Support with your heat pump after installation 

The part of the heat pump that sits outside is roughly 1m x 1m x 2m (or to help you visualise - the size of a moped). It needs a space of around a meter in front and to each side to breathe.

Inside you need space for a hot water tank - 2m x 1m x 1m (the size of a modern fridge freezer), on the ground or first floor of your home (the closer to the heat pump the better).

The cylinder can also be installed in a garage, outdoors in a purpose-built store, or in the loft, but this may decrease efficiency (it takes more energy to heat the water when the cylinder is exposed to the cold).

A Turbo heat pump runs at a higher temperature and requires less plumbing changes, making it cheaper to install but more expensive to run. Whereas an Eco heat pump runs at a lower temperature and requires for more (or larger) radiators to be installed – costing a bit more to install, but less to run.
