Ventilating a Tight House

Most homeowners today are aware that insulating a new or existing home is effective at reducing home heating costs and energy waste, but with all the advantages to building “tight” there is at least one significant disadvantage – lack of fresh air.  A constant supply of fresh air is important to keeping people healthy, maintaining comfort and reducing the risk of long-term damage to building materials.  Energy efficient homes – both new and existing – require whole-house ventilation ...

Maximum home comfort with an HVAC Zoning System

Zoning is a subject that comes up time and time again this time of year because many homeowners experience uneven cooling throughout their residence. In most of these cases, a homes forced air system uses a single thermostat to control the entire homes heating and cooling needs; which can be tricky if trying to heat and cool a multistory residence or have rooms that receive different levels of use.

Many times we’ll see this in homes with finished ...

Geothermal Heat Pumps – 2013’s Green Product of the Year

Today, there are many so called “Green” products on the market but I venture to say that no “Green” product can make as large of an environmental impact as a Geothermal Heat Pump. The United States gets 84% of its total energy from oil, coal and natural gas – all of which are fossil fuels. We’ve depended on fossil fuels to provide electricity, power industries, heat our homes and operate our vehicles. As a result, the planet’s supply ...

All About Geothermal Loops

The heart of a geothermal system is the in-ground loop field (geothermal loops).  The loop field is a system of underground polyethylene pipes that are a heat source in winter and a heat sink in summer.  These pipes are heat fused at 525 degrees and are used to circulate a non-toxic and non-corrosive solution containing 75% water and 25% propylene glycol.  The thermally conductive solution is then circulated thru the pipes, where it collects earth’s thermal energy.  The collected thermal ...
