Detroit Radiant DSRF-30 Vented Tube Heater: overhead patio heat with exhaust that can vent outside
The Detroit Radiant DSRF-30 Vented Tube Heater is a gas heater for covered patios. Its black coated tubes are steel coated with aluminum. It is 16 feet 4 inches long, weighs 170 pounds, and hangs from a ceiling or canopy 9 to 16 feet high. It runs on a piped gas line, natural gas or propane, so there is no tank to refill. Detroit Radiant Products is a family owned company founded in 1955 that builds its heaters in Warren, Michigan.
Radiant heat warms people and surfaces directly, like sunshine, instead of warming the air, so it works outdoors. It warms about 26 by 12 feet. Exhaust can be ducted outside rather than drifting under the canopy. Choose 65,000 BTUs (50,000 on low) or 80,000 BTUs (52,000 on low), plus your gas type. It drops to low once the patio warms. Warranty coverage is three years on components, five on tubes, and ten on the burner. Need more length? See the Detroit Radiant DSRF-35 Vented Tube Heater. The Detroit Radiant DSRF-30 Vented Tube Heater ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

Applications
Application by Industry
Use radiant heat in a variety of hard to heat applications. Infrared heats people, floors, walls and other surfaces directly without heating the air first, which is why it works where forced air fails. Tap an industry to see how Detroit Radiant heaters are used there.
Agriculture
Low intensity radiant tube brooders and high intensity brooders.
Infrared heaters are widely used in swine, poultry, brooder and dairy barns because they have a long record of proven results. Two stage heaters add efficiency and several benefits: lower running costs, less on and off cycling, more fuel saved, the ability to change the heat output, and better animal comfort. The result is better animal performance, less fuel burned and a longer heater life.
- Save 20 to 50 percent on the fuel bill with radiant tube heat compared with other heating appliances
- Cut annual maintenance by up to 90 percent
- Optional two stage operation for better comfort
- Quiet, clean operation
Aircraft Hangars
Heat large, hard to heat areas.
Gas fired infrared heaters heat efficiently because they warm exactly what needs to be warm: people, floors, walls and other surfaces, instead of the air. That suits hangars with huge air volumes or lots of air movement, where warm air heating is wasted because it must first heat all the air, which rises before anything else does.
Equipment selection: high BTU tube heaters or high intensity models are made for high mounting spots like hangars. Two stage heaters recover the heat lost through the big doors, then cycle less during normal operation. Most of the heat should be concentrated near the main door with burner boxes or extra heaters. ANSI/NFPA 409 calls for the heater to sit at least 10 feet above the highest wing surface of any aircraft stored inside.

Automotive
Efficiently heat open door service areas.
Most service garages and vehicle maintenance shops have a lot of open door area for their size, and cold vehicles keep rolling in. That makes infrared the economical way to heat the space. When placing heaters, keep them away from overhead doors and vehicle lifts, keep the published clearances from hose reels and exhaust collection systems, and never put a heater inside a paint booth. In smaller areas where tube heaters are not practical, a forced air unit heater can fill in.
Detroit Radiant recommends low intensity tube heaters with outside air supplied to each heater where degreasers, parts washers or rust proofing are used, plus mechanical ventilation at floor level, since most chemical fumes are heavier than air. Most centers use 75,000 to 150,000 BTU tube heaters in a perimeter layout, with extra units or burner boxes stacked at the door areas.
Commonly used products
- REV Series two stage low intensity
- HL3 Series two stage low intensity
- DX3L Series single stage low intensity
- MP3 Series modulating low intensity
- DR Series high intensity
- FA and UH Series separated combustion unit heaters
Car Washes
Save energy while heating harsh environments.
Short tube heaters with high BTU ratings, or small to mid size high intensity heaters, are the efficient choices for a car wash. Most car wash heating systems are designed to protect against freezing and to spot heat employees, so the heaters are best placed at the ends of the tunnel. Millivolt controls are the usual pick for equipment rooms, if shielded from the wind, so freeze protection keeps working during a power outage.
Stainless steel, silicone sealant, waterproof controls and electrical attachments are recommended, and two stage operation adds further energy savings.
Commonly used products
- Stainless steel low intensity tube heaters
- DR Series high intensity
CNG Facilities
Heating vehicle maintenance facilities.
Natural gas is an affordable, abundant fuel for fleets, and Detroit Radiant has the experience to heat compressed natural gas (CNG) vehicle maintenance facilities. The company offers a range of options and can usually turn around concept drawings within a few days.
CNG shops must comply with special requirements such as NFPA 30A, which says the heater surface temperature must not exceed 750 degrees F. Detroit Radiant's CSA design certified heaters meet the construction criteria the code requires. When the space needs more burners than will fit, the engineered HLV vacuum system can be used in the design.

