WarmZilla FAQs

What payment methods do WarmZilla accept?

WarmZilla accepts all major Debit/Credit Cards.

How much does a new boiler cost?

The price of a replacement boiler really depends on the size of your property and how much hot water is required from your new boiler to efficiently service your home.

Are your engineers fully qualified?

Yes, all of their engineers, or ‘WarmInstallers’ as they are called are all gas-safe registered as a minimum requirement.

What can I expect on installation day?

The WarmZilla engineer will arrive with your boiler and all the necessary parts. They usually arrive between 8-11 am but they will call to let you know when they will arrive.

What type of boiler do I have?

If you do not have a hot water cylinder and tanks in your attic then it is likely you have a combi boiler. If you do have a hot water cylinder and tanks in the attic, then it is likely you have a standard or back boiler unit. If you just have a hot water cylinder and no tanks in the attic it is likely you have a system boiler.
