Our Hot Water Services
Repair or replace. Gas, electric, solar or heat pump, there's no hot water system we can't sort. Fully equipped vans, same-day across Sydney.
Lost Hot Water? Here's Why You Shouldn't Wait
Most hot water failures come down to one of these. The longer you leave it, the colder the showers get, and the more it can cost.
Faulty Element
Pilot Light Out
Thermostat Failure
Tank End-of-Life
Burst Tank
Cold showers are the least of it
A stagnant, cold tank can breed legionella, tenants start ringing, and a small fault left too long becomes a flooded laundry. That's why Mr Flow runs 24/7, so you're back to hot water fast.
How It Works
No waiting around. No vague ETAs. Three steps and you're back to hot showers.

What Sydney Says About Mr Flow
"Woke up to a freezing morning and no hot water, old tank had finally carked it. Harry's crew had a new system installed the same day, and I got the cashback too. Couldn't fault them."
"Pilot light kept dropping out on my gas system. They had it fixed in 20 minutes for under a hundred bucks, honest blokes who didn't try to flog me a whole new unit. Highly recommend."
"Manage a rental and my tenant had no hot water. Rang Mr Flow and they replaced the system the same day, handled everything directly with the tenant. Made my job so easy, my go-to now."
