During summer months, the air conditioning system will use the same floor vent outlets to pump cool air into the living space. In all areas with moderate to severe winters, the vents will be in the floor (because heat rises!). They are either in the floor (favoring heat) or in the ceiling (favoring A/C). Typically before installing a forced air system, a decision is made in the early going to favor either heating or air conditioning with the installation of the air vent outlets.
The reason is due to efficiency warm air rises, and cold air falls.
#STEAM RADIANT HEATING SYSTEM INSTALL#
Yes, it generally cost less to install a typical HVAC air system when building a new home, but it may end up costing more in the long run. Well, the answer, once again, is “it depends”. At first glance, it would seem to make sense to have both heating and air conditioning delivered to the interior by the same ducts. One of the primary reasons that forced air systems are generally considered as a default choice of new constructions stems from the use of air conditioning in summer months. Therefore, the radiator warms the air, people, and items in the home through radiation, regardless of direction. Even though the air that’s being heated through conduction is rising, you can still feel heat from the bottom side of the mug. Now place your other hand several inches below the mug. What about radiation? Radiation warms everything within the space regardless of air. This air, because it’s warmer than the surrounding air, tends to rise. It is conducting energy (heat) to the air. The radiator warms the air it comes in contact with through conduction. Take the example of wall-hung radiator panel. Radiators and radiant floor systems heat a space via two means: conduction and radiation. Because of this mass, and the fact that water is a much better conductor of energy than air, cold spots within a home are far less of a factor with a properly designed hydronic system than with forced air. That may be a radiator of some type, or warm floors. Hydronic systems, on the other hand, heat the space via “warm mass”. As a result, the overall heating performance of your furnace or heat pump in your newly built “dream home” might be suboptimal. Air movement in the home can also stir up and distribute allergens, such as pet dander.
#STEAM RADIANT HEATING SYSTEM SKIN#
Forced air systems also dry out the indoor air and are one reason a lot of people struggle with dry skin or chapped lips in the winter. Excessive noise from blowers, dampers, and vent outlet plates may also be noticeable as well.
Effectively controlling air flow from a furnace to balance the cold/warm spots in a home is very difficult and rather imprecise. Frequently, cold and/or warmer spots can be noticed in homes with this kind of heating system. Even though the air blowing into the living spaces is warm, it doesn’t completely heat the living space. Air is drawn from the home through return ducts, heated by the HVAC equipment, and sent back into the living space through supply ductwork. If you’ve lived in a home with forced air heat (like a furnace or heat pump), you are probably familiar with air movement.
One big comfort advantage that most hydronic systems offer is that they don’t require the re-circulation of air within the home. These systems are generally considered to the premium choice and offer the most flexibility in terms of heating options, and the ability to tie domestic hot water production into the same system. Without diving into the many details of each system type, your choices are, for the most part, as follows: electric baseboard, forced air systems (furnace or heat pump), and hydronic heating systems (fin tube baseboard, radiators, and/or radiant in-floor systems).Īs a reminder, hydronic systems use hot water from a boiler to heat your home. How important is comfort and energy efficiency? Is resale price of this home important to me? What is the upfront cost? What kind of flooring will be used throughout the home? How long and cold are the winters in my area? Do I want to install a snowmelt system? These are likely things you have discussed with your general contractor. It depends on things that you’ve already taken into consideration while determining what your new home will be. So what is the best heating system for new home construction? What are the most efficient options? There are plenty of factors involved, so as with many big decisions, the answer is “it depends.” New construction gives you a unique opportunity to install the perfect home comfort system for your lifestyle and locale. However, you may not have taken the HVAC equipment for your dream home into consideration. Building a new house gives you the chance to build the home of your dreams.
