Frequently Asked Questions
Everything you need to know about AIZO Quality Heating solutions and services.
How do I know which heater size is right for my room?
Selecting the right heater depends on the square footage of your space and the insulation quality. Generally, we recommend 10 watts of heating power for every square foot. You can use our online sizing calculator or contact our support team for a personalized recommendation.
What is the standard shipping timeframe for heating units?
Most orders are processed within 1-2 business days. Due to the size and weight of premium heating units, standard ground shipping typically takes 5-7 business days. Expedited shipping options are available at checkout for smaller components.
Do AIZO products come with a manufacturer warranty?
Yes, all AIZO Quality Heating products are backed by a comprehensive 2-year limited warranty covering manufacturing defects. Certain premium models may qualify for an extended 5-year warranty upon product registration.
What is your return policy for installed units?
We offer a 30-day return policy for items in their original packaging. Please note that once a unit has been professionally installed, it is no longer eligible for a standard return unless a manufacturing defect is confirmed by our technical team.
Are your heating systems energy efficient?
Absolutely. We specialize in high-efficiency technology, including programmable thermostats and eco-mode settings designed to reduce energy consumption by up to 30% compared to traditional heaters.
Which payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express), PayPal, and Apple Pay. For larger home renovation projects, we also offer flexible financing options through Klarna and Affirm.
