Loading…Steel hygiene boiler
A steel hygiene boiler combines heat storage with hygienic domestic hot water preparation through a stainless steel domestic water coil. The tank contains heating water, while domestic water is only heated through the coil during draw-off.
At Hewa, you will find steel hygiene boilers for heat pumps, heating systems, solar thermal systems, wood boilers and pellet boilers. When selecting the right unit, check volume, heat exchangers, domestic water coil, insulation, connections, system temperature, flow rate and hot water capacity.

Selecting a steel hygiene boiler
A steel hygiene boiler is used when heat storage and hygienic domestic hot water preparation need to be combined in one technical storage solution. The tank contains heating water and acts as a heat buffer. Domestic water flows through a stainless steel coil and is only heated during use.
This design is especially useful in installations where larger amounts of heat are available or need to be stored, such as heat pump systems, solar thermal installations, wood boilers, pellet boilers or combined heating systems. The correct choice depends on tank volume, hot water capacity, heat exchangers, system temperature, flow rate, connections and available installation space.
Important when choosing steel hygiene boilers
- Check the steel tank volume and required heat storage capacity
- Check the stainless steel domestic water coil and heat transfer surface
- Match heat exchangers to heat pump, boiler, solar thermal system, wood boiler or pellet boiler
- Check system temperature, flow rate, hot water capacity and heat-up time
- Check connections, sensor positions, insulation and available installation height
- Consider safety components, expansion provision and service space
- Have sizing and connection assessed by a qualified installer
Steel tank with stainless steel domestic water coil
Steel hygiene boilers stand out through the combination of a robust steel storage tank for heating water and a stainless steel domestic water coil for domestic hot water preparation. For installation, protection and maintenance, hygiene boiler accessories are important. Also review the broader category buffer tanks and boilers for additional storage solutions.
When selecting the right unit, system temperature must be reviewed carefully. The lower the supply temperature of the heat source, the more important the heat transfer through the coil and heat exchanger becomes. Always check whether the hygiene boiler matches the heat source capacity, required hot water performance, pipework, control setup and technical documentation.
Frequently asked questions about steel hygiene boilers
What is a steel hygiene boiler?
A steel hygiene boiler is a tank with heating water in which domestic water is heated through a stainless steel coil. The domestic water is only brought up to temperature during draw-off.
What is a steel hygiene boiler used for?
A steel hygiene boiler is used for heat storage and hygienic domestic hot water preparation. The technology is suitable for heat pumps, boilers, solar thermal systems, wood boilers and pellet boilers.
How does it differ from a standard domestic hot water boiler?
In a standard domestic hot water boiler, domestic water is often stored as a supply. In a hygiene boiler, heating water is stored and domestic water flows through a separate stainless steel domestic water coil.
Is a steel hygiene boiler suitable for a heat pump?
Yes, provided the volume, heat exchanger surface, domestic water coil, flow rate and system temperature match the heat pump. With low temperature operation, sufficient heat transfer is especially important.
What should an installer check during installation?
Check connection positions, heat exchangers, domestic water coil, sensor placement, safety components, expansion provision, pipe diameters, insulation, flow rate, service accessibility and technical documentation.
