We purchased a Premier Heat electric Flow Boiler radiator version in 2016 for our holiday home in Scotland. It broke down in March 2017, after 8 months. I spoke to their technical department and was able to have a NEW replacement PCB under warranty.
However, it broke down again while we were out of the country...on our arrival in Scotland in April, we found the house freezing with no heating.
Apparently the boiler we purchased is only under warranty for 2 years!!!! Reading details on their site it mentions that all parts have a warranty of 2 years. Apparently they lied. New parts actually are only guaranteed for the length of the warranty on the appliance. Our new part broke down after less than a year but by the time we realized it was a week or so over the 2 years from when we purchased the appliance, but only a year since the part was replaced with a new one.
I have managed to get a replacement as a " good will " gesture but am disgusted that they are allowed to get away with this.
I got in touch with Consumer advice and they agreed that the boiler was "not fit for purpose " but that I should go to the trader where we bought the appliance from. I didn't want to do this as I feel it isn't his fault but a manufacturing fault with the company .
DO NOT EVER BUY ANYTHING FROM HEATRAE SADIA unless you only want a boiler to last for two years....maybe. The cost of continual breakdowns will far outweigh the purchase of a new heating system. We are getting another form of heating put in to protect our house during the Scottish winters.
It's a disgrace that they can get away with selling rubbish. Surely everyone would expect a heating system to last more than 2 years?
