Best of all, FREE surplus solar energy can be used in your gardens to provide enormous benefits.

Radiantec systems for the home have been the environmentally-conscious choice for decades, but they're equally at home in your garden or greenhouse for a wide variety of reasons:

  • It can help jumpstart and extend your growing season by eliminating frost early and keeping ideal growing conditions long after most gardeners have packed it in.
  • Root zone heating stimulates healthier, bigger plants and is more important to plant growth than leaf temperature.
  • Soil micro-organisms show maximum growth and activity at optimum soil temperatures above 45° F, which has a profound influence on seed germination, root and shoot growth, and nutrient uptake and crop growth.
  • Faster composting results from higher consistent temperatures, allowing you to utilize compost sooner.
  • Getting an early start and planting in warmer soil results in better, earlier yields from fruit and vegetables.
  • Greenhouse growers can achieve substantial energy savings by lowering air temperatures as much as 15° F during cold weather.

At RADIANTEC, we support the use of excess solar thermal energy for gardening purposes because it supports the ethic of generating high quality food locally from small patches, and even urban patches, free of pesticides, unnatural fertilizers, and exorbitant transportation and energy cost.

Root zone heating: getting to the bottom of healthier plants.

Root zone heating, whether in the garden or greenhouse, is proven to stimulate better bacterial and root action resulting in healthier, bigger and more productive plants. There are copious amounts of research on this topic, not to mention books available. The correct temperature range is especially vital at first planting and in the first weeks and months following. For gardeners who start their plants in a greenhouse and transplant early in the season, ensuring an optimum soil temperature helps plants take well to the new environment. In the same vein, watering your garden with very cold water - especially early in the season - can set your plants back. With a solar domestic water heater as part of your Radiantec heating system you will often have more hot water than you need for the household. On those days, you can water the garden with warm water that has no extra cost either to you or the environment.

Better, faster, more - composting with radiant heat.

Heating your compost pile or bin with low-grade heat from your system that is not needed for other purposes (i.e., low temperature or waste heat) will generate high quality compost faster than you thought possible, instead of waiting many weeks or months. Radiant heating lines run under the compost can be part of your garden system or on a separate line - Radiantec systems give you the ultimate in flexibility depending on your needs.
