The grid heater is between the intake elbow and the intake manifold. It's just a big resistor that heats up when current is applied across it and thus heats the incoming air charge until cylinder and engine temps get up to operating temperature.
What is the purpose of the heater grid?
The purpose of the heater grid is exactly the same as that of glow plugs - to warm the incoming air charge during cold starts.
How does a grid heater relay work?
There are 2 grid heater relays, one for each grid heater. Each are ran by the ECM individually. The green wire on each of them is ground. The yellow and red wires are for each unique relay and serve as the positive lead that goes to the ECM. Upon being sent positive voltage, the relay energizes and the grid heater turns on.
Why does the grid heater cycle on and off?
Typically this occurs when temperatures are below 55-65*F. You'll notice that the battery voltage will fall slightly more than normal during this time that the WAIT TO START light is lit. Once started the grid heater will continue to cycle on and off to maintain proper manifold temperature. There are 2 grid heater elements.
How does an electric heater work?
The next step in the heating process depends on whether or not the heater has a built-in electric fan or not. If there is a fan, it will help draw cold air into the heater. The air passes over the heating elements and then is pushed out into the room — this is similar to how hair dryers work.

Why do Cummins not have glow plugs?
Cummins engines do not have glow plugs. Instead of glow plugs, Cummins engines are equipped with a single heater grid as their heat aid. These grids are more reliable and work by heating all the heat coming into the air intake. Both the 5.9L and 6.7L Cummins engines come with a grid heat system.22 Jul 2021
When did Cummins start using grid heaters?
Since the first Cummins-powered Ram truck was produced in 1989, Cummins uses a grid heater, not a set of glow plugs, to heat the intake air. Diesels need a cold-start aid, while gas engines don't. Gas engines use a spark to ignite a highly flammable mixture of gasoline and air.26 Feb 2013
What does a grid heater do on a 6.7 Cummins?
Your Cummins diesel engines have an air heating grid located on the intake manifold. The heater grid is used to raise the incoming air charge as the air passes over the grid. This heated air charge aids in the ignition of the diesel fuel-air mixture.
Will a Cummins start without a grid heater?
yes it does get hot, but it will not heat the air once its moving. it will slightly increase the air temp before you start.7 Dec 2008

The yellow and red wires are for each unique relay and serve as the positive lead that goes to the ECM. Upon being sent positive voltage, the relay energizes and the grid heater turns on.
How does a fan work in a heater?
If there is a fan, it will help draw cold air into the heater . The air passes over the heating elements and then is pushed out into the room — this is similar to how hair dryers work. This is also known as convection heating because the warmth is transferred through the air.
How does electrical energy turn into heat?
Electrical energy is turned into heat as the current passes through the resistor. That’s why electric heaters are also known as resistance heating units. The next step in the heating process depends on whether or not the heater has a built-in electric fan or not.
What Are the Most Popular Heaters?
Several different types of heaters are popular with consumers who want to save money and energy heating their homes. Here are five favorites:
What Are the Benefits of Portable Heaters Over a Central Heating System?
There are several benefits should you choose to use a portable heater instead of an expensive central heating system.
How do portable heaters save money?
There are three main ways that portable heaters will save you money: 1 You will consume only as much energy as is needed to heat the spaces in your home that are being used. During the day, if most of the family is at school or work, just turn the space heaters off or down. Use a portable heater to warm the spots where people are working, cooking or watching TV and let the heat follow you around the house. 2 Portable heaters do not require any installation. Some units can be wall-mounted, but all can be easily moved and stored when the weather warms up. This saves you money on installation costs. 3 Portable heater maintenance is an easy DIY affair. Simply follow the guidelines set out in the user manual and keep the unit clean. There is no need for expensive service calls and regular professional maintenance tasks as there is with a heat pump or steam radiator system.
Why are portable heaters better than infrared heaters?
Portable heaters allow you to heat only the areas that you need to keep warm, so you use less energy overall. Almost no energy is wasted converting electricity to heat so you get the best use of the energy you pay for. They also help reduce demand for high-polluting petroleum products like oil and natural gas — especially if you choose green electricity providers. Infrared heaters are one of the most popular choices for those who are environmentally conscious.
