In the dynamic landscape of plumbing and heating solutions, efficiency and reliability are paramount, especially when tasked with equipping critical public institutions. This case study delves into the collaborative efforts of Lincoln Plumbing & Heating (LPH) and Newark Cylinders, showcasing their seamless synergy in addressing the heating and hot water system needs of Gainsborough Police Station.

Installation Brief

As part of the Government’s De-carbonisation Programme to be 100% Carbon Free by 2050, LPH was given a brief of what the client’s requirements are and a Performance Specification. This included the complete removal of the existing plant room equipment to include two large gas boilers and all associated pumps, motorised valves, and controls.

The new installation was designed by Willowtree Design Associates and consisted of Three 32.6kW Mitsubishi Air Source Heat Pumps, Twin Headed Grundfoss Pumps, Balancing Valves, Commissioning Stations, Copper Pipe Work ranging from 76mm to 54mm. One 1600Ltr Stainless Steel Buffer Vessel was also required, which was a major factor in this System’s Success.

The Buffer Vessel forms part of the system’s heat storage and when called upon by the system controls, contains a sufficient storage to satisfy the heating demand. Once the vessel’s thermostats detect that heat is being draw off, the Heat Pump will start up and re-heat the unit.

Solution & Production

For Newark Cylinders, the prospect of producing a more than average-sized Buffer Vessel was a challenge they were willing to take on. From a design aspect, Newark Cylinders’ Technical Sales Manager Tom Sharpe said that despite the size required, he described it as “a straightforward manufacturing job for the team.”

The Buffer Vessel design included a shell dimension of 1850mm x 1100mm with an insulation thickness of 50mm. Due to the scale of the Buffer Vessel, a 2.0mm thick sheet of stainless steel material was used. This is 1.0mm thicker than used when other products up to 450mm diameter are produced.

The Buffer Vessel required several key features, including a maximum working pressure of 4.0 BAR, four 3” female BSP heat input connections, two 2½”F BSP heat output connections, three thermostat pockets, and three 1/2” F BSP temperature gauge connections.
