What Size Rinnai Direct Vent Heater Do I Need

Heater sizing and type

I wanted to go some advice on the size and type of LP heater to install in my garage. I'm looking for a heater to maintain the temperature in the garage in the 45-50 degree range in the winter, but exist able to plow it upward to 55 or lx degrees when I want to work out at that place. Vented or ventless? I was thinking 45000 BTU input for a vented heater or 30000 BTU input for a non-vented heater. Whatever thoughts on size? The garage is 24' x 30' deep, two wooden garage doors, block/brick walls, fiberboard ceiling (8') with fiberglass insulation in the attic (4"-6"). Traditional truss roof. One wall abutts the house, no other sources of estrus. Western PA climate. Whatsoever advice would be appreciated. The coldest it has gotten in the garage is about 25 degrees when the outside temp was 5 beneath nix.

come up on u guys....

I can't believe u guys recommened that crap, hot dawg unit. Yep, its cheap and I've taken them out. Why as all sorched air unit, the heat STAYED upward at the ceiling and customers complained nearly cold feet on concrete floor.... I employ the direct vented wall, sealed combustion, wall heater unit of measurement. Have fan on peak, sucked in the air into unit and blow the heated air across the cold flooring earlier rising to ceiling.. Aye, more than work, costs more than simply customers Love it !

Bias noted!

I represent Rinnai, just I tin can tell you that while putting new floor pans in this old car I've been working on, information technology has been sweet, sugariness, sweetness while on the creeper under the machine having the air coming off the DV Energysaver blowing across the floor in my garage. When it is 0deg. outside I can get upwards on a Sat morning, go down and turn the heat on and within 30 min I'grand working in my shirtsleeves. You want a direct vent for a garage equally yous accept to many flammables. As well, anything which outgases and is airborne goes thru the heater and if information technology smelled bad going in, it volition odour worse coming out. Safety start, vented, sealed combustion.

hey, rinnai guy

I've been hearing adds for rinnai "ductless heaters" for common cold rooms. I thought they were talking electrical heaters until the add mentions *something* ignition??? at present i think they are calling it a 'ventless' heater without using the give-and-take "ventless".

whats the scoup?

Ductless is just that no ducts, in most the room air comes in the tiptop and blows out the lesser, v are direct vent units and 2 are ventfree, the ii vent gratuitous come up with optional fans

The HotDawgs are smashing if you lot but want to continue the car warm, but if you want comfort I concord the Rinnai are nicer with the oestrus blowing out down depression, modulating flame should be better for gas comsumption, and quieter when you lot need to call back.

Rinnai is advertisement

Both the vented and unvented heaters, mostly in the NE every bit it is the largest market. I would refer you to world wide web.rinnai.the states and world wide web.ductlessheating.com.

While I sell a lot of vent free heaters, I am a vented heater guy by grooming and inclination. Vent frees are for supplemental rut and I use my straight vent units as primary rut. Rinnai vent frees are superior to anything in the market with their modulating gas valves and blowers and they brand them in sizes that are appropriate (smallest is the model 229 which will fire from 2000-6000 btu)to the space they should be asked to heat.

Rinnai'southward are a solution type product for a contractor or homeowner. I know I will not supplant a contractors furnaces or boilers but everyone here has one or two or five or 10 jobs a year where these are the perfect solution. They are easy to install, high efficiency, cool to the touch on, fix back t-stat (on 431 & 556WTA models) and they take bang-up venting flexibility.

For a contractor they represent a peachy profit heart. Again, easy/fast to install, highly reliable and the customers love them and sell others for the contractor.

When you look at the energy environment today, the consumer is over the barrel. They need aid and in many cases practice not know whre to turn. Oft, information technology does not make sense to put in an all new heating organization. The numbers just don't work. The add-on of a Rinnai Energysaver volition afford "seasonal" efficiencies. What I mean by that is it makes no sense to fire the 100kbtu boiler to deliver a teacup worth of heat. Install and run the Rinnai in Sept/October/Nov and again in the late wintertime spring. Don't fire the oversized boiler until you have a sufficient load so the organization tin can operate efficiently, and I am saying seasonal/system efficiency, not rummage efficiency.

In my own habitation, my Rinnai has go my primary heat. My kids are grown and gone simply we are still living in the big 4 br house. I take 3000 or then sq ft but we really live in 750. I have a 556WTA (eight,200-21,500btu) in that 750 sq ft that I have had on since early Sept. The Buderus boiler is nonetheless off. It is in the 40's at nighttime here, simply we still need estrus, but I'll be damned if I'll light upwards the banality yet. It doesn't make sense. Don't get me wrong. I honey the large blue box in the basement merely I but don't need it yet. As an experiment, I'm really going to install another Energysaver at the opposite cease of the kickoff floor. By doing so i will take less than 1-2 deg F temperature differential anywhere on the offset floor. I of the great advantages of the Energysavers is that they have a modulating burner and blower. As a event they volition satisfy the comfort demand only so long as they can keep to run. Therefore, they will run on the lowest burner/fan input to continue to circulate the air. My heater will start running total time in early Nov and it probable volition not shut down until sometime in April. By the way, the 556 is the only oestrus in that end of the house and it is over the unheated garage (well unless I'one thousand working down there. Oh, and...I took my first drive yesterday on that car I was talking about. A four year project.)

I've been selling these heaters in New England since 1991. I thought sure back so that in x yrs or then I would start to see replacement unit sales. It but has non happened. They are incredibly durable.

Rinnai is the largest gas appliance manufacturer in the world. They build their own burners, hx, gas valves and they brand their own pcb'due south. The functional reliablity is but incredible. No they are not perfect, but you put them in correct and they will last and last. Rinnai have been building modulating gas valves since 1985. Rinnai taught Veissmann and Buderus how to do it. That is true and yes, they were very expert students!

Didn't intend to go off qutie that long. I tin can go along and on as those who know me can attest...but "that is what is going on."
