Frequently Asked Questions!

Have a particular problem or question. You may find the answer here.

What evidence do manufacturers require for a warranty claim?

Manufacturers require the benchmark logbook to be fully completed. They also look for proof of ongoing water treatment and annual servicing. Continuous testing provides the digital paper trail needed to prove the system has been maintained to their standards.

How does the Home Heating Test Kit protect my warranty during a professional clean?

The ability to re-test turns the the aHome Heating Test Kit into a 'Certificate of Completion.' If Test ONE fails, and the job has been done correctly, Test TWO should pass. If not, the contractor must re-do the work. It holds trades accountable and ensures the water meets warranty standards.

Will dirty system water void my new boiler warranty?

Yes. Every major boiler manufacturer specifies that the system must be thoroughly cleaned and treated before installation. If a part fails and the manufacturer finds thick sludge or poor water quality, your warranty claim will be rejected immediately.

Will adding my own chemicals affect the warranty?

Using unapproved or incorrect chemicals can cause internal damage. It is vital to use an approved inhibitor that acts as a true System Guard. Unregulated DIY mixtures or the incorrect application of a Reagent 1: Corrosion Catalyst can accelerate degradation and void your cover.

Do I need to flush my radiators if I only replace the boiler?

Absolutely. Connecting a pristine, high-efficiency boiler to old radiators filled with magnetite and rust will instantly contaminate the new unit. The entire circuit must be flushed to protect the new heat exchanger and validate the warranty.
