Summary of content
Explaining underfloor heating, how it works, its contribution to energy efficiency and its benefits, including:
- Compatibility with low temperature heat sources, such as condensing boilers and low carbon heat pump technologies
- Delivering stable/constant temperatures for occupants
- Delivering comfortable temperature profiles in rooms
- Allowing flexibility in interior design of rooms
- Safety: no hot surfaces which might injure children or the elderly
- Maintenance: underfloor heating systems are designed for easy maintenance.
Describes the key components of an underfloor heating system and the main steps in the installation of systems in timber floors and concrete floors.
Explains the heat sources that can be used with underfloor heating and considerations for each, including gas, oil and biomass boilers, heat pumps and community heating systems. Considers how systems deliver heating and hot water.
Includes guidance on the following:
- Primary pipework
- Manifold assemblies
- Location of manifolds
- Maintaining water flow
- Preventing leaks
- Secure fixing
- Insulation around manifolds
- Labelling of manifolds
The floor as a heat emitter
Making sure that the underfloor heating is effective. This section includes guidance on:
- Layout of pipework loops
- Heat output of emitter/floor
- Insulating the floor
Includes guidance and illustrations for concrete, timber, floating and acoustic floors.
Programmers and controls
This section explains the Building Regulations guidance for controls and gives guidance on the using controls and settings for programmers.
How to pressure test the installation and inspect for quality of installation.
Commissioning and maintenance
Includes notes on water treatment and maintenance checks of the manifolds.
An introduction to what should be included in handover material/user guidance for residents and home owners.
