Rated 5 out of 5 by from Worth the extra cost Within 1 hour all the radiators were hot top to bottom. Due to time constraints I had to leave in the system for 22 hours but sensed I could have drained it within a couple of hours. Wont ever go for cheaper options again.

I'm looking to flush out the heater core in my car. I plan to pump this product, undiluted, around the heater core for several hours to try and break down some of the corrosion. Would it be suitable for this application?

Limescale removal?

Will this also act as a boiler descaler? So no need to additionally dose with X200 descaler?

Answer: 
Hi there, the prime function of Sentinel X800 is to clean corrosion debris from a dirty central heating system and not to specifically descale a boiler. It will have some effect but if the problem is boiler noise then Sentinel X200 is the best product to prevent boiler noise.
Kind regards

Answer: 
Hi there, a 1 litre bottle of Sentinel X800 Jetflo is sufficient to clean a typical system of approximately 8 to 10 radiator panels. For larger systems 2 litres of product should be used. Where systems are badly fouled, a higher concentration is recommended, i.e. 2 litres of Sentinel X800 Jetflo in a typical system, though the product will not clear a completely blocked pipe.
Kind regards
