Laddomat 21 is a charging unit for a solid fuel boiler to a storage tank with hot water heater and mixing valve for the heating system.

Laddomat 21 enables the boiler to attain a proper boiler working temperature in a very short time.

• Charging is continued by means of a slow flow of hot water.
• During the final part the burn-out the Laddomat 21 charges the storage tank fully due to the unique thermal valve, which closes the bypass opening completely.
• When the fire has gone out, Laddomat makes use of the remaining heat in the boiler and ember by the self-circulation of hot water from the top of the boiler into the storage tank. Energy is stored in the tank instead of being lost through the chimney.
• In the event of a power failure Laddomat 21 starts charging the con-tainer immediately by self-circulation.

The same happens if the pump breaks down. Reverse circulation is prevented during periods of non-firing, which means almost no loss of heat.

	1. RS 25-6-3 circulating pump
	2. Return temperature indicator
	3. Heating water temperature indicator
	4. Mixed water temperature indicator
	5. 1 Ľ “ IG ball valve
	6. Thermostatic valve
	7. Automatic valve for regulation of gravitation circle
	8. Deposit collector
	9. Exit for filling out

Laddomat 21 works automatically on the condition that pump switches on / off automatically.

Laddomat 21 works efficiently during all stages of the boiler operation.
