Combined Heating and Power Units
Given a sufficient number of rooms (at least 35 rooms for an older hotel, or 45 rooms for a new-build with modern standards of insulation), the XRGI 15G or 20G combined heat and power units can be an excellent choice.
Owner operators aim to maximise the running hours of CHP in hotels, thereby substituting grid power as much as possible with site-generated electricity. For CHP in hotels, SAV help to ensure this by providing advice on the optimizing of pipe layouts around the CHP unit. SAV have been involved in project discussions of renewables for a number of different hotel chains, thus building up a knowledge of the “house rules” followed by each chain.
HVAC Distribution Manifolds
FloCon modules can help with all commissioning tasks required for FCUs, chilled beams, trench heaters and radiant panels. Up to 7 terminal units can be accommodated by a single module, subject to a limitation of 1.12 l/sec on total flow. SAV offer to plan the module clusters (ie, assigning the terminal units to specific modules) by working off the project layout drawings. Having obtained the corresponding branch pipe lengths, pressure drops can then be calculated and specifications drawn up for the controlling 2-port valves. The result for each cluster is self-balancing, simple to install and effective to commission.
Energy Metering and Management
New build hotels are covered by the requirements of Part L of the Building Regulations. These hold that sub-metering in non-residential new builds should be able to account for 90% of the estimated annual energy consumption for each fuel. The SAV Kamstrup range helps to meet such requirements with energy meters of various sizes and data logging equipment.
DHW & BCW Manifolds
Multiple connections required by on-suite bathrooms are an ideal application for hot and cold water manifolds. Line isolators are integral to the manifold, which is a great space-saving feature. The assembly is bracket-mounted with cold water connection to sinks, bath, shower and toilet, with hot water connection to the first four. Pressure-reducing valves are used on both services, with a pressure gauge on HW service to verify tap supply is kept within limits.
Where underfloor heating is specified, SAV can offer a wide range of UFH manifolds. The version illustrated has its own circulator, and comes with a temperature control mixer assembly just above the pump. Each floor circuit is controlled by a 2-port valve, with local temperature display. Drains and automatic air vents come as standard.
Valves, fittings and flexible piping
FiltraCIM valves, as supplied by SAV, have an integral strainer which is easily removable, needing only the temporary closure of the ball isolator.
We have a range of heating and power systems and solutions, which can be tailored to the requirements of any hotel.
