Depending on the temperature setting of your thermostat, your heating system will deliver more or less hot air to the indoor spaces around your home. Our company repairs air conditioners in Tucson , and we can make sure that your HVAC system is functioning properly throughout every season of the year. To set up air conditioning or refrigeration services for your property, give us a call at The first is electric, and the second is combustion.
In most cases, electric heaters are safer and preferable to combustion heaters, especially in enclosed spaces. Electric space heaters most commonly work using either convection or infrared, so those are the two types we will focus on first. Convection heaters work by pulling air from the room over a heated surface to warm it and then pushing it back throughout the room. This is common for many popular space heaters and electric wall heaters. The unit will then turn off until the ambient temperature falls to a certain point, which triggers it to turn back on.
They work by producing infrared radiation, which offers a different type of warmth than convection. Rather than heating an entire space, these devices direct heat to bodies or objects that are directly in their path. The other category of space heaters consists of combustion-style models.
These heaters can be either vented or unvented, but both are less commonly used indoors. Most of other forms of heaters are convection heaters which primarily heat volumes of air, which then has to transfer its heat to the building in order to warm the thermal mass.
The direct transfer of heat to the building is why Herschel is more efficient and saves energy compared to convection heating. Herschel infrared panels do not heat the air and so typically only need 25 watts per m3. You may be forgiven for thinking a kilowatt of energy must possess the same heat transfer properties whether emitted by a convection or radiant heater, but this is not correct. Radiant heat has a higher rate of heat transfer per kilowatt than convection, so you need less of it.
Electric resistance, natural gas and propane systems are often the most affordable option in new construction and in homes with existing duct networks. But if you need to install a duct system in an existing home, the cost of the ductwork may be several times the cost of the heater itself. The installation and equipment costs of air heat pumps are often twice as high or higher than the costs of installing electric, gas or propane furnaces. And geothermal heat pumps are typically the most expensive to install, with installation costs dependent on the complexity of the installation of underground piping.
Ductless systems may be the cheapest option if you're only heating one room, but because you need a separate system for each heated space, the installation and equipment cost increases with the number of systems. As for operating costs, geothermal heat pumps are the most affordable, followed by air heat pumps and ductless systems. Among electric resistance, natural gas and propane systems, natural gas is typically the most affordable, but the operating costs are tied to the fluctuating costs of their energy sources: electricity, natural gas and propane.
Airflow is the lifeblood of any forced air system, and the chokepoint for that airflow is the filter. Every forced air system has a filter that must be replaced or cleaned on a certain schedule, and neglecting to perform this maintenance on time can result in higher operating costs and increased system wear.
Any system with an outdoor condenser installed at ground level this excludes geothermal heat pumps and ductless systems requires some additional DIY maintenance. The condenser should be kept free of weeds and debris and should occasionally be gently hosed off to clear away dirt. All other maintenance should be performed by a licensed HVAC professional once per year, ideally before the start of heating season. This maintenance should be performed every year, no matter how well the system is performing.
Annual maintenance extends the life of the system, optimizes energy efficiency and ensures the system's safety. In the case of all heat radiating systems, they work silently and don't buffet a room's occupants with blasts of hot air. However, they tend to work more slowly to warm up a room when compared to forced air systems. This is largely due to the fact that they rely on convection to heat the air and make it circulate through the room.
That said, some types of radiant systems work faster than others. Radiant heat can be more efficient than forced air systems with duct loss problems, and some people with allergies prefer it because the lack of air circulation doesn't stir up allergens.
However, because these systems circulate water as either steam or liquid, radiator systems can be prone to problems such as blockages and leaks. This allows cooler air on the floor to flow through the heater fins and be heated.
One drawback is that fur from shedding pets can get pulled into these kinds of heaters and block airflow. The installation costs of radiant systems tend to be even more difficult to estimate than those of forced air systems. With passive solar heating, for example, the heating elements are integral to the construction of the home and could add anywhere from a few thousand to several tens of thousands of dollars to the total cost of designing and building new construction.
With boiler-based systems, the cost of boiler installation ranges from a few thousand dollars comparable to electric, gas or propane furnaces for smaller boilers into five-figure sums for larger ones. If radiators, hydronic baseboards or floor heat piping must be installed, the cost is tied directly to the number of units or square feet of flooring. So the cost of both the boiler and the heat distribution equipment increases with the size of the home.
Similarly, the cost of electric radiant floor heat installation usually boils down to a price per square foot, so the total cost depends on the size of the home. In the typical home, the operating costs of these radiant systems tend to be lower than those of electric, gas and propane furnaces but higher than those of heat pumps.
As with installation, however, this can vary along with the size of the home. Electric radiant floor heating is expensive to operate, for example.
