Terraced houses
Heat pumps for terraced houses
Terraces are heated with heat pumps every week. The main question is usually where the outdoor unit goes — here's how it works.

Terraced houses are very commonly fitted with heat pumps, despite a reputation for being tricky. They're often smaller, so the system size and cost sit at the lower end. The main consideration is outdoor space for the unit, since terraces typically have a small rear yard rather than a wide garden.
What matters most for terraces
- Unit placement. A rear yard, side return or even a wall-mounted bracket usually works. Modern units are compact.
- Solid walls. Older terraces often have solid walls, which lose more heat — insulation may be recommended, and it lowers running costs.
- Radiators. A few may need upsizing; many terraces keep most of theirs.
