Weishaupt gas-fired condensing boilers use almost all of the energy stored in the fuel, converting it efficiently into heat. A condensing boiler uses the energy which in older heating systems is lost to atmosphere with the flue gases. In so doing, nett efficiency is increased to around 110 % compared to less than 100 % for low-temperature systems.

How to choose this product

gas-boiler

A gas boiler uses natural gas, propane (LPG) or butane to fire a hot-water heating system. Some also provide hot tap water.

Standard boilers heat water to 90° C, while low-temperature models heat to only 40° C. Commercial installations feature high-temperature boilers for steam heating. Condensing boilers are very efficient, offering energy savings to 30%. They use condensed steam recovered from flue gases to heat the cold water on the return side of the system.

Choice will depend on boiler capacity and installation configuration (wall, floor, built-in). City gas is the preferred fuel option, offering ease of installation, low cost and efficacy. Propane (LPG) requires tank storage and is more expensive. Low-temperature and condensing models are more economical and environmentally friendly.

- Energy savings
- Easy maintenance

- Uses non-renewable energy
- Produces CO2 emissions
