I began looking for parts on your website and the initial google search took me to a bosh water heater. I was a little unsure about that particular part and so I wrote to your "ask a professional" section. He replied to me within about 24 hours. The part that Google directed me to was not correct and the technition from your website helped me find the right part very quickly. Shipping was extrememly quick and the price couldn't be beaten anywhere on-line. The heat pump was a little time consuming to change for a novice, but I got through it. I also saved several hundred dollars over what I was quoted by a repairman (and had a lot of fun doing it).
