Low temperature heating and cooling with solar thermal energy
The Equideas capillary mat heating and cooling system is the most comfortable and energy efficient system on the market.
For more than 15 years, conventional HVAC systems (heating, ventilating and airconditioning) are being replaced by the ecological and climate efficient technology of capillary tube mats for heating and cooling. Water filled capillary mats are used for the implementation in ceilings, floors and walls.
The capillary tubes are made of polypropylene, with an outer diameter of about 4 millimeters, which run in a narrower distance than convetional floor-heating pipes. Because of it’s large exchange surface, large amount of energy can be transferred even at low temperature differences between the room air and the room surfaces. By integrating the capillary tube mats directly into the floor, ceiling or wall the reaction of the system is very fast, and within a few minutes the required surface temperature has been reached. Even if implemented into light concrete, cap mats need only need ¼ of the time to heat up than conventional systems which saves you up to 40 % of energy.

Capillary tube mat systems for heating and cooling
The Equideas capillary tubes are a closed system that is filled only once is, so you need not be afraid of calcification or other impuritie problems. The extreme flat system of the capillary tube mats are not only perfect for the implementation in ceilings, floors and walls of new buildings but also to refurbish an existing installation. After installation, the heating / cooling system vanishes completely from your field of vision, leaving only the warmth or the refreshing cool that let you think of a heating or air conditioning system.
- Capillary tube mats can be integrated in floors, ceilings and walls
- Heat in Winter time - cooling in Summer time
- Ideal for solar thermal system with air to water heat pump and solar hot water storage tank
- Healthy indoor climate, ideal for kids and allergy sufferers
- Space saving - invisible
- Fast reaction of the system

Solar thermal flat plate collector
The Citrin solar thermal flat plate collectors consist of a dark flat-plate absorber of solar energy, a special safety glass that ensures a reliable protection and an optimal use of solar energy through its inner prismatic surface, a heat-transport fluid (antifreeze) flowing through tubes to remove heat from the absorber, and a heat insulating backing.

Citrin solar thermal storage tank
The hot heat transfer fluid transports the heat generated, with the help of a circulation pump, from the collector into the heat exchanger of the solar hot water storage tank, runs through it and returns as liquid cooled back to the solar flat plate collector and closes the circuit.
The heat exchanger increases the temperature of the water in the solar hot water storage tank. The now hot water in the upper part of the hot water tank will run through the capillary tube mat system, and heats or cools floors, walls or ceilings before it comes back into the solar hot water storage tank where it is heated up again.
For the security of the collector circuit the solar storage tank includes security fittings and an expansion tank.
The solar controller switches on the circulation pump when necessary comparing the collector and storage temperature.
- Upright smart hot water solar storage tank
- Legionela safe potable water is warmed by heat transfer
- Flexible stainless steel tube for maximum protection against calcification
- Low-flow solar charging system for high efficiency
- Operating temperatures of up to 95 ° possible - higher energy storage
- CFC-free polyurethane soft foam insulation 100mm

Air source heat pump
In case the solar energy is not sufficient for our system, which barely happens in the Canary Islands, we have decided to use an air source heat pump, that works highly efficient thanks to our year round warm temperatures. The air source heat pump heats the upper part of our hot water tank to the desired tempertature and guarantees the operation of the installation even in a worst case situation.
Air source heat pumps are energy efficient and can provide up to 4 times the amount of energy they consume which means that a modern airsource heat pump that consumes 1 Kw produces up to 4 Kw of heating power!
How does an air source heat pump work?
The air source heat pump is removing heat from the air and redistributes this heat into the desired location through radiators or in our case an underfloor heating system.
1. Evaporation
The coolant circulating in the air source heat pump system collects heat from the air and this process causes the coolant to evaporate and change to a gaseous state.
2. Compression
The air source heat pump's compressor rapidly compresses the coolant, which is now in a gaseous state and several degrees warmer. Thanks to the laws of physics behind the compression process, which cause the temperature of the compression medium with increases in pressure, the compression elevates the otherwise low potential heat of the coolant to a higher level of about 80°C.
3. Condensation
Using a second heat exchanger, the heat from the heated coolant is transferred to the water circulating through the radiators. This causes the coolant to drop in temperature and condense back into a liquid state. The radiators distribute the heat provided into the heated areas. The chilled water in the heat loop then travels back into the second heat exchanger, where it is heated again.
4. Expansion
By passing through the expansion valve, the coolant travels back to the first heat exchanger, where it is once again heated.
