How Do Central Heating System Work

How Do Central Heating System Work?

Having a central heating system feels like a blessing in those chilly winter nights!

Keeping home warm and toasty is quintessential for Brits and all thanks those warming ducts that turn our home cozy and lively.

Working of central heating system depends on fuels and heat distribution patterns.

Going for a new build or home renovation? Understand how different types of central heating systems work, installation factors and cost associated with each.

What is a Central Heating System? 

Central heating simply means that your home is heated from a central location.

The heating system is spread throughout your home via pipes or ducts.

A heat pump moves the heated water (or heated air) through the pipes to the central heating radiators and then, finally back to the source for reheating.

The heat circulating in your home, usually through connecting pipes (ducts) from the heating system, is adjusted via thermometers, radiator valves, or time controller, known as a Central Heating System.

How Does Your Central Heating Works?

It’s very important to understand energy to make more on energy savings.

There are primarily two types of central heating systems: Forced air systems and Radiant Systems.

Let’s have a look at what principles these systems work.

1. Forced air Systems 

In a forced air central heating system, air is pushed into the system using a fan or a blower and is them heated.

This system comprises of a blower, air return & supply ductwork, heating unit with heat exchangers. All these are housed inside an air handler cabinet.

The supply ductwork carried air to the room while the return ductwork brings back the air from the rooms to the blower.

2. Radiant Systems

These system works on the principle of convection.

The heated air tends to rise up and is replaced by cooler air and so on.

These are a bit less popular than forced air system and they warm the room less quickly but are inexpensive to install, buy and maintain.

Now, let’s check three main types of central heating system that area popular in UK.

Based on above mentioned principles, get insights into how these systems actually work.

3. Furnaces 

Furnaces work on the operational principles of forced-air systems to distribute the heat.

Depending on the fuel such as propane, heating oil, natural gas or electricity, furnaces are used to warm-up the homes.

The blower inside the furnace is used to push the heated air generated by burning the fuel through the ducts and reached various parts of the home.

Return ducts are used to carry the cooled air back to the furnace for reheating.

By adding a heat pump or air conditioner, the electric central heating system can offer you dual benefit by cooling your home in summers.

4. Boilers

A boiler is very energy-efficient and can use a wide range of fuels to generate heat such as natural gas, propane, electricity etc.

Pipes connected to a heating source are used to transmit heat around the home either via radiators or underfloor heating.

There are four parts to this forced-air type central heating system: a boiler, pump, pipes, and radiators.

The boiler heats up the water and a pump transports the heated water from your boiler to your radiator or underfloor heating via pipes and returns the water back to the boiler to be heated again.

5. Heat pump central heating

Heat pump central heating system actually moves the heat rather than generating them which turns them more efficient than other systems.

During winters, they work by gathering the outside heat and discharging it inside through ductwork.

The process reverses during the summer season.

There are two types of heat pumps:

  • Air source heat pump: They work by gathering heat from outside and releasing inside.
  • Geothermal or Ground-source: The warmth from ground is pulled and sent inside the room.

How is Central Heating Controlled?

The central heating can easily be controlled and maintained to ideal temperatures using a thermostat or radiator values.

A smart or standard thermostat helps in monitoring the room temperature and switches off the heating system when it has reached a specific set limit.

Additionally, some boilers do come with timers that help you turn off the timer after a specified limit.

Going for a mart thermostat empowers you to control your home warming from your mobile device and make it available with you 24/7.

Central Heating Installation

Your home’s central heating system plays a very vital role in keeping your family warm all the year long.

It’s imperative to have high-quality components and equipments of a central heating system but having a professional installation is equally important.

Going for professional central heating installation ensures that everything is up to specification and mitigates the risk of any system breakdown or inefficient process.

The best time to install a system is when you are building your home from scratch renovating else you may end up in costly repairs and paying high heating bills.

How Much Does Central Heating Cost?

The price of depends on a lot of factors that includes specifications, components, labor cost and sometimes transportation cost.

The cost may also include the installation of boilers, style and size of radiators, pipeworks (ductworks) or sometimes additional heating controls.

The prices greatly vary as per your choice of system as well such as furnace, boiler etc and the sophistication of controls.

Underfloor Heating

How Efficient is Underfloor Heating?

Underfloor heating is a fast-rising trend for homes in the UK primarily because of its comfort and the low cost of running that it offers. The best way to describe underfloor heating is a giant radiator under your floor without the cons of a radiator. It is a stylish way to heat up the home without disrupting the interior décor.  

When prospects ask how efficient underfloor heating is, they are trying to compare it with a radiator. So in this answer, we will compare both under three headers; heat distribution, cost of running, and health.

Heat Distribution 

Underfloor Heating provides heat from the ground up, leaving a room evenly warm, totally different from radiators. The heated air rises to the ceiling for radiators, and once the air is cool, it begins to fall to the ground, leaving “cold and hot” spots everywhere. In most cases, the air around the radiator is usually scorching, but it doesn’t spread evenly around the room. 

