What is a millivolt furnace?
What is a millivolt furnace?
A millivolt heating system is usually a floor heater or a wall heater that doesn’t use electricity; for example, a gas fireplace or a gas-powered wall heater. Millivolt systems are regulated using thermostats specifically designed for the system, commonly known as ‘millivolt thermostats’.
How does a millivolt gas control work?
Millivolt Gas Valve This type of valve makes use of a standing pilot that continuously burns to heat a device, either a thermocouple or thermopile, which then produces a small amount of electricity – less than a single volt, hence “milli”-volt.
What is the difference between millivolt and IPI?
The difference between the IPI compared to the Milivolt system is that a Milivolt has a pilot light that stays on 24/7. The IPI system does not use a pilot light and instead relies on an electronic ignition switch to light the pilot after flipping on the wall switch or using the remote.
How many millivolts does a good thermopile produce?
A healthy thermopile in an open circuit test will read between 650 to 850 millivolts or somewhere in between. If the open-circuit test reads below 400 millivolts, then the thermopile likely requires service or replacement.
What is millivolt ignition on gas logs?
Millivolt ignition systems use a standing pilot light. This type of ignition system does not require any external power. The pilot light can be turned off for extended periods of non-use and them re-ignited when needed. Millivolt are the most common ignition type on the market.
Does ecobee work with millivolt systems?
Unfortunately, the Ecobee (and Nest and most other competitors as well I believe) don’t support millivolt heaters natively. They only support the HVAC wiring system. Millivolt does not contain wiring for power, so that has to be managed as well.
What is a millivolt gas fireplace?
What is an IPI system?
Intermittent Pilot Ignition is an electronic system, which uses an electrode to ignite the pilot gas. When the main burner is off the pilot is also off. The IPI system ensures the pilot flame extends over the burner for immediate ignition and secondly conserves energy when the appliance is not in operation.
What is the function of a closed millivolt test?
CLOSED CIRCUIT – This measures the millivolts used by the coil in the electromagnet. A rule-of-thumb is this reading should be roughly half of the open circuit. It is taken using an adapter screwed into the magnet and the thermocouple screwed into the adapter.
What does millivolt control mean?
Millivolt ignition systems use a standing pilot light. This type of ignition system does not require any external power. Millivolt ignitions are also remote ready and can accommodate anything from a simple on/off wall switch to a programable thermostatic remote.
What is the best gas furnace?

How does a millivolt thermostat work?
A millivolt thermostat works with a standing pilot gas valve system. Several thermocoulpes in series generate a voltage while sitting in a pilot flame. It works like the thermocoulpe in some stoves work to prove a fire is established. They usually make .75 volts.
What is millivolt fireplace?
The most common type of gas fireplace uses a millivolt ignition system. The piezo ignitor is usually connected to a button that generates a spark when depressed.
What is an LP Furnace?
Propane Furnaces – Fixed LP Gas Heating Systems. Homes and buildings equipped with central heating systems or fixed furnaces are uniquely fitted to the building or home being serviced. Furnaces are designed by HVAC mechanical engineers and are installed by licensed air conditioning and heating contractors according to manufacturers specifications.
