Thanks for your letter dated 2nd October (received last week) advising me of the approved installers. In fact, someone at Ippec had already rung me with their number.
They were able to fix my heating system, which is now working very well, and I am very grateful to them, and you for supplying their details. Thanks very much. F. Lewis, Devon.

The PEXATHERM Ceiling Heating & Cooling Systems

A new high performance system, providing an alternative solution to floor heating
 

Let the sun in
Radiant heat travels in all directions. This is how the sun heats the earth. Only warm air rises when heated. PEXATHERM ceiling heating is like letting the warmth of the sun through a glass ceiling on a cold day. The warmed ceiling radiates heat to the room quickly and evenly, as with all good underfloor heating systems.
The ceiling cover of plasterboard, or match board provide little resistance to heat transfer when compared with floor covering. All the benefits of invisible and energy saving floor central heating are retained, and new ones are added into one integrated system.

The new Pexatherm Ceiling system is ideal for existing buildings and extensions where floors cannot be disturbed or unsuitable for underfloor heating. The thin layer of plasterboard only covering the system makes it a high performance system since there is little resistance to heat transfer from pipe to room. Hence the response time of Pexatherm ceiling heating is much faster. The water temperature in the ceiling is even lower that in the floor with underfloor heating making the system even more efficient when used with condensing boilers and heat pumps.

System Details
The heat ouput from the Pexatherm PEX-ALU-PEX pipe is diffused into black aluminium plates which are in contact with the plasterboard. The heat is then transfered into the ceiling and radiates throughout the room.

the Pexatherm ceiling system uses the same underfloor heating manifold to distribute the heating pipe to different rooms. Thermostat and actuators at the manifold are used to control the temperature in each room. Again as in the Pexatherm underfloor heating system. Water temperature in the ceiling is also controlled by a mixer or at the heat source to regulate the output of the system.

Two types of plates are offered with the Pexatherm ceiling system

The Ceiling Package
The Pexathern ceiling package includes Multilayer PEX pipe coils, black ceiling panels with double or triple pipe grooves in size 1200 x 450 or 600 mm Distribution brassxmanifold, mixer valve, pumps, programmable master thermostat and instruction. Pipe layout drawing, Individual room control and insulation are available separately.

Ceiling Cooling
By virtue of its position, the ceiling system can cool the room when chilled water is run in the pipes. The cooled ceiling surface cools the layer of air in contact with ceiling which then creates gentle convected resulting in the cooling of the whole room. Only cool water at about 10 deg. C need be used, requiring no or little refrgiration, to achieve comfort cooling temperature.
