Radiant heat vs blue flame

How to Choose the Right Wall-Mount Heater

If you are looking for indevelopment around wall-mount heaters, I will assume that it is either winter and you desire to heat up, or you are preparing for winter and desire to continue to be heat. If among these cases is true, then you are in the ideal location.

You watching: Radiant heat vs blue flame

Below, I cover the difference between plaque heaters and also blue flame heaters, and I display you just how to figure out just how many kind of British thermal devices (BTUs) you will certainly have to warm your area.

Propane or Natural Gas?

In all actuality, this question is not as essential as it as soon as was. Many type of contemporary units can be used through either propane or natural gas.

And to clarify a little more, once I say propane I am talking about liquid propane or LP. This would mean hooking the heater up to a propane tank—great for portable situations. And organic gas would certainly have actually a difficult hook up and would be a more permanent situation.

It's crucial to look at the cost of fuel for both methods and also the expense of connecting to the heater. Some people execute not desire a tank sitting in one of their rooms and this makes organic gas a much better choice for them. Some world will just desire the heater out during winter and might take it other areas with them, so the propane choice might be much better for them.

What Is "Blue Flame"?

People contact convection warmth "blue flame" ssuggest because there is primarily a blue-colored flame at the bottom of the wall-mount heater.

Convection Heaters

Convection heaters are an extra typical develop of heating. Convection warmth actually warms the air initially. And you could ask, "What does that matter?" Well, if the air is heated initially, it rises. If you have actually an old home through high ceilings, then this may not be the ideal warm resource for you because the warm air will collect up at the ceiling. And if the old house has actually drafts, the air will certainly be cooled also quicker. Convection warm will certainly not be the a lot of reliable choice for a grand also old home.


Radiant Heater


Infrared Radiant Plaque Heaters

New modern technology appears to lug in longer names, at least it appears that means to me fifty percent the moment. The plaque heater is more recent innovation. It has actually a screening that emits heat. Infrared radiant plaque heaters warm the humidity and also solids in a room first. You feel the floors and furniture warming up and also by heating the moisture in the room it has actually much less motion.

If we go ago to the old home, this is the heater that is going to be more efficient. By heating the moisture, it moves upwards slower and the objects faster. So the heat is remaining even more at the level of the heater fairly than a draft pushing it around. And for a home that is new and airtight, this heater would certainly not be as good as a convection heater.

Easy BTU Calculation

If you have actually eight foot ceilings a basic means to figure out just how many kind of BTUs you require is 30 BTUs per square foot. Or if you have better ceilings than 3.75 BTUs per cubic foot. Many newer residences have actually eight-foot ceilings though and this is an less complicated method to figure out BTUs.


As proclaimed previously, BTU implies British thermal unit. The BTU is rather interesting, it is actually a unit of energy that equals 1,055 joules. A little bit more meaning is that a BTU is the approximate amount of power it takes to warm one pound of water from 39 to 40 degrees Fahrenheit. When you are looking approximately at heating and cooling appliances and view a ssuggest "BTU: 25,000" or whatever before number, it is actually definition BTU per hour. Now remember what I simply told you—because it is pretty a lot usemuch less and you will never before should know it.

What you will certainly need to understand to figure out how many type of BTUs you will certainly require it the cubic feet you will be trying to warm. One BTU is adequate to warmth around 55 cubic feet by one level Fahrenheit. So take the length and multiply it by the width. Then multiply this number by the elevation of the room. And you have your cubic feet. Now take that total cubic feet and divide it by 55. Keep the answer for later—we will certainly speak to this number X.

Now take the lowest temperature you are expecting outside, and also be realistic about this, and then number out what temperature you would certainly choose to have actually it inside your house. Take the difference in between the 2 by subtracting the low temperature from the wanted temperature. Keep this number—we will certainly call it Y.

Now take X and also multiply it by Y. And the equation you have need to carry back some memories: X * Y = X. And X in this situation is the BTU's you will have to provide you through the temperature you desire.

Wall Mount Heaters

The all at once message below is that there are different instances for different wall heaters. The technologies actually execute warmth things in different ways and also this is an important thing to understand to gain the best usage out of the appliance that you usage.

