Everything you should consider when installing UFH

regulate heat across a whole floor. However, more and more people are now using UFH in single rooms such as conservatories and extensions. It is therefore very important for homeowners to understand how best to approach this type of installation. Nigel Sanger, Divisional Director – Technical Support at JG Speedfit, explores the different options available to homeowners when considering single room UFH.


In general, underfloor heating systems are installed across multiple rooms – for example across the ground floor of a property. The standard installation process is based around the connection to a manifold, with multiple ports. Each is used to distribute water to different rooms in line with their individual heating requirements. This manifold is usually coupled to a blending valve which allows the UFH system to run at a lower water temperature than central heating and hot water circuits. Moreover, each room has its own thermostat which allows the manifold to direct water to every room. However, what happens when a homeowner decides to use a single room UFH as opposed to an entire floor? Larger projects suit the above method, but this approach is less suitable for a single room. Achieving a

nderfloor Heating (UFH) is most commonly used by homeowners to efficiently

warm conservatory can be done via a much simpler method instead, namely single room UFH packs which offer their own unique benefits.


Installing a single room UFH to its own dedicated circuit is a preferred method for most homeowners as it allows complete control over the heating in that room. It can be activated independently of the central heating system and is a lot more effective. Furthermore, it allows the heating to be tailored to provide the greatest level of comfort, thus maximising energy and cost savings.


When fitting UFH into a single room, you will want the installation to be as easy as possible, because it could be an unfamiliar process when doing your own conservatory or extension. To overcome this challenge, the Room Packs from JG Speedfit have been designed to offer maximum ease of use and functionality to the user. Its pre-configured systems reduce installation times significantly with its intelligent design and each pack comes with everything necessary for spaces up to 30sqm. Unused parts and spare pipes are now a thing of the past! Fitted with the latest A-rated pump, the control unit has integral ball valves for isolation from the primary heating system. It also includes an adjustable


DON’T FORGET ABOUT THE SCREED Finally, make sure a variety of BS 8204 approved screeds are used for this type of installation. Typically, 65-75mm thick for sand-cement types or 40-50mm for liquid pumped screeds work best. It is imperative that screed should be laid as soon as possible after the pressure test and should be left under pressure during the screeding process. The floor finish must be laid when the screed is fully cured. Single room underfloor heating is growing in demand and JG Speedfit is helping homeowners achieve their heating control goals.

blending valve and a six-metre head circulation pump. An anti-vibration mounting bracket is incorporated, ensuring silent operation.

For UFH novice installers, particularly homeowners who are completely new to single room UFH, these room packs provide everything necessary to efficiently and easily fit underfloor heating – with very little wastage.

AESTHETICS AND CONTROLS Homeowners will benefit from more space for interior design as there are no radiators in these spaces. Single room UFH can also be remotely controlled via the JG Aura app, from anywhere, at anytime.
