Choosing the Perfect Natural Gas Or Propane Unit Heater For Your Garage Or Workshop at MicroTempUSA

January 2nd, 2017

[ad_1]

Fan forced natural gas and propane garage heaters burn fuel in a heat exchanger to produce heat. Natural gas unit heaters are very common in populated areas that have natural gas piped throughout neighborhoods. Propane unit heaters are typically used in rural areas where natural gas is not available.

Operating Principle

When there is a need for heating, the fuel from your natural gas line or propane tank flows through a gas valve inside the unit heater. A spark or pilot flame ignites the fuel and a flame is produced inside a heat exchanger. When the heat exchanger reaches a pre-set temperature, a fan turns on which blows space air through the warm heat exchanger. The air entering the heat exchanger absorbs the heat from the heat exchanger, resulting in a warmer discharge air temperature. As the fuel is burned, by-products of combustion leave the unit heater through a vent pipe also called a chimney.

Benefits of fan forced gas or propane unit heaters in garages or workshops:

oEfficient.

oPowerful, fast self contained heat producers. They don’t rely on a centralized boiler to supply heat.

oLow clearance requirements on low profile units.

oMost units have adjustable louvers to help direct warm air where you need it most.

oDurable. All unit casings are treated for corrosion resistance and finished with a baked-on, high solids paint.

oHuge range of sizes and styles to match the heater to your heating load. If selected properly, you don’t have to worry about under or over sizing.

oThe fan can run in the summer without heat to help circulate air.

oNatural gas units are always ready to run. You don’t need to worry about replenishing your fuel supply.

Drawbacks of fan forced gas or propane unit heaters in garages or workshops:

oGas fired units require more maintenance and service then other types of heaters.

oBy-products of combustion require special attention. If the heater is not vented properly, dangerous fumes can enter your garage or workshop.

oClearance requirements must be met. A flame is present. You must be sure combustible materials (fixed or airborne) stay away from the unit heater.

oDirty, dusty or corrosive atmospheres require special attention.

oFan forced units move large volumes of air which can kick up dust in your garage or workshop.

Unit Configurations:

Gas and propane unit heaters for garages and workshops blow air horizontally into the space. Adjustable louvers allow for vertical adjustment of airflow. Most major manufacturers also offer horizontal louvers that allow for side-to-side adjustment of airflow. Gas and propane unit heaters for garages and workshops can be broken down into several categories based on the venting type and heat exchanger design:

Venting Types:

Good: Gravity Vented

Due to its low cost and compact design, gravity vented propeller unit heaters are a good choice for some garages and workshops. The term gravity vented refers to a unit heater that vents naturally, without the assistance of a fan. A gravity vented unit uses the air in the garage or workshop for combustion. The warm by-products of combustion rise out of the unit heater through a flue pipe to the outdoors. A gravity vented unit is the least expensive style; however, you must be sure the following conditions exist:

1) Your garage or workshop can not be under a negative pressure. If your space is negative, the by-products of combustion will not vent properly and you will experience nuisance tripping from a safety switch that senses a blocked flue vent. Negative pressures occur when air is being exhausted from a space without any source of make-up air. Gravity vented units can be very sensitive to pressure changes. Sometimes a bathroom exhaust fan turning on can be enough to trip off a unit. If you have a gravity vented unit that is experiencing nuisance trip outs, you may want to install an aftermarket power venter that gets installed in the flue vent pipe to help push the by-products of combustion in the right direction.

2) Specific vent pipe routing is required. Gravity vented units operate on the principle that hot air rises. Vertical venting through the roof of your garage or workshop is preferred. Sidewall venting is more difficult. Venting through a roof can become more expensive since you need to completely weatherproof the hole in the roof. The manufacturer’s detailed installation instructions must be followed closely.

3) Since the air inside the heated space is being used for combustion, it is important that the atmosphere is clean. If you are comfortable lighting a match in your garage or workshop, then you should feel comfortable about running a gravity vented unit in your space. If there are any combustible dusts (woodworking shops) or fumes in your garage or workshop, choose a separated combustion design which is explained below.

