HEAT EXCHANGER, Noninsulated

REKA heat exchanger including built-in storing tank with domed end plated made of 4 mm tank plate. The heat exchanger is normally applied if it is not possible - due to large difference in heights - to connect the existing boiler and the solid fuel boiler and this ensure that the expansion tank is placed as high up as necessary.
