No, heat pumps can be installed into existing properties replacing gas/oil fired boilers or direct electric heaters (I.e. Storage heaters). Often we see that the 'retrofitted' heat pump systems offer the greatest energy savings to inefficient buildings. With all 'retrofit' installations extra emphasis is placed on system design to ensure the equipment is suitable and work efficiently. Thorough room by room heat loss calculations are undertaken, including full appraisal of existing central heating systems.

Not always, it depends on which heat pump is being installed and the condition of your existing equipment. High temperature heat pumps, which provide similar heat output to a conventional fuel boiler, can be connected to existing hot water cylinders. Low temperature heat pumps (With lower water temperatures) require a specialist cylinder with a larger heating coil to provide a energy efficient heat transfer to the stored water. Plus they need a integrated immersion heat (Controlled by the heat pump) for disinfection.

Yes. All the heat pump systems have the ability to be controlled via third party thermostats. The system will modulate its heat output (weather compensated) once it has received a heating demand signal. Griffiths always discuss the 'Pro's & Con's' of using 'Smart' controllers with our specified systems.

On the same principals as a refrigerator, however the system is split into two parts. The indoor unit acts like the cold plate inside a fridge and the outdoor unit acting like the warm pipes on the back. Using a refrigeration cycle, heat is absorbed (from within the room) and transferred to the outdoor unit where it is dissapated.

Yes. There are a number of ways to do this, but they have to be designed into the system from the start. These systems are often referred to as a 'multi-split'.
