Unidentified electric greenhouse heater
2 Attachment(s)
Hi,
My nan has this vintage greenhouse heater that she's had for many years, and after looking, we can't find a brand, we think it might be Parwin, but are not sure, if you have any idea, please let me know, pictures below. Tom |

Hi Tom,
Yes, I think you can be pretty sure it's Parwin. I repaired one a couple of years ago for a friend, but I'm sure it had an identifying plate on it somewhere or I wouldn't have known the make. The spiders had created so much web inside over the summer that the fan blades couldn't turn! The one I did had a remote thermostat on an umbilical cord rather than a built in one. I've just typed Parwin into Google and looked at 'images'. Several pictures of your heater are shown. Hope that helps, Cheers Nick |
Re: Unidentified electric greenhouse heater
It might be a silly comment but doesn't the second picture have the name printed on the label above the switch or am I dreaming again?

It does!
Nice heater, looks rather well built! Regards Lloyd |
Re: Unidentified electric greenhouse heater
Hi all, thanks for the replies, I believe the heater is made by parwin, but would like to know several other things please, they are:
The wattage. The year. The model number It's built like a tank, it's been used for many years and has a nice vintage Eveready plug with unsleved pins on it. Tom |
Re: Unidentified electric greenhouse heater
The wattage can be found with a simple resistance check- the wirewound elements won't vary madly as they heat up. Or just plug it into one of the cheap plug in monitor boxes.

I think....that may have had a 15A round pin plug as standard. I hope it doesn't now have a 13A plug as 3kW is pushing things and could also cause the plug to deteriorate (i know it's difficult to burn down a greenhouse, and for all i know the heater might not even get used..)
If it IS still in use..If you fitted a 15A fused plug (and a socket in the appropriate place) it would hopefully have the advantage that it couldn't be used indoors! Dave |

Come to think of it, I think the heater was actually a 2.5Kw unit, th plug does not appear to have any burn marks on it. Tom |

Hi.
Slightly off topic, sorry. A friend of ours had an immersion heater fed from an MK switched 13 amp plug in her airing cupboard. She asked me to fit a 'proper' switch instead. However, I noticed that the heater was rated at FOUR kilowatts, and had been used for many years. Surpisingly, the plug showed little sign of stress, and I still have it in use in my workshop. It's like this one, but in white. |

3Kw is 13.636A at 220v, 13.04A at 230v and 12.5A at 240v, so a good quality mains plug and 13Amp fuse should be fine. The fuse will nuisance blow eventually when it gets tired but won't blow instantly unless it gets an overload.

Re: Unidentified electric greenhouse heater
And of course if the heater is rated at 240V 3kW, on a 230V supply it will only take 12A and on 220V, 11.5A approximately.
A 220V 3kW rated heater would be a problem at 240V, taking 14.9A at that voltage. (It wouldn't actually be a problem with the typical 220V mains connectors rated at 16A though.) |
