Standard design Central Heating (CH) Heat Exchangers

INSTANTANEOUS CENTRAL HEATING HEAT EXCHANGERS (SYSTEM BREAK)

Central Heating system breaks tend to be used to separate and protect a new boiler or Primary heat source from an old heating circuit that may leave dirt or debris in the boiler.

Most Central Heating design duties using a system break tend to be the same or very similar for 90% of the time with the Primary hot water supplied from the boiler at 85 oC and the secondary radiator heating circuit designed to raise the water from 70 oC to 82 oC in line with the original Delta t design of the radiators installed. With this in mind AEL have standardised all the technical information needed with prices below based on your heating systems demand and KW available from your boiler or heat source.

You will see technical information and prices for each central heating duty from 30KW up to 1000KW as a standard item that can be purchased online or direct with the sales office with the facility to enquire about bespoke designs or to ask general technical questions specific to your installation.

Central Heating Plate Heat Exchangers (System breaks) can be supplied as a Plate / Gasket unit or supplied as a Brazed Plate unit. In practice both types of heat exchanger transfers energy from hot or cold fluid and ensures that the Primary circuit does not mix with the Secondary circuit therefore creating two completely independent separate heating or cooling circuits.

Plate & Gasket Heat Exchangers are built with high quality usually EPDM or Nitrile gaskets which are designed to seal a bank of stainless steel plates together. Plates can easily be removed for cleaning, expansion to increase output or to replace with a new bank within the existing frame reducing high maintenance costs. Brazed Plate Heat Exchangers are commonly used in low demand central heating systems. The stainless steel plate and copper brazing construction means that they resistant to corrosion but fixed in as much as the plates are not accessible to expand capacity or replace.
