The difference between heat and temperature

The difference between heat and temperature

How much do we really understand the difference between heat and temperature and how it is conducted?

If we think of a cup of hot tea, when we hold onto the cup it feels warm to the touch. Heat moves from the cup to my hand, showing us that warm things will heat cold things by the transfer of heat or heat energy.

So to explain, the cup of tea was hot in comparison to my hand. When I held the cup the molecules in my hand moved faster as heat energy flowed from the mug to my hand. As a result the mug had then less heat energy as this had been transferred to the colder item (my hand) and the molecules within the cup begins to move slower and will continue to decrease in temperature until the mug reaches the temperature of the room.

Two cold items can actually heat one another if you were to rub the two together. Heat is not a calorific object but a form of energy created by the movement of molecules in any object.

How do we measure the amount of heat energy that an object has?

Temperature is the measure of how much heat energy an object has.

These 3 statements are all correct

  1. The mug of tea has a higher temperature than my hand
  2. The molecules in the mug of tea are moving faster than the molecules in my hand
  3. Heat energy will flow in the direction from the tea to my hand (not vice versa)

Heat can be transferred in one of 3 forms:

  • Conduction
  • Convection
  • Radiation

Heat conduction or thermal conduction is the process where heat is transferred within a body due to the collision of neighbouring particles. For example:

A child that has been out in the snow all day, comes into the house and cuddles up to his mother to keep warm. This is because the heat is transferred from the mothers’ body to his body using conduction.

Heat convection occurs when heat is transferred through a liquid or gas by the hotter material moving into a cooler area

Boiling water is a great example of everyday convection. Heat passes from the burner into the pot, heating the water from the bottom. The hot water then rises and the cooler water moves down to replace it causing a circular motion.


The term radiation refers to energy that travels through space or matter in the form of energetic waves or particles (called infrared light). When radiation occurs, waves move out in all directions from the producer of the energy.

For example when you park your car when you arrive at work on a sunny day with no shade, the car will heat up throughout the day as the energy from the sun is transferred to the car which is held by the vehicle and released throughout the day, making the car extremelywarm when you enter it. 

We can use all of these forms of heat transfer to warm us, when we are cold. In a work environment you conduction would not really be used as a good form would be to use a hot water bottle.

Convection is often used in warehouse heating and factory heating in the form of industrial warm air heaters. Warm air heating works by pulling the cold air within the building and pushing it over the heat exchanger where the cold air is heated and then pushed out via a fan into the building, where the air is distributed around the building until the room reaches the required temperature.

Radiation is often used when considering garden centre heating using infrared radiant heaters. These work by heating the objects in the room, rather than the air and releasing the heat energy during the day, helping to maintain a comfortable temperature for the employees, customers and a perfect environment for plant growth.

Heaters Wholesale specialise in providing high quality industrial heating solutions across the U.K. Including warm air heating for your factory, or radiant heaters for your garden centre.

How Radiant Differs Between Other Traditional Heating Methods.

How Radiant Differs Between Other Traditional Heating Methods.

Ever since the onset of the industrial revolution and the beginning of manufacturing, factory buildings and warehouses’ struggled to retain the heat within the premises. Since the development of the of the most basic heating technology, the industrial heating market has evolved and grown from strength to strength.

The case in point is how popular infrared radiant heating has become throughout the years, compared to the traditional Warm Air Heating. They both hold their own attributes, but, depending on the building, Infrared Heating can represent the most effective heating solution, for factory and  warehouse heating.

Many factory premises were built many years ago and although structurally resilient, there was little concern over heat loss as there  was no major thought into energy savings like today.

For example, the high ceilings that you often see in many industrial premises tend to lead  to a process  called stratification. This is where the air in the room arranges itself into layers of temperatures, ascending from cold air at the ground level to warmer air towards the ceiling of the building.

By contrast, infrared radiant heaters work like the sun which transmits infrared rays into the room, which is then absorbed by the objects and people within the building. This heat is then slowly released over  time allowing the room to remain at a comfortable temperature throughout the day. This can reduce the likelihood of stratification, meaning less heat loss through the roof and a potential saving on your  energy use.

Will Infrared heating suit my building.

Each property will differ, with many factors that can identify whether radiant heaters are the right choice for you. Look around your property do any of  the below apply?

Do you have high ceilings?

Do you regularly use loading bays with open shutters that increase the escape of the warm air.

Are your energy bills excessive?

If you answered yes to any of the above then you may benefit from the installation of radiant tube heaters, and may benefit from a site survey carried out by a fully qualified installer to assess the most efficient way to heat your premises.

Warm Air Heating Vs Radiant Heating

Warm Air Heating Vs Radiant Heating

When you’re investing in a brand new heating system for your Commercial or industrial environment, you want to get it right. But with new types of system regularly coming on the market, it can be a little confusing for a heating novice. Luckily, Heaters Wholesale are here to explain. We specialise in two new types of heating system – radiant heating and warm air heating. Both are versatile, efficient products, and which one you choose will probably depend more on your working environment than anything else. Here are a few tips to help you.

Warm Air Heating
Warm Air Heating systems – often referred to as HVAC – work by heating air and pushing it around a building. These heating systems have the added bonus of being suitable to also use as air conditioning in the summer months, by simply adjusting the temperature of the air. Because of this they can be ideal in workplaces which are heavily populated, such as offices, hotels and restaurants. They allow you to save on your energy bills too, costing around 20% less in energy than a traditional heating system.

Radiant Heating
These clever systems work by radiating heat around the room, hitting people, objects, walls and floors which then retain the heat and then act as additional heaters. This brings the benefit that even if the windows or doors have to be opened and cold air rushes into the building, the various objects, walls and floors will still retain their heat, and much less heat will be lost than with a traditional system. This benefit in turn leads to large energy savings too. So, radiant heaters can be ideal in businesses where it is necessary to regularly open doors, such as some factories. An added benefit of Radiant Heating is that they also help reduce the risk of plant disease, making them ideal for greenhouses and garden centre heating too.

An introduction to warm air heating

An introduction to warm air heating

With an increasing amount of economic and environmental pressure being exerted on businesses to both save money and energy, more and more companies are looking for increasingly innovative ways of reducing their electricity and heating bills. We at Heaters Wholesale we can supply a range of commercial warm air heating systems which are a modern and more efficient alternative to traditional water heating systems.

Some of our systems are capable of saving you up to 20% on your business’ energy consumption, so you can view the expenditure on your new heating system as an intelligent, long-term business decision.

So what is Warm Air Heating?

A replacement for the traditional water heating systems, warm air heating is now a popular choice for new installations, particularly thanks to their ability to improve a building’s energy efficiency.

They are a popular choice when considering Factory Heating and Warehouse Heating.

Warm air heaters work by forcing warm air around a building and some of the systems we can supply are able to save up to 20% on energy bills.

Floor Standing:

If you have space within the corner of your property, which is going unused, why not fit one of our floor standing heaters, such as the “cabinet heater”.
