Machine — A Laver Hotfill

That’s where the hotfill machine becomes a quiet hero. Some dishwasher and washing machine models (e.g., from Miele, AEG, or even specialized brands like Hotfill) offer a hotfill option. A few, like the V-ZUG Adora line, are designed to take pre-heated water up to 60°C. When you select a 60°C cotton cycle, the machine simply opens the hot valve, adds a little cold to temper it if needed, and gets to work. The heating element might never turn on. Tests by the UK’s Energy Saving Trust found that using hotfill from an efficient gas boiler or heat pump could cut a washing machine’s energy use by 40–70% for hot cycles (40°C and above). For a household that washes sheets and towels at high temps, that’s not trivial.

Here’s an interesting, slightly quirky piece on the machine à laver hotfill — a concept that sounds obsolete but is quietly making a comeback in the age of energy efficiency and smart home tech. At first glance, asking for a machine à laver hotfill feels like requesting a VHS rewinder or a fax machine. For decades, modern washing machines have been strictly coldfill — plumbed only into the cold water pipe, relying on an internal heating element to raise the water temperature. Hotfill machines, which connect to your home’s hot water tank or boiler, seemed to vanish from showrooms in the 1990s. machine a laver hotfill

And if you’re renovating your laundry room? Maybe run that hot pipe after all. Your future self, washing sheets on a sunny winter afternoon, will thank you. That’s where the hotfill machine becomes a quiet hero

Even on a 30°C eco cycle, a clever hotfill machine could draw cold water if the incoming hot is too warm. But if your solar thermal panels have been baking all afternoon, that 30°C comes free from the sun. Hotfill only works if your hot water is delivered quickly and at a usable temperature. If your boiler is across the house, the first litres of water will be cold as the pipe purges. You’d waste water and energy waiting for heat to arrive. That’s why hotfill machines are most popular in countries like Germany and Switzerland, where homes often have recirculating hot water loops or compact combi-boilers near the utility room.
