1.negative pressure, 2.Multi-purpose, 3.High efficiency, 4.Integrated design,convenient for installation, 5.Low operating cost - details see: https://www.machineto.com/vacuum-hot-water-boiler-10212039

Features:

1.Long-life design

Heating medium is purified & deoxy water which is sealed in vacuum chamber of the boiler,with no need for feedwater, no crrosion,no scale,no efficiency attenuation.low operating cost,the boiler working life as high as 20 years.

2.Multi-purpose

With different heat exchanger, the boiler can be used for indoor heating(air-con,radiator)and bath water. user can set multiple circulations for heating, bathroom,sauna,swimming pool or thermostatic breeding.

3.Integrated design

Boiler & heat exchanger integrated design save on space and easy for installation, the boiler can be placed in basement, first floor or the roof of buildings without complicated approval formalities,low installation cost.

4.Numerical control system

Adopt numerical control system including Automatic Mode,Manual Mode, Timing Mode, Error Recording function,password protection function,etc. User can easy handle the boiler via a LCD touch screen.
