Good product, solidly made Very fast delivery, solidly processed product. The installation in a Bayliner 2655 was done in 30 minutes after removing the original boiler. All parts could be reused. In addition, I only needed Teflon sealing tape. The heating time is acceptable, around 30 minutes for 50C.

As a replacement for Truma Therme Although I have installed the boiler in the caravan, contrary to the operating instructions, I am very satisfied so far. Heats up the 20 liters of water relatively quickly.

Good product, but add a mixing valve Works great out of the box, but I recommend adding a mixing valve. The engine coolant will bring the temps to almost boiling, you risk getting burned or damaging the hoses going to the faucets if that super hot water is not mixed with cold when exiting the boiler. Using the electric heating element takes about an hour to heat up the water in the 30l version .
