Machine A Laver Hotfill __top__ May 2026

Imagine you have a modern condensing boiler (gas or heat pump), solar thermal panels on your roof, or a well-insulated hot water tank. Heating water centrally is often much cheaper per kWh than using electricity at peak rates. In many European homes, gas is a third the price of electricity. If your washing machine pulls hot water directly from the tank, it’s not using its 2kW heating element at all.

So next time you hear “hotfill washing machine,” don’t think of a clunky 1980s relic. Think of it as the appliance that remembers we used to heat water once and use it well — and now, with the right tech, we can do that again, cleaner and cheaper than ever. 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. Imagine you have a modern condensing boiler (gas

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. If your washing machine pulls hot water directly

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.
