Commercial boilers offer three temperature circuits
Vokera’s Condexa Pro range of wall-hung condensing boilers have three circuits for domestic hot water, high-temperature heating and low-temperature heating such as underfloor. There are three models providing outputs from 50 to 400 kW. They can be supplied with master and slave boards for multiple operation. The Condexa Pro features a modular system and pre-mixed air-blown burner with one or more heating elements in series. There is a stainless-steel condensing heat exchanger on the exhaust side and a copper-alloy exchanger on the water side. Flue runs can be up to 30 m.
