Or try it on the web →This is for plumbers quoting hot water system replacements. It covers like-for-like swaps of gas, electric, or heat pump units. The biggest mistakes plumbers make are under-quoting labour for difficult access and forgetting to price the disposal of the old unit. A good hot water system quote template accounts for the whole job, from draining the old tank to signing off the compliance certificate. Getting these details right at the start protects your margin and prevents arguments with the customer later on. It ensures you get paid for every part of the work.
How to Price a Straight Swap vs. an Upgrade
A straight swap is the easiest. A 250L electric Rheem from Reece costs about $1300. Labour is 2-3 hours at your standard rate, say $120/hr. An upgrade from electric to gas continuous flow is more complex. The unit, like a Rinnai B26, is about $1600. Then you must add labour for running a new gas line, maybe $60 per metre, plus any new pipework. You might also need a sparkie to install a GPO. Using a quoting app like QuoteMate helps you add these separate line items so the customer sees the value and you don't forget the costs.
What Gets Left Off: Access, Disposal and Compliance Costs
The unit's location changes the job completely. A system in a tight roof cavity or on a second-storey wall needs more labour than one in a garage. Add an hour or two for access. Getting rid of the old unit isn't free; most council tips charge $50-$100 for scrap metal disposal, plus your time to get it there. Every new installation requires a tempering valve to comply with AS/NZS 3500.4. This part is about $120 from Tradelink. Finally, include the cost of the compliance certificate required in your state. These small items add up.

Frequently Asked Questions
Yes, it’s mandatory under AS/NZS 3500.4 for all new storage hot water installations to prevent scalding. The valve limits water temperature at the tap to 50°C. Forgetting to quote this $120 part plus labour means you’re either non-compliant or doing the work for free. It’s a required line item.
Charge for your labour plus the tip fee. Labour is usually 30-45 minutes to drain, disconnect, and move the unit. Then add the disposal fee from your local council, which is often between $50 and $100. If it’s a heavy unit in a tricky spot, add extra labour for a two-person lift.
Yes, the initial unit cost is higher. A standard 250L electric unit is about $1300, while a quality heat pump of a similar size from a supplier like Reece can be $3500-$4500.