Why are infrared heaters safe?
Infrared Heaters: These are some of the safest heaters to use because infrared radiation is environmentally friendly and energy efficient.
How exactly does a heat pump work?
When it comes to heating, think of a heat pump as a refrigerator working in reverse – instead of keeping your veg and dairy products cool, it’s warming your home using a refrigerant, which can evaporate into gas and condense into liquid.
How does gas heat?
The gas (now heated) is passed over the internal heat exchange surface. This heat can then be either blown around the interior or transferred into a central heating or hot water system. The gas falls in temperature as the heat is transferred into the home and it subsequently returns to a liquid state.
What is the pump in a central heating system?
The pump performs the same role as a boiler in a central heating system. But it uses ambient heat from the ground, rather than burning fuel to generate heat.
What is an air source heat pump?
An air-source heat pump takes heat from the air and boosts it to a higher temperature using a heat pump. There are two main types of air-source heat pumps – air-to-water and air-to-air. Air-to-water heat pumps take heat from the outside air and feed it into your wet central heating system (similar to existing gas central heating).
Why is it important to have a heat pump installed in a house?
As the ground and air outside always contain some warmth, a heat pump can supply heat to a house even when it’s cold. It’s important that good energy efficiency is installed in homes so that heat pumps can work at their best.
How many homes in England use heat pumps?
According to the government’s Energy White Paper, fewer than one per cent of homes in England currently use a heat pump. So clearly the pace of change and scale needs to pick up in this home energy transformation. There is no ‘silver bullet’ for home heating, as different low-carbon heating solutions may be required for different types of buildings and locations. Heat pumps are expected to make an important contribution to decarbonising heat.
What is a heat pump?
Heat pump systems are designed to efficiently extract a greater amount of heat energy from the surrounding environment than the energy they consume to create heat.
How do Grid-Tied Inverters Work?
Fossil fuels damage the environment with weapons like global warming and greenhouse effects . The increased demand for energy sources has significantly expanded the reliability of renewable resources.
How long-lasting are Grid-Tied Inverters?
An unlimited supply of clean energy with grid-tied solar energy systems can be known for their techno-driven and bidirectional features. Inverters are an essential part of the whole system, and daily production and consumption of power can differ according to weather and usage.
How do storage heaters work?
Storage heaters use off-peak energy to store heat. How do they do that? By warming internal ceramic bricks during the night, when there’s less pressure on the National Grid. And then voila, heat is gradually released throughout the following day.
Where is the control on a storage heater?
You’ll usually find your storage heater controls on the top of the heater itself . Once you’ve found the perfect heat setting, you shouldn’t need to fiddle much with the controls unless there’s a cold snap!
Are storage heaters right for my home?
Storage heaters used to be thought of as a plan B if you weren’t connected to the mains gas supply. But times have changed, and modern storage heaters are being favoured even if there is access to the mains. So find out if storage heaters could be the right choice for your home with this quick summary:
Why do storage heaters charge at night?
Not only that, but storage heaters help fight the climate crisis. They don’t charge up during the day, when there’s higher demand for carbon-heavy gas-powered electricity on the grid. Instead, by charging at night when the grid is more likely to be powered by renewables, storage heaters are a lower-carbon form of heating – helping to support a greener, more flexible grid.
What is a dimplex heater?
Dimplex’s Quantum storage heaters are some of the most advanced and economical around. You can programme them with daily and weekly schedules and set the room temperature. And for the tech fans out there, an iQ controller monitors the room and learns your heating habits! They also have a fan, a thermostat, a child-lock and a boost function to give you instant heat when you need it.
What are the drawbacks of a storage heater?
There’s lots to get excited about when it comes to storage heaters – but it’s not all sunshine and roses. There are one or two other things to consider before you decide that they’re right for you. Here’s our rundown of the main drawbacks: 1 Storage heaters use electricity, which can be more expensive than gas 2 With some of the more basic models, excess stored heat can sometimes make a room actually feel a little too warm (if there is such a thing over winter!) 3 Much of the stored heat can sometimes be used up by the evening – which is often the exact time you want to crank up the temperature!
