Energy Efficiency

Fifth Home Slide Fuel conservation is essential with today’s high energy costs. With the addition of a Hydronic solar heating system integrated into the space heating system Legrand Construction’s homes provide the comfort of infloor heating and drastically reduced energy bills.

Each solar system is custom designed by one of the foremost solar heating engineers in the country, utilizing advanced Tekmar controls, a high efficiency on demand boiler and high efficiency Hydronic solar panels.

Active Solar Heating System

                                                   Active Solar System in Durango



The above schematic shows the integration of solar collectors into a boiler heated Hydronic system.  Heated water from the solar collectors is maintained in an insulated storage tank of 5oo gal to 1500 gal size depending on how large a system is desired.  This is approximately 500k to 1.5M BTUs of energy.  With this much heating capacity the boiler becomes secondary to the solar system and the majority of space heating done by the solar panels.  System efficiency is maintained by sensors that continually feed information to the controller.