Running Cost 

The time it takes to heat up different parts of a room means that you spend more money on electricity bills. But more than that, the heat produced by radiators causes the air to feel stuffy, and you may need to open the windows to breathe in proper air because of the reduced oxygen levels.

When you do so, you let out the heat and have to reheat the room repeatedly, costing you more. Underfloor heating maintains the room’s natural humidity, making it cost-effective to run and provides premium comfort. 


Radiators circulate airborne allergens, which means you risk having an asthma attack or other breathing allergies, which is not the case for underfloor heating. 

Types of Underfloor Heating

There are basically two types of underfloor heating; water-based and electric-based.

The water-based (wet underfloor heating) is more expensive to install than the electric counterpart but much cheaper to run. 

Other Benefits of Underfloor Heating 

  • Carbon footprint reduction 
  • Zoning – you can choose which room to heat up 
  • Provides a high level of comfort 
  • It completely eliminates dust mites

How to Choose The Best Heating And Air Conditioning System

Choosing the best heating air condition system is one of the essential additions you can make to your home.

Everything counts well!

And even HVAC is a significant contributing factor in making a comfortable environment at home.

Yes, you heard that right!

An efficient HVAC system offers a welcoming and comfortable environment where you can work, enjoy and even relax!

But which one can be perfect for your home’s space is challenging to identify.

And gathering all the appropriate information concerning HVAC systems can be intimidating.

But not anymore.

Here is all you need to know before choosing one.

Factors to be considered before choosing an HVAC System

Temperature and air quality

You must always consider how diversified cooling and heating units influence energy consumption, air quality, and indoor temperature.

For instance,

Do you know that selecting elements like UV light in the hv ac system can enhance the EPA indoor air quality score?

Well, yes!

Probably you don’t know, but these things do count.


Your heating and cooling system must effectively heat and cool the space.

Generally, the HVAC systems capacity is measured by British Thermal Units (BTUs).

Higher the BTU rate, the greater the capacity!


The heating and cooling systems have improved over the years.

Therefore, there are rating systems that identify efficiency.

Do not forget to take a look at the system ratings like SEER, AFUE, EER, and HSPF.

Maintenance Requirements

HVAC systems require regular maintenance to deliver optimal performance.

So it is always good to choose a low maintenance and cost-effective system.

Programmable Thermostat Compatibility

While choosing an HVAC, make sure that the system you select for your home is compatible with a modern programmable thermostat.

This facilitates you to manage the cooling and heating virtually.


Depending upon the space where HVAC is installed and the type you have selected, an HVAC sound can be identified.

An HVAC can be pretty noisy.

So you must choose the best fit according to the space.

If required, take experts’ help to decide one.


The ultimate goal is to provide a comfortable temperature for the home space.

Obviously, here competitive rules don’t fit.

But yes, you can at least acquire the one that fits your space, requirements, and pockets too!

PS: Expert advice might help you choose the best one.

Why is it necessary to have an HVAC System at home?

Air conditioning system

As the temperature starts to climb or fall down outside, it pretty much makes sense to choose a system that can at least maintain a balanced atmosphere within the home.

If you live in an area with high humidity or a freezing environment, you will probably understand the necessity of choosing an efficient HVAC System.

And this goes without saying that everyone understands the requirement of having an HVAC System installed.

However, choosing the best fit for your home is what matters.

Types of HVAC Systems

There are four main types of Heating, Ventilation, and Air Condition Systems. However, you must choose the one that is the best fit for your home or space.

The main HVAC Systems types include:

Heating and Cooling Split System AC

This is the most common type of HVAC system.

As the name of this type suggests, it is a split of two discrete units in which

One serves the heating purpose

While another is for cooling.

Such systems come with outdoor and indoor units.

These are equipped with a cooling system placed outside that utilises refrigerants, coils, and compressors to cool air.

In contrast, the heater in such products is placed in the basement that utilises the gas to warm up the house.

However, a traditional thermostat is often utilised to control the temperature and keep it at a comfortable level.

Hybrid Split System

The hybrid split home ac system includes identical features to the split one but has some fundamental differences.

This system includes a hybrid heating unit that is counted as one of the unique features of this type that facilitates lowering the energy cost.

Such a system has a capacity to switch the gas power that is faster, efficient, and quiet.

Mini-split duct-free system

A mini-split duct-free HVAC system comes with an enormous upfront cost and a list of advantages for specific requirements and applications.

Such systems offer a fantastic solution for spaces where traditional ducted systems are unsuitable.

It is installed directly in the specific areas where cooling and heating are required offering better independent control.

Packaged Heating and air conditioning system

A packaged heating system and ac system comprises everything that includes a condenser, evaporator, and compressor in a single unit.

It efficiently fulfils the heating and cooling requirements of the house.

