Electric storage units are the most common hot water system in Budgewoi's affordable fibro
housing stock. Many properties still have original 125–250L units from the 1980s–90s
— now well past their 8–12 year lifespan. Replacement is usually same-day with a
like-for-like unit.

home)
$900–$1,100
2–3 hrs
250L unit (3–4 person

Heat pumps use 60–70% less electricity than standard electric storage systems and suit the
mild Central Coast climate year-round. NSW government rebates under the Energy Savings Scheme
can reduce the upfront cost significantly. The best long-term upgrade for Budgewoi homeowners
with space for an outdoor unit.
Heat pump supply & install (200–300L)
$2,500–$4,000
Half day
NSW rebate (Energy Savings Scheme)
Up to $1,000
Ask your plumber about current rebate eligibility — amounts
change regularly.
Natural gas is not reticulated to most Budgewoi streets — LPG (bottled gas) is the gas
option here. LPG continuous flow systems provide unlimited hot water on demand and are popular
in compact fibro homes with limited outdoor space for a heat pump. ELGAS delivers 45kg bottles
or bulk LPG to the area.
LPG continuous flow (supply & install)
$1,200–$2,000
Half day
Gas compliance certificate
Included
All LPG hot water installs require a licensed gas fitter and a
Certificate of Compliance lodged with Fair Trading NSW within 5 days.
Budgewoi's position on the Central Coast gives good solar access, especially for north-facing
rooftops. Solar hot water systems can reduce water heating costs by up to 80%. They pair well
with homes that already have or plan solar PV panels.
Solar hot water (supply &
install, incl. booster)
$3,000–$6,000

Annual saving (vs electric storage)
