Very interesting, LucMan. Might explain what I have been hearing in my locality and why few suppliers of hot water systems are even interested in selling heat pumps. The same thing applies to solar thermal though it appears to be slightly more fashionable than heat pumps. Several people have said to me, “don’t install solar thermal – it only lasts 6 years”.
Could it also have something to do with water quality? It’s not good here. The source is ground water with high levels of iron and magnesium.
