Nordic Geothermal can provide the customer with the complete package. The customer can choose air or water source heat pumps, under-floor, fan-coils or aluminium radiators in any combination and can also choose heating only, heating and cooling or either with domestic hot water production.

If you have CAD drawings of your building please e-mail them to us for a quote. If you only have sketches you can scan and e-mail these and we will produce a CAD drawing to use for your quote, free of charge.

The typical under-floor package includes a detailed piping plan of your house, and designed and delivered to site within 7 to 10 working days of order, to any of the countries in Europe that we serve.

The package normally includes:

· 15mm Under-floor Heating Barrier pipe (BS 7291 Class S approved).

· 19mm Corrugated ducting for protection of pipe-work if needed.

· Under-floor Heating manifolds located throughout.

· Thermostatic mixing valve located at each manifold.

· Digital thermostats for control of each individual zone, with night-time set-back facility.

· Rapid Rail fixing system for fixing of pipe-work to insulation.

· Grundfos 25/65 circulating pump located at each manifold.

· Full design specification including all necessary schematics.

· Installation DVD

· Printed manual

Not supplied:

Primary pipe-work from boiler house to manifold locations.

Insulation to be laid prior to installation of pipe-work as well as edge insulation for all external walls.

Modern under-floor heating systems are clean, comfortable, and economical to run, virtually maintenance free and offer tremendous energy saving potential.

Advantages of under-floor?

Conventional heating systems (using convector radiators) provide warmth within a space or building by heating the air in the room. By comparison, UFH transfers heat from a very large surface area, which is only slightly warmer than the room. Floors are warmer and the floor to ceiling temperature and humidity levels remain more constant producing a more comfortable environment for occupants. The heated floor operates at low temperatures and will not cause convection drafts or circulation of dust within the room.

The floor surface temperature required is usually quite low and very close to the actual room temperature and always below 29ºC in occupied areas to achieve an acceptable degree of comfort.

It is essential however, that floor coverings do not provide too great a degree of insulation or the heat in the UFH system may be able to raise the room temperature to its design level. The basic operation of an under-floor heating system is pipe embedded within a concrete screed with warm water circulating through the pipe work allowing for the gradual heating of the screed and eventual emitting of heat from the floor into the room. The heat is concentrated where it is most needed for human comfort and energy efficiency.

It is quite common to have a mixed system in one building where under-floor heating is used throughout the ground floor and radiators are used in the upper floors / bedroom areas, where only sporadic heat is required. Both systems can be operated off one boiler, but will need different time controls due to the different response times. The only exception to this is where UFH is required for a single room. In this case we have a special pump / control unit available which allows such a circuit to be connected to a radiator heating system.
