Coil heat exchangers are a reliable solution for providing hot water, compatible with a single heat source such as gas, pellet, or oil boilers, and water-jacket fireplaces. Water is efficiently heated by a spiral coil positioned in the lower or upper sections of the tank.

Enamelled heat exchangers are available in multiple variants:

• BTm: Maxi coil optimized for heat pumps
• BT-11: Two coils for solar panels and central heating boilers
• BT-01: Single coil
• BT-00: Coil-free design
