Edge Insulation Roll

Perimeter insulation rollEdge insulation roll or perimeter insulation as it’s also known is an absolute necessity in every wet underfloor heating system with a screeded floors. It’s purpose is not only for insulating the edge of the room to prevent heat loss as many people have come to believe; it also offers huge advantages in getting the best performance out of your underfloor heating system while allowing for the expansion and contraction of the screed to prevent cracking and damage.

– Edge insulation greatly helps to insulate the perimeter of the room to prevent heat loss into the walls and forcing heat back into the room

– The insulation must be installed at the full depth of the screed in order to stop further heat loss through cold bridging

– the thickness of the insulation provides cushioning during expansion and contraction of the screed to prevent the risk of cracking and damage to screeded floors

– perimeter insulation should never be replaced by cutting thin strips of insulation board. This creates a health and safely risk on site and serves completely the wrong purpose with minimal gain

– edge insulation is especially useful for diffusing heat in places where pipework is close together, typically when several pipe runs occupy the same route on the flow and return to manifold

– the polythene backing helps to stop screed entering between the edge insulation and floor insulation and is particularly welcome when using a liquid screed.

– the perimeter insulation we sell is 120mm wide, 8mm thick, available in 25 & 50m rolls

– any excess left showing above the screed can be easily trimmed away once the screed has hardened

Never overlook the importance of fitting perimeter insulation with your underfloor heating system, including the areas around columns and door frames. Without sufficient space to expand and contract a screeded floor with crack and damage which over time will eventually require replacement; an expensive option which can easily be avoided during the early stages of installation.

Underfloor Heating Thermostats

Underfloor heating thermostats are arguable just as important as the underfloor heating system itself. Without them you have no way to control the heating rendering the it as good as useless. Heating controls have come  long way from the old turn dial thermostats and we have options to suit all tastes and budgets.

We supply one of the leading brands in heating controls that have made a name for themselves in underfloor heating. Heatmiser make and supply an outstanding range of controls ranging from basic turn dials all the way up to wifi controls you can access through your smartphone.

Below is an overview of each type of thermostat that Heatmiser do and briefly

Salus ERT20Electronic Turn Dial– these are the most basic kind of thermostat you can buy. Electronic turn dial thermostats are cheap, functional and simple to use with zero fuss and basic operation. They have no programmable features are ideal for use in smaller rooms or those areas less used in the home where funtionality, features and looks are not important.


Heatmiser PRTDigital– digital thermostats are the modern standard these days. They have an illuminated digital display screen with push buttons to increase or decrease the temperature. Most digital thermostats also allow you to program the temperature several days in advance known as digital programmable thermostats. We have several of types of digital programmable stats, the most popular one being the Heatmiser PRT.


Heatmiser PRT-TSTouchscreen– touchscreen thermostats are the next step up and generally offer the same features as the digital thermostats with the main difference between them being operated by touching the screen. Slightly more expensive, they certainly look the part in any modern home and are a great addition to any underfloor heating system. Many customer often choose to use touchscreen thermostats such as the Heatmiser PRT-TS in the high traffic rooms such as the kitchen and living room while opting for the cheaper digital stats around the rest of the house.


Wireless– wireless thermostats are ideal for when you want to relocate a thermostat without having to go through all the hassle of re-wiring it. By replacing the current thermostat with a wireless receiver you can the place the thermostat unit anywhere you want in the house within a 100m range- rest if on a desk, the kitchen tops or on the bedside cabinet. Wherever works for you, a wireless underfloor heating thermostat like the Heatmiser PRT-W will give you the freedom to chose how you control the heating from a place that’s most convenient for you.


Heatmiser PRT-NNetwork– network thermostats are the state of the art underfloor heating control option. Since they run off a 12v system, upgrading your current 230/240v thermostats to network control can be very expensive since it requires completely re-wiring your house with a screencap 5 shielded cable with 8 core twisted copper. Because of this we only recommend installing network thermostats on new builds. But for those who do choose network heating controls you will have the ultimate control unlike anything else. By installing the Heatmiser PRT-N or Heatmiser PRT-NTS touchscreen network thermostat to the Netmonitor you can control your heating via any web browser. And with the Netmonitor plus you can set the heating to any room in the house just by sending a text.

