Top job - much better than Franke original
Solidly made. Easy to install. Replaceable hoses and can be descaled. All of this is thoughtful in a way that Franke's original simply wasn't. The original was bloody expensive and the performance fell off a cliff over five years. The overflow valve had to be replaced three times and the tank couldn't be descaled. Annoying! Flow slowed to a trickle despite two Franke filters a year at forty five quid a pop. Additional PRV had to be fitted to prevent constant drip into tundish. New tundish as well, twice.
This product in comparison feels simple, classy, took less than an hour to get in even with a spot of remade pipework - the regs about overflows have changed. And: instant success. Flow is back to very usable rate and is properly scalding. I recommend this product!