And expertise exactly how to number out the essential BTU per hour rating that will certainly work for you. Once you understand the ssuggest equations to figuring this out it will not be hard to buy what you require. And after reading this write-up I hope that I have actually armed you via the indevelopment you should discover what will certainly be ideal for you. Good luck and remain warm!

Questions & Answers

Question: Between blue flame or plaque heaters, which would certainly you recommend for a basement 2 auto garage 30’x40’?

Answer: For a basement that size, If I was going to be making use of a wall mount, I don't think I would certainly usage one.

Question: We have an old residence that is blocked and also has 7-foot ceilings. Which form of heater would be best?

Answer: I would certainly recommfinish a convection heater a.k.a. plaque heater. Since it heats the moisture in the air and also object, the warmth doesn't settle as high and through drafts it doesn't relocate as much.

Question: Which puts off much less moisture; blue flame or red flame?

Answer: I am assuming you suppose blue flame as in convection heat and also red flame as in radiant warmth. Blue flame is a widespread name for convection and also plaque heater is prevalent for radiant heat. It isn't that either of them give off moisture, but convection warm warms the actual air and radiant heats the moisture in the air.

Question: Does one kind of heater heat quicker than the other? For instance an enclosed snowmobile trailer when morning temps are single digits?

Answer: For these forms of heaters, tbelow is little distinction. The blue flame would heat a little faster however also disperse more easily through a draft.

Question: I have a vent complimentary 20,000 BTU heater and want to recognize if I can usage a regulator and also hose off a gas grille to run my heater?

Answer: You would certainly need to look at the psi for the vent complimentary heater, however it need to be okay to perform this given that both speak to for a low-push regulator.

Question: I desire to warm two rooms via a wall-mounted propane heater. We have actually a hardwood stove in the kitchen and also have actually an electrical space heater in the adjoining bedroom. Both rooms measure about 2.303 cubic feet. Could I put my wall heater on the wall behind the wood oven or by the door of the bedroom?

Answer: I would certainly look for better placement, and recalculate your area.

Question: Can you use wall heaters in little locations choose steed trailers?

Answer: You could, although I would just carry out so via some caution.

Question: I'm utilizing a blue flame gas wall heater in a 17x17 room that is on a cement slab. I've mounted vinyl plank flooring. I use the heater in the spring and also autumn. After the room starts to heat up the floor gets extremely wet from condensation. Will using a gas plaque heater take care of the moisture obtaining on the floor?

Answer: Tbelow would certainly still be some problem from the condensation. I carry out not imagine tbelow would be a noticeable difference. If you maintained it running and also at an even temperature that would help.

Question: What's the best heater for a bathroom?

Answer: Completely matters on your warmth source. Electric, propane, organic gas, etc..

Question: I have a ceramic studio on an exposed concrete slab via single pane home windows and also 2x4 construction. Leaking, to say the least. It's north Ca. So our coldest is about 24 degrees and also that's not very frequently. The room is 15 x 17 via a peaked ceiling so I averaging it at 11'. I come up through needing about 30000 btu's. Would a plaque heater fueled by propane be able to warmth a room of these dimensions? My heater that simply passed away is a large old cabinet beast that heated the ceiling better than the floor.

Answer: I would certainly go via somepoint slightly bigger, mostly because concrete will proceed to absorb the warmth for a while and I don't know what insulation you have actually on the wall surfaces.

Question: Which propane heater puts off more Carbon monoxide? The radiant heate or blue flame?

Answer: I don't know especially, the factor they are vent-totally free solutions is because they are designed to burn off the carbon monoxide and also be safe for indoor usage.

Question: I am planning on running a heater once I am functioning in my garage, which one is better?

Answer: I would recommfinish the plaque heater, although both will certainly take time to warm a space up.

Question: We have actually plastic in our patio. What heater would be best?

Answer: I would certainly recommend finding a space heater, plastic will certainly not be a high quality insulator and also you would lose the warm extremely quickly.

Question: Vinyl plank flooring gets wet via a gas heater on a concrete slab. Would plaque heating be better?

Answer: This would need to execute via sudden alters in temperature, if you had the unit set for a details temperature that have to help.

I have a sunroom 300 sq. feet and also it’s insulated, must I get a 10,000 blue flame or 2-plaque organic gas...

