Quartz vs Ceramic heaters?

Bout to purchase two heaters to,offset our propane consumption. Can't decide which is best, quartz or ceramic. Would appreciate your recommendations. Which are quieter, most efficient, etc.

Well to start with, all electric heaters are nearly 100% efficient, no heat is lost up a chimney or vent.

As for quiet, the fan is the culprit, not the source of heat. The most commonly available silent safe heater is the oil-filled radiator style. But their also the largest physically.

Past that, see if a store will let you plug in a few demo models and see what you think of them.

I like the Lasko pedestal heaters Pedestal Heaters – Ceramic Portable Heaters – Space Saving Ceramic Heaters | Lasko Products, Inc.. The fan is barely audible, and the oscillation distributes the heat nicely.

You probably get what you pay for when it comes to noise levels? I understand the newer style Dyson fans are quite quiet but are also quite expensive. They call them blade less but you just can't see it

+1 on the Lasko Ceramic Heaters. I've had one in my rig for about 3 months now. Warms the entire interior. Great backup if you run out of propane or just want to heat differently once in awhile.

Murf2u had it almost right when when he said that all electric heaters are nearly 100% efficient, they are exactly 100% efficient, HERE is why I say this. ALL losses are expressed as heat, if heat is the desired product, all losses become heat so you get full recovery. And before anyone yammers about the fan,, Well the movement of air causes friction, which generates heat.. Or the light given off by some, It too becomes heat when it strikes a absorbent surface. So it's all heat.

Quartz heaters are usually large, and expensive and work exactly as well as a 20 dollar ceramic. Their one advantage is that they are harder to tip over by accident.

So get the smaller ceramic (Cause in RV's you need smaller) and make sure it has a tip over switch.

I had asked that same question several years ago...and got a decent answer. Ceramic is more efficient according to this information. I chose ceramic based on help from this site.
Comparison of Quartz Vs Ceramic Heaters for space heating

In addition... I was pointed towards the Pelonis HC-461 and i bought one for my rig. It has a few nice features...SIZE, cleanable filter (I have pets that travel) and if it gets bumped over it shuts off.

Anyone who claims this type of electric heater is more efficient than that type is a liar, ALL electric heaters are exactly 100% efficient, they can be nothing else.

I keep saying the same thing and usually no one listen.
Its all a way to make more money. And some end up believing that a 110V heater is more effective then tried an true 220volt system.

I am a fan of the oil filled radiator heaters, dead quiet and nice heat.

If you consider nothing but the conversion efficiency you're correct. If you consider how we occupy a space and how we're warmed by them different types will be more efficient because they will require different run times to keep us comfortable.

This website is misleading. They are only claiming the ceramic is more efficient because a 1.3KW ceramic unit is used instead of a 3KW quart unit. They would have you believe the two units are doing the same job of heating the people equally, but don't back up that claim with any scientific measurements or facts. You and I are not seated at that cold outdoor table having dinner to judge, but I can tell you the 3KW quartz heater is putting out lots more heat. If my head is hot, then they mounted it too close to the table :-)

The website is also discussing only the radiant type of ceramic and quartz heaters, i.e. NO FAN. So the commonly available quartz and ceramic heaters at the big box stores are not even in this category. If they have a fan, then they are convection heaters not radiant. They have a fan because they are heating air not people.

I have no problems with your choice of the Pelonis HC-461 as a quality made heater. I would probably buy it too ! However my choice would only be made evaluating units for quality, features, and safety. They will all put out the same amount of heat for the same wattage. Quartz or ceramic makes no difference if there is a fan pushing air through the unit, the differences in the wavelength of light emitted also have no measurable effect....again it's the fan moving air which is heated by the hot object (ceramic elements or quartz tubes).

We have used both Quartz and Ceramic. Much prefer the Quartz for heat. Does not seem to take moisture out of the heated air. The Eden Pure type heaters do take up more room. But they do not heat up items like the Ceramic heaters do. This is important when heating up a area like a RV. Where items can get close to the heater.
