Everybody can benefit from free energy!

Energy that comes from the use of heat pumps is classified as renewable energy using the solar heat stored in the ground, rock, lakes and air. Use of heat pumps represent the most economical method of heating because the amount of energy delivered is up to or above five times more than used to operate the system.

Using heat pumps in combination with a surface mounted underfloor heating system provides the ultimate comfort at all times and at affortable cost.

Temperatures in the Medtiterranean area during periods when heating is needed are very favourable for Air to Water heat pumps delivering up to five times or more the energy used. The truth is that the award winning IVT AirX air to water heat pump is more efficient than a geothermal heat pump if used in the Mediterranean area! Just look outside your window and the energy is there in the air free of charge and available for everybody

Heat your home using heat pumps and save up to 70% of your heating cost! Docking an Air to Water heat pump to your existing heating system and save money and the environment making use of the free energy!
It’s amazing, but true. We know, because we’ve already been using heat pump technology in Sweden for over 30 years

Why choose an air/water heat pump?

Here are the two most obvious reasons

The first is financial. An air/water heat pump makes heating your home and hot water much cheaper. You can reduce your heating costs by up to 70%, although the exact figure depends on several factors such as where you live, the size of your house and whether or not you use the cooling function. Your initial investment is relatively low since an air/ water heat pump, unlike a ground source heat pump, does not require any geothermal drilling. And the efficiency of IVT’s heat pumps (they have an especially high operating range) positively impacts the speed with which you recover your investment. With energy prices continually rising, you’re unlikely to regret your decision. In fact, you’ll start enjoying savings from the first month.

The second reason for choosing an air/water heat pump is that it’s so environmentally-friendly. By merely upgrading naturally occurring energy from the air outside to heat your home and hot water, it leads to much lower CO2 emissions than any traditional fossil-fuel based heating system.

How do you get heat from cold air?

Air/water heat pumps utilise the heat energy of the outside air.

The heat pumps are designed for outside placement and transform an existing radiator system into an excellent, complete heating system.


houseHeat pump technology is actually based on a very simple, well-known principle. It works in a similar way to any domestic refrigerator, using a vapour compression cycle.

The main components in the heat pump are the compressor, the expansion valve and two heat exchangers (an evaporator and a condenser).

A fan draws the outdoor air into the heat pump where it meets the evaporator. This is connected in a closed system containing a refrigerant that can turn into gas at very low temperatures. When the outdoor air hits the evaporator the refrigerant will turn into gas.

Then, using a compressor, the gas reaches a high enough temperature to be transferred in the condensor to the house’s heating system. At the same time the refrigerant reverts to liquid form, ready to turn into gas once more and to collect new heat.

Using an inverter-driven heat pump compressor, the system can be regulated so that heat output matches the exact capacity required at any given time. This means the heat pump will only consume the exact energy needed, making it highly efficient.

In the summer, the refrigeration circuit is capable of operating in reverse to provide cooling on demand.

Four good reasons to choose a heat pump

The heat pump technology has, since its introduction during the 1970s, steadly increased its market share substituting the traditional heat sources like oil- and gas furnaces. Despite the fact that there are different kinds of heat pumps the technical fundamentals are the same e.g., stored sun energy in rock, water and air are transformed into heat.

1. Simplicity in heating your home

There are many methods available to heat your home. Some people still use their oil, gas or electrical boilers. The problem with these types of heating Is that it is expensive, and will certainly become even more expensive, in the future as prices will be increased and higher taxes levied on fossil fuels. Neither are any of these alternatives environmentally friendly. To choose a heat pump with high SCOP will results in both energy efficiency and simplicity. No need for filling up fuel and the only thing you need to do is.setting the room- and hot water temperatures.


2. Reduced heating costs up to 70%

As your heat pump utilzes free sun energy when heating your home, your investment is, in principal, profitable from the first day. In comparison with for instance heating using oil, gas or electricity your monthly heating bill is drastically reduced. Depending on the characteristics of your house and which heating method is used for cost comparison, your heating- and hot water costs can be reduced by as much 70%! In a few years time your heat pump has paid itself as it is saving more money for you than the investment made for the system and its installation.

3. Your house increases in value

Through your investment in a heat pump you do not only benefit greatly as long as you live in the house, but also when you sell it.There is no risk that the heat disappears as new sun energy is stored  which can be used by the heat pump. A high quality heat pump has a life span of approximately 20 years and it is quite common that they continue to work even longer.


4. Environmentally friendly

Your heat pump uses stored  sun energy from its surroundings. Through efficient low energy technology it returns up to five times, or more the energy it uses. In the form of pleasant heat for your house. In addtion the IVT heat pumps are the only ones that manage to meet the very tough and stringent quality- and environmental demands required to be honoured with the Swan certification. Read More…

What is a heat pump and how does it work?
A heat pump is an electrical device that extracts heat from one place and transfers it to another. The heat pump is not a new technology; it has been used in Sweden and around the world for decades. Refrigerators and air conditioners are both common examples of heat pumps.
Heat pumps transfer heat by circulating a substance called a refrigerant through a cycle of alternating evaporation and condensation A compressor pumps the refrigerant between two heat exchangers. In one heat exchanger, the evaporator, the refrigerant is evaporated at low pressure and absorbs heat from its surroundings. The refrigerant is then compressed en route to the heat exchanger, the condenser, where it condenses at high pressure. At this point, it releases the heat it absorbed earlier in the cycle.

How often is service needed?
In order to qualify for the favurable Warranties a yearly service visit by a certified technician is required.

Can it be docked to solar heating?
Yes, the indoor module is equipped with a solar coil that can be connected to solar panels. A solar modul incorprorates the solar panels to the control system which is part of the indoor module.
