« Underfloor Heating Applications
These systems are designed to provide full comfort heating to all types of accommodation, installed during construction of the property utilising the design floor structure.
They are designed with lifestyle and economy in mind, utilising the most suitable electricity tariffs available to give you:
The systems can be a mixture of storage and direct acting elements, the storage element being controlled through an anticipatory controller and the direct acting through individual programmable thermostats.
Underfloor Heating (UK) with the support of Europes leading manufacturers will design and install to your requirements.
Direct heating systems require an installed output of up to 150 W/m2 and the heating cables placed near the floor surface. Normally, heating cables or mats are placed in the lower part of a concrete layer with a maximum of 5 cm.
The installed output shows how many watts per m2 (W/M2 ) have to be installed in order to cover the heat loss and provide the necessary heating. The heat loss mainly depends on the climate conditions and the insulation in the building. We will assume that information about the heat loss is available.
When the total heating output for a room is to be determined, the available area (m2) has to be estimated. This means that the area covered by cupboards, bathtubs, lavatories, etc. has to be deducted from the total area of the room. Therefore, the required installed output will be proportionally higher on the usable floor space.
In order to ensure a quickly responding heating system, the total calculated output has to be increased by approx. 30%. The result of this calculation will reveal the required output for the heating element - cable or mat.
Normally, the calculated output for a new and well insulated building would be 40-60 W/m2 and up to 150 W/m2 in the bathrooms. If the calculated installed output is higher than 150 W/m2, we recommend that additional heating systems be considered.
In houses with large glass and door areas we recommend the use of rim zone heating. The installed output in a rim zone area is approx. 200 W/m2. For further information about rim zone heating, please refer to the paragraph "Accumulating heating".
When the total required output has been calculated, the cable or mat with the nearest and higher output should be chosen.
Devimat 150 W/m2
(An alternative to the Deviflex System)
accumulating heating is designed to be used on the ground floor of houses, offices, and factories where there is an opportunity to use electricity during low tariff periods. The heating cables are embedded in a thick layer of concrete (7-15 cm) that accumulates the heat produced during the low tariff period.
Our heating systems can be installed in all kinds of wooden floors as long as the installation prefaces are observed. The devireg 550 or 540 electronic thermostats, by means of which the temperature of the floor may be limited, ensure that the temperature in the floor construction always corresponds to the tolerance level that the manufacturer of the floor surface has recommended.
