Long popular for bathrooms, underfloor heating makes a great option for other rooms too. It works by gently warming your room from the floor upwards, resulting in the perfect spread of heat. Underfloor heating also runs at lower temperatures than traditional radiators making it more efficient resulting in lower running costs.

‘It is possible to have underfloor heating systems for several different rooms (zones), with each having their own separately controlled programmable room thermostat,’ explains Danny Zikic from Ecomaxx. ‘This means that you can simply switch off the room that you don’t use, thereby lowering the heating cost.’

Today, the recommended underfloor heating system is the dry or electric system in which an electric conductor (copper cable, thermal mat, copper mesh or aluminium tape) is laid beneath the floor with a thermostat that controls the temperature placed on the wall. Installation is simple and swift. ‘And it can be installed under any flooring – tile, stone, wood, laminate or carpet,’ says Louise Cachia from Alternative Technologies.

There are two options for the current that runs through the conductor – high voltage (220-240V) and low.

High uses copper cables which are then plugged into a regular wall socket; there is also no need for transformers to convert the high voltage alternating current (AC) from the grid to lower voltage direct current (DC). Disadvantages are the high temperature of the cables and copper oxidation.

Low voltage direct current run through a conductor is safer than high, and results in a lower consumption of electricity. However, transformers are needed to convert the AC to DC and these must be situated in a dry, ventilated environment (so for a bathroom, they would need to be in an outside the space in the corridor or a storage cupboard).

Underfloor heating gently warms your room from the floor upwards, resulting in the perfect spread of heat, creating a comfortable environment for all. All electric underfloor heating systems run at temperatures lower than traditional radiators, making them more efficient, with lower running costs. It can work divided in several independent heating zones (rooms), separately controlled by programmable room thermostats and can be installed under any type of flooring, requiring little to no maintenance.

Air-Source heat pump is the technical name for an air-conditioning unit that sits outside an apartment or house absorbing heat from the outside air (even when temperatures are as low as -15C) and releasing into the inside at a higher temperature.

It does so using a refrigerant (a volatile liquid) which is compressed and passed through a very small opening (as happens with a spray) into the external radiator of the air-conditioner. This results in the refrigerant’s temperature dropping, so allowing it to absorb heat from the outside air. The refrigerant then continues to the indoor radiator (called the fan-coil unit) where it releases this heat into the indoor space to be heated.

Air-source heat pumps can be used to heat radiators and underfloor heating systems as well as give hot water.

A renewable energy source to generate heat for radiator circuits, underfloor heating, DHW, swimming pools, and even cooling – while substantially increasing your savings. The ecoGEO heat pump systems are simple, compact, fast, and easily installed, do not produce any flame or smoke, and have little or no visual impact on your home. Fireplace Malta
