Garage heater---questions


Recommended Posts

I am in the process of building a new house and I am thinking about installing a LP garage heater. But I am not sure what are the better brands and what size I would need. The garage will be around 25'x35' with 10' ceiling. The garage will be fulling insulated and drywalled. With my research I am looking at a Lennox LF24-75a heater with is 75,000 btu's. Does this sound right?

 

SO if you have some info or advise please help me out.

 

Also if you have a heater share what you have and what size garage you are heating.

have you thought about going with radiant floor heat? when i build my garage in the spring i most likely will be going with that.

 

 

I thought about it but I just want to get a lp heater. I want one that is ceiling mounting so I can put it in the corner of the garage.

I have a coal stove to heat my garage, keep it at 55 degrees when not using it and it seems like the perfect temp for the winter...Works great and dowsn't cost much to run, lots of coal in my area and I am able to haul it myself. Doesn't take up much room and is simple to maintain.

The only disadvantage is having an open flame while doing certain jobs. Just have to be careful with how much flammable stuff you are spraying..............Something to think about with gas as well.

Why are you going with LP? Is natural gas not available?

 

 

Sorry Not LP it will be Natural Gas heater. Wasn't thinking when typing. I am in the process of designing the house so I have a rough idea of what I need so they can run the correct gas line into the garage to supply the heater. I might not get a heater right away but want it all ready so I can do it later down the road. My garage will be fully insulated and drywalled. I went to a couple model homes from my builder and the garages that are insulated are about 50 degrees inside when the outside temp was 0 degrees. SO I can live with that for a while until I install a heater.

^^^^^^^^^^^^^^^^^^^

My garage is fully finished (including the attic) and stays around 50 degrees without heat UNTIL one of the doors are opened. Opening on of the doors basically removes a wall and it gets cold.

 

Just a suggestion : Keep the thermostat about 10ft-15ft from your heat source. That way it doesn't get to hot in there. I had my thermostat next to the man door at first but it got way to hot by the time it registered 55 degrees in the winter (felt like 70). Moved it over by the coheat source and it stays comfortable at 55degrees.

Radiant in the floor with a small effecient boiler feeding it would be the best.. If not I would do a 2-stage 95% effecient gas furnace with the up flow cased coil this way if you decide to do a/c the coil and ductwork are there.. I just put heat in my buddys garage came out great.. You can either stand the furnace in the corner and run the duct up and across the ceiling, Or hang it in the attic space of the garage with the duct up there insulated..Also regardless were the furnace and ductwork goes install the vents low in the wall..' heat rises' so thats the best place for them and a big central return, Bigger isnt always better but in this case you want to make sure you have enough and slightly over so the equipment isnt runnin and running trying to keep up.. I would go with a 80-90,000 btu.. Being that the furnace is a 2-stage its only going to produce what it needs.. So If its 65 degrees in there and you want 68-70 the furnace will come on in 1st stage at say 45,000 btus, until satisfied.. If its 30 in there and you set it for 70 it will come on 1st stage and when it realizes it needs more it will go into 2nd. Send me a msg if you need anything, Also go with goodman not lenox..Ive been using goodman for 7-8 yrs and its the best equipment for the money.. If you have to have a brand name the go with carrier.lenox,etc.. But goodman is the best IMO

I work in custom homes here in the Toronto area, Lots of houses use radiant floor heat in the kitchen,bathroom, and garages. Some even do their driveways!!!

This system would be super because you can adjust the zones very easily that you want to be heated with no dust,combustion problems,and a real constant heat through out the areas heated.

 

Gas mounted heater in the garages are ok , but not for working with combustables, get dirty quicker ,some are noisy.

Just my opinion.... I assume you want the garage to be like a man cave when it is finished.

The garage will not be a man cave. It will be my work shop/garage.

 

I am going to stick with the gas mounted unit. I just want something so when I go in the garage to change the oil or rotate tires, that I can just turn on and heat up the area some. Not looking to have it 60-70 degrees all the time. Just warm enough to do some maintance on the cars and wash them during the winter.

I was going to suggest AC for your garage but you say it is going to be for basic use. Is this garage going to be attached to your house or detached? My attached garage stays a steady 50 degrees all Winter with no heater at all but it is surrounded by two sides of living space and my kitchen is above it, plus it is well insulated.

It is attached and will have R13 or R15 wall and R42 ceiling insulation and fully drywalled. It will have 10' ceilings. Also during the winter my garage doors are not open very long so the heat should stay in.

 

I have been in a couple model homes and the garage is about 50 degrees when it is in single digits outside.

 

What my plan is now is get the gas and electric plumbed and wired to where the heater will be and put the heater in later down the road.
