Blacksmiths sits between the surf and the channel, a beachside suburb of older cottages, holiday houses and newer builds. Lake Macquarie Hot Water connects you with licensed hot water plumbers who service Blacksmiths.
Sand, salt and holiday load
This is an exposed coastal position with the ocean on one side and the lake channel on the other, and the channel is salt water because the entrance at Swansea is permanently open to the sea. Outdoor units here deal with salt-laden air and wind-blown sand, and the result is corroded casings, pitted fittings, seized valves and brackets that let go.
Usage is the second pattern. A lot of the housing here goes from empty through the week to full on a weekend or through a holiday period, which puts a system under sudden load and is often when a fault appears. Older beach stock also means older tanks, which is the standard end-of-life story.
Common hot water calls in Blacksmiths
- Corrosion and sand on exposed outdoor units
- Faults appearing under sudden holiday load
- Older beach stock with tanks past their design life
- Seized or weeping relief valves
- Failed elements and thermostats on ageing systems
Repair, replace or upgrade
A part is a repair and a leaking cylinder is a replacement. If the house is used in bursts, size the system for the full house rather than the average week, which usually points to a larger tank or a continuous flow unit that never runs out. Whatever goes in, mount it out of the salt-bearing wind and off the ground.
What it costs in Blacksmiths
Typical ranges, ex GST: repairs $150 to $600, electric storage from $800 to $2,500 installed, gas and continuous flow $1,200 to $3,500, heat pumps $3,000 to $6,000 before certificates. A coastal-specified install with better fixings costs a little more now and noticeably less over the life of the unit.
Frequently asked questions
Continuous flow or a big tank for a holiday house?
Continuous flow suits a house that goes from empty to full, because there is no stored water to reheat and it does not run out. A large tank is cheaper to buy and fit. Fuel availability decides a lot of it, so check gas availability at your address first.
Does blown sand actually damage a unit?
It does not help. Sand packs into vents, fan housings and coil faces and holds salty moisture against metal. A gentle fresh-water rinse a few times a year and a clear space around the unit are worth the effort here.
How often should a coastal system be serviced?
More often than an inland one. A periodic check that includes the external valves, fixings and, on a heat pump, the coil face picks up corrosion before it becomes a failure on a busy weekend.
