Rinnai, manufacturer of the energy efficient range of Infinity continuous flow water heaters and a complete range of gas fired wall heaters, is providing a brand new heating and hot water solution to offices in Merthyr Tydfil, South Wales.

CST Renewables – the building services engineers – were keen to get to grips with installing a new system. This included a bespoke boiler and hot water heating package.

CST Renewables was established by Control and Service Technology in response to growing interest in the renewables market from clients looking to improve energy efficiencies and dramatically lower running costs. The company, based in the Welsh town of Bridgend, is an acknowledged specialist in the commercial market but also completes domestic installations, service and repair work.

The first UK installation of the Rinnai system was at a large office building where CST had been called to assess the best energy efficient replacement for a failing forced draught, flued modular boiler set up.

The old system was low efficiency and costing the client, a property leasing company, a substantial amount in repair bills annually. The building is rented to a variety of organisations and businesses such as call and administration centre businesses.

Mark Hillier-Rees of CST says: “It was obviously the site needed to move on to something more energy efficient. We removed the old boiler and replaced it with two new Rinnai boilers on a cascade system. The redundant flue was removed and we put in place the Rinnai co-axial flue.

“This new Rinnai system is highly efficient – and due to its lack of moving parts and easy maintenance has very low annual service costs.”

The large 100kW condensing heating boilers are ideal for providing heating to buildings such as the Merthyr Tydfil office block and are extremely flexible as they can also provide hot water when placed in a cylinder. The Rinnai boilers are also available in 50kW and 75kW sizes.

Chris Goggin, Associate Director, Rinnai UK comments: “There are clear benefits in terms of efficiencies, when considering heating and hot water as two separate systems. I am pleased that we can provide two high efficiency market leading products in one simple turnkey solution.”
