From Stuart Hubbard, Quarff, Shetland, UK
Smith writes that she was unable to find a washing machine that took warm water from the domestic system. The fact that washing machines need high-pressure water used to mean there was no option but to connect them to the cold water supply. Many houses now have high-pressure hot water systems. If her solar panels deliver high-pressure water, she could supply the washing machine through a thermostatic mixing valve – although these are not cheap.
