Heat for you and relief for the environment

Are you annoyed as well about the high energy prices? Are you worried about the continuing shortage of resources? Would you like to contribute to protect the climate, as well? Then you can set an example for clean energy that nature delivers for free. Because the sun does not only send us light but heat as well. Every day. Even when the sky is cloudy. The potential for the use of solar energy is inexhaustible and a real alternative to fossil energies which are slowly running out. Our solar thermal systems convert heat radiation into directly usable energy, for instance for hot water, for your heater or swimming pool heating. And the best is that your commitment for renewable energy sources will be rewarded. No matter if a new house is built or an old one retrofitted, more and more people put their trust in the power of the sun when it comes their energy supply. The number of roof areas that are equipped with solar panels is ever increasing and equally the relief to the environment of up to a ton of CO2 per household. Make use of our competent advisers and enjoy the good feeling to be more independent of traditional energy sources. The future has begun!

Solar Thermal Energy – A Simple Concept with Great Efficiency

A hot water collector “catches” the solar radiation via a specially coated absorber that heats the solar liquid in the collector through a tube system. The heated liquid is then transported to the storage tank through a controlled pump system. There, the heat is transferred by means of a heat exchanger to the water that is now at your disposal as hot drinking water. Alternatively you can choose a combined storage tank that additionally produces heat for your central heating system. If necessary you can integrate an additional heat exchanger for swimming pool water into the system. No matter how you decide, the perfectly tuned components of our systems provide you with the highest efficiency and cover up to 70% of your hot water demand per year through solar thermal energy.

The Collector – Hightech for Maximum Performance

This high performance hot water collector is easily fitted vertically or horizontally into various roof structures. The casing is self-supporting and consists of non-corroding aluminium. The precious interior is protected through solar security glass. The surface is anti-reflecting and fits harmoniously into the aluminium frame. The glass is protected against hail and other weather conditions and provides all around security. And to prevent unnecessary energy loss the collector is equipped with an optimized heat insulation.

The AS Solar vacuum tube collectors are industrially manufactured serial products. They impress through their outstanding design, professional manufacturing, high quality and high energy yields as well as a fair price-performance ratio. The first-class materials ensure an unproblematic operation over a long period of time. In order to increase the efficiency of the vacuum tubes there is a highly reflecting, weatherproof CPC-mirror behind the vacuum tubes that ensures that direct and diffuse sun light hits the absorber even under unfavourable radiation angles. The energy yield increases considerably.

The Right Solution for Every Roof

Our solar systems provide the optimal solution for every customer request and every roof. Beside the mere functionality esthetics play a central role because our systems do not only produce energy but also present a harmonious whole with the building’s architecture. Whatever system you might choose, we guarantee perfect functionality and a highest degree of safety in every kind of weather.

On-Roof Mounting

With this version the system can be installed vertically and, with the AS-FK 2.3 and AS-EVK 10, horizontally as well. The installation can be done dependently or independently from the rafter. We offer you for that roof anchors for all common roofing tiles. During the installation the tubes are being led through a vent tile. This version has the advantage that the roof surface area remains intact and that the on-roof mounting method is possible with almost every roof type.

Flat-Roof Mounting

With this version it is also possible to install the system vertically and with the AS-FK 2.3 horizontally. Apart from the easy installation securing the system against wind, storm and snow has the highest priority. By means of specially reinforced safety elements attached to the back lateral forces are absorbed. With this method the entire system is perfectly protected from weather-related damages. Through the sophisticated mounting technology the roof surface area remains intact with the flat-roof mounting method as well. Apart from that there is the possibility to lay the AS-EVK 10 flatly on the roof surface and only turn individual tubes 30° to the South.

In-Roof Mounting (only AS-FK 2.3 and AS-CPC 12/18)

With this method a plastic vat is inserted into the roof under the collectors. This system replaces the conventional roof covering and offers a non-problematic rainwater run-off. In case of the AS-FK 2.3 the collectors can be affixed horizontally.

A Perfect System for Comfortable Warmth

The components of our solar thermal systems are optimally tuned and offer complete solutions in perfection.

The Solar Storage Tank

Optimal hot water generation for a household of up to 5 persons. The tank consists of enamelled steel and is protected against heat loss through its removable insulation.

The Combined Storage Tank

The space saving combined solution for hot water generation and heating support. The fresh water concept ensures a highly hygienic tap water generation. Apart from this innovative solution we also have the tank-in-tank version in our portfolio. The heat insulation keeps any heat loss low.

The Solar Station

The station is equipped with filling and flushing faucets for a perfect start-up and maintenance. The gravity brakes at the primary and secondary circuit prevent any kind of thermal circulation. The system is aired automatically which makes the tedious roof deairing unnecessary.

The Solar Controls (C1 and CPlus are already integrated into the solar station)

Type DeltaSol® C1:
Digital controller for temperature-difference controlling in solar systems for 1 collector field and 1 consumer.
Type  DeltaSol® C PLUS:
Digital controller for temperature-difference controlling in solar systems for 1 collector field and 2 consumer or for East/West collector fields for 1 customer. Also suitable as a controller for heating support with combined storage tanks.
Type DeltaSol® E:
The 7 variable preprogrammed basic systems of the DeltaSol® E allow for the controlling of various large plants. With its 7 relay outputs and 10 sensor inputs a multitude of additional functions and options can be activated.

All controllers are characterized by their perfectly readable, large displays with function control, possible data communication transmission and remote maintenance with the RESOL VBus® which enables the bidirectional communication with the PC or for data logging. Additional advantages are the integrated heat quantity calculator and easy handling.
