What is the efficiency loss of a heat exchanger?
Radiantec : FAQ Frequently Asked Questions, Radiant Heat, Sy...Whenever you have a heat exchanger, you must have a temperature difference in order to force the heat to cross the heat exchanger barrier and go to the other fluid. No heat is really lost, but the heating unit may run a little less efficiently at a the higher temperature.

Blaze King FAQ's Frequently Asked QuestionsBlaze King gas appliances are unique to the industry in that most Blaze King gas models have heavy-duty heat exchangers. Superior engineering and design has allowed Blaze King to fit the maximum amount of square inches of surface area of heat absorbing steel into each model. The more surface area of steel, the more energy absorbed during the combustion process. Then, the variable speeds fans that are standard in all gas models then moves that heat into your home.

Hi-Ho Petroleum: Frequently Asked QuestionsUnfortunately, there are three kinds of service companies out there. The kind that just wants to sell you something whether you need it or not, the kind who are just plain incompetent and there are companies that only sell you what you need, like Hi Ho Petroleum. One good rule of thumb is to get a second opinion. Anyone who pressures you to replace a part might not have your best interest in mind. On the other hand, your equipment may be dangerous to operate.

HVAC For Life : : FAQ Tips and AdviceThe heat exchanger is the area of the furnace where "heat" is exchanged-from the fire at the gas burner to the air that is recycled into the home through the duct system. The heat exchanger is sealed so that the products of combustion from the gas burner never come into contact with the air that goes back into the home.

Related QuestionsWhy don't I get as much heat out of my new high efficiency furnace?
Kidder Heating and Air Conditioning, Inc.Actually, you get more heat out of every dollar's worth of gas you buy with a high efficiency furnace compared to a 15-20 year old furnace. What you're probably referring to is the temperature of the air coming out of the register. This feels cooler because of the increased volume of air on your new furnace, therefore it feels cooler because the temperature rise is not as great.
Related QuestionsWhat is the efficiency of the atmospheric upward heat convection process?
AVE - FAQThe efficiency of the atmospheric process is the Carnot efficiency calculated using the average temperature at which heat is received as the hot source temperature and the average temperature at which heat is given up as the cold source temperature. Taking the average temperature of the hot source as +20?C and the average temperature of the cold source as -20?C, the efficiency is 14%. 14% of the 128 W/m2 transported upward by convection is converted to work.
Related QuestionsIs there efficiency loss in winter?
Frequently as questions about heat pumps and their applicati...Yes. Air source heat pumps draw their heat from the air. In winter the efficiency is reduced as there is less heat in the ambient air. We take this into consideration with our sizing. Even in these colder conditions our heat pumps are still more efficient compared to most other forms of heating. Our heat pumps for hydronic floor heating have proven to be very effective operating in colder air temperatures and achieving hotter water temperatures.
Related QuestionsWhat is the best type of steam trap to use on a shell and tube heat exchanger?
Frequently Asked QuestionsFor most heat exchanger applications, a Float & Thermostatic (F & T) Steam Trap works best. Because our F & T Trap has a separate thermostatic element, it is able to quickly vent air from the shell of the heat exchanger. The float element modulates to drain condensate at a rate equal to the condensing in the heat exchanger.
Related QuestionsHow do I avoid heat loss?
FAQsTo avoid this in the cooler months, manage the airflow according to the number of people in the space, ideally using automated controls, so that if the room is almost empty the airflow is kept very low. Keep the ventilation running to manage the smoke. Don’t let the smoke build up and then blast cold air.

Related QuestionsWhat does heat loss mean to me?
MAXX-R Pipe Insulation System FAQMore heat loss = more wood burned. Let???s assume that your system is designed to give up 15??F across the hydronic heat exchanger located in your home. If you have a 15??F drop in temperature from your furnace to the home and a 15??F drop from the home back to the furnace, you have used enough energy to heat 3 homes just like yours. Plus, you are probably loading your boiler 3 more times than necessary.
Related QuestionsCan I measure this heat loss?
MAXX-R Pipe Insulation System FAQActually, you can. Turn off all inside hydronic heat exchangers and use a hand-held infrared heat sensor (available for a low cost at many hardware building supply) to measure the temperature on the feed and return lines at the boiler. Feed pipe temperature minus return pipe temperature tells you your heat loss. The insulation on your boiler???s feed and return lines is not doing its job ??" and you are probably experiencing an extreme drop in water temperature.

Why does the heat exchanger air temperature feel cooler than a direct flame burner?
Dryair - Heat - Thaw - Cure - Dry - KillThe DRYAIR Heat Exchanger has been designed to eliminate "Hot spots" in a building by using high air flow. Example: a direct flame burner of equivalent size or rating will output 236 L/sec of air at 205 °C while a DRYAIR PHE-60EU portable heat exchanger will output 1,085 L/sec of air at 49 °C. This is an equal amount of KW output, but the effect is different.
Related QuestionsAre air conditioners and heat pumps efficiency rated?
Air Conditioners - Frequently Asked QuestionsYes. Central systems are rated by the seasonal energy efficiency ratio (SEER). Many older systems now in use have SEERs of 6 or below. By 1994, the average SEER for all units shipped by manufacturers in the U.S. improved to 10.61 for central air conditioners and 10.94 for central heat pumps. The higher the rating, the more efficient the system.

Related QuestionsIs heat loss a problem with high ceilings?
Frequently asked QuestionsThe height of the ceiling is not the problem in heating any house. Getting access to the heat already generated is the problem. Even with a low 2.4m ceiling two thirds of all heat is in the top third of the room, and as we don’t live in the top third we can’t enjoy the existing warm air without some form of mechanically mixing the air. The best and most cost effective way is with a ceiling fan.
