Purchased a Daalderop Close-In Boily in 2011. Used to full satisfaction for two years. Then the boiler started to leak. Fortunately it was covered by the warranty and a new one was delivered. This new one is now leaking again. Daalderop, donderop. It is that I have to indicate one star, otherwise the review will not be posted, but they do not deserve any star from me.
