This 5kW heater is a well-made product, and worked first time, and has been working well since I started using it. I use it to heat a timber cabin 4m x 3m and it is more than capable of heating that room to a comfortable temperature pretty quickly. It might be slightly overpowered for this small space, maybe the 3kW version would have been a better fit. If this product had a true thermostatic control then the extra power would not be a problem. It's a little noisy, not too bad, fine for working alongside it with the exhaust piped externally. Again if it had thermostatic control it would be more convenient as it would only burn as needed.
The wires, pipes, and hoses are of good quality. I did add a cigarette lighter plug to make it easier to connect to a battery box. Remote control works ok but not really that useful since the heater is likely to be in the same room and accessible anyway. The remote only works over short distances so I don't think it would work if the heater was the other side of a partition/wall.
