The Laddomat 11-30 is a ‘loading unit’ for automatic biomass boilers and stoves up to 30kw rating. The unit comprises a circulating pump, 3 way thermostatic valve and 3 isolating valves. Its function is to circulate between the boiler/stove and the accumulator tank, to stratify the accumulator with high temperature layering from the top downwards and to maintain a high return temperature to the appliance, preventing condensation. Fittings are 22mm compression and standard opening temperature is 63^oC. Other temperature cartridges are available.

The Laddomat 21-60 is a ‘loading unit’ for batch fed or automatic biomass boilers and stoves up to 60kw rating. The unit comprises a circulating pump, 3 way thermostatic valve, a bypass valve (for gravity circulation) and 3 isolating valves. Its function is to circulate between the boiler/stove and the accumulator tank, to stratify the accumulator with high temperature layering from the top downwards and to maintain a high return temperature to the appliance, preventing condensation. In the event of power or pump failure, gravity circulation is enabled. The unit is supplied with a rigid insulating jacket. Fittings are 28mm compression and standard opening temperature is 72^oC. Other temperature cartridges are available.

The Laddomat 21-100 is a ‘loading unit’ for batch fed or automatic biomass boilers from 60kw to 120kw rating. The unit comprises a circulating pump, 3 way thermostatic valve, a bypass valve (for gravity circulation) and 3 isolating valves. Its function is to circulate between the boiler and the accumulator tank, to stratify the accumulator with high temperature layering from the top downwards and to maintain a high return temperature to the boiler, preventing condensation. In the event of power or pump failure, gravity circulation is enabled. Fittings are 1 ¼” BSP female and standard opening temperature is 72^oC. Other temperature cartridges are available.

The Laddomat flue thermostat is a thermostat to control a Laddomat loading unit when used with a batch fed biomass boiler or stove. The probe of the capillary wire is clipped externally to a single walled flue outlet from the appliance. The unit allows the boiler/stove to achieve working temperature before circulation starts and prevents unnecessary circulation when the firing cycle is completed. Temperature range 50-300^oC.

The Thermomatic K is a motorised valve controller that regulates flow temperature from the accumulator tank to the heating system by the operation of a 3 way valve or 4 way bivalent valve. Flow temperature is monitored by a probe that is clipped externally to the flow pipe after the mixing valve. If used with a 3 way valve, return water is blended with high temperature flow from the top of the accumulator to produce the desired flow temperature, set by a dial knob in the range 30-90 deg C. If used with a 4 way bivalent valve, flow is taken from two points on the accumulator and if the desired flow temperature cannot be obtained drawing from the lower port on the tank flow from the upper port is blended. If flow from the lower port exceeds the desired temperature return water is blended.
