Thread: Full Boar PTC heater 1500W

Remember that a fan type heater will blow dust thru the internal filter and onto the heating element so that after a while, unless you clean it constantly, you will start to smell smoke and soon see flames. A better type of heater for what you describe would be one of those that look like a central heating radiator. These are oil filled, don't have any source of high temperature, and are easy to clean. If you get one with a fan only use the fan before you start making dust.

I've found a #7 and a gnarly piece of timber to be a good heater.

I agree with bohdan about the heater in terms of smell ad fire safety.
In addition it will mince fine dust into even finer dust particles.

Thanks for the tip about dust; one of the reasons I liked the look of the Full Boar is that it has a washable filter before the fan.

Get a heated jacket!

Took the PTC heater back, got a replacement. Same result, so not defective. Giving it a proper go now to see if the throughput of air compensates for the low outlet air temperature.

It's absolute rubbish. The air coming out is 50°C, cool enough that I can comfortably hold my hand in front of it. Not what I expected from a $155 industrial PTC heater.

I'm not sure what you expect from the heater and how you can describe the unit as "absolute rubbish"

If the temperature of domestic hot water is legislated at 50°C (max) -- so little kiddies don't scald themselves -- why would consumer safety legislation allow the sale of an item capable of producing air any hotter than the same temperature? If the little darlings will scald themselves if teh water is hotter than 50 degrees, they'll roast themselves with air hotter than the same temperature.

I think the real metric is how long the heater will take to warm the shed by recirculating the air in the shed -- after allowing for the heat escaping through openings, gaps and radiation from the walls and roof. And this will primarily be a function of the amount of air moved by the fan, not the temperature of the air coming out of the heater.

eg if your shed is 6 x 4 x 3 metres, uninsulated, and the air inside the shed is replaced every hour (according to one web site, the air within a typical older US house is replaced every 2 hours) the heater's fan would need to move something like twice the volume of your shed every hour to warm the shed from near zero. BobL probably has a better handle on the calculations -- I last did them seriously 40 years ago.

Dude, this is a generic $20 POC from Woolworths three winters ago.

The shed is uninsulated and it gets it to 18°. I know this as there is a wine fridge thermometer I use to keep a log of temps and humidity Not of the wine, the shed! (no wine left!!!)

If you zoom in, you can see a couple of marks I've made where 14 and 15 are hand written. It gets it to that in an hour and clicks on and off, even on the coldest night. I often work until 3am.

15 is OK with a jacket and socks (shoes are a luxury )

Yes, the shed will be insulated, soon. Its on the plans.....

Air and water are completely different mediums. Stay in 15 degree water and you will be extremely uncomfortably cold. Not so with air.

Same at the other extreme.

It's not marketed as a child friendly heater. Most things you buy at Bunnings are quite capable of hurting kids and they aren't expected to use them. It's very reasonable to expect children to use water taps.

Yep, got a refund, settled for the POC heater for a quarter of the $. It was either that or go up to an LPG unit but I'll survive. I don't need to warm the garage. Just want to take the edge off cold Canberra mornings so my fingers work.

well at 1500W (= 6.25A) it's not an "industrial" heater either. It would would make diddly squat difference in any factory I've ever been into.

I suspect that in this case the "industrial" is purely marketing and the unit is really just an ugly domestic room heater.
No doubt for the marketers who are quite happy to promote a vacuum cleaner as capable of drawing a continuous 40A from a 15A circuit, a 1500W "industrial" heater is a hot item. or in the OP's case not so hot.

Sure, a 1500 watt normal cheap coiled metal heater would be average but I thought PTC elements were supposed to be at least 50% hotter or something (hence the price tag because more advanced tech + electronics). Maybe just more efficient. Either way, replacement cheap ceramic fan heater is doing the trick just fine.

1500 Watts is 1500 Watts no matter how fancy and high tech the electronics are.

have just read wikipedia,
it appears that the "fancy electronics" in a PTC element are that the heating element acts as its own thermostat and thus the heater doesn't need an overload protection circuit.
