This is a diagram of a complete furnace with outdoor unit system, including additional components that do not come standard.


A thermostat is a device that regulates the temperature of a home at a desired setpoint. An added feature is a programmable thermostat which can be programmed for different temperatures throughout the day. An example would be programming the thermostat to reduce heat from 8:00 to 4:00 when the home owner is at work. This can help save in gas or electricity.

2)Air Conditioning Unit

An air conditioner is an appliance used to extract heat from an area using a refrigerant. With the high efficiency Ruud air conditioning unit a home owner can save money on cooling.

3)Heat Pump

A heat pump is a reversible outdoor system that allows the home owner to heat their house in the winter and cool their house in the summer. Heat pumps are equipped with a reversing valve and optimized heat exchanger to allow the machine to draw heat out of the air for heating a home.


A furnace is a device used to heat your home. The Ruud high efficiency line of furnaces can save homeowners money on their heating bill.

5)Cased Coil

The case coil allows for the air conditioning unit or the heat pump unit to transfer its heating and cooling options into the house. The furnace blows air through the coils on the case coil which are filled with freon allowing for heating or cooling to take place depending on the unit used.

6)Plenum Heater

A plenum heater used in conjunction with a heat pump unit can heat the whole house in a very efficient and compatible system. The plenum heater is a heating system that uses electrical currents to heat coils which in turn heat your home.


A humidifier increases the humidity (moisture) levels in the house in the winter causing the air to seem warmer, thus saving the home owner money on heating bills.

8)Furnace Filter

The furnace filter purifies the air flowing through the system of the household. This allows the home owner to have cleaner air to breathe.

9)Supply Air Duct/Return Air Duct

The supply air duct and the return air duct supply and return the air flowing through the system.

10)Heat Recovery Ventilator (HRV)

HRV's are fresh air exchange appliances. They take fresh air from the outside and supply it to the house. It in turn takes the stale air out of the house and controls the humidity levels to minimize heat loss.

11)Boiler System

The boiler system allows home owners the ability to heat water for radiant in-floor heating systems. The comicor water heater can be used to heat the radiant in-floor and the domestic water for the house.

Subflooring Attachments Poured Concrete Floor

1)Floor Joist

Floor joists support the secondary floor from collapsing in and provide a great backer for the subflooring.


Subflooring is a floor that goes over the floor joist. This subfloor is an excellent source to staple the tubing to.

2)Hepex Tubing

Hepex tubing is the tubing used to run the radiant in-floor heating system. The water mixture runs through these tubes to heat the floor and the house.


Foam allows for the radiant in-floor heat to be transferred to the surface instead of being lost into the ground.


The sealant seals the wood to help the heat radiate up to the surface to keep your feet warm.

6)Concrete/light weight gypsumcrete

This substance covers the tubing and provides a solid base on the main level and the secondary levels.


Adhesives are used to glue the flooring to the concrete or light weight gypsumcrete.

8)Finished Floor

This is the finished product after everything is done with the in-floor heat.


Rebar is an excellent source to tie the hepex tubing down so it does not float up through the concrete.
