Greenhouse producers of all sizes will benefit from the high thermal efficiency of a condensing boiler while maximizing growing space. Condensing boilers increase heating efficiency by reducing energy costs and saving growing space in the process.

Niagrow can provide fire-tube boilers for various applications. A fire-tube boiler is a cylindrical high mass pressure vessel where hot flue gases pass through many small diameter tubes set within a tank of water. These hot gases transfer the heat through the walls of the tubes into the water.

• Relatively inexpensive (compared to high efficiency boilers)
• Easy to clean and maintain
• Tube replacement is straightforward

Niagrow is constantly in touch with the needs of the commercial greenhouse industry and can offer a high level of flexibility in design to match the best product to the application. The wetback “firebox” high mass boiler is ideal for greenhouse heat applications; they offer excellent combustion efficiency, compact size, simple design and reliable serviceability.

Under bench Heating Systems maintain uniform temperatures and positively affect the microclimate of plants. Air movement caused by the warmer under bench pipe reduces the humidity around the plant. Such systems are suitable for plants grown on benches, fixed tables, rolling, or transportable tables.

Perimeter Heating Systems should always be used in cold weather climates in order to protect plants growing near side and end walls. A well designed Perimeter Heating Systems provides supplemental heat along the sidewalls contributing to a uniform thermal environment throughout the greenhouse.

Overhead heating is important in areas that get seasons with cold night time temperatures. It provides the supplementary heating required to combat these cooler temperatures. While providing additional heat for these cooler months the overhead heating system can also be integrated for use with hanging basket systems and monorail and bi-rail cart set ups.

Floor heating in greenhouses has become more and more popular over the past decades because of the considerable benefits warm floors can have on greenhouse crops. In-floor heat is desired because it counteracts the heat loss that occurs from a cold concrete surface in the greenhouse; it is also non-obtrusive as it is beneath the growing surface.

• Thin wall steel tube ideally suited for heating systems in greenhouses
• Brings heat directly to the crop where it is most effective
• Lightweight and practical application
• Narrow diameter 28/35mm pipe greatly reduces volume of water needed
• Provides quick and energy efficient heating

Heating with Wood and Biomass Greenhouse Heating Solutions

Wood, as a biomass greenhouse energy source, represents a renewable form of energy with significant "untapped" potential. It's abundant, renewable, local, and an eco-friendly and economical alternative, or addition, to any modern gas, oil, or efficient greenhouse heating systems.
