With an average household size of about 2.3 people and a high share of separate houses (over 1,500 dwellings), reliable hot water is essential for everyday life, from long showers after work to running a busy farm or small business.

The local weather station at Erriba records mean daily solar exposure of around 14.10 MJ/m², which works out to roughly 3.9 kWh per square metre per day over the year. That steady sunlight supports both a solar hot water system and a heat pump hot water system, especially when paired with rooftop solar.
