Thanks Stuart and Ziffius. I really prefer a fixed marine a/c. I also have a local quote of ?5k for a 12000 unit, excluding installation and 18% VAT. Horridly expensive for a little piddly unit when considering ?5k bought me a 14 KW domestic VRV with 3 air handlers, installation, commissioning and tax paid!
Why are these marine units so ridiculously expensive?
