What Are Grow Gadgets Tube Greenhouse Heaters?

The Grow Gadgets Tube Greenhouse Heaters are a major development in low-cost, energy efficient, heating.

Thanks to efficient performance and low running costs, these compact tube heaters are suited to prolonged heating applications. They can cost as little as half a penny per hour, depending on the power output (wattage) of the heater used (60W to 240W).

Tube Heater Applications

Tube heaters are popular for using in conservatories for inexpensive background heat and frost protection. They're simple to use and can be plugged into a conventional mains socket. These tube heaters are suitable to use with a separate thermostatic controller.

Due to their compact dimensions, tube heaters take up far less space than other types of electric heater such as, say, an oil filled radiator. They can be grouped together in specially designed brackets if more than one is to be used.

Benefits Of Using Tube Heaters For Gardeners

Plants perform best when the daytime temperature is no higher than 25°C and the night time temperature is no less than 18°C. A consistent temperature without wild fluctuations of environmental variables will always give you better results.

Temperature Variations And Humidity - Time It Right

In the cold of winter, temperatures can heavily fluctuate, especially when your lights go off, as temperature can quickly drop when the source of heat from the lamps is turned off at the onset of the night cycle.

Humidity is also linked to temperature, so when temps drop, humidity increases leading to the air reaching maximum carry capacity and the water will condense on flowers and fruit, causing issues like rot.

One of the solutions for reducing the fluctuations of temperature & humidity is to set a timer so the heater to come on around half an hour before the lights go out. This gives the heater a chance to pre-heat the room and compensate for when the warm lights go out.

Protecting your tender plants from frost with a Grow Gadgets tube heater will protect your wallet from the need to rebuy plants and from soaring costs with this energy efficient Greenhouse Tube Heater. Using around a quarter less power than other similar heater units, tube heaters come complete with wall brackets for easy mounting, and a certified 1-metre cable for use with a standard mains power supply.

They carry an IP55 rating, meaning they are suitable for use where they may come into contact with water splashes, so you can safely use them in a hydroponic environment. They're fully CE certified (BS EN 60335/1:2002 compliant). This combination of safety and energy efficiency provides you with a great choice, if you're looking for a low-cost, ambient heater to maintain steady temperatures in your grow space.
