The Bosch Compress Hybrid 3400AWS allows the

integration of the high efficiency heat pump with the

benefits of a gas combi boiler. Dependant on climate

conditions, the system can operate to be most

effective using either the boiler or heat pump when it

will be most favorable to do so.

The system can be set up to run the boiler and heat

pump at the same time, or each appliance can be

used individually if required.

It is also possible to adjust the weighting of the

system in favour of electricity or gas if the price of

fuels change.
