Why does the heat exchanger air temperature feel cooler than a direct flame burner?

Dryair - Heat - Thaw - Cure - Dry - Kill
The 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.

What is a heat exchanger and how does it work?

Blaze King FAQ's Frequently Asked Questions
Blaze 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.

Why does the burner or pilot flame go out?

Foyers Cadieux Heating Services Gatineau Aylmer Outaouais Fi...
Solution: The exterior termination cap on your exhaust system must constantly be free of any element that could block it, such as snow, ice, bird nests, etc. Sometimes, wind may cause a turbulence zone that will cause the burner and the pilot to shut off. If your burner or pilot flame has gone out during a very windy day, there may be nothing wrong with your fireplace. Simply re-light the fireplace. Solution: B-Vent gas fireplaces have a thermal switch.

What can I expect the discharge air temperature to be from my evaporative cooler?

FAQ
That depends on a number of factors. The discharge temperature is determined by the temperature and relative humidity of incoming air. To determine the temperature of the air leaving the cooler, you will need to know the outside dry bulb temperature, the current outside wet bulb temperature, and the evaporative efficiency of the evaporative cooler (typically provided in product brochures under Performance Data). This should provide a guide to approximate discharge air temperatures.

I was told that I need a new heat exchanger, how do I know that I'm not being taken advantage of?

Hi-Ho Petroleum: Frequently Asked Questions
Unfortunately, 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.

What is a cracked heat exchanger?

HVAC For Life : : FAQ Tips and Advice
The 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.

What are the heat exchanger loop pipes made from?

JustGeothermal Systems Website - FAQ
Geothermal earth loops are made from High Density Polyethylene, (HDPE) pipe. The circuits are either 3/4" or 1 1/4" diameter and headers are either 1 1/4" or 2" diameter. The resin is PE 3408 having a cell classification, 345564 or 345434 per ASTM Standard Specification D3350, certified as being in accordance with CSA Standard B 137.1. This is the specification referred to in CSA 445 and CSA 448 and thus is mandated by Canadian Building Codes.

Which evaporative cooler should I use and what would be the temperature?

Summary: The output temperature will depend on the ambient temperature and humidity. See the Humidity Index if you know the range of your typical ambient temperature and humidity. Basically all Swampys except the Ice Models operate the same so choose the one that fits your needs regarding dimensions, airflow direction & use.

Why would I need an air exchanger for my home?

Broan - Catalogs
The air circulation within your home may be good, but more likely the air quality is poor. It's damp, stuffy, or making you sick. Replacing appliances such as a furnace or water heater, installing new windows or adding siding to a home changes the air leakage rate. Any improvements made to a home that reduces airflow in a house may result in insufficient natural ventilation. Excess moisture destroys your windows and building structure.

Where is an air exchanger installed?

Broan - Catalogs
The HR 2.5 and HF 3.0 units require a floor or pipe drain to evacuate the water produced by the functioning of the unit. They should be installed within an area of the house where the ambient temperature is above 10°C) (basement, furnace room, closet, etc.).

Why does the bath temperature heat up above room temperature when the heater is not switched on?

Brinkmann Instruments, Inc ::: FAQs-Temperature Control
A portion of the heating thermostat pumps' electrical energy is lost to the bath liquid in the form of heat. Pump output flow, thermostat insulation, and the type of bath liquid used may affect the increase in bath temperature. Some bath temperatures can increase as much as 70°C above ambient temperature; however, Lauda® Ecoline Circulators only heat the bath slightly above ambient temperature when the lowest pump flow setting is selected. Yes and no.

Question: Will the flame operate without heat?

Welcome to Downtown Electric Fireplaces
Answer: Yes! The flame and heater operate independently of each other. This means you can enjoy the ambiance of of a realistic flame all year round!* *In many gas units, the flame cycles off as the room temperature rises and you lose the flame effect until the room cools down again. In smaller rooms, gas fireplaces can be off a lot of the time and in the warmer climates they may not come on at all unless the thermostat is set higher than the room temperature

Why does the bath heat up above the ambient temperature when the circulator is not switched on?

Brinkmann Instruments, Inc ::: FAQs-Temperature Control
Every circulator incorporates a circulating pump, which ensures thorough mixing of the bath liquid inside the bath and also pumps the bath liquid through an external circuit. The electrical energy taken up by the driving motor passes as thermal energy into the liquid, which leads to a slow temperature rise inside the circulator up to the so-called intrinsic temperature. The intrinsic temperature depends on the pump output, the insulation of the circulator, and on the bath liquid used.
Related Questions

Can I increase the pressure on my burner to get more heat release?

John Zink: JZ Burner Parts & Service
Not usually. Capacity is limited by the amount of air that the burner can pass. Increasing pressure to pass a larger quantity of fuel, when insufficient air exists for the larger capacity, can be dangerous. In some cases, increasing fuel pressure above the maximum can cause burner instability. Further, the need for increased pressure may signal dirty (fouled) tips, which can also lead to burner instability.
