I love your product but I should of ordered the larger heater instead of the small one. I placed it in the engine compartment of my Cigarette boat with twin engines. Once the weather was lower than 32 deg it had a hard time keeping up. It's a small compartment about 6ft X 8ft X4ft with a hatch cover along with 3 top covers and vents are 99% covered. It was 25 deg outside and heater got to 31.6. Thank God i had wifi thermometers in there so i know the temps 24/7. Or i would possibly be buying new blocks. I then had to put an additional heater inside which is now at 56 deg. I may use it next year for the basement of my motorhome but then I don't think it will be powerful enough. I do plan on purchasing a much bigger model for next winter.
Ps, I don't think the website accurately describes the performance of the heater.
