Ferny Hills sits on the slopes between Arana Hills and the bushland to the west, built out through the 1970s and 80s with brick and timber homes, generous blocks and reserve frontage on a lot of streets. Moreton Bay Hot Water is a free referral service connecting you with QBCC-licensed hot water plumbers who cover Ferny Hills.
Shaded blocks, older systems
The tree cover that makes Ferny Hills pleasant also rules out solar on a lot of roofs. Any installer worth dealing with will do a shading check before quoting solar hot water, and on a shaded block will steer you to a heat pump instead, which draws heat from the air rather than from sunlight.
The systems themselves are mostly electric storage, and mostly a second or third generation. Storage tanks last 8 to 12 years, and the compliance plate on the cylinder is the only reliable record of when yours went in.
Blocks here are generous enough that placing a heat pump is rarely a problem. It needs airflow and a position where the compressor hum does not sit under a bedroom window, yours or the neighbour's, and on these blocks that is usually easy to arrange.
Costs, from swap to upgrade
A like-for-like electric storage swap runs from around $800 to $2,500 installed. Gas storage and continuous flow sit around $1,200 to $3,500 installed where gas is connected, and availability varies street by street. Repairs on younger systems run roughly $150 to $600 depending on the part.
Heat pumps run around $3,000 to $6,000 installed before incentives, with federal Small-scale Technology Certificates reducing the net installed price on eligible models. These are guide figures and the plumber's quote is the price that counts.
Frequently asked questions
Does bushland frontage affect the install?
Mostly in terms of where the unit sits and how much leaf litter gathers around it. A heat pump needs its airflow kept clear, which is worth knowing on a bush block.
Will a heat pump cope in winter here?
Yes. Winters are mild and most units carry a backup element for the coldest mornings. Efficiency dips slightly, and running costs stay well below a standard electric tank.
Can solar and a heat pump be compared properly?
Yes, and they should be. Ask for both quoted as net installed prices for your actual roof and household, rather than comparing brochure figures.
