Renewable Energy Systems – Power Your Environment

Radiant Heating Systems


The energy we expend to heat our homes is one of the highest energy costs we face. In Northern climates especially, how you heat your home or business will impact your everyday life for the duration of the heating season. There are several factors which influence these costs, the main factor being the way your home is built and insulated. Following that, how you heat your home, or the type of heating system chosen is the second. Since Roman times, man has known that the best way to heat is with hot water. The delivery system has always been the problem. Thermal mass combined with efficient heat storage and transmission are the keys to an efficient and cost effective heating system.

Pex Pipe


Planetary Systems, Inc. also offers in-floor and under-floor heating products – pex pipe and fittings plus heating controls and pumps. An in-floor heating system is the most economical way to heat your home. It does require some extensive pre-planning and the up-front expenses are higher, both in labor and materials. Pex pipe used in floor systems is an extruded plastic product with an oxygen barrier to prevent corrosion of pumps and equipment. A low-oxygen glycol-water solution in your floor heating loops both prevents freezing and provides an excellent long term heating medium. Pex pipe usually has a 25 year-plus warranty, but is expected to last much longer based on recent experience.

Pex pipe used in a concrete or gypcrete flooring system will have an indefinite life cycle. We can provide pricing for these floor systems are part of your heating system.


Myth: Geothermal (ground source heat loops) are more efficient


The rules are simple. Forced air heat systems, ground source heat pumps, electric heat will always cost more and be less efficient from an overall energy use standpoint than hot water or hydronic heat. If your system is heavily dependent on electric power, and there is none, you are up the creek. Hydronic heat done badly though, can also be much less efficient. Our systems have been able to heat domestic water, provide home heat for less than any other systems on a cost basis. One example home cost only $467.00 annually in propane for a 2000+ sq.-ft. home here in Montana which included the heating system, hot water, a gas fireplace and a gas stove. Buderus is the world leader in heating systems.
