Are you considering replacing your current hot water system, or does a cold shower surprise you every morning? A sanitary heat pump is one of the most efficient, quiet, and environmentally friendly solutions for heating domestic hot water.
A sanitary heat pump is a device that uses heat from the air – from inside the building, the surroundings, or waste heat – to produce hot water. It is one of the most efficient methods for heating domestic water, consuming over four times less electricity than conventional electric heaters.
Do you have a pellet, wood, or oil boiler that you have to run even in July just to heat water for showering? That means high costs, unnecessary work, and wasted time. A sanitary heat pump operates quietly, efficiently, and fully independently – without burning fuel and without energy loss. It can even cool spaces like a pantry or cellar.
Especially in larger households or premises where water is used for services (hair salons, beauty studios, apartments), a shortage of hot water can occur. This is a clear sign that your system can no longer meet your needs.
Sanitary heat pumps, with their large storage tanks and high efficiency, provide sufficient hot water even with higher consumption.
A sanitary heat pump with around 300 litres capacity is suitable for:
For a typical 4-person household using around 200 litres of hot water daily, switching from a conventional electric boiler to a sanitary heat pump can reduce energy consumption for hot water production by up to 75%. This not only means significantly lower energy bills, depending on local electricity prices, but also offers quieter, automatic operation, greater control, and the added benefit of cooling spaces like a cellar if desired.
Older electric boilers – often over 10 years old – are among the biggest electricity consumers in a household. They also lack modern safety features, smart controls, schedules, or remote control. This means they heat water unnecessarily and don’t consider electricity pricing.
Over time, limescale builds up on the heating element, especially in areas with harder water, reducing heat transfer efficiency and potentially increasing electricity use by 30%. There’s also a hygiene risk, like Legionella development in poorly maintained or underheated water.
A sanitary heat pump solves these issues with Legionella protection, safety valves, and automatic or remote control via app. The condenser doesn’t directly contact the water, so there’s less limescale. You can also set the water temperature below 55°C – the critical point where limescale forms more rapidly. It offers safety, hygiene, convenience, scheduling, and consumption monitoring.
Most older hot water systems don’t offer remote control, schedules, or adaptation to actual needs. This could mean cold showers if you forget to turn the heater on or unnecessary heating, raising costs. You also can’t start heating before returning from holiday.
A sanitary heat pump allows:
Do you wait minutes in the morning for hot water? This problem is common with electric boilers or systems without circulation pumps, where the heater is far from the bathroom or kitchen. This can waste thousands of litres of clean drinking water a year, along with time, energy, and money.
The KRONOTERM sanitary heat pump solves this with:
Old systems heat water regardless of time, tariff, or grid load – often when electricity is priciest and the grid is most stressed, raising network fees and your bill.
Sanitary heat pumps allow:
Heating hot water with conventional electric heaters or fossil fuels means high energy use and CO₂ emissions. Sanitary heat pumps consume 75% less electricity, using renewable heat from the air.
A 4-person household can save over 1,100 kg CO₂ a year – like avoiding 9,500 km of car travel. Powered by solar panels, water heating is virtually carbon-free.
Replacing your boiler with a heat pump is one of the simplest steps you can take to reduce your home’s carbon footprint – without sacrificing comfort. Contact us and we will help you find the best solution for your home.
It uses over 4 times less electricity than a conventional boiler – about 1,050 kWh/year for a 4-person family versus over 4,200 kWh.
Yes. KRONOTERM sanitary heat pumps offer app control, scheduling, consumption monitoring, and pre-heating before you get home.
Sanitary heat pumps allow timed heating and hot water circulation – so water is ready when you need it. Cold showers usually result from manual operation or poor scheduling.
If your boiler is over 10 years old, has limescale buildup, doesn’t provide enough hot water, lacks smart controls, or costs are high – it’s time for a change. A sanitary heat pump offers a modern, safe, and economical solution. Contact us – we’ll help you find the best option for your home.
