Benefits and uses of electrical greenhouse heaters

By installing the right small greenhouse heating systems, you are assured of thriving plants even during the cold.

The alternative is to ignore heating or use sub-standard warming methods and of course, you won’t like the results- chances are that you will have to wave goodbye to your beloved herbs.

So, the biggest benefit of investing a heating system for your greenhouse is that you can continue growing throughout the year- with you vegetables doing well season in season out.

Where to buy electrical greenhouse heaters

You can access a variety of excellent electrical heating systems from online stores such as Amazon, eBay, Wal-Mart and others

Also, some of the manufactures have dedicated sales websites- though they only sell their own.

Still, your local gardening stores could offer more options.

  • Greenhouse heating mats

Let’s now talk about seeding:

To germinate well in winter, your plant roots need to be warmed.

One of the heating options for ​germination are the heat mats or if you like, heating pads.

Mats encourage seed germination plus the essential root formation by supplying an even base heating that works wonderfully to keep the soil warm

And once heat rises, they also supplement the heating in the rest of the plant as well.

Our team investigated a number of greenhouse heating mats and here were the findings.

  1. Factors to consider when selecting an electric greenhouse heating product

Regardless of whether it’s commercial or just a hobby, you need to identify a gadget to efficiently heat the space during the cold winter months.

Here are some considerations

  • Maintenance cost

Whatever you pick- be it a amp, a fan heater, or a heating mat; ensure it doesn’t breakdown anyhow and that it requires minimal maintenance.

Again this saves your crops, money, and time.

  • What are you growing?

The temperature needed in your greenhouse vary with the crop.

Cool-weather crops - like lettuce, cabbage, and broccoli-excel during the winter months, as they require reduced heating to thrive.

Warm-weather crops –such as tomatoes, eggplant, and peppers -are not as successful in colder climates, since your heater must work harder to maintain the right temperature for your greenhouse

If your area has varying temperatures, grow warm-weather crops during warmer months then shift to cool-weather crops in colder months.

  • How much heating will you need?

You can easily know which heater will be perfect for your greenhouse by finding the volume of heating needed to keep plants warm i.e. The BTUs (British Thermal Units) required.

You calculate the needed BTUs then pick a heater with the BTU rating to match.

  • Ease of mounting

Some heating units need special mounting hardware while others come with everything.

Pick that which can be conveniently mounted.

  • Thermostat

An electric greenhouse heater with thermostat is much easier to work with as it automatically controls heating – coming on when temperatures start sagging and going off when everything is heated well.

This reduces your involvement and saves you a lot of stress

  1. Summary

You are spoilt for choice when we come to small greenhouse heating systems - from lamps, fan heaters, and all the way to heating mats, you surely should get something convenient with your crops.

And an electric greenhouse heater with thermostat offers more convenience as heating runs almost on autopilot.
