What Temperature Should I Set My Programmable Thermostat To - 4) Please confirm this advice if you would; it is better to have your thermostat left at 70°F. to 72°F. during the day while your home is empty and adjusts accordingly when you get home as opposed to shutting off the heater/ac and turning it on when you get home. I would think this would put less strain on the unit. Thanks in advance for your help. (more…)
Hot Water Unit Heater Protecting Mechanical Room - Unit heaters are used in various places to protect equipment and provide comfort to occupants. This hot water unit heater provides protection for a mechanical room where there is a large air handler and other associated equipment in the mechanical room. This system is controlled by DDC. A thermostat on the wall detects the temperature of the mechanical room. (more…)
Tankless Water Heater
All About Hot Water Heaters - I have been transformed into a believer in tankless water heater systems. A few years back, I moved to Ukraine for professional reasons. When I first arrived in Ukraine it took a while for me to adapt to the culture, language, services, and way they do things here. Power failures, water outages, and occasionally natural gas outages are quite frequent here although it is tolerable and a minor inconvenience. (more…)
Infrared Heating System
Infrared Radiant Heating systems provide comfortable heat in larger areas and spaces such as garages, warehouses, and other open spaces where other types of heating systems are not practical or efficient. Infrared radiant heat works through thermal radiation transmitting heat to large objects including floors and walls.
These large objects heat up through thermal radiation and then release that heat to the surrounding air through convection making the open space or open area comfortable for the occupants. (more…)
HVAC Reznor Heating System – this Reznor unit heater provides heating for warehouses, garages, and other open spaces which can be heated with unit heaters. Unit heaters are ideal for big open areas which need heating without ductwork being used to channel the air into the open space. (more…)
Air Handling Unit Components 2: Heat - There are many different types and arrangements of heating systems for air handling units and these types of heating systems and arrangements of heating systems vary from commercial to residential. Some air handling units do not have any heat source inside them at all but have remote heat for zoning. The air handling unit provides the airflow and the remote heaters provide heat for zoning.
Sometimes the air handling unit is a VAV air handling unit and other times it is just to provide air for a duct heater whether the duct heater is gas-fired or electric. For air handling units which some have heating systems inside the five main ways of providing heat for air handling units are:
HVAC Definitions - In air conditioning and heating the name HVAC is often used. HVAC stands for heating, ventilation, and air conditioning. Other acronyms are less used to describe air conditioning and heating applications is HVACR or heating, ventilation, air conditioning, and refrigeration and HACR or heating, air conditioning, and refrigeration.

Geothermal heat pumps use groundwater or water circulated through pipes to exchange heat with the earth. Geothermal versus air-source heat pump systems use the earth’s natural temperature to exchange heat and provide heating and cooling. The temperature of the air varies widely with the weather. Whereas the temperature of the earth is nearly constant.
This makes the use of a geothermal system ideal for heating and cooling. It also costs less in energy use because of the constant earth temperature versus the widely varying temperature of the outside air. Consequently, geothermal systems make sense and can save lots of money in energy use.
