Can I have solar hot water without the tank on my roof?

Residential house with solar panels on the roof after being installed by Solahart.

A Solar hot water system is a smart way to reduce the energy used to heat your household water. It stores energy from the sun for later use like a home battery, but in the form of hot water, helping you minimise your reliance on the grid.

Solar hot water is more affordable than a home battery and considering that water heating makes up about a quarter of an Australian household’s energy use on average¹, going solar is a great decision.. .

Our most popular system is a roof-mounted solar water heater.. However, we often get asked whether you can still have the benefits of solar without the tank on your roof. You definitely can, and in this article, we will explore three great alternative options.

Types of renewable hot water systems without the tank on the roof
1. Split system water heater

In a split system, the storage tank is discreetly placed at ground level and connected to the slim solar collectors installed on the roof. This is a good option if you’d like solar but prefer not to have the tank on the roof.

Why choose a split system?

Flexibility of tank installation locations, including inside your home if feasible
Perfect if you have limited roof space or shading issues
Less visible from street level

Why choose Solahart PowerStore?

3. Heat pump water heater

If solar is not for you, it doesn’t mean you can’t enjoy the benefits of renewable energy. Rather than using the sun’s energy, a heat pump, installed at ground level, draws energy from the surrounding air to heat your water.

Why choose a heat pump?

Requires no roof space – can be installed in the same location as your previous storage water heater
