The Hills is the part of Sydney where the full range of hot water options is genuinely open. Large blocks, room beside the house, and space for airflow mean heat pumps and solar are practical here in a way they are not in a terrace or a unit — so the conversation is about what to install rather than what will fit.

Heat pumps need clearance and airflow, and solar needs roof area and a tank position. Hills blocks generally have both, which puts options on the table that inner-suburb homes do not have.

Bigger households run out of hot water faster. Sizing matters more here, and the unit that suited the previous owners may not suit you.

In a large home the distance from the unit to the far bathroom means a wait for hot water and heat lost along the way. Placement and insulation are worth getting right.

Common Questions

On a Hills block with space and airflow, often yes — running costs are substantially lower than electric storage. They do make noise, so placement relative to bedrooms and neighbours matters.

It depends on household size and peak demand rather than house size. We will size it on how many people shower in the morning, not on square metres.

Had trouble with our hot water system for weeks and was unable to figure out the issue. Matt and Anthony came out the same day I enquired and the issue was resolved within an hour. Couldn’t recommend enough!

I would highly recommend Anthony and Matthew from Mr Clog plumbing. They were easy and trustworthy to deal with and fixed my leaking hot water system in no time.
