How Do Central Heating System Work?

Providing warmth and comfort for their homes is the topmost priority of most homeowners like yourself in the United Kingdom, meaning that they rely on central heating systems to efficiently heat their homes without boring a hole in their pockets.  

However, before we answer how central heating systems work, we first need to know what it is and what kind of heating system you have in your home.  

What is a Central Heating System? 

Central heating simply means that your home is heated from a central location, in this case, a boiler, and spread throughout your home via pipes connected to the boiler. The heat circulating in your home, usually through connecting pipes from a boiler, is adjusted via thermometers, radiator valves, or time controller, known as a Central Heating System. 

According to the Office of National Statistics, 95% of homes in the UK have central heating, with 83% of those heating systems powered by natural gas from the national gas network.  

Which Heating System Do You Have? 

Generally, three central heating systems are available in the UK, wet and electric storage systems, while the demand for warm air systems is waning. 

Wet System 

There is a high probability that you have a gas-powered wet central heating system. If you have a wet system, your boiler uses fuel to heat water circulated in your home via radiators or underfloor pipes. 


  • Cost-effective 
  • 3X cheaper than electricity 


  • Pricey to install 
  • Requires servicing and maintenance 

Electric Storage Heaters 

Bricks that are highly energy-efficient in storing vast amounts of heat fill up radiators charged overnight with off-peak electricity to heat up the home during the daytime when needed. Electric storage heaters are wall-mounted and look just like a radiator. 


  • Cheaper to install 
  • Requires little servicing 
  • Energy-efficient 


  • Eat up wall space 
  • Disrupts interior decor 

Warm Air System 

Usually found in older properties, warm air systems suck cold air from the outside, heated by your boiler, and the heated air is circulated throughout your home via ducts. 


  • Efficient 
  • Heating a room is very swift 
  • Eliminates damp  


  • Dwindling popularity 

How Does Your Central Heating Works?

Pipes connected to a heating source (boilers in most cases) are used to transmit heat around the home either via radiators or underfloor heating. There are four parts to your heating system: a boiler, pump, pipes, and radiators of underfloor heating. 

This is simply how it works; your 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. 

How Much Does Central Heating Cost?

If there is no central heating system on your property, then you will need to purchase one. 

  • A boiler 
  • Radiator or Underfloor Heating 
  • Pipes 
  • Cost of Labour 

The cost of the loft conversion service you acquire depends on various aspects.

How Much Does Wet Underfloor Heating Cost? 

Underfloor heating is an excellent way to heat up your home efficiently, making it a better alternative to radiators, which costs a lot to run while leaving “cold spots”. You can either choose an electric underfloor heating system or a wet underfloor heating system as they both can be installed with almost any flooring and have the same benefits.  

What makes a wet underfloor system different from an electric underfloor system is the cost of running. Running a wet underfloor heating system is cheaper than an electric underfloor heating system. A critical understanding of how it works is crucial, which is something to consider before learning the cost of installing and running this system  

How it Works 

It works almost the same way radiators work, just minor differences. With wet underfloor heating, pipes connected to a boiler transport warm water throughout the floor to heat up the room. A wet underfloor system usually runs at a lower temperature, between 27C and 31C (the exact temperature is determined by the type of flooring you have). 

How to Install Wet Underfloor Heating System 

The steps below outline the process of installing an underfloor heating system, whether wet or electric, with slight variations; 

  • Ensure your boiler supports the heating system 
  • Zone the room layout and fix the pipes using fixing clips 
  • Connect the pipes to the heating system and thermostat 
  • Hold the pipes in place with an insulating screed 

The cost of wet underfloor heating totally dependent on the size of the room, type of flooring, and the installer. Even if you are a die-hard DIYer, it is advisable to leave the installation to professionals. You usually don’t require planning permission to install an underfloor heating system except you live on a designated site.

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

A large chunk of the finances for the average homeowner in the UK is spent on electricity bills. The power industry regulator Ofgem pegs the amount of money spent on heating and power in the UK at £1,254 annually. Homeowners are looking for innovative ways to reduce their energy bills without compromising on their HVAC systems. 

In this article, we handpicked 5 of the best HVAC systems in addition to their best qualities to help you make an intelligent and well-informed decision. 

5 Types of HVAC System

1. Standard Air-Conditioning and Furnace Split Unit 


  • Energy efficient 
  • Mild on your pocket and the environment 


  • Can lead to carbon monoxide poisoning 
  • Not a healthy option, especially if you already have allergies 
  • Propensity to disperse dust and dried air during the winter 

This setup uses a lower fan to heat or cool air, one of the earliest systems circulating via the ductwork throughout your home. The unsavoury part of this setup is the ductwork requirement can pose serious health risks.

Air conditioning system

 2. Standard Heat Pump with Air Handler Split System 


  • Lower operating cost than boiler systems 
  • Low cost of installation 


  • Can spread pathogens and allergens in your home 
  • Not very efficient 

This setup makes use of the heat pump for producing both heat and air conditioning, using a refrigerant in its system. The handler system pushes the air throughout the home to provide comfort.  

3. Boiler with Radiant Heat and Airconditioning 


  • Offers very comfortable air 
  • Offers versatility 
  • Energy-efficient 


  • Takes time to heat up 
  • Expensive to install 

A boiler setup circulates water it has heated to a high temperature through conduits, and they come in different configurations; electric, gas, propane, or steam boilers.  


4. Mini-Split Heat Pump System 


  • Highly energy-efficient 
  • Requires no ductwork 


  • High cost of installation 

Resembles the standard heat pump but instead has multiple spread out in the home. Known as the most efficient system, second only to the geothermal system, this setup is rising in demand because of its lower cost.  

5. Geothermal Heat Pump System 


  • The most energy-efficient solution 
  • Highly durable as it has a lifespan of over twenty years 
  • Saves you tons of money on electricity bill 
  • Reduces carbon footprint 


  • High initial installation cost 
  • Repair cost bores a hole in your wallet 

A significant part of this system is the use of natural temperature. This system uses the connecting underground pipes to transmit water under the ground where it is warm or cool as the case may be. By far the most obvious choice for homeowners who are concerned about the environment. 

Buying a heating and air conditioning setup for your home should not be like finding snow in the Mojave Desert because you don’t know which system to settle for.

You can speak with a TEL Construction consultant, and they’ll be more than happy to point out the best plan for you so you can protect your family from the unpredictable UK climate.
