Frequently Asked Questions
What’s the best hot water system for a family home?
The ideal system depends on household size, number of bathrooms, and usage patterns. Larger families often benefit from continuous flow or bigger storage tanks, while smaller households may prefer compact electric units or efficient heat pumps.
How do I know when to replace my system?
If your system is over 10 years old, leaking, or no longer providing consistent hot water, it’s usually more cost-effective to replace it. Newer systems are more efficient and often come with better warranties.
Can switching systems save money on energy bills?
Yes, upgrading from an older electric or gas unit to a solar or heat pump system can significantly cut running costs. Even modern continuous flow systems are designed for improved efficiency, reducing long-term expenses.
