You've learned to live with a cold house. You don't have to.
Some time in May the socks go on before bed, and by July there's a blanket on the couch that never gets folded away. You heat the room you're in and shut the door on the ones you're not.
A Federation cottage, 1970s double brick or a 1990s project home isn't cold because of its age. It's cold because nobody ever heated it properly – and you can fix that with European radiators, in the house you already own. We size every room, install the radiators ourselves and guarantee the result. No new slab. No demolition.

Hydronic just means warm water moving heat through your home.
Floor heating delivers that heat through the slab. Radiators deliver it through the room: the same quiet, even, fan-free hydronic warmth – from the walls instead of the floor. No blown air, no noise.
Designed right, it runs in the same league as a good reverse-cycle system – without the blown air – and for a fraction of what plug-in electric heaters cost for the same warmth.
For an existing home, radiators aren't the compromise. They're the right tool.
Floor heating
Warm water through pipes in the floor. Superb for a new build – but in a lived-in home it means lifting the floors and laying a new screed (the concrete-like layer the pipes are set in). Worth it in a major renovation, rarely otherwise.
European radiators
Warm water through wall-mounted panels – central heating for every room, from the same hydronic heat source, fitted into the home you already have without ripping anything up.

Radiators can be done wrong too – and then your house just never gets warm.
A box of radiators sized off a rule of thumb holds up fine through May. Then the first real cold snap of July arrives, and the back rooms stop three degrees short of warm and stay there – nothing broken, nothing to point at, just a house that never quite gets there.
Three things cause it:
- panels undersized for the room
- panels in the wrong place
- a heat pump that is wrongly sized or badly sited
Any one of them gives you the system you paid a fortune for: one that never quite heats the house in the depth of winter – or does, but costs far more to run than it should.
The fix is the same as it's always been: the calculation. What does each room actually need, given its glass, its orientation, its insulation? Get that right and radiators are superb. Skip it and you've bought expensive wall ornaments.
Know what every room needs – before anyone sells you a radiator.
Before we quote a single radiator, your Warm Home Plan works out exactly what your home needs – and holds your place in our build queue.

- Room-by-room heat-load assessmentWhat each room needs to actually be warm in the worst of a Perth winter – calculated from its glass, orientation, insulation and ceiling height.
- The right radiators, sized and placedThe correct panel for each room, in the right spot, matched to a heat pump sized and sited to run efficiently.
- Your running-cost number, shownModelled for your home at current rates – shown honestly, never promised, so you know what you're signing up for.
- Your investment range and your slot heldSo you can budget, and your place in the queue is secured while the rest of building life does its thing.
A ballpark, so you can orient yourself: in Western Australia a radiator installation starts at around $3,500 per panel, fully installed on a gas boiler, or around $7,500 per panel, fully installed on a heat pump. These are general figures, not a quote – your real number can land lower or higher depending on your rooms, your layout and the heat source you choose. You'll know the exact price before we start.
Warm every winter, for as long as you own the home – guaranteed on every part we control.
- Warm, and it stays warm. Every room reaches and holds the temperature we designed it for, through Perth's coldest mornings. If it doesn't, we fix it at our cost.
- Warm because the design was right – and if it wasn't, that's on us. If the system underperforms because of our engineering, we correct it at our cost, build consequences included.
- You'll know the running cost before you decide. We model it and show you the number up front, and hold to that model under the conditions we state. We never promise a dollar figure – but we do guarantee the design that keeps it low.
This is a guarantee only the engineer who designed the system can make. No design, no guarantee. Take the plan elsewhere and it doesn't travel – because the guarantee is built on the calculations, and the calculations are ours.
From enquiry to a warm house: the 7 steps.
We manage every step of your radiator retrofit. You don't need to follow the engineering – just know that skipping any step is how a system ends up disappointing.
- We learn about your home and what you want from itThis is not a sales call. We need to understand what you currently have, what is not working, and what comfort you are trying to achieve. Radiators, heat pump hot water, pool – often it is more than one thing. We listen before we say anything.
- We review your home's plans or visit the propertyRoom dimensions, window sizes, orientations, insulation, ceiling heights – we need the actual numbers, not estimates. A room that looks similar to another room can have a completely different heat demand depending on its glazing and which way it faces.
- We calculate the heat load for every roomThis is the step most installers skip. We calculate – not estimate – the watts each room needs to hold its temperature on the coldest Perth night. The calculation drives everything downstream: radiator size, heat pump capacity, pipe sizing. Skip it and you are guessing.
- We select and size each radiator and the heat pumpToo small and the room stays cold unless the water runs hotter, which costs you efficiency. Sized right, each panel delivers its room's watts at a water temperature low enough for the heat pump to stay efficient. The heat pump is sized to the total load of the house – not the other way around.
- We show you the running-cost model before you commitBefore you spend a cent on materials, you see a modelled running-cost number for your home, based on the actual design. This is not a promise – energy prices move and you control how much you heat. But it is an honest, physics-based estimate built from your home's real numbers, not a marketing figure.
- We install everything ourselvesNo subcontracting the parts that matter. We design every millimetre and our team installs it. A radiator installation in an existing home typically takes two to three days. We coordinate the electrical and plumbing connections ourselves.
- We commission, balance and hand over properlyA system that is installed but not commissioned – tested and tuned against its design – is not finished. We balance the flow through every radiator, tune the controls to how your home warms up, and show you how to run it. We check performance during the first heating season. If anything is not as expected, we come back – that is what The Comfort Guarantee means.
"For the first time, we've had a warm house without needing to use heaters in every bedroom or reverse cycle air conditioning – on a cold day it's great to wake up in a warm house."
A heat pump powers the radiators. Your solar can help it along.
A hydronic radiator system needs hot water – typically 45–55°C. A modern air-to-water heat pump provides that at a COP (coefficient of performance) of 3–4, meaning three to four units of heat for every unit of electricity – nearer three at radiator temperatures on a cold morning.
Solar helps most when there is somewhere to store the heat – a buffer tank, a battery, or a solid brick house that holds warmth into the evening. Every unit of midday surplus the heat pump uses is one you don't buy back from the grid at about 33c/kWh. We work out what your roof can actually contribute in July.
We size the heat pump to your home's heat load – not to a rule of thumb – and we integrate it with your solar monitoring so it runs on surplus solar whenever there is some.
Typical COP for a modern air-to-water heat pump in Perth conditions. Actual figures vary by model, outdoor temperature and water temperature. More on the heat pumps page.
The last cold winter can be this one.
Warm every room, and the house stops being something you manage through winter – the heaters come out of the bedrooms, the shut doors open again, and after a while you forget the system is even there.
