Customer Reviews

★★★★★ 5/5

I can trust my PHP heater to work in our RV even on the coldest nights. I'm glad I chose PHP and always make sure to recommend them to everybody at the camp ground!

I needed support for my boat heater just before a big fishing trip and DKSI was able to get me a new part within a couple of days. That's way better than when I was ordering from Europe and the parts took weeks to arrive.

Northern Alberta gets ridiculously cold, and even in a sealed cab that winter air is biting so parking heaters are critical up here. This time, I gave a PHP heater a shot and it was just as good as the Webasto I used to run - but half the price! Highly recommended.