Better: Power VentedA power vented unit is very similar to a gravity vented unit with the addition of an integral flue vent booster fan. On a call for heat, the booster fan turns on to ensure the by-products of combustion will be vented properly. Power vented units are the most popular type of gas and propane unit heater for garages and workshops. The booster fan allows for greater flexibility with flue pipe routing. Horizontal venting is very easy. In a garage or workshop, most venting is done through a sidewall to avoid costly roof modifications. Many of the major manufacturers are phasing out gravity vented units and are replacing them with power vented units as their entry level product.

Best: Separated CombustionSeparated combustion units are rapidly gaining in popularity. While traditional gravity and power vented units utilize space air for combustion, separated combustion units are sealed from the space. Separated combustion units for garages and workshops have 2 flue vent pipes. 1 flue vent pipe draws in air from the outdoors and 1 flue vent pipe exhausts the by-products of combustion back outside. This sealed combustion design eliminates you concerns about burning the air in your space. Separated combustion units are a must in your woodworking shop where fine dusts can ignite with an open flame. Separated combustion units are usually slightly more efficient since they do not use the heated air in your space for combustion.

The only drawback to a separated combustion unit in your garage or workshop is the 2nd vent pipe. A 2nd vent pipe requires a 2nd hole in your wall or roof. Most manufacturers offer concentric vent kits that allow the 2 vent pipes to join at a galvanized metal box on the interior of your garage or workshop. The box combines the 2 vent pipes on 1 end and diverts them into a pipe within a pipe on the discharge end. This allows you to only penetrate your wall or roof once. This also can make your unit more efficient as the warm flue exhaust warms the cold outside intake air.

Heat Exchanger Designs:

Traditional natural gas and propane garage and workshop heaters are tall and narrow. Most manufacturers are transitioning towards the newer tubular heat exchanger design. Tubular heat exchanges are more flexible and resist cracking over time. This design also allows the unit to be wider and shorter which is necessary for most garages and workshops that do not have ample overhead clearance.

Standard natural gas and propane garage and workshop heaters come with aluminized steel heat exchangers. Aluminized steel is more then adequate for typical garage and workshop installations. The life expectancy for a natural gas or propane unit heater in a clean environment is 20+ years. If your application involves high humidity levels or mildly corrosive atmospheres, your natural gas or propane garage heater will last a lot longer if you upgrade to a stainless steel heat exchanger.

Options and Accessories:

Natural gas and propane garage and workshop heaters have several options and accessories to help meet your specific requirements. High CFM blowers, 2 stage units, wall mounted thermostats, air deflectors and vent caps are very common accessories used in garages and workshops. If you’re not sure what to order, call us and we will recommend a unit to meet your specific needs.

Installation Overview:

1) Suspend the unit heater using threaded rods or angle iron. Some of the low profile units include angle iron for mounting your unit directly to the ceiling.

2) Install natural gas or propane piping.

3) Install vent pipe.

4) Wire a low voltage wall thermostat to the heaters terminal strip.

5) Wire the high voltage power required to operate the heater. This is usually 120 volt power in garages and workshops.

Commonly Asked Questions:

1) How do I calculate the heating load for my garage or workshop?

ANSWER: There are many free heat load calculator tools available on the internet. Do NOT fall for equipment that is advertised as “will heat up to 400 square feet”. Heating a 400 square foot insulated garage in Florida is a lot different then heating a 400 square foot un-insulated metal garage in Maine. 1 heater can not magically service both 400 square foot spaces. You do not want to undersize, and you do not want to oversize.

2) How do I control my natural gas or propane unit heater in my garage or workshop?

ANSWER: A wall mounted 24 volt thermostat is required. When there is a call for heat, the thermostat sends a signal to the natural gas or propane heater to turn on. Upgraded thermostats include a “fan” switch which allows you to operate the fan with no heat in the summer.

3) How do I determine how much heat a natural gas or propane unit heater will generate?

