Stones Posted July 9, 2016 Share Posted July 9, 2016 One of the options flagged by my plumber when discussing my heating and DHW was installing a Mitsubishi Ecodan and pre-plumbed cylinder https://heating.mitsubishielectric.co.uk/Products/Pages/Monobloc_Pre_Plumbed_Standard_Cylinders.aspx as a simple all in one solution. Sounds and looks great at first glance, a nice neat and easy solution, both heating and DHW from the same cylinder. The red flag for me was when he said the cylinder operates at 60C, which to my mind either means significantly reduced COP in respect of the ASHP, or that electric back up (immersion) is being used to top up the cylinder all the time. TBH, I can't really see any advantages to using such a set up, other than speed and ease of installation. Comments? Link to comment Share on other sites More sharing options...
PeterW Posted July 9, 2016 Share Posted July 9, 2016 Wait till he gives you the bill ...!! They were about £6k IIRC for the 11kw Ecodan and a 250 litre UVC Link to comment Share on other sites More sharing options...
Guest Alphonsox Posted July 9, 2016 Share Posted July 9, 2016 We briefly looked at these as a solution and came to the same conclusion as Peter - Just too expensive http://www.get-direct.com/mitsubishi-ecodan-package---85kw-air-source-heat-pump-pack-with-210-ltr-cylinder-199-p.asp Link to comment Share on other sites More sharing options...
Stones Posted July 9, 2016 Author Share Posted July 9, 2016 At that sort of money, it's a non starter. Thanks for the input. Link to comment Share on other sites More sharing options...
jack Posted July 10, 2016 Share Posted July 10, 2016 Same here. We have a Panasonic monobloc. The unit itself is very high performance and good value. But as soon as you get into accessories it gets eye-watering! Pre-plumbed cylinders were more than twice the cost of a much better insulated equivalent from a third party (and there was no way of getting better insulation on the Panasonic one).
