I think that is way overkill..you are not trying to heat anywhere close to 13,000 sqft...and at 7500 watts thats like 75 -100 watt bulbs burning when it kicks on..I think this unit would kick off and on so often that it would be premature were and tear..on the unit..Bigger is not always better...B,Like this one ?

I don't know about that brand but it looks good from what I can see. Dayton from Grainger is pretty good also. Here is one a tad bit more than the one you showed. Dayton 7.5

Wait for it.
Thanks for the input BRG . Thats why I'm here asking , I dont want to pay for overkill either up front cost or monthly expense . I want something that will do the job safelly & as efficient as posible with what I have to work with . If I can find the right thing to fit my needs I'm ready to buy , If not , I have nothing but time and can continue with what I am using for now .

That is why I wanted to do a load calculation on his garage. The first unit 5kw listed as 500 square feet. Which is less than what he is trying to heat. The two units give some options and then also be capable of handling it when he wants to get up to 70. Also I am not sure of design temp as that will make a big difference.

Thanks , Grainger was the first place I looked & I am familiar with dayton from shops I have had in the past with NG overheads . I sure never had any complaints before , but never had any experience with the electric units .
I would like to keep the cost down to 5 or 600 for the initial cost though , If need be I can get 2 smaller units as you mentioned before & use as needed if need be . I'm open to any suggestions still , but I really want to stick with electric only it just fits my needs better and easier to control . I read my own electric meters dailly when I add something new because I dont like surprises a month or 2 down the road . thanks again to all .
Cowboy
Wait for it.
I,ll just wait untill you have the time to check into it before doing anything . Like I said I aint no good with numbers or figuring things out nor do I trust anyone local these days .

Qmark is a good brand also and this price is pretty good for a 5kw.
Qmark
The CFM is a tad bit less than the Dayton but should not make much difference based on what you said about how your garage holds the heat. I thought I read on the first link you posted but don't see it anymore but the 5KW was designed for 500 square feet. I based my sizing on that but now I don't see the 500 square feet anymore. I will write you back on Monday.

Thanks again , I would much rather get a brand that you think will be better then the one's I have no clue about . If it will take 2 smaller heaters to do what I want when I need the extra heat , but if one will do what I want to keep it from getting too cold at night or when I aint out there thats fine too , I can use the 2nd one as I need it .
Once again I apreciate you all sorting through my ramblings & the help you are providing . I'm perty sure its helping others then myself that might be lurking in the shadows , thats even better IMO .

according to this website you need an 8kw heater to maintain at least a 50 degree interior temp when it gets down to 0F. (and this may be able to maintain a 70 degree temp, depending on how well the shop is insulated)
OTOH, my experience dealing with commercial systems tells me that a pair of 5kw units would be a good idea - you get more capacity than you need, but the odds of both units breaking at the same time is low...

Thanks for the link Erik . Looks interesting .
While I was there I found this unit . I have been very happy with modine gas heaters in the past , granted this may be a bit small but I wanted to post it just in case . I'll await Murph's advice .

Murph , I Just went back & reread the thread & seen where you thought the Qmark was a good brand . After looking at it again & doing a little figuring I,m haveing second thoughts on the 5k modine We talked about . I can get this Qmark 7.5 K with brackets , thermostat & shipped for under 600 & the CFM rating is a bit higher as well . Any thoughts or should I spend a little more & go with the 5K Modine . Thanks again .

Just thought I would update this & thank everyone again for there input .
I had been watching an add on Craigslist for a dayton 3UG73D heater a guy had for sale , he had bought it a year ago & never took it out of the box so the warranty had expired . He finally came down on the price where I figured it was worth the risk so he delivered it thursday I got it for $250 bucks , hooked it up with a 6 foot range cord I had & replaced the end with a 50 amp plug I also had so I could plug it in in place of my welder . This is the one I got .

I knew it wasn't quite the size I wanted & the CFM output wasn't enough either , but for the money I'm perty happy so far . I just have it sitting on my welding cabinet right now but will probably hang it from the ceiling like it should be if it continues to work like it has the last few days . I'm really impressed of how much heat it puts out & is way quiter & safer then running my torpedo heater .
Now it just depends on how efficient it turns out being . But I sure wouldn't discount these types of heaters for heating a workspace or garage as long as its fairlly well insulated . I'll update when I know how efficient it is .
FYI , I have no clue why this type is blue & larger then normal I musta hit a wrong button somewhere .

The Smurf in you has come out!
Dammit I hate that when it happens
. It must of had something to do when I posted that link cuz it seems fine now.

Yep , But it never got much below 40 inside the shop overnight as long as I ran my torpedo every 24 hours or so . The coldest its been here this winter was 7 below & that spell only lasted 4 or 5 days & those temps were less the 4 hours or so .
Since I put the new heater in its staying at 50 degrees overnight with it on low & only takes 2 hours or so to bring it up to 65 degrees when I have went out to work , Still not sure on the power its using so I'm reading the meter dailly & seeing which is the best setting to keep it on .
It damn sure makes it comfy to work in , but I been doing some painting again & i need to have it warmer then normal .
Cowboy
Wait for it.
Thanks Jerry , yep its all bout the insulation & how well it is sealed up & I spent a lot of time & money on materials doing just that .
If it wasn't for the darn cold concrete floor it wouldn't take hardlly anything to heat it .
Cowboy
Wait for it.
Well I aint thought about ripping it out but since its got a 4 or 5 inch stemwall I have thought about maybe going over the top with something else like you mentioned . Sloping it to the walkin & overhead door would be the biggest problem though .Just rent a jackhammer and break it out and put some insulation and pex down before you repour it!
Might be cheaper in the long run just to do the whole damn floor in those rubber horse stall mats though , just the ones I got now sure do make a helluva difference in the area they are in . Thats one helluva lot of mats though.
If you put the mats everywhere, you may loose the heat coming up from the ground. My shop is in a remote building so it's not getting any heat from the house but it'll stay above 32 degrees when the outside temp goes down to about zero. I do have one floor almost completely covered with those mats but that area is where I found myself standing or kneeling a lot so it's worth it there.
Cowboy
Wait for it.
Thanks BC , Yep the mats I put in there sure make it nicer to walk or kneel on . If I can still get the good price on them I,ll probablly add another 10 or so but I dont think it would be worth doing the whole floor , probablly be that much harder to clean as well .
I Thought I would update this though , the heaters doing everything I need it to do which is keeping the shop between 50 & 65 as I need it . I keep a real close eye on the meter readings so I didn't have any surprises . So far it looks like adding it has cost me about an extra 60 bucks for the last month , so I am plenty happy with that .
I'll probablly turn it up a bit more this next month as I am planning on working out there quite a bit . If I can keep it under an extra 100 bucks a month I'll still be saving another 50 or 100 bucks from using the torpedo & kerosene & it sure is nice not worrying about the fumes sneaking up on me .
