Common questions

Questions about hot water boilers

Pressurised or atmospheric hot water boiler — which one?
Pressurised boilers (WNS, LDR, DZL) work at 0.7 MPa and above and suit closed heating networks and higher supply temperatures. Atmospheric boilers (CWNS, CLHS, CLDR, CWDR) run without pressure in the boiler body, for heating and washing water.
Which fuel should I choose for a hot water boiler?
Gas or oil (WNS, CWNS, CLHS) where the fuel is available, electric (LDR, CLDR, CWDR) for no combustion on site, and DZL for biomass or coal where solid fuel is the cheapest.
What do you need for a quotation?
Output, working pressure, fuel, power supply (for electric units), the application and the destination country.
