Product details

The COMPACT series from SIGMAR marine offers innovative water heaters of 20 to 40 liters, developed specifically for use in recreational boating. The solid 1.5 mm thick stainless steel tank is argon gas-shielded welded. Due to their design, COMPACT boilers are particularly suitable for installation on flat surfaces/ bulkheads. They feature a thermostat and a safety/check valve. The water heater uses the excess heat produced by the engine cooling circuit, shore power supply or energy from a generator. Using excess heat is very economical: water is permanently heated and the excellent insulation of the boiler keeps it hot for a long time. Each boiler has an integrated safety valve which opens for protection from a pressure of 4 bar (58 psi). The hoses can be connected via ½" fittings/nozzles (the connection nozzles are not included).
Heater:
  • B0 20 UC: 800W
  • B0 22 UC: 800W
  • B0 30 UC: 800W
  • B0 40 UC: 800W

To replace an old model like C-WARM, it is necessary to provide pipe extensions. The inlets and outlets are not arranged in the same way.

already installed 2 years ago
The boiler does what it is supposed to do absolutely reliably, would buy it again, and installation was easy

Boiler replacement for Beneteau 473
Replaced the quick 43 litres boiler with this 30 liter model.
It was easier to mount the new one then to remove the old one.

I miss some connection parts like 12" tube couplings to connect to the engine and 12" F-F couplings to connect the hot and cold water tubes.
I also recommend to order the mixing valve to keep the temperature under control when the water is heated by the engine.
