Floor-standing boilers have design features aimed at the replacement market
Designed to fit into the space occupied by one of the most popular traditional boilers so as to reduce installation costs — Broag-Remeha’s Gas 110 boiler range.
To reduce the cost of replacing existing boiler plant with a fuel-efficient condensing model Broag-Remeha has introduced the Gas 110 Eco floor-standing boiler which has been specially developed to fit into the same floor area as one of the most popular traditional boiler designs of equal output. One of the major savings is avoiding much of the cost of modifying pipework and associated fittings. These boilers also pass through a standard doorway. Their footprint is 600 x 663 mm, the difference in output being due to height. The range of features of these boilers also makes them ideal for new-build. Combustion efficiency is up to 110%, with SBEM seasonal efficiencies of up to 97.6%. NOx emissions are also very low, at 32 mg/kWh for the smaller boiler and 35 mg/kWh for the larger one. Output is precisely matched to heating demand to achieve energy savings of up to 30% compared with conventional technology. Because of the energy-saving potential of these boilers, national sales manager Mark Northcott argues that they can be more effective than renewable energy — with the financial equation making it possible to install condensing boilers on several sites for every one that uses renewable technology. In addition, the Gas 110 Eco is included in the Climate Care carbon-offset scheme offered by Broag-Remeha to its customers to help them promote a near-neutral carbon balance. The two boilers in the range have outputs of 65 kW, modulating down to 13.3 kW, and 114 kW, modulating down to 18.4 kW. For larger outputs, up to six boilers can be linked together using Broag-Remeha’s ‘Smart Connection Technology’ pipework kits. Boilers can be installed in line or back to back. Features include a variable-speed fan for combustion air, downward-firing pre-mix burner and one-piece cast-aluminium heat exchanger. They can be fuelled by natural gas or LPG. There is a wide range of flue options — from room-sealed concentric (horizontal and vertical) to twin-pipe CLV systems through to common header arrangements and including flue-dilution options. Controls and control options offer sequence control, weather compensation, HWS priority and BMS interface. Intelligent boiler control reacts to negative influences on the system to maintain boiler output for as long as possible and reduce lock-outs.
