Right here for home builders

Hot water sorted. Every project, every time.

Envirosun works with residential builders across Australia to deliver reliable hot water supply, 7-star compliance, and competitive project pricing — backed by a local team who picks up the phone.

Why choose Envirosun?

Most hot water brands are focused on consumers and adapted for builders as an afterthought. Envirosun is different. We’ve designed our supply model, pricing structure, and support system around the way volume builders actually work — with forward ordering, consistent product specs across all stages, and a team that understands what a delayed delivery costs a project.

Which is not to say your customer – the homebuyer – isn’t also best served by having Envirosun hot water. Our systems are up to 30% better value than comparable products, backed by a best industry-best 10-year warranty — stronger selling points for you and more peace of mind for your homebuyers.

We’re Australian-owned, locally operated, and stocked in every capital city. Whether you need hot water sorted across 10 lots or 100, we have the supply, service and advice to back it up.

"Envirosun's always been our go-to. Parts arrive fast, the tech support line actually picks up, and my customers haven't had a hot water call-back in three years. That's what keeps me recommending them."

The most cost-effective way to hit 7-stars.

Under the National Construction Code (NCC), new residential builds must meet 7-star energy efficiency requirements. A solar hot water system is one of the cheapest and most reliable ways to get there — and Envirosun systems are fully compliant and certified.

We carry the documentation builders need to satisfy assessors and certifiers without the back-and-forth. Check out our superior STC incentives on our product pages and the buttons below to download our Compliance Certificates and check our energy ratings.
