Bio Green PHX 2.8 Stainless Steel Greenhouse Heater 2.8 kW (9553 BTU) — Dual Elements, Air Circulation & IPX4

The Bio Green PHX 2.8 is a compact stainless-steel electric heater and ventilator that provides adjustable heat (up to 2.8 kW/9553 BTU) and airflow control to protect plants and small structures from cold and humidity.

The PHX 2.8 from Bio Green is designed for growers and property owners who need stable temperature and better air circulation in greenhouses, garages, sheds, coops and storage rooms. Built with two independently adjustable heating elements, a stepless thermostat and an air circulation mode, this unit balances warmth and ventilation while resisting moisture with an IPX4 rating. It arrives with mounting hardware and a user-friendly control layout so you can install it on a wall, hang it or place it on the floor.

How does the PHX 2.8 maintain steady warmth without wasting energy?

The heater has two separately adjustable elements (1,000 W and 1,800 W) that can run individually or together, letting you match output to conditions. The stepless thermostat automatically cycles the elements to hold the set temperature, reducing runtime and electricity use.

• Three power settings: 1 kW, 1.8 kW, or combined 2.8 kW (9553 BTU)
• Thermostat range from -58°F to 79°F for precise control
• Automatic start/stop reduces unnecessary operation

Can it also improve air circulation and humidity control?

Yes — the PHX 2.8 includes a dedicated air circulation mode that runs the fan without heating. This prevents heat pockets, evens out temperature, and helps control local humidity around plants without continuous heating.

• Circulates up to 16,000 cubic feet of air per hour
• Quiet, smooth-running fan preserves a low-noise environment
• Air-only mode reduces condensation and heat stress

Is the heater durable and easy to install in a greenhouse or outbuilding?

The housing is made from stainless steel for physical toughness and corrosion resistance, making it suitable for damp or unheated spaces. Install options include supplied hanging chains, wall brackets or simple floor placement, so you can adapt to different structures and mounting needs.

• Stainless-steel enclosure withstands shocks and damp conditions
• Includes chains and brackets for hanging or wall mounting
• Compact footprint (approx. 18 × 15 × 11 inches) fits small spaces

What safety and electrical features should I know about?

The unit is built for 220–240V mains use and features IPX4 splash resistance for extra peace of mind in humid environments. Frost detection capabilities and the thermostat help prevent freezing conditions while limiting overheating risk through regulated operation.

• 220–240V, 60 Hz power connection suitable for regional mains
• IPX4-rated for splash resistance in damp spaces
• Frost detection and automatic thermostat control for protection

Who this unit is for: The Bio Green PHX 2.8 is aimed at hobby growers, small-scale commercial growers, and property owners who need reliable climate control in spaces up to roughly 215 sq ft with average ceiling heights. It suits anyone wanting flexible heating levels, improved air movement, and a sturdy stainless-steel build for humid or dusty environments where simple, adjustable temperature control and circulation are essential.
