Tranquility THW Geothermal Boiler

The Tranquility High Temperature geothermal boiler is ideal for use in a domestic application for heating and domestic hot water production and comes in 8, 10 and 12KW models in either 1ph (8 & 10KW) or 3ph (all models) electrical supply.

The THW has connections for the source water loop, the heating system and the hot water cylinder. Hot water heating takes priority as this takes a shorter period to satisfy.

The hot water is stored in an indirect cylinder and we supply these in capacities ranging from 150 to 500 litres. Models from 215 litres upwards can have additional solar coils.

The heating water is stored in a buffer tank which is kept at a temperature dependant upon the outside air temperature in order to match the heating system output to the demand.

The controller is menu driven and easy to use with different temperature settings for the buffer tank and the hot water cylinder. The buffer tank has a heating compensation system as shown below.

The controller has a fault indication system and this is shown above.
