Cold Concrete Floors in a New Build? We Fixed It in Box Hill

I never thought I'd be the person writing a review about a heating system. But here I am, because when something makes a genuine difference to your daily life, it feels worth sharing. We moved into our new build in Box Hill about six months before we contacted Livella Underfloor Heating, and from the very first cold night we realised the builder's standard heating solution wasn't going to cut it. Searching for proper underfloor heating Sydney options led us straight to Livella, and we haven't looked back since.

Our home is a four-bedroom two-storey house in Box Hill, out in the north-west corridor. It's a lovely area that's grown enormously over the last few years, with new estates all around us. The house was designed with an open plan ground floor, polished concrete in the kitchen and dining areas, and engineered timber in the living spaces. Aesthetically, it's everything we wanted. Thermally, in winter, those floors were punishing.

I want to be clear that the builder didn't do anything wrong. We simply didn't specify heating thoroughly enough at the planning stage, and the ducted reverse cycle system that was included wasn't doing a great job of warming the floor surfaces. The air temperature was fine, but stepping onto polished concrete at 6am was a different matter entirely. We'd started wondering whether we'd made a mistake with the floor choices, which is a horrible feeling in a brand new home.

Understanding the Problem With a New Build

What we didn't fully appreciate before moving in was the thermal mass of polished concrete. It's a fantastic material that holds heat well once it's warm, but it takes a long time to get there. In our house, the ducted system blowing warm air into the room was warming the air but not the slab. The concrete stayed cold until well into the morning, which made the open plan areas uncomfortable during the critical hours when we were getting ready for work and getting the kids off to school.

We started researching hydronic underfloor heating and electric systems separately. The hydronic option was compelling but we'd read that retrofitting pipes into a slab was complex and costly. The electric mat systems seemed more feasible for a partial install, but we weren't sure which areas to prioritise or what product would work best over our polished concrete finish. We needed someone who understood new build heating in Sydney specifically, not just generic advice.

A neighbour who'd used Livella Underfloor Heating in their Rouse Hill home a year earlier put us in touch with them. That referral made all the difference. Within a few days we had a consultation booked and someone on site who actually understood our home.

How Livella Underfloor Heating Assessed Our Situation

What stood out immediately was that Livella Underfloor Heating came in with questions rather than assumptions. They asked about our daily schedule, which rooms we used most in the morning, whether we had kids getting up early, and what our energy usage preferences were. They weren't there to sell us the biggest system; they were there to understand what would actually help.

Livella Underfloor Heating explained that for a polished concrete slab in a new build, electric underfloor heating installed beneath a screed layer or within the slab during construction is ideal, but that a surface-mounted approach using appropriate products was still achievable. They walked us through the practicalities clearly and honestly, including what would and wouldn't be possible without significant disruption to our finished floors.

The solution they proposed was targeted and pragmatic. Rather than a whole-of-home overhaul, they identified the highest-traffic zones: the kitchen, the master ensuite, and the main bathroom. Getting those three areas warm in the morning would transform our experience of the home without requiring us to pull up floors across the entire ground floor. That kind of practical thinking is exactly what you want.

The Installation and the Change It Made

The installation across the three zones was completed over two days. Livella Underfloor Heating managed the process professionally and left the spaces clean and ready to use. Each zone was connected to its own programmable thermostat, which we set to begin warming about an hour before we get up.

The change to our mornings has been remarkable. The kitchen is now one of the warmest spots in the house, which means the whole family gravitates there rather than standing near the ducted vents in the lounge. The ensuites are genuinely luxurious. Getting out of the shower onto a warm floor feels like something from a hotel, and it's made a real difference to how we start the day.

The polished concrete now works with us rather than against us. Once it warms up, it holds that temperature efficiently, which means the system doesn't need to run continuously. Our energy usage has been well within expectations. This is what good underfloor heating Sydney advice looks like: a targeted solution that works with the building rather than fighting it.

What I'd Share With Other New Build Owners

If you've just moved into a new build or you're about to, and underfloor heating wasn't part of the original spec, don't assume it's too late. It's much easier to address early in the home's life than after several years of floor coverings and cabinetry going in. Talk to a specialist like Livella Underfloor Heating before you assume you're stuck.

And if you're still at the planning stage, please have the underfloor heating conversation with your builder and with Livella Underfloor Heating at the same time. Getting it integrated into the slab from the start is the cleanest outcome and gives you the most flexibility. We didn't do that and we still got a good result, but earlier is always better.
