    On the bench or on the greenhouse floor, Delta T’s radiant heating systems offer the grower distinct advantages, including accelerated rooting and plant growth, as well as 20-30% fuel savings over conventional forced air heating. Maximum soil and plant temperature control combine with the ability to create different temperature zones for the ultimate in flexible growing. And because radiant systems heat objects first and air last, people stay warmer and more comfortable, and in the cas

  • Delta-Tube - Model EPDM SD - Rubber Tube Bench Heating

    Delta-Tube - Model EPDM SD - Rubber Tube Bench Heating

    This bench system heats the greenhouse starting at the soil level. Heat rising from the bench warms the soil and the plant roots. Tubing spaced 2 to 3 inches apart provides even soil temperatures, which prove extremely beneficial to propagators. Seed germinators and plug producers have found that by heating the soil, they achieve a higher germination rate and quicker production time. Growers have found a reduction in rooting cuts by heating the soil...

  • Delta-Tub - Model EPDM LD - Rubber Tube Ground (Sand, Soil or Gravel) Heating

    Delta-Tub - Model EPDM LD - Rubber Tube Ground (Sand, Soil or Gravel) Heating

    Similar in concept to the DELTA-TUBE EPDM SD system, with the same productivity and fuel saving advantages, this hot water heating system with its 4 to 6 inch tube spacing is the system of choice for starter houses. It also excels in the nursery industry for general growing. Growers using this system for heating soil or nutrient bags of tomatoes and cucumbers have shown a 50% increase in yield. Grape growers have found a quicker and more even...

  • Delta-Tube - Model PEX - Tube Floor Heating

    Delta-Tube - Model PEX - Tube Floor Heating

    The Delta-Tube PEX heating system heats the greenhouse from the floor by running hot water through a grid of durable, cross-linked high-density polyethylene polymer tubing installed in the concrete. Using the concrete floor as a radiant surface, heat radiates from the floor into the greenhouse and directly to the plants. The direct contact between the root zone and the warm floor provides for maximum soil and plant temperature control, resulting in...

  • Greenhouse Heat Sources

    Centralized or localized? Together, that’s the first question we need to answer when it comes to heating your greenhouse. Centralized systems typically use a boiler to generate heat in one spot. Piping is then used to distribute the heat throughout the greenhouse. Centralized systems are often more efficient for large operations. However, the cost of installing and maintaining one can be high, and difficult to justify for smaller operations. These systems generally distribute heat as e

  • Delta - Heat Exchangers

    Delta - Heat Exchangers

    Our steam-to-water and water-to-water heat exchangers represent the latest technology in performance.  All are designed for superb efficiency, low maintenance, long life and fitting into tight spaces. Understanding how important growing space is, Delta T’s heat transfer units use up to 80% less floor space than shell and tube models, and weigh up to 10 times less. That means they are easy to ship and handle, and don’t use up precious...

  • Sterling - Model HS - Hot Water Unit Heaters

    Sterling - Model HS - Hot Water Unit Heaters

    Sterling model “HS” horizontal unit heaters are available in both serpentine and header designs. Serpentine units offer outputs from 8030 to 35,900 BTUs and are ideal for hot water installations with limited clearances. Header type horizontal units range from 18,000 to 360,000 BTUs, and can operate with either hot water or steam. Both units come standard with totally enclosed motors. Explosion-proof motors are also available.

  • Piping for Greenhouse Heating

    How heat is delivered in a greenhouse is critical. Even distribution of heat, without hot or cold spots, is the goal. It is a goal that Delta T takes seriously. In our experience, uneven temperatures can result in uneven crop growth rates, as well as inconsistent maturation times. That's why at Delta T, we offer a range of piping options to optimize the heating in every greenhouse. How do you know how much heat is needed for your greenhouse? Our heat loss calculator can determine how much heat

  • Centralized Greenhouse System Piping

    Centralized Greenhouse System Piping

    When a central heating system is used to produce hot water or steam, grooved steel, copper, or PVC pipes can be used to distribute the heat energy throughout the greenhouse. Hot water systems typically require more piping and circulating pumps; steam systems require fewer pipes because steam provides more BTUs per linear foot of pipe than hot water. Steam also offers less movement resistance, which means smaller pipes can be used.
