Sirena Solar HFD

Automatic emptying system

Stainless steel accumulator

From 27 to 39 kW

Adapted to the ErP regulation

Hybrid (Solar-Gasoil ) condensation solar boiler

The SIRENA SOLAR HFD solar-gasoil hybrid boiler combines, in one single unit, the use ofsolar energy with energy originating from gasoil combustion.

This range of boilers has been adapted to the demands and requirements of the new ErP European Directive in terms of performance and labelling.

This hybrid solar-gasoil boiler harnesses solar radiation to heat a 150 litre tank and supply hot running water at a cost of practically zero, providing there is energy from the sun.

 

Advantages

SOLUTION TO THE CTE REQUIREMENT OF MANAGING SOLAR RADIATION SURPLUSES

The automatic solar panel emptying system that this solar-gasoil hybrid boiler incorporates, makes it impossible for the solar contribution to be greater than the demand. Possible panel deterioration is thus avoided. This is possible without having to install complicated heat evacuation systems or covering the panels.

HIGH HOT RUNNING WATER PRODUCTION

The boiler has a 150 litre solar accumulator, which permits using several consumption points at the same time providing there is accumulated solar energy.

MAXIMUM HARNESSING OF SOLAR ENERGY

A novel booster system increases the capacity to harness solar energy on transferring any surplus energy from the solar accumulator to the support accumulator. Thus, up to 380 litres of running water can be heated.

ENERGY PERFORMANCE

The system incorporates high performance solar panels with exceptional energy harnessing. It also has condensation technology, which permits fuel savings of up to 30% compared with a traditional boiler.

EASY TO INSTALL AND MAINTAIN

It is designed to avoid the use of expansion vessel, steam trap and magnesium anode in the solar circuit, thus making it easy to install and maintain.

SPACE SAVING AND EASY-TO-USE

The AVANTTIA SOLAR H hybrid solar boiler resolves the production of HRW and heating, using 2 possible types of energy, without having to have 2 different appliances.

ELECTRICITY SAVING

From the moment the solar circulation is balanced, the electronic system reduces the electricity consumption by 50%.
