- Is there space for a trench or bore hole to be dug just outside your home? And is the ground suitable for digging?
- What kind of heating fuel would your ground source heat pump be replacing? If it's electricity, oil or liquid petroleum gas and you live in an area with no gas supply, then the payback will be more favourable.
- Do you need a back-up heating system for additional space or water heating? This will depend on your overall heating needs, compared to the size of system that you install.
- Is your home still being built? If so, it will be cheaper to install the ground source heat pump and underfloor heating system at the construction stage rather than when construction is complete.