Outdoor
Gently warm people and furnishings, not the air.
Whether you want to extend the outdoor season, heat a designated smoking area or add room for peak crowds, Detroit Radiant's range has an outdoor heater to fit.
- Air movement: wind, even a light breeze, is the biggest variable in outdoor comfort. Barriers such as wind curtains are highly recommended wherever possible, but always keep the clearances to combustibles.
- Mounting heights: outdoor and spot heating usually means mounting the heater lower, closer to the people. A lower mount covers less area but gives a more focused heat pattern, so the final height may need adjusting to get the result you want.
- Your expectations: there is rarely a one size fits all answer. Maximum comfort in extreme conditions takes more heaters; taking the chill off a smoking area for a few minutes takes fewer.

Spot Heating
Heating only a portion of a building? Detroit Radiant offers great options.
When only part of a building needs heat, consider spot heating. Both high intensity infrared heaters and low intensity tube heaters suit it. Tube heaters are usually placed in a U shape for spot heating: the U puts the hottest tube next to the coolest tube for even comfort and gives the most flexibility in placement.
High intensity heaters are usually easier to install and cheaper for spot heating. They are especially suited to buildings that are poorly insulated, loosely built, have high ceilings or lose a lot of heat per square foot.

Warehouses
Strategically placed for the best coverage of the space.
Detroit Radiant offers many cost effective options for heating a warehouse. When choosing equipment, consider the warehouse type, its size, the mounting heights, the level of insulation and any other design features that affect the heater choice. Tube heaters give plenty of placement options with regard to clearances and are usually thermostat controlled.
Place warehouse heaters for the best coverage: a perimeter layout, or a series of heaters between rows of storage racks. Whatever the layout, mind the clearances to combustibles, especially above and below the heater where stacked goods are a concern. Detroit Radiant recommends warning plaques (part PLQ) to advise users of the clearances and stacking limits.

FAQ
What does vented mean on this tube heater?
The DSRF is the vented version of Detroit Radiant’s low-intensity tube heater: its combustion products can be ducted out through a vent instead of released under the canopy, which is why the brochure recommends it for driving ranges and restaurant patios that need a vented solution. It is CSA certified for commercial indoor and outdoor use and residential outdoor use only.
How long is it and how much heat?
16 feet 4 inches of housing with 28 linear feet of radiant tube per the brochure, and a Heat Output selector of 65,000 BTU per hour with 50,000 low fire or 80,000 with 52,000 low. Natural gas or propane is chosen on the Fuel Type selector. It weighs about 170 pounds and ships by truck on a skid.
How high should it hang?
The brochure gives 9 to 16 feet mounting heights at 0 or up to 30 degrees, with clearances at 0 degrees of 25 inches to the sides, 6 inches above and 60 inches below. A hanging kit is included; the Accessories selector adds turnbuckles, Gripple cable and 2-point hanging bracket kits sized for 21 to 32 or 34 to 45 inch drops.
What power does it need?
A 120 volt, 60 Hz supply with a power cord standard and 24 volt controls; amps are 4.8 starting and 1.1 running. Ignition is hot surface, and the microprocessor circuitry runs pre- and post-purge cycles with a self-diagnostic LED, per the Features tab and brochure. A stainless flexible gas connector is included.
Can I duct the exhaust and intake?
Yes. The DSRF is certified for vented operation, and the DSRF manual linked in the Manuals tab covers the vent run, which it reserves for trained gas installation personnel. The Accessories selector adds a 4 inch air intake extension with cap; the exhaust kit listed there is the vendor’s kit for running the heater unvented instead, not venting parts. Browse other commercial patio heaters for unvented alternatives.
What is the warranty?
3 years on components, 5 on the radiant tubes and 10 on the burner, per the Specifications tab and brochure. The tubes are .95 emissive black-coated aluminized steel over a 4 inch aluminized combustion chamber, and the manual calls for an annual inspection to keep the heater in warranty.

