This rig is ideal for introducing the concepts of underfloor heating and to the language and terms that are used commonly
when discussing, installing and designing UFH systems. The layout of the rig allows physical examination of a range of
heated floor construction, and it can be used to demonstrate how UFH systems work and how they are controlled. It can also
be used to show and explain why some forms of UFH are ideal for use with sources of renewable energy, and why some are
Key features include:
Situated at the front end of the rig is a complete working manifold assembly. This enables the trainer to explain how pipe
circuits are created within the structure of a floor and show how a room thermostat can control the flow of warm water into
each heating circuit. It demonstrates how a demand from a room thermostat can open the appropriate control valve(s) and
activate the boiler/heat pump. It also shows the gradual opening of control valves and how the pump and water mixing valve
function, and should be adjusted.
- 2 forms of pipe-in-screed UFH
- 5 forms of timber floor UFH
- 1 form of UFH overlay suitable for refurbishment projects
- A functional 3-port manifold assembly complete with wiring centre
- 2 forms of room temperature thermostat
The rig incorporates two different types of room thermostat. One is wired to control a single actuator and the other is
wired to show how a single room thermostat can control two actuators and consequently two pipe circuits.
Each rig is supplied with a set of progressive step-by-step teaching notes and diagrams. These
include basic explanatory notes about how UFH works by comparison with radiator heating, the floor temperatures involved
and describe how the training rig should be used to illustrate the training.
The rig is intended to provide any student who wishes to go on to learn more about UFH and how UFH systems should be
installed, commissioned or designed, with sufficient understanding to be able to benefit from subsequent classroom studies
which can lead to NVQ Level 1 or Level 2 qualifications, or simply to become a knowledgeable installation-trainee.
