Hello , usual rule of thumb would be 50- 60 watts per sq meter but with no insulation i would advise at least double this. 5x5 meters = 25 meters square assuming the ceiling height isnt over 2.5 meters. This would mean 3000 watts. Tubular heaters are a good way to make sure you maintain a temperature. Depending on what you need to protect there might be better ways to do this such as frost heaters etc . thanks

do you know how much it is to run one of these heaters per day

Hello ,
The quick answer for a 3 foot heater on 24 hours is £0.46. If your interested the breakdown is below.
This will depend on a number of factors - which heater you buy and how much you are paying per unit of electricity. i Can give you an e.g though. To run the 3ft heater - which is 120 watts.
if you run this continuous for 24 hours , and lets say the thermostat never cut in i.e it was running the entire time (never cooled) it would use 24x 120 watts = 2880 watts. The price of electricity is approx £0.16 per unit . A unit of electricity is 1kw per hour . 2880 watts is 2.880 KW over the full 24 hours . 0.16 x 2.880 = £0.46 .
Thanks

Hello thanks for the question, the following heaters will use the following amps (approx figure using power factor 1 at 230v) -
40 watts - 0.18 amps (180 milliamps)
80 watts - 0.36 amps
120 watts - 0.52 amps
160 watts - 0.70 amps
200 watts - 0.86 amps
240 watts - 1.04 amps

Hello,
thanks for the question. How are you intending to control the temperature? heating this space should not be an issue for the 40 watt heater but this will depend on things such as the external temperature. If the external temperature was to drop very low can i assume if the resin needs to cure you are not able to make the box really air tight ? Making it air tight would make it easier to heat but this might not work for your resin. The safe option might be to install two units, you will find they will not use much more electricity as they will heat up quicker and cut out at the desired temperature. thanks

I have a small 6 foot by 4 foot greenhouse here in North Dublin and I am looking for a greenhouse heater. A colleague suggested a 'tubular' heater as they are water/damp resistant and better than traditional methods of heating a greenhouse. I am looking for one that has a thermostat and can keep a greenhouse of this size kept over 16 degrees plus during winter.
Would this product do and what size would you recommend?

A Tubular heater should do this job for you pretty nicely.
The biggest one you can fit is is what i would recommend. The reason for this is that as soon as your heater will get to the required temperature (set on the side) the sooner it will cut out

Please can you describe the differences between the Tubular Heaters by dimplex, greenbrook and eterna? Thanks

The Greenbrook and Eterna heater are only really different by aesthetics because they are the same in the way they operate - they have an internal preset stat which cuts out which it gets up to temperature. The dimplex one though has the added benefit of a controllable stat on the end of the heater - which is pretty handy. The only reason why some people dont like the dimplex heater is for e.g in a church / chapel - the stat's maybe moved by children etc.

The ECOT range of eco-heaters from Dimplex feature a discreet, smart design, in varying sizes in 1ft increments, for a huge range of applications, from airing cupboards to shop windows and greenhouses.
