What Are Underfloor Heating Systems?

There are several ways in which people can provide heating to their homes. The most common one is a central heating system which uses hot water from your boiler to heat your home through radiators. Other heating methods include electric and gas heaters.

There is, however, another heating method that is considered to be highly effective: Underfloor heating systems. The system uses hot water or electricity to heat your floor through a series of water pipes of electric cables. These systems are often insulated with Underfloor Heating Screed Services in London to enhance their heat efficiency.

Types of underfloor heating systems

There are two types of underfloor heating systems. A wet or water-based underfloor heating system and a dry or electric underfloor heating system. 

Wet or water-based underfloor heating systems

The wet system includes a series of pipes installed underneath your floor. Hot water from your boiler passes through these pipes, and the floor becomes hot by exchanging heat from the pipes. Wet systems can be connected to a gas boiler, solar panels, a heat pump, or any source of hot water. Wet systems can be used for heating as well as cooling your floors.

What are the components of an underfloor heating system?

  • Design: The design or the layout of water pipes may vary according to the shape of your room. The best design is selected to maximise the efficiency of the heating system. Pipes of small diameter are selected but are high in number. This increases the surface area and therefore enhances the heating ability of the system.
  • Manifold: A manifold is responsible for distributing hot water from the source to where it is most needed. It has mixer valves to control the mixing and flow of hot & cold water. It is usually made of stainless steel.
  • Pipes: PE-RT, PEX-A, or other composite materials with high thermal efficiency are used for manufacturing the pipes. These are not ordinary pipes. They are specially manufactured to enhance thermal efficiency while preventing oxidisation.
  • Pumpset: A waterproof pump with a temperature gauge similar to the one used in a central heating system. 
  • Thermostat: Automatic thermostat for controlling temperature.
  • Control Center: Control Centres allow you to control the heating components such as thermostats, etc. They have a display that shows you the temperature and other statistics.
  • Insulation: PIR, EPS, or other insulation panels are installed to minimize heat loss and enhance heating efficiency.

Dry or electric underfloor heating systems

A dry or electric system replaces pipes with electric cables. Electricity passes through these cables, heats them, and your floor becomes hot by exchanging heat from these cables. 

What are the differences between wet and dry systems?

The purpose of the wet and dry systems is the same. However, the modality and the running cost may vary. There is another difference between the two systems. A wet system can also be used for heating and cooling your floors, while a dry system can only be used for heating.

How can you improve the efficiency of the underfloor heating system?

Underfloor heating systems are highly efficient and can be increased in several ways. Installing high-quality insulation sheets will reduce heat loss and enhance the heating. The type and material of insulation panels or sheets will play a significant part. Improving your home’s wall and ceiling insulation will also increase efficiency, but the most effective method is using a liquid screed.

What is liquid screed, and what is it used for?

A liquid screed is a mixture of small-size aggregates used to create a uniform surface over concrete floors. It can be pumped to fill all the voids in your underfloor heating system, thus enhancing the process of heat exchange and reducing heat loss. Underfloor Heating Services in Basingstoke involves the application of a very thin layer of screed, allowing more room for insulation sheets or panels, so you can use thicker ones and enhance your insulation further. 

What are the benefits of using underfloor heating systems?

  • They follow the bottom-up process for heating your room through radiation. The air at the lowest level gets hot and rises while colder air falls for heating. This cycle ensures a more uniform and even heating across the room.
  • Unlike conventional heating methods, the efficiency of underfloor heating does not fall at lower temperatures, and therefore it cuts down your energy bills.
  • No space requirement as the entire system is installed underneath your floor. No radiators are needed.
  • More hygienic with low emissions and carbon footprint.
  • Much safer as no heating components are exposed.
