I’m really not happy with this company. I went to the post office and shipped the boiler back the next day Dec.13. I came home and sent them a picture of the package with the postage amount and gave them the tracking number. I have not heard anything back from them after 2 weeks, and I haven’t been refunded the return postage yet. I sent an email a little while ago and requested that they send me my new boiler or refund my money. They may make nice products but they have horrible customer customer service. I don’t see myself ever dealing with them again.
