Leading Northwest contractors, Winrow Building Services, has recently completed an installation of a new high-performance system for heating and hot water production at a 100-plus bedroom Birmingham City Centre hotel.
The hotel is part of one of the biggest hotel chains in the world and the system has been augmented with SPF calculations and complete system integration for maximum operational efficiencies.
The new system consists of 2 x 27kW R290 heat pumps optimised with a bespoke 800 L prefeed vessel and 2 x 500L electric cylinders with 48kW of immersions. The new system replaces an old electric cylinder system of a 1500L storage and 36kW of immersions.
Sited in the heart of England, this Birmingham hotel is ideally located to explore the attractions of the city and the West Midlands. The bespoke Rinnai R290 system upgrade ensures reliable hot water delivery across the hotel’s 111 bedrooms, restaurant and bar area, along with its five conference rooms that can support up to 200 guests.
“This project was all about delivering energy efficiency and long-term reliability,” says Ben Winrow, Project Manager at Winrow Building Services.
“The Rinnai system was straightforward to install, and the bespoke design made integration seamless. The client now benefits from lower running costs, reduced carbon footprint, and a future-proofed system.”
Winrow Building Ltd is a family-owned and run business of over 30 years’ experience in designing, supplying and installing heating and hot water systems and solutions.
Adds Dave Winrow “Our goal with each and every job is to offer the utmost value to clients by prioritising energy and environmental savings without compromising efficiency and performance. Rinnai support us in achieving this with full system integration, SPF calculations and expert support”
Rinnai has R290 heat pumps as part of its array of an extensive list of decarbonising appliances. R290 is a LOW scoring GWP (Global Warming Potential) refrigerant and allows for several operational benefits:
- energy efficiency is improved by 10%, thus enabling water temperature of up to 75 degrees Celsius.
- R290 usage provides compliance alongside the European F-Gas Regulation which focuses on phasing down refrigerant environmental impact.
- Rinnai’s R290 air source heat pump range is available in 11 different sizes, from 6 kW up to 50 kW. All units arrive with control systems that allow time sensitive programming and customization enabling specific customer requirements to be met.
Rinnai’s has a wide and comprehensive selection of unvented water heaters to add to and complement the existing range of cylinders solutions.
