A well chosen solar hot water system or a heat pump may cost more to begin with, but for most homes they’ll be significantly cheaper to run than a conventional electric or gas system.

What are the disadvantages of solar hot water?
- Compared to photovoltaic panels, solar thermal panels only heat water.
