thermoreg. pump units
IVAR.TERMOVAR thermal regulation units with circulation pump and non-return valve prevent low-temperature corrosion and tar build-up in solid fuel boilers. The DN 25 version is designed for boilers up to 35 kW, DN 32 up to 65 kW, and the replaceable insert sets the temperature at 55, 61, 72 or 80 °C; 1" and 5/4" pump groups complete the range.

Frequently Asked Questions
- What is a thermoregulating pump unit used for? It protects a solid fuel boiler against low-temperature corrosion by letting return water into the boiler only once it reaches the set minimum temperature, while also containing a pump for heating water circulation and an integrated check valve.
- What does the temperature stated for individual variants mean? It is the temperature at which the unit's thermostatic element opens and starts mixing return water into the boiler circuit – it is selected according to the recommendation of the manufacturer of the specific solid fuel boiler.
