Now you know what kit you will need, it's time to think about where it will all go. This will be specific to your home layout, but here are the kinds of things that will be taken into account:
- Availability of space.
- The length and complexity of the route for pipework between the external unit and internal components.
- The length of pipework from the cylinder (or other heat store) to the places you need hot water. A long pipe run will mean a longer wait for hot water to arrive at your taps, and wasted water and energy as it runs through.
- The length and complexity of the electric cable run between your fusebox and the heat pump and cylinder.
- Availability of external drainage for the expansion vessels to overflow into, if necessary.
The ultimate position is likely to involve a trade-off between these factors. As always, your installer will be able to advise you.