ANSWER: Natural gas and propane unit heaters for garages and workshops are listed by their fuel inputs. For example, a 100,000 BTUH unit will consume 100,000 BTU’s of fuel per hour. The actual heating output depends on the unit’s efficiency rating. If the unit is 80% efficient, the actual heat output will be 80,000 BTU’s per hour. Do not pick a heater based on the nominal size. Many people think this is the actual heat generated by the unit. They end up with a unit that is undersized.

4) What is the best location in my garage or workshop to install my natural gas or propane unit heater?

ANSWER: The natural gas or propane unit heater in your garage or workshop should be located in the coldest area, and it should be angled slightly so it blankets warm air across the coldest wall.

5) What is the best location to install a wall mounted thermostat in my garage or workshop?

ANSWER: The thermostat should be mounted in a location that represents a good average temperature in your garage or workshop. If it is located in a cold spot, it will falsely run the unit heater more then it should. If it is located in an area that receives direct sunlight, it will falsely run the unit heater less then it should. A well insulated interior wall is the best spot for the thermostat.

6) I have a natural gas unit heater that is 30 years old and in perfect condition. How do I convert this to propane?

ANSWER: Most manufacturers will only produce parts for equipment that is 20 years old. After 20 years, it is assumed the unit will be replaced with newer, more efficient technology. In some situations, you may be able to contact the manufacturer of the gas valve directly for an aftermarket conversion kit.

7) How can I compare the cost to operate natural gas, propane, oil and electric unit heaters?

ANSWER: There are manyh energy cost calculators available on the web. Pull out your latest utility bill and use this information to run an analysis.

8) What is included in a natural gas to propane conversion kit?

ANSWER: Different fuel types operate at different flow rates and pressures. The springs and orifices inside the gas valve needs to modified to match the fuel type. On some equipment, the igniter also requires an upgrade.

9) How do I decide if a separated combustion natural gas or propane garage or workshop heater is required?

ANSWER: If you’re not comfortable lighting a match in your space, then you need a separated combustion unit so that there is no open flame being exposed to the heated space.

10) How do I vent my natural gas or propane garage or workshop heater?

ANSWER: You must carefully read the installation instructions for your specific heater. Manufacturers do a good job outlining common practices. Local codes may dictate venting requirements and override the manufacturer’s recommendations. It is not a good idea to buy your vent pipe in a “kit”. There are several types of vent pipe, and the inexpensive kits that are designed to fit all installations don’t always form a perfect seal. A kit that offers “flexibility” means there are a lot of expandable pieces and joints that need sealing. The fewer joints you have, the safer your system will be. Hang your heater in the best possible spot for comfortable heating. Draw a sketch of the venting required and bring it to you local plumbing or home goods store. They will know your local codes, and they will select the pieces in the longest lengths available. This saves a lot of extra joints that can be very dangerous if they are not sealed properly.

10 Steps to a Perfect Barbecue at MicroTempUSA

January 2nd, 2017

[ad_1]

There may be no such a thing as a perfect barbecue, but there are steps you can take to make certain the next barbecue party you host flows smoothly.

1. Make sure your gas tank has enough gas. Nothing ruins a barbecue quicker than running out of gas while grilling. It’s nice to have a backup tank on hand but it’s even better to know there is plenty in the tank you are using.

2. Have all cooking utensils on hand, including a meat thermometer. You should have your serving trays nearby. Nothing is more frustrating than having the meat ready to come off the grill and not being able to find a dish to put it on.

3. Meats should be completely thawed ahead of time and ideally should be sitting at room temperature for about a half an hour. This will help the meat cook evenly.

4. If grilling tougher meats, such as flank steaks, you should marinate before hand to tenderize the meat. To tenderize, the marinade must contain some lemon juice, vinegar or wine. The tougher the meat, the longer they should be marinated, so you may want to marinade overnight to play it safe.

5. Try to keep the meat cuts at similar thickness, especially when grilling steaks. Too many different thicknesses will make your grilling chore much tougher.

