Recently A lot of people have been stopping by our site searching for Value Engineering in the Chicago area. This is due because of the following we have develop in this types of projects. However, many builders from Harvey to Waukegan, IL, do not know that NY Engineers is also the ideal choice for anyone looking for HVAC Firm in or near Chicago, IL.

The quest for cost effective buildings involves energy-efficient HVAC system design. This will include systems for architectural enclosure, domestic water heating, lighting, HVAC, and vertical transportation. The loads for the HVAC systems should come primarily from 5 different sources including lighting (cooling), the property envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load might be a function of either the mechanisms required so as to introduce it right into a space and control contaminant concentration or the quantity of persons who will use the space. In the vast majority of climates from the southwestern and eastern regions of the US, to reduce outside air-flow can save energy whenever the

outside air is either humid and warm or very cold.
Governing the ventilation rate will probably be dependant on occupancy which is called a variety of demand control ventilation. It is a common type of energy conservation policy that is used for buildings with occasional or dense occupancy. Having heating and cooling loads dropped as low as possible can be achieved through the use of a high performance building envelope, occupancy sensors, and performance lighting that utilize daylight response of lighting controls.

Chicago HVAC Engineers versus HVAC Techs

If you have ever considered the distinction between a HVAC Engineers versus HVAC Technicians, then read on:

Chicago HVAC engineers would be the people who watch over the installation of air cooling systems for commercial and residential buildings. They spend plenty of their work in offices doing advanced level organization and preparation of installations however they do also visit job sites from time to time.

In comparison, HVAC technicians in Chicago tend to do more of the hands-on work with repair and maintenance. A HVAC technician may deal with an engineer to complete a few of the installation task, particularly for smaller jobs. In general HVAC technicians do a lot more travel and might spend time and effort identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems that utilize old refrigerants.

HVAC engineers could have a chance to make more decisions about systems that are being used, and so they will be the folks that would offer advice about by far the most sensible refrigerants and which systems would best suit a larger building. In the industry, there may be some competition between ‘the suits’ and ‘the ones which get their hands dirty’, but both jobs do require a great familiarity with how air-con does work. Lately many Internet users have been crawling the New York Engineers site searching for HVAC Supply House Chicago. With that said, the goal of our organization is to become the number one choice for anyone looking for a HVAC Companies near Chicago and or any of our other services including Protection Engineering services. We ask that everyone searching for more information about our Heating Cooling Air Conditioning Furnace (HVAC) Engineering Firm in Chicago Illinois takes a look at our blog!

Radiant Heating Systems: Types and Applications for HVAC Engineering

Architectural Engineering Requirements

Radiant heating systems deliver heat through the floor, walls or ceiling of a building. As implied by their name, these HVAC engineering systems rely mostly on radiant heat transfer – direct delivery of heat from a warm surface to occupants and objects via radiation.

Radiant floor heating systems are characterized by their silent operation and energy efficiency. Since the heat source is located below, temperature rise is uniform as warm air rises and displaces cooler air. This also allows heating to occur without a forced air system: the installation does not disturb dust and allergens, while improving occupant comfort by eliminating air drafts.

Radiant floor heating also offers a lower running cost than furnace-based heating systems – you can expect savings from 25% to 50% according to the US Department of Energy. Space heating is the highest energy expense in certain buildings, so projects that improve its efficiency tend to have an excellent return on investment.

Radiant floor heating is a great option for houses with children and for schools. Conventional air duct systems deliver heat from above, and the lower portion of the room is not always heated effectively because warm air tends to rise. Due to their shorter height, kids are more susceptible to uneven heating from forced air systems, and this can potentially lead to health issues. On the other hand, radiant floor heating delivers heat from the bottom up and improves comfort for kids.

Radiant heat systems are highly recommended HVAC engineering solutions in houses with big rooms and high ceilings. Conventional forced air systems are impractical in these cases, since they only tend to heat the upper portion of the room, wasting energy.

Types of Radiant Floor Heating Systems, Explained by an HVAC Engineering Pro

Radiant floor heating systems can be classified based on the medium used to deliver heat: air-heated, electric and hydronic.

1) Air-heated radiant floor system: In this system configuration, hot air is blown through the ducts beneath the floor, which causes a warming effect. The main limitation is that air cannot hold much heat, so these systems are not suited for residential buildings.

