Alde 3020 HE boiler

All connections, both liquid, gas and electricity are located on the long side. This makes it easy to install and service the Compact 3020 HE. The installation dimensions are also minimal as there are three completely clean sides.
Inside the metal casing of the Compact 3020 HE is the gas-powered burner that operates with two power levels depending on the power requirement.
All models of the Compact 3020 HE are equipped with two 230-volt electric elements with a maximum power of 3150 W.
The hot water tank in the boiler is of the storage type and has a volume of over 8 litres of fresh water.
The control of the boiler is managed via a processor on the boiler's circuit board.
The Alde Compact 3020 HE can be connected to the Truma Aventa Comfort AC, thereby achieving full climate automation.
The Compact 3020 HE can be installed virtually anywhere. Either inside the living space, such as in a wardrobe or storage area, or mounted outside in some storage space or in an intermediate floor.
The exhaust outlet and intake air can either occur via a side-mounted flue or a flue mounted on the roof.

Construction:

The Compact 3020 HE consists of three eccentrically mounted pipes, (the heat exchanger, the water jacket for the heating system, and the outer water jacket for hot water).

The two outer pipes with ends and connections are made of stainless steel while the heat exchanger is made of aluminium. 
The heat exchanger is divided into two circular halves. The burner is located in the upper half which constitutes the pre-combustion chamber and in the lower half, the flue gases are expelled.
On the end of the heat exchanger, the burner housing is mounted. This consists of a combustion fan, burner, solenoid valve, and intake/exhaust connection. 
In the water jacket for the heating system, two 230-volt electric elements are mounted.
