Underfloor Heating

Our clients choose Better Planet for their underfloor installations because of our expertise when it comes to designing low temperature systems that work efficiently with heat pumps. With Better Planet installing both your heat pump and underfloor heating, you get a “one point responsibility” for the heating system and you can rest assured that your heat pump works at maximum efficiency.

Underfloor heating provides comfortable warmth for your property. Better Planet provides tailor made designs and installations which ensure that you get the correct system for your needs.

We are able to offer four main underfloor heating systems that are suitable for almost any floor construction. Our wooden system is particularly unique, providing a low-temperature system that sits directly on top of floor joists. Additionally, we can offer different control systems to ensure you achieve the level of comfort you desire while saving energy and money on running costs.

Underfloor heating is a modern, environmentally friendly heating system that adds value to your property. It can save a significant amount of heating energy and reduce your heating costs. When installed in conjunction with heat pumps, a well designed underfloor heating system will help reduce the running cost for the heat pump.


We offer solutions for all types of floor, here are the most common:

The Screed system is used when the underfloor heating is to be screeded and is suitable for renovation as well as new built. It offers a heating system with a low temperature that can be connected to all types of heat sources.To fixate the pipes prior to screeding the following options are available:

  • Clip rail – rail in plastic with slots that fixate the pipes during the casting.
  • Pipe holding nail – nail made out of plastic attaches the pipes to a cellulose foundation.
  • Pipe ties – a plastic strip that attaches the pipes to the reinforcement net. As this solution is the cheapest and best in terms of heal transfer, it should be used whenever possible.

The Wooden system includes a 22 mm chipboard with slots for the pipes and aluminium heat distribution plates. The slotted chipboard replaces the usual sub floor and is placed directly on the wooden joists. Suitable when renovating as well as when building something new.  Since the chipboard are bearing it is possible to add a thin covering floor. This minimises the insulation effect and the heating system is able to function at a lower temperature.

Screed Boards – boards with a building height of 18mm (pipe 12mm). No requirement for distribution plates. Dry alternative to wet screed systems.

The Floating system is composed by aluminium heat distribution plates and EPS floorboards. It can be used for both remodelling and new construction. To enable installation of thin flooring the EPS floorboards have a very high resistance to pressure.

Floating system 18 – floorboards with a building height of only 18mm.

Floating system 30/50/70 – floorboards with a building height of 30, 50 or 70mm. The thickness of the board that is used depends on the conditions of the facility. The lighter the insulation that is used in the foundation the thicker the board is recommended.


The two main reasons for installing wet under floor heating are comfort and energy efficiency.


The sense of comfort is obvious. Walking on a warm floor gives a cosy feeling, mainly because heat is generated at relatively low temperatures over a large surface. The amount of heat generated by radiation rather than air movements, increases with under floor heating. Radiation instantly distributes heat to all surfaces in a room. Radiators on the other hand distributes heat mainly through air movements causing warm air to move upwards, accumulating under the ceiling where it is not needed, while cold air remains just over the floor.

Most people prefer colder air at head level and warmer air at feet level. That’s why under floor heating feels so comfortable.

Energy Efficiency

Since the under floor heating pipes are spread over a large surface, the water in the pipes does not need to be as hot as for radiators. This makes it possible to design low temperature systems, increasing energy efficiency. While this is imperative for heat pumps and solar thermal heating, it improves efficiency with any heat source.

The actual design of the under floor system is crucial for making it work at low temperatures. Most of our under floor heating installations have been designed to operate with heat pumps and we take pride in making designs that optimised energy efficiency.

Five good reasons to install under floor heating

  1. By quickly heating air close to the floor, under floor heating prevents downdraughts.
  2. Releases less dust than radiators since there is less air movements.
  3. Less clutter along the walls, making it easier to furnish the rooms.
  4. Comfortable
  5. Energy efficient
