About this item
- SHHHH…DOSE YOUR BOILERS with CosWarm CW2 Boiler Silencer. It isn’t very pleasant to be around noisy boilers, but our boiler liquid can effectively solve this problem and restore the heating efficiency of your boilers and radiators.
- GIVE YOUR BOILER SOME TLC: It is crucial that you don’t take a noisy boiler for granted and immediately remedy it with our boiler noise reducer. Our leave-in treatment is a gentle yet highly effective solution that eliminates boiler noise and keeps your boiler bubbling and healthy always.
- SUPER CONCENTRATED & FAST-ACTING FORMULA: Our boiler and central heating system noise silencer can treat up to 18 individual radiators, i.e., a 150-litre system. This ensures that this bottle will go a long way in curing the boilers.
- WIDE COMPATIBILITY: Our boiler noise silencer can be used with most domestic boilers, radiators, pipes and heating systems. It is also compatible to use around metals most commonly found in the heating systems, including aluminium.
- SAFE FOR YOU, THE BOILERS & THE ENVIRONMENT: Our non-toxic and non-acidic radiator silencer is a safer alternative and can be used worry-free around people, the environment and in your heating systems. As this central heating silencer liquid is biodegradable, it won’t harm Mother Nature either.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