Choosing your underfloor heating thermostat all comes down to how much control you want to have, how modern you want it to be and how much you want to spend. If you’re unsure about what to choose feel free contact us and we will be happy to advise you on what your options are that best suit your needs and budget.

The importance of edge insulation

edge insulationEdge insulation is a key component in an in-screed underfloor heating system and should never be overlooked or skimped on as its function is extremely important. It’s main purpose is to provide space for the supple flex and expansion of the floor during temperature change as well as providing an layer of insulation against the walls. Without this cushion the screed has no room to expend and over time will begin to form cracks, reducing the effectiveness of your underfloor heating and furthering the risks of pipe damage.

Edge insulation needs to be put against all points around the room that touches the screed, not just the room perimeter  This includes any centre columns, inner walls or solid features within the room itself. Bear this in mind when working out how much you’ll need for the installation.


Some important points to remember:

  • Edge insulation is only used with screeded zones and is not needed in zones using aluminium spreader plates
  • The edge insulation should be laid partly underneath the insulation boards with the remainder running up the walls to be higher than the screed and finished floor level. Once the screed has dried the excess can be cut away with a blade for a neat finish.
  • The polythene layer should point inwards to the room with the foam against the wall. The other way around and the screed would be absorbed and solidify the edge insulation and void its purpose




Pipe Decoiler

Pipe Decoiler

The pipe decoiler easily dispenses or recoils the required amount of pipe from a spinning carousel making the pipe laying process much easier while reducing the risk of kinking. Made from a tough and durable steel frame, the adjustable arms can hold all types of underfloor heating pipe and coils up to 500m (58kg). Can be assembly or disassembled in just a few minutes and will fit easily into a small van. Highly recommended for handling coils larger than 100m.


  • Quick and simple dispensing of pipe
  • Reduces the risk of pipe kinking
  • Tough and durable steel frame
  • Suitable for all types of underfloor heating pipe
  • Holds coils up to 500m
  • Assembled in 5 minutes


What pipe centres do I need to use?

A common question we get asked when people install their underfloor heating is what what pipe centre should be used. This is also raised after quote submissions as often times people are confused why the pipe centres can differ throughout the house. But the answer is pretty straightforward- pipe centres vary to suit the heat requirements for that particular room based on varying factors.

The pipe centres in a wet underfloor heating system is determined by the type of floor covering, the type of room, height of ceiling and what type of heat source is being used. These are some of the most important factors to consider.

200mm centres is recommended in most underfloor heating systems that have hard floors, standard ceiling heights and using a boiler. The harder the floor covering the easier it is to transfer the heat from the pipes to the floor. So any type of tile and stone flooring are good heat conductors that once heated hold the heat well. Wood and laminate are good but being slightly less dense than stone or tile lose the heat a little faster.

If your underfloor heating system is heated by a ground or air source heat pump all centres need to default from 200 to at least 150mm. Heat pumps cannot generate as much heat as boilers can so to balance the loss in temperature  the centres need to be much closer.

Carpets loose heat the quickest and are poor heat converters and because of this any room with a carpet needs to be using 150mm centres minimum if put into screed. If you’re putting in underfloor heating on joisted floors with carpets and using aluminium spreader plates, you’ll need to bring the pipes closer together to 120mm centres since spreader plates aren’t available at 150mm centres.

Points to remember:

  • High heat loss rooms such as those with folding glass doors, conservatories and vaulted ceilings should use 150mm centres as standard
  • An underfloor heating system using an ground or air source heat pump must default the standard centres from 200mm to 150mm as the flow temperature in the system runs slightly cooler than one fed by a boiler.
  • 150mm centres should be used in any rooms with carpets unless the system is installed on joists, in which case use 120mm centres
  • The tighter you bring the centres together the more heat you will produce
