Profile: Weishaupt (U.K.) Ltd. specializes in providing oil, gas & dual fuel burners, heat pumps, and solar systems. We also offer low temperature heating systems and gas fired condensing systems. Our oil & dual fuel burners are suitable for use with fuel oil EL, and low sulphur fuel oil EL to DIN 51603-1. Our brine/water heat pumps convert the solar energy stored in the earth into heat energy. These are available for heating capacities of 5 to 130 kW. Our oil fired condensing boiler, WTC-OW, sets a new benchmark. The modulating pre-mix oil burner doses oil consumption to match the current heat demand, and operates almost silently.
