Treat your central heating system to the Trident T400 Central Heating Sludge Remover. This 500ml concentrate solution can restore circulation and even heat distribution to systems up to 100L. Its non-acidic treatment makes it ideal for older heating systems.
It quickly and effectively removes stubborn magnetite sludge and eliminates cold spots in radiators, therefore restoring circulation to radiators and pipework.
Restore your central heating to optimal performance with the Trident T400.
T400 can prepare older systems for the installation of new components and is suitable for use in all types of indirect heating systems, including aluminium.
How to use
Open systems should be closed via F&E cistern (adequate draining from low point is
recommended to ensure that all the T400 enters the circulating part of the system). Sealed systems: T400 should be injected into the filling loop or other access point. If the system is empty, pour T400 into any convenient point prior to filling.
Cleansing
Circulate T400, with all the valves open, for a minimum of 2 hours after central heating
has maintained working temperature but can be left in for up to four weeks.
Dosing Rate
T400 should be dosed at 0.5% of system volume – i.e. 500ml of T400 per 100 litres of
the system’s water. Generally, one bottle contains enough for an average central heating system.
For larger systems use an extra bottle of T400 - over-dosing will not cause any detrimental effects to the system.
Please note: where a thermal storage appliance is fitted, allowance must be made for the increased volume of primary water. The concentration may be checked with a conductivity meter.
Important Notes
T400 must not be left in the system. Do not add to primatic system.

Watts & BTUs (British Thermal Units) Explained
What is a Watt?
Watts are our main unit of energy/power in the UK, commonly associated with lightbulbs and Home Energy performance certificates (EPCs).
What is a BTU?
BTUs are the unit of measurement used to portray a radiators heat output and a rooms heating requirement. 1 Watt is equal to 3.41 BTUs.
Why are they important?
We buy radiators to heat our homes, right? So, we need a way of knowing if a radiator is powerful enough to heat the room that we are shopping for - Watts and BTUs provide us with a value that makes its easier to compare radiators and ultimately choose the right one for our heating requirement.
Need help figuring out how much heat your room needs?
Our fast and easy-to-use BTU calculator can help you:
- Work out a heating requirement value (in BTUs & Watts) for your room
- Show you in-stock radiator recommendations that can fulfil this heat requirement
Delta (Δ) Ratings Explained
What is a Delta (Δ) Rating?
When discussing heat outputs, the Delta rating is the difference between the temperature of the water inside the heating system and the desired temperature of the room.
What does the value represent?
In simple terms, this value is about heat loss. Heating a room only works, if the radiator output exceeds the heat loss of the room.
We use this calculation to make it easy to choose a radiator that will have a heat output that exceeds the heat loss of the room when connected to your heating system type.
If you don't know the room heat loss, you can use our calculator to find out.
What Delta Rating should I use?
- Δ50 = Gas or oil boiler with a flow temperature of around 75°C and a return temperature of around 65°C.
- Δ30 = Low temperature systems e.g heat pumps.