Chris Andrews (author) from Norwalk, Ohio on October 18, 2017:

David, I appreciate all feedback. Tbelow are many aspect affiliated to be more precise, and also I don't think the large majority of civilization are going to have actually access to this. I have the right to talk around insulation components, day of construct, form of structure material, local wind components, and the list can go on. Many human being don't have the knowledge for the in depth detail and also research study that a lot of of this would take so most retailers carry out discover a method to meacertain for the average instead of the margins. I do appreciate that you raised awareness tright here was any confusion.

Gil on September 27, 2017:

Thank you all for the indevelopment, im trying also number out the cost of running the unit. Just to make sure I appropriately understand the instruction. I have actually a room dimension 10' x 10' x 8' = 800 cubic feet split by 55 = 14.54 number X. Desire temperature 70 degrees - lowers expected temperature 25 degrees = 45 number Y. X14.54 x Y45 = X654.3 Btu's per hour needed. 1 gallon of propane will certainly yield 90,000 Btu's split by 654.3 = 137.55 hrs of heat. 137.55 separated by 24 hour in a day = 5.7 days of warm from 1 gallon. Im pain $2.60 a gallon, 31 days separated by 5.7 = 5.4 gallons x $2.60 = $14.14 a month total expense to run the unit, according to the formula above. Ill be making use of a 10,000 but init Dynamics's Glo blue flame. Is this correct

David Brick on September 26, 2017:

Chris, I enjoyed your short article comparing blue flame through infrared vent-complimentary heaters. It was exceptionally indevelopmental as far as that comparichild goes. Since some civilization might still be analysis your write-up, though, I feel compelled to let them understand that your method for sizing the capacity of a heater is woefully poor. In order to appropriately dimension a heating system for a building, you should know at what price the building will lose heat to the surrounding setting under the most adverse conditions normally intended for the location in which it is situated. The heater should create at least that amount of warm in order to compensate for those losses and preserve a consistent temperature inside.

The losses are a non-trivial combination of conduction, convection and also radiation. The as a whole calculation has actually been greatly simplified by the American Society of Heating Refrigeration and also Air Conditioning Engineers, however still makes use of a number of factors, including building building form, insulation, infiltration, ventilation, and so on, which your equation does not. In other words, ASHRAE simplified; you have oversimplified.

By multiplying the inner volume of a residence by the number 55, you are attempting to apply an extremely coarse type of thumbpreeminence that could occupational under a very specific set of circumstances, yet would certainly be entirely inexact for others. As "Bob" found, for instance, your equation grossly underapproximated his need for heating capacity.

Bob on January 17, 2017:

My calculations (utilizing your formula) for my 8' x 16' x 8' enclosed insulated porch for a delta-T of 50F levels reflects a requirement of under 1000 BTU/hr. My trial via 3000 watts electrical heat (10,000 BTU/hr) failed miserably. Other input such as yours repeatedly shows a require of practically 20,000 BTU/hr for the very same problems. Perhaps you're off by a couple of thousand percent!

CJ Andrews on October 03, 2016:

Brenda I am glad that you sought more indevelopment. Last year was a negative year for them as well. Tright here was a dual fuel via many models that finished up required a converter to work properly. This year it appears most models are either LP or Propane.

Judy my bees are telling me it is going to be a lengthy loss, but my gut tells me it will be a harsh winter as soon as it does hit us.

Judy on September 28, 2016:

Thank you, you are the initially one that gave me the correct way to number for BTU's. Now I will certainly look for the correct heater.

Brenda on September 23, 2016:

Thank you. I backed out of buying last night when i realized i didn't have enough information. This simply made my day.

Chris Andrews (author) from Norwalk, Ohio on November 02, 2012:

The asterisk in the equation means multiply.

Charlotte on November 02, 2012:

Is the * in the equation a plus or multiply or subtract?

Chris Andrews (author) from Norwalk, Ohio on August 04, 2011:

Thanks Steve! I appreciate your comment - specifically given that you are a pretty handy perboy.

StBriggs from Ohio on August 04, 2011:

Very indevelopmental. I know this is a topic I gain many questions about and also you did an excellent task explaining the BTU's needed.
