One of best customer service
I love this heater! At very first I was not entirely sure which heater to get and that is where great folk at Heatso came in help. After a lot of chatting (I was very nit-picking, tbh) they recommended this model and thoroughly explained why. So, I bought it.. Got it super quick! I think it took like 3 to be delivered. Installed it and now I am enjoying amazing comfort this heater provides. Highly recommended! If in any doubt, just ask Heatso folk. They really do care about their customers and helps you through everything.
