What does this mean if I want to replace an old Laars boiler?

In September 2010 Zodiac Pool Care merged with and into Zodiac Pool Systems, Inc. (formerly Jandy Pool Products). The Laars Jandy range has now been superceded by the LRZ range which are still manufactured in the same factory. Without getting too complicated if you want a replacement for your LAARS boiler then you'll want a Zodiac Legacy LRZ, the spec and build quality is pretty much the same as its always been, however there are some differences in the layout and size of the Zodiac Legacy LRZ boilers, which mean its not a straight like for like swap anymore. For most "gas safe" fitters this shouldn't be an issue but you may made need to check dimensions since LRZ Zodiac Legacy boilers may be larger and not fit into what might be a tight space.

We've left our LAARS information below for now, but to reach the Zodiac Legacy LRZ pool heaters scroll to the bottom of the page.
