I almost got robbed $1000 to fix my Eco-King boiler. Good thing I Googled their website and phoned them. Luckily support technician is available 24/7 (James Montina) he guided me to change my own boiler mother board and it's so easy. Also another technician helped me calibrate my boiler (Chad). Now everything is working good. I have hot water and heating . Thank you so much for your above and beyond service eco king technician.
