Having recently gone to all the extent to seal up all the drafts in the house we started to suffer with condensation on the windows. Got sick of going around in the mornings with the old Karcher so started to do a bit of research and came across the DRIMASTER ECO with HEAT. With all the positive reviews we bit the bullet and placed our order. 2 days later it arrived and I set about installing it. I found this easy to install with limited DIY skills and easily paired the system with the separate remote switch. The following morning VOILA, no more condensation problems. Not ran it with the heat as yet as wanting to keep the running costs as low as possible but I have no hesitation in recommending this unit. The whole process with i-sells from order to delivery was 1st Class.
