SOLAR HEATING SYSTEMS 

COMPACT, "ALL-IN-ONE" SOLAR SYSTEM 

This is an ALL-IN-ONE solar system that uses solar 

thermal energy to heat domestic water. It integrates 

the absorber, the pump-circulated system, and the 

150l tank. It uses a PV-driven circulating pump, 

which means it is a fully autonomous system that 

does not require any external power source.

HOW DOES IT WORK? 

From sunrise till water is hot. 

85º 

STAGE 1 

Solar radiation reaches the 

collector, which concentrates 

the heat that is then 

transferred to the heat 

transfer fluid that circulates 

through the system. 

The selective treatment and 

the shape of the surface, it 

uses a large proportion of 

incident radiation. As it is 

filled with the heat transfer 

fluid, it can use 100% of 

the surface. 

STAGE 2 

The radiation on the surface 

is also received on the PV 

panel, which generates 

the power that drives the 

circulating pump. 

The pump gets the hot fluid 

into the exchanger. 

STAGE 3 

The heat is transferred to 

the tank because the hot 

fluid passes from the pump 

to the exchanger. 

The tank will get hot 

whenever there is sunlight 

up to the top limit set at 

85ºC.

WHERE IS IT INSTALLED? 

It can be adapted to meet different installation needs 

The ALL-IN-ONE solar system can be placed anywhere requiring domestic hot water (homes, campsites, 

community vegetable gardens, country homes and hotels). The ALL-IN-ONE solar system can be placed in 

a wide variety of places, from a pitched roof (either built-in or not) to a flat surface, a garden or a wall.

SOLAR PANEL FOR SWIMMING POOLS 

Heated pool water almost all year round. An efficient, affordable alternative. 

This is one of the most technically efficient, cost-effective applications for swimming pool 

water heating. Your pool season is extended by 2-3 months with this solar panel system, 

as the process involves heating large amounts of water to a relatively low temperature. A 

solution using solar power: a clean, free, inexhaustible power source to keep your pool water 

at just the right temperature. 

FEATURES 

Stainless steel solar collector. 

Collection surface area 2 m² and weight 15 Kg. 

3 hydraulic connections (Ø ¾) for any 

installation configuration. 

Dimensions 2000 x 1000 x 18. 

Sold in batches of 4 units. 

Panels guaranteed for 5 years.

Solar heating 


ADVANTAGES 

It extends the pool season by 2-3 months (at temperatures over 25ºC) 

The system is compatible with other auxiliary pool heating systems. 

Excess heat can be used for domestic hot water production, via a heat exchanger. 

Adaptable to all kinds of pool. The system is connected to the existing filter circuit using a heat exchanger 

or directly, depending on the type of filtering. 

Totally controllable via a central control unit. It enables the pool temperature to be controlled and the 

solar collector system to be switched off when the water reaches the desired temperature. 

A smaller heating surface area is required compared to other systems on the market.

SELECTION GUIDE 

The Drain-Unit selection is determined by the height of the installation. Bear in mind the difference in height 

between the top of the collector array and the bottom part of the Drain-Unit positioning. 

N.b.: less pump power required if the Drain-Unit is installed just above the collector field.

OKFRESH - Fresh Water Station 

Instant hot water whenever you need it 

The Fresh Water Station is a system that guarantees instant hot water whenever it is required, 

at just the right temperature. This system guarantees coverage of your domestic hot water 

needs, avoiding any hygiene or power loss problems connected with domestic hot water storage. 

With its instant hot water principle, Orkli's Fresh Water Station is the ideal system for use in 

homes, residences or sports complexes, and it is perfect for use with renewable energy heating 

installations. It is simple to install and can be easily adapted to the users' requirements.

• Instantaneous domestic hot water production. 

• Stainless steel 90 kW heat exchanger. 

• Domestic hot water production capacity 30 l/min. or 20 l/min. 

(depending on the number of heat exchanger plates). 

• Flow meter activation = 2 l/min. 

• DHW temperature controlled by a thermostatic valve acting on the 

primary circuit's 3-way mixing valve to regulate the heat exchanger 

flow. 

• Ensures a low return temperature of the water in the primary circuit 

(to aid stratification). 

• Connection for an optional DHW circulating system available. 

• The highest temperature is concentrated in the component in the 

lowest location so that the heat is naturally transferred to the top part 

of the heat exchanger, cooling down the hot zone and preventing 

problems with scale.

INDIRECT HEAT EXCHANGE 

SOLAR KIT 

The indirect heat exchange solar kit is designed for centralised solar heating installations with 

distributed back-up power. Each home has an individual back-up power source and its own 

interior distribution circuit supplying domestic water. 

This kit regulates the recirculation inlet to the home from the circuit previously heated by the 

solar collector. If the kit detects that a tap has been turned on and hot water is required, the 

flow to the heat exchanger is opened to preheat the domestic water inlet. When the hot water 

tap is turned off, the 3-way valve opens the bypass again and shuts off the flow to the heat 

exchanger. The shut-off valves allow the central recirculation system to be completely blocked 

off at all the inlets.

SOLAR DHW KIT 

A universal kit for connecting a solar hot water tank to a 

conventional domestic hot water source 

Unit for connection to the auxiliary domestic water heating units installed between the solar 

water tank and this back-up power source, normally an instant water heater or a gas or 

electric water heater. It includes a 3-way valve, which determines whether the water from the 

solar water tank should be conveyed via the back-up power source or can be directly sent on 

for consumption, and a mixing valve regulating the outlet temperature of the domestic hot 

water in the solar heating + conventional back-up system.
