Description

Product Description

The 3kw Greenhouse Heater is a dual-function device serving as either a ventilation motor or an electric heater. Its high performance can be brought to a range of indoor spaces including warehouses, workshops, greenhouses or grow rooms. This powerful heater runs quietly, it offers control through a thermostat and can heat up large spaces rapidly.

Key Features

Thermostatic control
The fan heater is reliable
The unit is durable and resistant
It's high performance and strong
It features overheating protection
Accurate temperature control

What It Does

The 3kw Greenhouse Heater pushes hot air out through its element and fan. It offers much more strength than many standard heaters. This can be used in larger grow rooms and is also able to circulate the air in such. In cooler months this is a brilliant tool to maintain temperatures. More so when the lights go out as this can help reduce or eliminate rot from your cultivation. This is a professional-grade heater more powerful than the overwhelming majority of hobbyist heaters.

How It Works

While the heater is controlled by the thermostat the fan is not. The fan motor will need manually controlling. The heating element ventilator will keep working in the event the thermostat cuts off. There are three available settings – full power, half power and fan only. The angled tube design is specifically chosen for the lack of space it takes up and its output efficiency.

Functionality

The 3kw Greenhouse Heater is dual-purpose. One function is purely for ventilation, a vital element for any grow space and this product can perform this in grow spaces of substantial size. The second and primary function of this product is for heating. This can once again be brought to warehouses as well as grow rooms and offers an array of control settings to suit the given space.

FAQs

How much electricity does a 3kW greenhouse heater use per hour?

A 3kW greenhouse heater uses 3 kilowatts of electricity per hour when running at full power. The cost depends on your electricity rate. For example, at £0.30 per kWh, it would cost around £0.90 per hour to operate. Usage may vary depending on thermostat settings and environmental factors.

What size breaker is needed for a 3kW heater?

A 3kW heater typically requires a dedicated 16-amp circuit breaker. However, it's important to check the manufacturer's specifications and consult a qualified electrician to ensure proper installation and safety, especially in a greenhouse environment.

Do greenhouse heaters use a lot of electricity?

Greenhouse heaters, like a 3kW model, can use a significant amount of electricity, especially if running continuously. However, using a thermostat, timer, and proper insulation can help manage energy consumption and reduce costs while maintaining optimal greenhouse temperatures.

Is a 3kW greenhouse heater sufficient for my greenhouse?

A 3kW greenhouse heater is suitable for heating small to medium-sized greenhouses, typically up to 15 square meters. The effectiveness depends on factors like insulation, outside temperatures, and the desired internal temperature. Always consider these factors when choosing heater size.

Can I use a 3kW heater in a greenhouse with delicate plants?

Yes, a 3kW greenhouse heater can be used with delicate plants. It often features adjustable thermostats to maintain precise temperatures. Pairing it with a fan helps distribute heat evenly, preventing hotspots and ensuring a stable environment for sensitive plants.

How do I install a 3kW greenhouse heater safely?

To install a 3kW greenhouse heater safely, ensure it is placed on a flat, stable surface away from flammable materials. Use the appropriate circuit breaker and wiring, and consider mounting it off the ground to protect it from moisture. Always follow the manufacturer’s guidelines.

How energy-efficient is a 3kW greenhouse heater?

A 3kW greenhouse heater can be energy-efficient when used with a thermostat and timer. It only operates as needed, reducing wasteful energy consumption. For maximum efficiency, ensure your greenhouse is well-insulated to retain heat and minimize the heater's workload.

Can a 3kW heater prevent frost in a greenhouse?

Yes, a 3kW greenhouse heater can effectively prevent frost, especially in well-insulated greenhouses. By maintaining a consistent temperature above freezing, it protects your plants from frost damage during cold nights and harsh winter conditions.

What is the best placement for a 3kW heater in a greenhouse?

The best placement for a 3kW greenhouse heater is typically near the center of the greenhouse or where cold air tends to enter. Ensure it's positioned to allow even heat distribution. If using a fan, place the heater where airflow can spread warmth throughout the space efficiently.