2) Electric radiant floor system: This configuration uses heating cables or conductive plastic mats that are built into the floor. The main limitation of electric radiant floor systems is their dependence on resistance heating, which can result in a very high running cost if the kilowatt-hour price is high.

Electric radiant floor heating works best for property owners that have access to time-of-use electricity rates and floors with a large thermal mass (e.g. concrete). The system can be configured to operate when electricity prices are low, which is normally during off-peak hours, storing as much heat as possible in the floor itself.

The system is also set to shut down during peak demand hours with expensive electricity, and the floor can deliver from 8 to 10 hours of heating without power consumption if its thermal mass is high enough. If the floor has a reduced thermal mass, the electric RFH system must operate more frequently, and running costs can increase dramatically during peak demand hours.

3) Hydronic (hot water) radiant floor system: This is the most popular and cost-effective among the three types of radiant floor systems, and is suitable for applications where occupants can use a thermostat to control the heat output room-by-room. Hot water from a boiler is pumped through hydronic pipes that are evenly distributed under the floor, and distribution among different piping runs is controlled through a manifold. Hydronic RFH systems have minimal maintenance requirements and can be installed between the joists under existing floors, making them ideal for renovations.

Radiant Floor Heating Installation Types

Radiant floor heating systems can be classified into wet and dry installations. Note that this classification is independent from the heat transfer medium: the words wet and dry to not make reference to hydronic piping or electrical resistance.

1) Wet installation: This is the oldest type of radiant floor installation. Electrical cables, mats or hydronic tubing are embedded in a thick concrete slab or thin concrete subfloor, which means this installation type is more expensive than a dry one. The RFH system takes more time to heat the floor and the air in the room, but the large thermal mass of concrete preserves the heating effect for several hours after the system is turned off.

2) Dry installation: A dry installation is easier to set up, less expensive and generally the most convenient type. The heating cables, mats or tubing are installed in a pocket of air under the floor, not embedded in concrete, resulting in a faster heating than a wet installation. This system configuration needs to operate at a high temperature however, since it is not embedded in the floor material.

How Flooring Materials Influence Performance

The performance of radiant floor heating is strongly influenced by the flooring material: thermally-conductive materials enhance performance, while insulating materials are detrimental. However, this does not imply you should avoid insulation – just make sure it is not installed where it can block heat transfer between the radiant floor system and indoor spaces.

Due to its high thermal conductivity and storage capacity, ceramic tile is considered the most effective covering material for radiant floor heating. Other materials such as vinyl and linoleum sheet provide too much insulation, hence reducing system efficiency. Wood floors conduct the heat quite well, but laminated wood flooring is prefered over solid wood, which can easily dry and contract.

How Do Radiant Panels Work?

Unlike radiant floor systems, these panels are generally installed in walls and ceilings, using electricity or hot water to heat aluminum sheets. Electrically-heated systems offer the convenience of preventing water leakage issues, but also have a much higher running cost due to dependence on electricity. Radiant panel systems can have a superficial construction or can be embedded in the wall, but keep in mind that future alterations are impractical in the second case.

What Are the Key Components of Radiant Floor Heating Systems?

1) PEX tubing/heating cables/heating mats: This part of the system is responsible for delivering heat. PEX tubing distributes hot water from a boiler, while the other two options produce heat directly through electrical resistance.

2) Manifold: Distributes hot water among various hydronic piping circuits.

3) Actuator valves and fittings: Valves allow water flow control, while fittings provide a connection between piping runs and other system components.

4) Control pack: Operates the system based on user settings.

5) Heating control (thermostat): Lets the user establish the required temperature.

Benefits of Radiant Floor Heating

1) RFH is suitable for new constructions with large rooms and high ceilings, improving both performance and comfort.

2) Easily-adjustable comfort levels and heating controls.

3) Energy savings and reduced bills.

4) More free space is available, by eliminating forced air systems and their associated ducts.

5) Air moves by natural convection, minimizing the spread of dust and allergens.

6) Silent operation

7) Universal control

If you are ever uncertain as to which method of radiant floor heating is most suitable for your space, consult the expertise of an HVAC engineering professional.
