A dry option for a quick installation
Which OneZone™ should I choose?
This depends on your project. If you are building a new extension, a screed OneZone™ is an affordable option that is simple to install as part of the build. The floating OneZone™ is a completely dry system – ideal for timber frame properties – that can also be used for retrofitting into existing properties with good levels of insulation that can tolerate some height build-up. Finally, LoPro™Max is the best solution for renovation projects where insulation levels may be difficult to improve or where there are large amounts of glazing, such as bi-fold doors. It offers a low total height build-up of 22mm and a high heat output to combat any heat losses.
Why is LoPro™10 not available as a OneZone™ kit?
LoPro™10, Nu-Heat's lowest profile UFH solution at 15mm, is not available as a OneZone™ system because of the intricacy of its layout. LoPro™10 can still be installed in a single area but it will need a bespoke design.
How long will it take to install a OneZone™?
Installation time varies depending on the type and size of OneZone™ you choose. Some average times are shown below:
|Kit size||Screed OneZone™||Floating OneZone™||LoPro™Max OneZone|
|10m2||8 hours||9 hours||14 hours|
|30m2||14 hours||16 hours||26 hours|
|60m2||20 hours||22 hours||32 hours|
Independent boiler control, rather than connecting to an existing radiator circuit, can increase the installation time, as it will include additional plumbing and electrical work.
What's included in a OneZone™?
A OneZone™ kit includes everything you need to install the underfloor heating. LoPro™Max also includes the correct amount of self-levelling compound required to finish the installation so that it is ready for the chosen floor covering (screed systems do not traditionally come with screed or compounds).
How is LoPro™Max installed in a kitchen with existing units?
Where there are no appliances, kickboards can be removed and a temporary batten fixed in place to hold the edge isolation strip and self-levelling compound in place. This method can also be used where appliances have adjustable feet with sufficient travel to allow them to be moved in and out. Where this is not the case it may be possible to remove the worktop and lift the appliance into place. We have even come across a situation where the installer routed out the underside of the worktop to give additional height.
What is the depth of each OneZone™ system and what size is the underfloor heating tube?
The OneZone™ systems all use a flexible and extremely durable 10mm underfloor heating tube.
- LoPro™Max: 22mm in total
- Floating: 15mm + an additional chipboard layer that should be installed over the underfloor heating panels in order to create a stable floor and to avoid damage to floor coverings
- Screed: The total depth depends on the screed used. Standard sand & cement screed would be 65mm, or 55mm for liquid screed
How far away from the boiler can the manifold be?
The boiler can be anywhere in the property, but for ease of installation it is best if the boiler is no more than 20 metres away. This is purely to do with the pipework going from the manifold to the boiler as the longer the pipe, the more resistance.
A OneZone™ that is within 20 metres from the boiler can be plumbed with 15mm pipe. Where the boiler is more than 20 metres away, a bigger pipe will be needed – generally 22mm.
Can the boiler be on another floor?
Yes, in the same way that a radiator can be on a different floor to the boiler.
What are the distributors on the system and how do they work?
Distributors work in a similar way to the manifold. They take a large underfloor heating tube and split it into several smaller tubes. The larger tube can carry sufficient litres per minute to feed several smaller tubes.
How is a OneZone™ integrated into an existing radiator circuit?
To integrate the underfloor heating into an existing radiator circuit, avoiding the need to run pipework right back to the boiler, you T-off the radiator circuit in parallel to an existing radiator.
Can the underfloor heating run and be controlled separately from an existing radiator circuit?
Yes, it can. To do this the underfloor heating must be T'd off of the boiler primary pipework, rather than installed into an existing radiator circuit.
