Product detailed description

- model Hewalex OKC 200 L, 300 L, 400 L and 500 L - with 2 heat exchangers, including insulation

is designed for heating hot water in a 2-circuit system consisting of a solar system and a boiler
effective corrosion protection using the enamelled surface Crystal Enamel®
optimal relation of energy efficiency to purchase and operating costs
magnesium anode for additional protection of internal surfaces
reduction of heat losses to a minimum using rigid polyurethane foam ThermoGen®
hard plastic casing, easy to keep clean
built-in thermometer in the casing allows water temperature reading and monitoring of the tank operation
6/4” inlet allows installation of an electric heater (for emergency water heating)
adjusting tools for leveling the heater on the floor

The lower coil is connected to the solar thermal system and the upper coil to a traditional heat source, such as a hot water boiler.

Another heat source can be an electric heater - its connection is enabled by a separate pipe fitting 6/4”. The tank is characterized by low heat loss due to polyurethane foam used as insulation (thickness 50 mm). Energy efficiency class "C" indicates a very high standard in this category and size of heaters. At the same time, it allows maintaining an optimal ratio of energy efficiency to purchase and operating costs.

The outer casing is made of hard plastic in a grey color.

It is therefore more resistant to dirt and mechanical damage.

The internal surfaces are made of steel and covered with a ceramic enamel that protects them against corrosion.

The magnesium anode is a standard heater fitting and provides additional protection.

The heater can be placed directly on the floor and precisely levelled using adjusting tools (feet).

tradition and modernity

More than 30 years of experience – from a vision to a leading manufacturer with a strong position on European markets

Hewalex was founded 30 years ago, long before the renewable energy market began to develop in Poland. We had a vision that in the future traditional fuel should give way to clean, renewable energy – for economic reasons as well as to protect the environment. From the very beginning our priority was to manufacture high-quality, efficient solar thermal collectors, which were at first shipped to foreign markets in Western Europe. Today we have a specialised team of almost 200 qualified people and the experience we have gained over the years. We take part in various innovative investments and contribute to international research and development projects concerning, for example, solar cooling of buildings.

A few facts about us

30 years of experience
The manufacturer of solar collectors and solar equipment with the longest history in Poland
A leading manufacturer of solar thermal collectors and heat pumps
High technical standards of products, confirmed by a presence on more than 40 European markets
Research, development and design facilities, also suitable for bespoke projects
Participation in the GREENEVO project, which supports innovative Polish companies on foreign markets
Participation in international research and development projects
Cooperation and partnership with many respected construction companies, as well as designers and trading companies
Customer care services and good warranty terms
ISO 9001 quality management system
Audits to national standards, e.g. French or North American

Through the Slovak Innovation and Energy Agency’s national projects Zelená domácnostiam (a Slovak subsidy programme), family houses and apartment buildings will be able to obtain support for installing small systems that use renewable energy sources. The support may only be used for equipment that meets the technical conditions and is registered.

HEWALEX collectors are eligible equipment, and you can apply
for a subsidy. More information can be found HERE.
