MoD chooses rinnai hot water for shower blocks
Rinnai, the UK leader in hot water systems, has
recently completed an installation of 20 HDC 1500i

onsite fuel for all the Rinnai systems. Rinnai designed
the systems in close co-operation with the local
contractor who installed all the units – and the on-site
facilities management company.
