For a qualified installer, Polypipe underfloor heating systems are simple to fit. Additionally, underfloor heating can be planned into a new renovation, new build or a single project.
Yes, and our range incorporates a wide variety of control products: including single zone control, allowing upstairs and downstairs to be controlled separately and individual room control,
allowing you complete freedom over the temperature in each room.
No, generally underfloor heating solutions are quicker and cheaper to install than most other systems. As the installation of our underfloor heating is completed in one stage, it can reduce
the cost, as well as the length of time the installers are on site for.
No, and it can be more economical to run than a radiator based system, as the water is kept at a lower temperature to produce the equivalent heat output. Underfloor heating puts a smaller
demand for heat output on the boiler, it is ideally suited to achieving maximum economy from a condensing boiler or heat pump.
Yes, as they are connected to your existing heating they can be more economical to run than electric systems. All our underfloor heating systems use warm water and emit heat across the entire floor
surface, providing an even and comfortable heat throughout the room.
Yes. It is possible to install a Polypipe underfloor heating system in to an existing radiator (or other heat source) installation as all of the necessary components are supplied within our underfloor
heating design package.
underfloor heating can be used as either the main or secondary source of home heating. This will depend on whether it is a new build property or a renovation project. Our systems are all compatible
with standard central heating boilers and are especially suited to condensing boilers. All Polypipe underfloor heating solutions can also be used as stand-alone systems.
Our unique overlay system is laid over existing solid or timber floors and is ideal for single room retro-fit projects or extensions.
By using our Zonal Regulation Unit (ZRU) it is possible to add an underfloor heating system (to a maximum floor area of 30m2) to your project without needing to fit a manifold.
The ZRU is designed to be connected directly in to your existing heating system and be temperature controlled using a simple volt free room thermostat.
In theory, there are no restrictions on the type of floor coverings used with underfloor heating systems providing that a) the product is suitable and b) our design team has
calculated that the floor covering in question will not have an adverse effect on the overall performance of the system. In a modern highly insulated building, where the heating
demand is lower, the use of high resistance floor coverings, such as carpet, will not be an issue. However, in older buildings, where higher heat losses are common, the use of
more conductive floor coverings such as ceramics or stone tiles would allow more heat to transfer into the room.
No. If your project is planned correctly there is absolutely no reason why installing underfloor heating should delay progress. Our underfloor heating systems can be quicker to install than many
other underfloor systems and the unique overlay system can be installed easily in existing homes and with Polypipe systems available from a wide range of nationwide stockists,securing what you
need is quick and easy.
As there are no joints used below ground in a correctly installed underfloor heating system there is little, to no, risk of a leak developing once the system has been installed and pressure
tested. If a leak were to appear due to manufacturing defect, the pipe is under warranty for 50 years.
The pipes in your underfloor heating system are warrantied against manufacturing defects for 50 years. As the pipes are made of polybutylene they will not be affected by corrosion or scaling
and so the system’s performance will be maintained throughout its working life expectancy.
No, all our underfloor heating systems are virtually maintenance free, and all our underfloor heating products are covered by our industry leading guarantee.
Yes. There is no reason why either air source or ground source heat pumps cannot be used with underfloor heating installations. However, due to the lower flow temperatures that are produced by
these types of appliances it is essential that your system is correctly designed to ensure that it is capable of operating efficiently and meeting performance requirements.
This is really a matter of personal choice. Given that the underfloor heating pipe work will be in the floor for many years but during this time the kitchen layout may be changed several times,
some people choose to run the pipe under the units so as to allow for ‘future proofing’ the system. When systems are installed in this way it is common for some insulation material to be pushed
under the units before the bottom kick strip is fitted. This insulation will allay any concerns that the unit interiors will overheat.
The typical floor surface temperature of a correctly designed and installed underfloor heating system should be between 26°C and 29.9°C depending upon the type of floor covering used.
As the temperature of the palm of your hand is usually around 30°C the floor surface should feel comfortably warm but not hot when touched.
Typical radiator systems operate at much higher temperatures than underfloor heating systems and rely mainly on heat convection produced from a very small heated surface area.
underfloor heating systems work at a much lower temperature and use mainly heat radiation across the entire floor surface area. Although this type of ‘radiant’ heat distribution
provides a more even room temperature and better comfort levels, it does not lend itself to rapid heat up times. In order to compensate for this, we recommend that you use a thermostat
feature called ‘set back’ which holds the system at a lower room temperature during periods of non-use. This set back temperature is usually 4°C lower than your preferred occupied
room temperature and enables the system to have a much faster heat up and recovery time.
No. Under no circumstances should the system be used to accelerate the drying out times of screed flooring products as this could lead to curling or cracking of the floor.