6. If you are grilling chicken or pork, you need to be certain the inside is thoroughly cooked. Use a cooking thermometer. The inside temperature should be about 175 degrees.

7. Reduce flare-ups by trimming your meat ahead of time. When you are cooking a lot of meat at one time, it gets harder to keep the flames from burning your food. Grilling at a lower temperature can help, particularly with the control you get with the new gas grills. If you have 3 burners or more, it may help to turn off one burner. When a flare-up starts, remove the meat from that area of the grill to the unlit burner. Of course, when the grill is crowded with meats, it may take some shuffling. Move the meats to the warmer rack if possible and, if all else fails, remove the meats from the grill, close the cover and let the flames burn off.

8. If you are using barbecue sauce, don’t apply it until the last 5 minutes of grilling. Turn down the heat and add the sauce. This will minimize the chance of burning.

9. Timing is important. Although meat will continue to cook once removed from the grill, turning off the grill and letting the meat sit in the grill to keep it warm while waiting for side dishes to cook can dry out the meat. It’s much easier to keep the beans warm a little longer than it is to try to keep the meat from overcooking. If you figure it will take 20 minutes to grill, don’t start grilling until the other dishes are about 15 minutes from completion.

10. If you need to grill a second batch of meat, start it immediately before you start to eat. The grill is hot and ready to go. Get the next batch on so you can finish about the time the first batch runs out.

Follow these tips and your next barbecue party will be your best.

Roasting Recipes – Roasting Meats at MicroTempUSA

January 1st, 2017

[ad_1]

Roasting is the cooking of foods at high temperature typically in an oven or a pit. The main difference between roasting and baking is that baking uses a lower cooking temperature and takes longer.

In fact roasting is probably one of humanity's oldest cooking techniques as all that it takes to roast meat is to place it directly on the fire. The meat is tenderized and becomes tastier and easier to digest. It probably was not long before our hunter-gatherer ancestors found that it was not the fire itself but the heat of the fire that cooked the meat. Thus strips of meat and vegetables would be hung on sticks above the fire. They also found that hot rocks cooked just as well as an open fire and that food buried in a pit with hot rocks roasted very nicely and tasted better as the food steamed as well as roasted.

These roasting pits are the fore-runners of modern ovens and the use of roasting for all kinds of foods is still alive and well today.

Below, two classic roasting dishes are presented:

Roast Pork with Fennel Seed

Ingredients:
1 belly of pork
2 tbsp fennel seeds
1 tsp fresh rosemary leaves
1/4 tsp fresh thyme leaves
10 garlic cloves
sea ​​salt and black pepper to taste

Method:
Score the skin of the pork with a sharp knife then remove any ribs from the underbelly (but reserve) and remove the skin in one piece (this is critical). Add the fennel seeds to a pestle and mortar and pound to a powder. Add the garlic and form a paste. Then add the other herbs and pound in along with plenty of seasoning. Use this mixture to spread over the de-skinned meat then put the skin back on top of the paste. Roll this up (with the skin on the outside) and secure with string.

Drizzle a little oil in the bottom of a roasting tin, add the pork bones on top of this and then palace the rolled belly of pork on top. Place in an oven pre-heated to 135 ° C and cook for two hours. Leave the meat to rest for at least half an hour then transfer to a serving plate.

Roast Welsh Lamb

Ingredients:
2 kg leg of lamb
Salt, black pepper
Level teaspoon of ginger
Large tablespoon of honey
Rosemary
Bottle of dry cider

Method:
Rub the lamb all over with salt, pepper and the ginger. Spread the honey over it and sprinkle with 2 level tablespoons of chopped rosemary. Place the joint in a deep close fitting pan and pour the cider to come about 5 cm up the pan.

Roast the lamb for 1.5 to 2 hours in an oven pre-heated to 160 ° C, basting occasionally.

Transfer the lamb to a hot dish and let it rest for 15 minutes before carving. Strain the juice into a wide shallow pan and reduce by boiling to make well-flavoured gravy. Serve with boiled potatoes and tender seasonal vegetables.
