Fitted my first Alpha E-Tec 28 yesterday with a standard 5 year warranty, I have to say the installation was extremely easy, the price and warranty for the E-Tec I was pleasantly surprised especially with it’s major components inside such as a Honeywell GV and PCB, a Grundfos block, a stainless steel heat exchanger and a great feature of a combined PRV and condense. I will certainly be fitting more of these in 2019. It’s also nice to have a rep in my area that genuinely cares for the product and is interested in my business needs, nice to meet you Steve.
