I bought Mixergy 300L tank for my Daikin air source heat pump 14kw. Exactly one year after installation the Mixergy tank stopped working with ASHP.
Customer service support for the tank is great but the tank loads of rubbish. I have thrown £2,400 in the drain.
Anyone planning to buy this Mixergy tanks should think twice before before making that decision. I have learnt my lesson for promoting British made goods.