It has a compact size, making it an efficient option for home spaces with a space crunch.

It’s an easy to maintain and efficient choice.

How to choose the right HVAC system for your home?

 Factors to consider while choosing HVAC system

Choosing the right HVAC System depends upon the various factors that you must consider a few essentials.

Unit type

You may find ample options while choosing one for your space.

Central, split, ductless mini-split systems or any other.

This actually depends upon the space you have and which can fit the best within it.

Unit Size

The size is an imperative factor to be considered.

Choosing the right size for your space can considerably limit the options from a wide variety to a few.

This can help make the decision easier.

Measure the dimensions of the space you want to install the HVAC System and explore the options that best fit the space.

Energy Efficiency

The energy efficiency of an HVAC System depends upon the location you live in.

For instance, if you live in a hot area, choosing the higher energy efficiency can be perfect for you.

However, choosing out of various options like seasonal energy efficiency ratio or others can help segregate the right choices.

Design and Specifications

You can consider the best features for the HVAC Systems based on the size of the space.

But yes, before choosing an HVAC unit for your space, check out whether

The space of your home includes a centralised ductwork

Or if your home area has enough space for both outdoor and indoor components.

It will help you make the choices more specific to the requirements.

Maintenance Requirements

An HVAC unit might require annual tune-ups.

This may include replacing air filters and cleaning the outdoor and indoor components.

Getting an efficient HVAC System requiring low maintenance and cost-effectiveness can be the feasible choice.

Available Features

Apart from the cooling effects of the HVAC System, one can also choose to have some accessibility features that make it easier to use.

A smart accessibility system enables you to monitor the unit from your phone.

However, to maintain energy efficiency, you can also upgrade the thermostat, which permits maintaining a temperature schedule.

Common Mistakes when buying an HVAC system.

While looking for the HVAC Unit, people often make a few common mistakes.

However, making a note of these errors and avoiding making such mistakes while choosing the HVAC unit for your space can help you get hold of the best.

  • Buying the wrong size and then adjusting later.
  • Going with one estimate only
  • Choosing one with inappropriate knowledge
  • Only looking at the pricing

Not only this, but several other considerations can also impact the choice.

However, choosing a reliable partner to help you select the best fit for your space can always be beneficial.

How much does an HVAC System cost?

The cost to select and install a new HVAC system depends upon various factors, including:

  • The size of the unit
  • The home location or space
  • Based on the space and installation ability within the area, you may expect to pay a higher cost for the HVAC Unit components.
  • The Brands
  • The brand you opt for may also affect the cost of the HVAC System.
  • The complexity
  • The cost can also depend upon the severity of the space.
  • The structure of the unit, size, and other essentials can contribute to deciding the cost of the installation.

Why is it essential to have the right-sized HVAC System?

Since you know that understanding the equipment type and their efficiency ratings, one can choose the right sized equipment for the home.

One of the most common mistakes that people make while choosing the HVAC unit for the home is that they tend to get a larger system than what they require.

This may lead to multiple issues.

Consider this statement first,

A cooling unit that is larger than required will cool down the temperature of the home quickly.

But this will not run for longer to eradicate the amount of humidity essential from the air.

Therefore, this will result in the air feeling cool.

However, this indeed can be clammy.

Would you choose a clammy fit for your home?

Obviously not!

To get rid of the clamminess, you will turn down the thermostat.

And not only this, but it can also lead to more disastrous outcomes.

An appropriately sized unit runs comparatively longer enough to eliminate the essential humidity amount from the air and allows you to sit comfortably at a higher thermostat setup that ultimately saves money on energy bills.

Make a difference with TEL Constructions’ help!

Choosing a professional partner to get hold of the suitable HVAC unit for your home can take your headache away.

Not only is choosing the best fit for the space but the one that is easier on your pockets.

TEL Constructions experts work closely with you to find the perfect fit based on the budget and requirements.

Here are the tips for choosing the best HVAC system for home.

1. Check the HVAC Unit ratings.

When choosing the HVAC systems, one must consider the ratings and how it impacts the home’s comfort.

This depends on the following:


AFUE is the average fuel utilisation efficiency that measures the efficiency of oil-fired furnaces and gas.


SEER is the Seasonal Energy Efficiency Ratio that is the standard rating to measure the air conditioner and heat pumps efficiency.


HSPF stands for Heating Seasonal Performance Factor, which is used to measure the heating efficiency of the heat pumps.

2. Considering the total costs.

When choosing a new HVAC unit for your space, consider the initial costs to purchase and install the unit.

But do you know that you must also take care of the long-term costs?

Remember, your HVAC unit is a long-term investment.

So you must also consider the long-term impact of the unit.

Rather than just focusing on the initial costing, choose to consider the long-term costs as well.

And apart from it, our experts have already shared the essential information about the unit.

But remember, TEL Constructions experts help you get hold of the best fit for your space while redefining the entire home project. Individual services might not work.
