Active Ceiling

An Active Ceiling system provides the highest level of optimal comfort available on the market today. Heat your home throughout winter, and cool it down in the warmer months via one complete system.

ACTIVE CEILING
Why choose Active Ceiling Heating and Cooling for your home?

As the system is totally concealed behind the ceiling drywall sheets, it is completely out of sight as it provides a uniform level of radiant heating and cooling to your home. With no air movement being generated, there is no recirculation or collection of dust, resulting in healthier and cleaner air. These systems are efficient, easy to control and quick to respond as there is no slab to heat or cool.

Grant Aerona3 Heat Pumps

Messana Active Ceiling systems powered by Grant Aerona3 is an affordable air to water heat pump option for the single purpose of heating a medium to large home. The grant aerona3 harvests free energy found in the air outside the building envelope, turning it into warm water for the active ceiling system.

Active Heating
In winter it circulates warm water throughout pipes within the ceiling panels, which radiantly warms your entire home.

Powered by electricity, the Grant Aerona3 heat pump is using an entirely renewable energy which helps reduce the amount of harmful greenhouse gases being released into the atmosphere and in so doing, lowers the carbon footprint of the household.

– Silent
– No air movement
– No dust circulation
– Low noise level ensures quiet operation for the comfort of home owners and neighbours.
– A high level of performance even when its -10°C outside.
– Ultra energy efficient and compared to a gas-fired system saves the equivalent CO2 emissions reduced by a forest area of around 2,500m2.

Grant Aerona3 heat pumps can deliver over four times the amount of energy for every single unit of electricity used depending on the flow temperature and the climate conditions prevailing at the time. Homes utilising this type of heat generator will obviously have a lower dependency on fossil fuels, making them less susceptible to rising fuel costs.

FREQUENTLY ASKED QUESTIONS
Who installs the product?

With the naked panel, the heating installer will hang and connect the panels.

How is the product installed?

The panels are hung between rondo placed at 600mm centers. Each side of the naked panel has an overhanging aluminum flap, which is tacked to the batten using a staple or similar. Connected runs of panels in larger areas are made by pushing two panels together after push fit connectors have been placed in one of the panels.

Each panel run (See panel installation guide) is connected to the manifold using insulated 16mm PEX (no aluminum barrier pipe can be used).

The panels are designed to be ceiling mounted and this is the recommended method, however, they can also be installed on walls which we would recommend being signed-off by a builder or architect.

Does a Messana Active Ceiling system cost more than an Underfloor system?

The installation cost is generally less than an Underfloor system, however, the overall cost needs to be determined on a case by case basis. We are happy to quote both options.

Is it easy to fix accidental pipe piercings?

The pipe can be easily repaired with pushfit coupling joints that do not require a tool.

Do the panels expand and contract when they are heated?

The panels will experience minimal expansion and contraction with the heating and cooling of the system. The temperatures of the panels will typically reach around 40°C in heating mode, and 10°C in cooling mode which results in almost silent operation during the heating and cooling transitions.

What fittings are used to join the panels?

The panels join using pushfit fittings specific to the radiant panels. The pushfit tees used are self-balancing to minimise flow rate balancing at the manifold.

How much of the ceiling is covered?

As much as 70% coverage of the ceiling area is active panels, in high solar gain/high stud areas. Minimum of 50% coverage in low solar gain rooms with low cooling requirement and standard heating requirement. The panels are 2.4m x 0.6m and can be cut in half to form a 1.2m x 0.6m panel.

What temperature will the water be in heating and cooling? How is dew avoided?

In heating mode, the flow temperature for heat pumps and boilers will be calculated by the Vaillant 700 controller. The flow temperature ranges from 25°C to 45°C, dependent on the outdoor temperature.

Using a Vaillant heat pump in cooling, the outdoor controller monitors the dew point and limits the flow temperature minimum to the calculated dew point value plus a safety factor (2°C as default). This could be as low as 10°C.

What the major differences between Active Ceiling and Underfloor systems?

Due to the lower thermal mass of Active Ceiling systems, they are much more responsive than a floor based system and quickly reach operating temperatures.

In cooling mode we can deliver twice as much cooling power with an Active Ceiling system than we can with Underfloor systems.

What are the ceiling design requirements? Will my lighting be restricted?

The panels are suitable for ceiling battens at 600mm centres.

Penetrations up to 80mm between pipes, and 150mm in the centre of the panel diagonally between the ends of loops can be used for penetrations in active panels (see spec sheet for detailed diagrams). For penetrations larger than this, channels with no panels will need to be present.

Who chooses the ceiling panel layout?

Waterware will design and quote the system including the coverage area, the number of active panels required, and system layout plan.

The builder, electrician, and heating installer will usually work together to discuss and agree the final placement.

What is the finishing quality in fire and wet areas?

The naked panel is fitted behind the plasterboard, and so any finish or surface resistance can be achieved.

Are the panels more efficient than an Underfloor system?

Where the panels definitely differ to slab Underfloor is their effectiveness.

- Quick heat up time due to large output per square meter and less thermal mass to overcome
- Not restricted by floor coverings or restricted in performance because of chosen floor coverings like carpet
- Significant cooling effect due to the increased cooling performance per square meter
- Less thermal mass so fantastic response to outdoor conditions

What is the response time and does the panel heat evenly?

With a much lower thermal mass to overcome, the response time for the ceiling panels will be more similar to radiators.

The gypsum panel has an aluminum spreader plate, which encases the pipe and assists in conducting the heat from the pipes into the gypsum and keeps the whole panel at a consistent and even temperature.

Does the EPS layer provide extra insulation?

The EPS foam layer on the gypsum panel has an R value of 1.

But doesn't heat rise?

This is a common misconception.

Hot AIR rises but the ceiling panels operate by radiantly heating the room, similar to how the sun radiates heat to us on Earth.

Heat rising occurs mostly with methods of heating which use convection, such as air driven systems, where with radiant heating the building envelope as a whole is being warmed. Tests of installed product show the gradient of temperature change when the height varies is barely noticeable: 19.5°C at floor level, 20.5°C at 1.7m above floor level (radiant surface of ceiling @ 28°C).

What are the benefits that reflect the higher cost?

Additional value gained from the panels over a slab Underfloor system:

- While a slab Underfloor provides a cooling effect, the radiant ceiling provides much more significant (up to two times per square meter) cooling performance
- Up to three times the heating output per square meter
- A faster responding radiant effect (in cooling and heating) to slab Underfloor
- Additional insulation to the ceiling, R=1

What is the maintenance cost?

The heating system requires its yearly service like any other heating system where the heat source is checked and inhibitor re-added to the system. No panel specific maintenance costs.

Is this an ex-stock item?

Radiant panels are available ex-stock off the shelf but it is recommended to have the panels set aside during the planning process.
