    Excellent Value

    Posted by Jeff McDonald on 18th Jul 2021

    Heatso is a first rate vendor. This kit was delivered promptly, and they don't play games with shipping. This heater works great in boats. I prefer diesel for safety reasons. This marine kit is an excellent value. This is the second Espar I've put in a boat. I prefer this style of heater that can be vented out the side and doesn't require a large hole in the roof.