What Our Customers Say
D
A sauna turns your garden into a spa oasis. We debated it for a while, but after renovating our house, we pulled the trigger and bought a sauna from Norse Steam and Maya. She was always super responsive and helpful throughout the process. Don't kid yourself, getting a really nice sauna is not that easy. Sizing and heating need to be figured out, as does the building, but we have always had a helpful partner on our side. She never upsold us on anything we didn't need, and we got some nice freebies when the sauna was delivered. And now we can really enjoy every moment in our garden.
KF
I'm really happy with my sauna purchase. Maya gave above and beyond excellent customer service. She wasn't pushy and gave impressive followup after the delivery to make sure everything was just right.
DE
I enjoy my FD2 Sauna with Red Light, Infrared and radiant heat. Use it 5x a week and my post workout soreness is minimal and sleep great. Maya at Norse Steam was excellent to work with.
B
We purchased the 3-person sauna for our outdoor garden. We chose the cube sauna for the aesthetic and could not be happier.
I assembled by myself except for the 2 large panels (requires a few people). Instructions were good - took me two partial Saturdays to complete and a few hours to unpack and organize in advance of assembly. Had my elec. add a NEMA enclosure on the back for the controller and power for lights and a 2nd panel for the wireless control.
Customer service was excellent
MP
Awesome Sauna and Awesome Company and Experience purchasing it from Maya!

EA
Recently purchased the Finnmark one person after much research. Extremely happy with it and the ordering process. Maya was very responsive and helpful during the process and keeping us updated while we waited for shipment. There were several places I could have ordered this, but i chose Norse Steam based on the communication and customer service which was fantastic. The shipment was also excellent. The setup was pretty seamless for two people - but the best part is the sauna experience 10/10
G
Maya is amazing - super helpful and responsive. Looked at many stores, these guys have the best prices and service. Highly recommend
GR
Norse Steam, and specifically Maya, were extremely helpful as I was making the decision for our Sauna. I was able to get all of the necessary details to make a decision as construction was happening in my backyard to make space for it.
We absolutely love the CL7G. It is extremely comfortable for 6 people (can fit more less comfortably). The Thermory Spruce and Aspen in the interior smells great. The lighting is lovely. We paired the CL7G with the Harvia Spirit 10.5kw.
RS
Had great experience shopping at Norse Steam for the new heater. They had very good deal, with rocks. Customer service was good, and responded very fast with my questions. Received the heater, and it looks good, and the quality seem to be great. Will install soon, and am very excited to start experiencing sauna the way it ment to be

Smoking Hot Tub!
I got the Norse Steam SaunaLife wood-fired hot tub, the S4N model, and its been seriously great. It heats up quicker than I expected, usually around an hour and a half, and once its hot, it stays that way for a good long while. The wood-fired system is simple to use, and honestly kind of fun.
The tub itself feels solid and well put together. The thermo-spruce exterior looks beautiful in person, and the fiberglass interior is smooth, deep, and easy to clean. Its the kind of setup that just works without a bunch of fuss, which I really appreciate.
Also, the team at Norse Steam was genuinely great to work with. Super helpful, quick to respond, and made the process really easy from start to finish. It felt like they actually cared that I was happy with it. The tub has totally become a go-to way to unwind, and I wouldnt change a thing.
S
Maya was so knowledgeable and responsive
Maya was so knowledgeable and responsive. She helped me understand the product options and found a fantastic solution that fit our needs. Her follow through was very helpful and made us comfortable with our decision. We are extremely happy with the end result!

Great Sauna & Purchase Experience
Great experience purchasing Finnmark FD-2 from Norse Steam. Good communication and easy to assemble. Temperature increases quickly (30 minutes or less to 140) and maintains well. So far this has been a great purchase.
M
Great sauna and great customer service
We purchased the Finnmark SD-1 sauna. Maya was extremely helpful with the purchase. We had an issue with the sauna not reaching the maximum temperature, and Maya connected us with the appropriate technician that explained how to correct the issue. The sauna now heats to the maximum temperature (170 degrees) in less than an hour, and it is a great unit. We are very happy with it, and we would definitely purchase from NorseSteam if we needed any other items.
