Each bottle contains enough for two
Each bottle contains enough for two full doses to break things down and shift the blockage, followed by two smaller maintenance doses a week apart to keep it clear. A conventional boiler is heat only it doesn’t have to provide hot water on demand but instead heats a water tank the result is that the output from your boiler is much lower it is much closer to the answer to your space heating demand, with a little added on to account for heating the water tank. Leave overnight without turning on taps.
