During the past decades in Greece the most widely used method for space heating was oil burners in conjuction with steel radiators. Nowadays the need for eliminating emissions and the energy cost forces plenty of building owners to consider all the available technology alternatives. Doing so they come across with the following major questions:

«What is indeed a Heat Pump?»
As implied by the term, a heat pump doesn’t locally generate heat but rather utilizes an electric refrigerant unit in order to pump heat and deliver the energy from external air to the inner space during the Winter, while inverting the process during Summertime. The specific technology along with inverter operation achieves major energy efficiency and emits no emissions locally.

«Nothing is compared to burner heating!»
It’s a fact that the heating we were all used to, delivered by the burners in high temperatures towards the radiators was full of instant warmth and comfort. However our time urgently demands for modern solutions to the critical problem of environmental deterioration and we must adopt to accomplish a more sustainable future. A heat pump efficiently operates by delivering hot water to a maximum of 60^οC and can be combined with conventional radiators, properly dimensioned to fulfill thermal need at these decreased temperatures.

«Does the electricity that I will pay offer me?»
Thanks to the inverter operation and the technology of “pumping heat” the cost for space heating is significantly decreased compared to the equivalent amount needed with a burner system. Moreover the fact that is electrically driven offers the potential of exploiting a photovoltaic system under Net Metering mode totally eliminating the cost of heating and cooling. Finally the owner is no longer obliged to constantly refill with fuels since the system is at all times connected to mains supply ready to operate.

«Can I also utilize space cooling?»
Every modern heat pump is also capable of delivering space cooling during summer. Major requirements for cooling operation are the installation of fan coils (visible or concealed) and pipework strongly insulated to avoid condensation.

«How much does a Heat Pump cost?»
The initial capital required for a heat pump is increased compared to an equivalent burner system (2-3 time overcharge). Given the energy efficiency and energy cost reduction, the specific investment is depreciated within 3-4 years.

«Where should it be installed?»
As far as the installation is concerned, it’s a process fast and simple. A heat pump doesn’t require a special machine room, since the exterior unit can even be placed at the balcony of an apartment. The only requirement is to be freely in contact with the environment in order to transfer heat unobstructed with external air.

Entropy’s team is daily called for answers to a series of relevant doubts that emerge during the initial selection or the replacement of heating / cooling systems. Our engineers and technicians are constantly willing to advise on such matters any owner that is eager to exploit the best choice offered by modern technology.
