Hot Water Heaters

RCR Energy offers a full range of hot water heating products, from the smaller cost-effective low temperature units to fully condensing heaters - all packaged with exceptionally high quality Weishaupt Burners, which can be offered with integrated VSD & oxygen trim options. 


Our products include:


  • Tomlinson Hot Water Heaters

Traditional low-temperature firetube design, ideally suited to commercial and industrial facilities which require a small, low capital cost heater.


  • Bosch Floor Standing Fully Condensing Hot Water Heaters

The world leader in heating technologies since 1825, Buderus produced the world’s first low-temperature hydronic heating systems. Today, as part of Bosch Thermotechnology, Buderus products are acknowledged as the world standard in high-efficiency, low emissions hydronic heating.  These heaters are quick and easy to install and will outlast and outperform virtually any other commercial hot water heating system.  They are designed for easy access and service.  With appropriate maintenance, Buderus boilers deliver the highest possible efficiencies throughout their operational life.


  • Bosch Cast Iron Sectional Hot Water Heaters

These units offer optimal combustion, low exhaust gas temperatures and high-quality insulation to ensure that these heaters operate at a high level of efficiency, making economical use of resources.
With traditional low-temperature heaters, damage to the surfaces can result from the formation of condensation when the unit is in continuous operation. The Bosch CIS is protected from this by Thermostream technology.  Before the cooler return water comes into contact with the boiler surface, it is mixed with warm feed water and heated. This means that the temperature of the heating surfaces always remains above the dew point and condensation cannot form.


  • Bosch Hot Water Heaters

Larger firetube heaters, high temperature and pressure units up to 19,200kW, manufactured by Bosch in Germany at the former Loos Factory.
