out system volume and amount of antifreeze needed at various mix percentages. With the Expansion Tank Sizer, build the system on the screen, including pipe sizes, and the tank capacity appears before your eyes! Like magic! Tank/Pipe Sizing & Heat Loss Perhaps the most often “assumed” component in hydronicizing is the expansion tank. I could fill this entire magazine with praise of this module alone! Then toggle in your choice of brands and sizes of pressure-activated bypass valves. Select a pump, switch zone valves open and close and watch the flow and pressure drops change before your eyes. Pick your “poison” regarding tube types and sizes, as well as loop lengths mix and match if you like. You just start building away, choosing from zones built with baseboard or various radiant applications from concrete slab, gypcrete and plates above or below the subfloor. ![]() If you have ever played Sims City games, you will love this, too. The Hydronic Circuit Simulator is my favorite. This is a powerful troubleshooting tool for problematic “under heat” repair calls. Each time you change your selection, the new choices will show on the diagram.Ī very nice touch, that bells and whistles sound that occurs when you get overzealous with a pump or pump speed selection and go over the 4 feet per second velocity! Also available is a range of glycol types and percentages. You can choose from a variety of baseboard and pump brands and models. The next icon on the toolbar is the Series Baseboard Simulator. It appears to have all the necessary input flexibility without going overboard. I like how the color bar graph continually updates as you enter the inputs, and it helps you spot an input mistake quickly. This module allows you to pull info from the basement calculator also, which is downstream on the tool bar. And it works! A clever area and volume calculator is a very helpful feature. Heat Load & Hydronic Circuits Working my way across the top toolbar of 10 module options, the first stop is the Room Heat Load Calculator. However, there are help screens at every module, which is a huge favor for computer-challenged folks like me. The user manual is well written and easily understood a few moments spent here will eliminate most head scratching. The entire program is colorful and well laid out - light-years ahead of the old boring DOS version. ![]()
