How To Do A Forced-air To Solar Conversion

<p style&equals;"text-align&colon; justify&semi;">Forced-air to solar energy is one of the most popular conversions&comma; not because it&&num;8217&semi;s the best&comma; but because so many homes already have a forced-air solar energy system&period; It&&num;8217&semi;s much less efficient and less comfortable than radiant heating&period; It grew up as <span style&equals;"text-decoration&colon; underline&semi;">the<&sol;span> result of a compromise&period; Burning fossil fuel requires a flue to carry out exhaust gases&comma; and larger furnaces are more efficient&period; So instead of each room having a small heater with its own chimney&comma; one big furnace was used&period; As people decided they wanted all the rooms in their homes heated&comma; a way of ducting heated air through the house was devised&period; Moving air feels cooler than static air&comma; so we keep our homes warmer to feel comfortable&period; This uses more fuel&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;"><img class&equals;"aligncenter size-full wp-image-1029" src&equals;"http&colon;&sol;&sol;incrediblemag&period;com&sol;wp-content&sol;uploads&sol;2015&sol;02&sol;unnamed&period;png" alt&equals;"How To Do A Forced-air To Solar Conversion" width&equals;"580" height&equals;"436" &sol;><&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">When your solar energy heating system is an air-type&comma; the valving is different&period; A system which collects and uses solar heat directly can be valved into an existing commercial solar energy system&period;  These are general design sketches&comma; modify as required to fit your needs&period; Probably the smoothest way to do it is to have the hot air supply from the storage bin feed into the original cold-air return line&period; It can be cut in anywhere between the existing cold-air intake and the main circulating fan&period; A one-way&comma; flapper valve is needed so that air will be prevented from going backward through the storage bin or solar energy collectors when the system is in fossil fuel operation&period; The flapper door can be set closed&comma; open or partially open&comma; either manually or electrically so that you can take air from the collectors&comma; the house&&num;8217&semi;s cold-air intake register&comma; or both&comma; as needed&period; It&&num;8217&semi;s also possible to draw air only from storage&comma; or directly from the collectors as needed&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">Air to an air-type commercial solar energy collecting system may be drawn out of the house anywhere convenient and routed to the collector&period; It doesn&&num;8217&semi;t have to come out via the existing cold-air return line although that is often the more convenient&period; Generally you should have a separate to 3&sol;4 Hp fan pull air from the dwelling and push it through the collector&lpar;s&rpar; or the storage vessel&period; Pushing air through collectors creates a turbulent &&num;8220&semi;scrubbing&&num;8221&semi; effect to absorb more heat&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">The primary factor in control is attitude&period; If you don’t take charge of your system&comma; it will be beyond control in a short time&period; During assembly eliminate all sources of trouble before they happen&period; No aspect of assembly of a component or a total system is good enough&comma; if you want control&period; If you’re taking advantage of the higher efficiency of the Heat&sol;Vap concept&comma; and using a parabolic energy collecting device&comma; it’s critical&period; All of your components must be physically and mathematically checked for precise coordination&period;<&sol;p>&NewLine;
