Some Basic Greenhouse Tips

A good greenhouse heater can make all the difference to your plants during winter to protect them from frost and ice. And the good news is is that you can pick up a decent heater for your greenhouse relatively cheaply.


Now dependent on your needs, 'cheap' can still  be expensive and you can safely expect to spend less or more depending on the size of your greenhouse. Take a Bosmere 2000 Watt Electric greenhouse Heater - if you shop around you can pick one up for less than £30 which isn't too bad for a greenhouse of smaller proportions. Though, for a larger and more powerful heater, such as a Bio Green Phoenix, you could be looking close to £200. As you can see, you need to be pretty sure of what you need before dipping your hand in your pocket, otherwise you can end up spending more than what you really need to.  


The insulation on most plastic greenhouse have quite a low insulation value and so the purchase of the correct greenhouse heater is important to replace any lost heat. The use of either an electrical heating system, or paraffin heater, are in my opinion the best choice when looking to replace any heat loss. It’s a good idea to try and find a greenhouse heater with a thermostat as part of the package as accurately controlling the temperature in your greenhouse is just as important as replacing the lost heat.  


If I stick my neck on the line, I'd advise against a propane gas heater - certainly if you're just starting up - as you can pay quite a packet bit for a good model. Though, that's just a personal opinion on my part and I certainly won't rule out a gas heater on the basis that it wasn't up for the job (and gas heaters have potentially the cheapest running costs).  


The running costs of your greenhouse heater are an important consideration. The current price per unit of electricity in the UK is about 15p (average) which will see the cost of your running a 1000w greenhouse heater to be rougly that amount per hour. A paraffin heater, though, could cost about double that for the same time. Double? Well, yeas, but you need to be aware that a paraffin greenhouse heater keeps pushing out heat after it's turned off and will do until the oil inside finally cools down. Make sure to take this into consideration if you're ever building your own greenhouse.


My own personal preference is an electrical greenhouse heater as I like the "cheaper now" option as I don't have a huge budget and with the inbuilt thermostats on most products these days, I can keep the temperature within my own greenhouse just right, but don't let that put you off a paraffin or gas heater if your need or budget stretches that far - each option does an brilliant job of keeping the temperature of your greenhouse just right.
